When the Fw 190 started flying operationally over France in August 1941 it was quickly proven to be superior in all but turn radius to the Royal Air Force's main front line fighter, the Spitfire Mk. V.[1] The 190 wrested air superiority away from the RAF until the introduction of the vastly improved Spitfire Mk. IX in July 1942 restored qualitative parity.[2] The Fw 190 made its air combat debut on the Eastern Front in November/December 1942. Soviet pilots regarded the Bf 109 as the greatest threat in combat on the Eastern Front; nevertheless, the Fw 190 made a significant impact. The fighter and its pilots proved just as capable as the Bf 109 in aerial combat, and in the opinion of German pilots that flew both German fighters, the Fw 190 presented increased firepower and manoeuvrability at low to medium altitude.
The Fw 190 became the backbone of Jagdwaffe (Fighter Force) along with the Bf 109. On the Eastern Front the Fw 190 was versatile enough to be used in Schlachtgeschwader (Battle Wings or Strike Wings), specialised ground attack units which achieved much success against Soviet ground forces. As an interceptor, the Fw 190 underwent improvements to make it effective at high altitude allowing the 190 to maintain relative parity against its Allied opponents. The Fw 190A series' performance decreased at high altitudes (usually 6,000 m (20,000 ft) and above) which reduced its effectiveness as a high-altitude interceptor, but this problem was mostly rectified in later models, particularly in the Junkers Jumo 213 inline-engine powered Focke-Wulf Fw 190D series, which was introduced in September 1944. In spite of its successes, it never entirely replaced the Bf 109.
The Fw 190 was well-liked by its pilots. Some of the Luftwaffe's most successful fighter aces flew the Fw 190, including Otto Kittel with 267 victories, Walter Nowotny with 258 victories and Erich Rudorffer with 222 claimed kills. A great many of their kills were claimed while flying the Fw 190.

Early development
Genesis
In autumn 1937, the Reichsluftfahrtministerium (RLM) ("Reich Air Ministry") asked various designers for a new fighter to fight alongside the Messerschmitt Bf 109, Germany's front line fighter. Although the Bf 109 was an extremely competitive fighter, the RLM was worried that future foreign designs might outclass it and wanted to have new aircraft under development to meet these possible challenges.[3] Kurt Tank responded with a number of designs, most incorporating liquid-cooled inline engines. However, it was not until a design was presented using the air-cooled, 14-cylinder BMW 139 radial engine that the RLM's interest was aroused. It was believed that because the Fw 190 used a radial engine it would not affect production of the Bf 109, furthering the RLM's interest in the Fw 190.[4] At the time, the use of radial engines on land-based fighters was relatively rare in Europe, as it was believed that their large frontal area would cause too much drag on a design as small as a fighter. Tank was not convinced of this, having witnessed the success of radial engines as used by the US Navy, and felt a properly streamlined installation would eliminate this problem.[4]Kurt Tank himself outlined the reasoning for his design:
In response to the perceptions about radial-engine aircraft, Tank's solution was to tightly cowl the engine in its entirety. Normally, radial engines would be left open at the front, in order to allow in sufficient air to cool the engine. Instead, Tank's cowl completely enclosed the engine. Cooling air was admitted through a hole in the front of an oversized propeller spinner; a cone in the middle of the hole was intended to compress the air, allowing the small opening to create sufficient airflow. In theory, the tight-fitting cowling also provided some thrust due to the compression and heating of air at speed through the cowling.[6]The Messerschmitt 109 [sic] and the British Spitfire, the two fastest fighters in world at the time we began work on the Fw 190, could both be summed up as a very large engine on the front of the smallest possible airframe; in each case armament had been added almost as an afterthought. These designs, both of which admittedly proved successful, could be likened to racehorses: given the right amount of pampering and easy course, they could outrun anything. But the moment the going became tough they were liable to falter. During World War I, I served in the cavalry and in the infantry. I had seen the harsh conditions under which military equipment had to work in wartime. I felt sure that a quite different breed of fighter would also have a place in any future conflict: one that could operate from ill-prepared front line airfields; one that could be flown and maintained by men who had received only short training; and one that could absorb a reasonable amount of battle damage and still get back. This was the background thinking behind the Focke-Wulf 190; it was not to be a racehorse but a Dienstpferd, a cavalry horse.[5]
After the war, Tank denied a rumour that he had to "fight a battle" with the RLM to convince them of the radial engine's merits. In fact, the RLM favoured a radial engine fighter, as it meant it would not disrupt or divert production of the Bf 109's Daimler-Benz powerplant.[7]
First prototypes
A main feature of the Fw 190 was its wide landing gear. Tank appreciated that operating from primitive airfields in wartime would require stable undercarriage—a lesson learned from witnessing the difficulty of moving machinery in the First World War. The undercarriage was designed to withstand sinking speeds of 15 feet (4.5 metres) per second. This doubled the strength factor. The Fw 190 was thus more easily operated and suffered fewer accident rates than the Messerschmitt Bf 109 with its closely spaced landing gear. The undercarriage braking system was hydraulically activated.[9] The cockpit location, directly behind the engine, resulted in a cockpit that became uncomfortably hot. During the first flight, the temperature reached 55 °C (131 °F), after which Focke Wulf's chief test pilot, Hans Sander commented, "It was like sitting with both feet in the fireplace."[10] Flight tests soon showed that the expected benefits of Tank's cooling design did not occur, so after the first few flights, this arrangement was replaced by a smaller, more conventional spinner that only covered the hub of the three-blade VDM propeller. In an attempt to increase airflow over the tightly-cowled engine, a 10-blade fan—later replaced with a 12-blade fan—was fitted at the front opening of the redesigned cowling and was geared to be driven at 3.12 times engine speed. This quickly became standard on the 190 and nearly all other German aircraft powered by the BMW 801.[11] In this form the V1 first flew on 1 December 1939, having been repainted with the Luftwaffe's Balkenkreuz and with the Stammkennzeichen (factory code).[12] RM+CA.[13]
The Fw 190 V2 FL+OZ (later RM+CB) first flew on 31 October 1939 and was equipped from the outset with the new spinner and cooling fan. It was armed with one Rheinmetall-Borsig 7.92 mm (.312 in) MG 17 machine gun and one 13 mm (.51 in) MG 131 machine gun in each wingroot.[13]
The design team used rods to actuate the control surfaces, instead of the usual cables, which tended to stretch; the resulting 'give' or 'play' of the stretched cables making the controls less crisp and responsive. Another innovation was to make the controls as light as possible. The maximum resistance for the aileron's controls had to be eight pounds, as the average man's wrist could not exert a greater force. Once the controls were correctly balanced, it was important that they stayed that way over a variety of speeds. A fighter pilot did not want to have to re-trim the aircraft in flight every time he changed the throttle settings. The design team were so successful in this regard that they found that movable trim tabs were not necessary. Small tabs were fitted to all control surfaces and adjusted on the ground after the initial test flights, to compensate for wide tolerances, typical in mass produced aircraft. The elevators were the only control surfaces that needed to be trimmed in flight; this was achieved using an all-moving tailplane that was electrically adjustable from a -3 to a +5 angle of incidence.[14] The empennage featured relatively small horizontal and vertical surfaces. The rudder and elevators, like the ailerons, had ground-adjustable tabs only.[15]
Another aspect of the new design was the extensive use of electrically-powered equipment instead of the hydraulic systems used by most aircraft manufacturers of the time. On the first two prototypes the main undercarriage was hydraulic. Starting with the third prototype, the undercarriage was operated by push buttons in the cockpit controlling electric motors in the wings, and was kept in position by electric up and down locks.[16] The armament was also charged and fired electrically. Tank believed that service use would prove electrically-powered systems would be more reliable and more rugged than hydraulics; electric lines being much less prone to damage from enemy action.[15]
The BMW 801 engine and its Kommandogerät
Even before the first flight of the Fw 190 V1, BMW was bench testing a larger, more powerful 14-cylinder two-row radial engine, the BMW 801. This engine introduced an engine management system called Kommandogerät: in effect, a mechanical computer which set mixture, propeller pitch (for the constant speed propeller), boost, and magneto timing. This reduced the pilot's work load to the throttle control only. The device was named the Kommandogerät, or "brain box". The drawback was slight and minor surges that made the Fw 190 harder to fly in close formations.[17] In the initial development phase, Tank asserted the device did not work well. One of the faults in the system was the violent switching in of the high gear of the supercharger as the aircraft climbed. During a test flight Tank carried out a loop at medium altitude. Just as he was nearing the top of the loop, at 2,650 m (8,700 ft), the supercharger's high gear kicked in with a jerk. The Fw 190 was on its back, with little airspeed. The sudden change in torque hurled the aircraft into a spin in which a pilot would quickly become disoriented. On this particular flight Tank's artificial horizon toppled (the cause is not explained). Although Tank did not know whether he was in an upright, or inverted spin he managed to recover after a loss of altitude. The rough transition was smoothed out and the device was made to work very well.[18]Later prototypes
On the V5 the sliding canopy was redesigned by replacing the rear Plexiglas glazing with duralumin panels. The vertical tail shape was also changed and the rudder tab was replaced by a metal trim strip adjustable only on the ground. New, stiffer undercarriage struts were introduced, along with larger diameter wheels. The retraction mechanism was changed from hydraulic to electrically powered and new fairings of a simplified design were fitted to the legs.[13] At first, the V5 used the same wings as the first two prototypes, but to allow for the larger tyres, the wheelwells were enlarged by moving forward part of the leading edge of the wing root; the wing area became 15.0 m² (161 ft²). In this form this prototype was called the V5k for kleine Fläche (small wing).[20] The V5 first flew in the early spring of 1940.
However, the weight increase was substantial, 635 kg (1,400 lb), leading to higher wing loading and a deterioration in handling. As a result, following a collision with a ground vehicle in August 1940 that sent the V5 back to the factory for major repairs, it was rebuilt with a new wing which was less tapered in plan than the original design; it had a larger area, 18.30 m² (197 ft²), and now spanned 10.506 m (34 ft 5 in); the aircraft was now called the V5g for große Fläche (large wing). Although it was 10 km/h (6 mph) slower than when fitted with the small wing V5g was much more manoeuvrable and had a faster climb rate.[20] This new wing platform was to be used for all major production versions of the Fw 190.[13]
Even with the new engine and the cooling fan, the 801 suffered from high rear row cylinder head temperatures, which in at least one case resulted in the detonation of the fuselage-mounted MG 17 ammunition. One other shortcoming of the cockpit location was a poor over-the-nose view which led to handling problems on the ground. More than one ground crash resulted from lack of familiarity with the new aircraft.
Fw 190 A-0 were the pre-production series ordered in November 1940. 28 of these were built; because they were built before the new wing design was fully tested and approved, the first nine of the Fw 190 A-0 had small wings. All were armed with two synchronised 7.92 mm (.312 in) MG 17 machine guns mounted in the forward fuselage, one MG 17 in each wing root, and one MG 17 in each of the outboard wings. In detail, they were different from later A-series Fw 190s: they had shorter spinners, the armoured cowling ring was a different shape, with a scalloped hinge on the upper, forward edge of the upper engine cowling, and the bulges covering the interior air intakes on the engine cowlings were symmetrical "teardrops". Also, the panels aft of the exhaust pipes had no cooling slots. Several of these aircraft were later modified for testing engines and special equipment.[13]
Engine reliability
Engine problems plagued the 190 for much of its early development, and the entire project was threatened several times with a complete shutdown. If not for the input of Oberleutnants Karl Borris and Otto Behrens, both of whom had enlisted in the Luftwaffe as mechanics, the Fw 190 program might have died before reaching the front lines. Borris and Behrens could see past the limitations of the Fw 190 and the 801 and envisioned a formidable fighter. During several RLM commissions that wished to terminate the program, both men indicated that the Fw 190's outstanding qualities outweighed its deficiencies.[21]The first unit to be equipped with the A-0 was Erprobungsstaffel 190, formed in March 1941 to help iron out any technical problems and approve the new fighter before it would be accepted for full operational service in mainstream Luftwaffe Jagdgeschwader. At first this unit, commanded by Oblt. Behrens, was based at Rechlin, but it was soon moved to Le Bourget. Some 50 modifications were required before the RLM approved the Fw 190 for deployment to Luftwaffe units.[21]
Engine reliability problems, particularly overheating, continued to plague the Fw 190 until spring 1942, and the availability of the BMW 801 C-2 engine in the Fw 190 A-2. A related problem was the lower cylinder of the rear bank, which suffered broken connecting rods due to overheating. The problem was resolved by rerouting part of the exhaust system, a method discovered by III./JG 26's Technical Officer ("T.O.") Rolf Schrödeter. To quickly implement the fix, it was found the re-routing could be done easily in Gruppe workshops. The reduction in temperature affecting the bottom cylinder went a long way to solving the problem.[22][23]
Fw 190 A
A-1 to A-3
The first of the A-2s appeared in October 1941 and were equipped with the improved BMW 801 C-2 which was still rated at 1,560 PS (1,539 hp, 1,147 kW).[26] The addition of new ventilation slots on the side of the fuselage further aided cooling. The re-routed exhaust system devised by Oblt. Schrödeter resolved most of the overheating problems. There were 13 exhausts for the 14 cylinders; eight of these were grouped to exit, four on each side, along the forward fuselage, just above the leading edge of the wing; under the forward centre section, between the undercarriage bays were five exhaust stacks, with cylinders 9 and 10 sharing a common pipe.[27] The A-2 wing weaponry was updated, with the two wing root-mounted 7.92 mm (.312 in) MG 17s being replaced by 20 mm MG 151/20E cannons.[26] With the introduction of the new cannons, the Revi C12/C gunsight was upgraded to the new C12/D model. The introduction of the A-2 marked a shift in air supremacy from the British, with their Spitfire Mk. V, to the Germans.[26][N 1] German production records make no real distinction between A-2s and A-3s, which were very similar aircraft: the total combined A-2 and A-3 production was 910 airframes built between October 1941 and August 1942.[28] In addition to Focke-Wulf and AGO, a new subcontracter, Arado, built A-2s and A-3s at Warnemünde.[26]
The A-3 was equipped with the BMW 801 D-2 engine, which increased power to 1,700 PS (1,677 hp, 1,250 kW) at takeoff by improving the supercharger and raising the compression ratio. Because of these changes, the A-3 model required a higher octane fuel—100 (C3) versus 87 (B4).[27] The A-3 retained the same weaponry as the A-2.[29] The A-3 also introduced the Umrüst-Bausätze factory conversion sets. The Fw190A-3/U1 and U2 were single experimental Fw 190s: U1 (W.Nr130270) was the first 190 to have the engine mount extended by 15 cm (6 in). The U2 (W.Nr 130386) had RZ 65 73 mm (2.87 in) rocket launcher racks under the wings with three rockets per wing. There were also a small number of U7 aircraft tested as high-altitude fighters armed with only two 20 mm MG 151 cannons, but with reduced overall weight.[30]
The Fw 190A-3/U3 was the first of the Jabo (Jagdbomber), using an ETC-501 centreline bomb rack able to carry up to 500 kg (1,100 lb) of bombs or, with horizontal stabilising bars, one 300 L (80 US gal) drop tank. The U3 retained the fuselage-mounted 7.92 mm (.312 in) MG 17s and the wing-mounted 20 mm MG 151 cannons, with the outer MG FF being removed.[30] [N 2]
The Fw190A-3/U4 was a reconnaissance version with two RB 12.5 cameras in the rear fuselage and a EK 16 gun camera or a Robot II miniature camera in the leading edge of the port wing root. Armament was similar to the U3, however and the ETC 501 was usually fitted with a 300 L (80 US gal) drop tank.[30] See A-2 for production numbers.[31]
In Autumn 1942, a political decision diverted 72 new aircraft off the production lines for delivery to Turkey in an effort to keep that country friendly with the Axis powers. These were designated Fw 190 A-3a (a=ausländisch (foreign), designation for export models) and these were delivered between October 1942 and March 1943. The Turkish aircraft had the same armament as the A-1: four 7.92 mm (.312 in) MG 17 machine guns and two 20 mm MG FF cannon. There was no FuG 25 IFF device in the radio equipment.[30]
In later years, the high-altitude performance of the Fw 190A was found to be inadequate. As a result GM-1 Nitrous oxide boost was introduced to provide more power at altitude.[32]
A-4 to A-6
The U1 was outfitted with an ETC 501 rack under the fuselage. All armament except for the MG 151 cannons was removed. The U3 was very similar to the U1 and later served as the Fw 190 F-1 assault fighter. Some U3s used for night operations had a landing light, mounted in the leading edge of the left wingroot. The U4 was a reconnaissance fighter, with two Rb 12.4 cameras in the rear fuselage and an EK 16 or Robot II gun camera. The U4 was equipped with fuselage-mounted 7.92 mm (.312 in) MG 17s and 20 mm MG 151 cannons. The U7 was a high-altitude fighter, easily identified by the compressor air intakes on either side of the cowling. Adolf Galland flew a U7 in the spring of 1943.
The A-4/U8 was the Jabo-Rei (Jagdbomber Reichweite, long-range fighter-bomber), adding a 300 L (80 US gal) drop tank under each wing, on VTr-Ju 87 racks with duralumin fairings produced by Weserflug, and a centreline bomb rack. The outer wing-mounted 20 mm MG FF/M cannons and the cowling-mounted 7.92 mm (.312 in) MG 17 were removed to save weight. The A-4/U8 served as the model for the Fw 190 G-1.
A new series of easier to install Rüstsatz field kits began to be produced in 1943. The first of these, the A-4/R1 was fitted with a FuG 16ZY radio set with a Morane "whip" aerial fitted under the port wing. These aircraft were called Leitjäger or Fighter Formation Leaders that could be tracked and directed from the ground via special R/T equipment called Y-Verfahren. More frequent use of this equipment was made from the A-5 onwards.[33] The Fw 190A-4 could achieve 1,700 hp (2,100 with MW-50 boost). Its maximum speed was 416 mph (670 k/ph) at 20,590 ft (6,250 m). Operational ceiling was 37,400 ft (11,400 m). Normal range was 497 miles (800 km). Normal takeoff weight was 8,378 lb (3,800 kg).[34] The D series improved on the Fw 190 series; with MW-50 injection it could achieve 2,240 hp and a top speed of 426 mph (680k/ph) at 21,326 ft. At 33,000 ft, the D-9 could reach 397 mph.[19] A total of 976 A-4s were built between June 1942 and March 1943.[35]
The A-5 was developed after it was determined that the Fw 190 could easily carry more ordnance. The engine was moved forward by 15 cm (6 in), and the aircraft was equipped with the BMW 801 D-2 engine, rated at 1,700 PS (1,677 hp, 1,250 kW). Some A-5s were tested with the MW 50 installation: this was a mix of 50% methyl alcohol and 50% water which could be injected into the engine to produce a short-term power boost to 2,000 PS (1,973 hp, 1,471 kW), but this system was not adopted for serial production. New radio gear, including FuG 25a Erstling IFF and an electric artificial horizon found their way into the A-5.[33] The A-5 retained the same basic armament as the A-4. The A-5 too, saw several Umrüst-Bausätze kits. The U2 was designed as a night Jabo-Rei and featured anti-reflective fittings and exhaust flame dampeners. A centreline ETC 501 rack typically held a 250 kg (550 lb) bomb, and wing-mounted racks mounted 300 L drop tanks. A EK16 gun camera, as well as landing lights, were fitted to the wing leading edge. The U2 was armed with only two 20 mm MG 151 cannons. The U3 was a Jabo fighter fitted with ETC 501s for drop tanks and bombs; it too featured only two MG 151s for armament. The U4 was a "recon" fighter with two RB 12.5 cameras and all armament of the base A-5 with the exception of the MG FF cannons. The A-5/U8 was another Jabo-Rei outfitted with SC-250 centreline mounted bombs, underwing 300 litre drop tanks and only two MG 151s; it later became the Fw 190 G-2. A special U12 was created for bomber attack, outfitted with the standard 7.92 mm (.312 in) MG 17 and 20 mm MG 151 but replacing the outer wing 20 mm MG-FF cannons with two underwing gun pods containing two 20 mm MG 151/20 each, for a total of two machine guns and six cannons. The A-5/U12 was the prototype installation of what was known as the R1 package from the A-6 onwards. The A-5/R11 was a night fighter conversion fitted with FuG 217 Neptun (Neptune) radar equipment with arrays of three dipole antenna elements vertically mounted fore and aft of the cockpit and above and below the wings. Flame-dampening boxes were fitted over the exhaust exits. There were 1,752 A-5s built from November 1942 to June 1943.[36]
The Fw 190 A-6 was developed to address shortcomings found in previous "A" models when fighting U.S. heavy bombers. Modifications of the type to date had caused the weight of the aircraft to creep up. To combat this and to allow better weapons to be installed in the wings, a structurally redesigned and lighter wing was introduced with the A-6. The normal armament was increased to two MG 17 fuselage machine guns and four 20 mm MG 151/20E wing root and outer wing cannon with larger ammunition boxes. New electrical sockets and reinforced weapon mounts were fitted internally in the wings to allow the installation of either 20 mm or 30 mm (1.18 in) ammunition boxes and for underwing armament. Because the outer wing MG 151s were mounted lower than the MG/FFs new larger hatches, incorporating bulges and cartridge discharge chutes, were incorporated into the wing lower surfaces. It is believed the MG 17s were kept because their tracer rounds served as a targeting aid for the pilots. A new FuG 16 ZE radio navigation system was fitted in conjunction with a FuG 10 ZY. A loop aerial for radio navigation, mounted on a small "teardrop" base was fitted under the rear fuselage, offset slightly to port, with an additional short "whip" aerial aft of this. These aerials were fitted on all later Fw 190 variants. In late 1943, the Erla Antwerp factory designed a more simple rack/drop tank fitting, which was more streamlined than the bulky ETC 501 and could be quickly fitted or removed. Several A-6s, A-7s and A-8s of JG 26 were fitted with these racks (one aircraft so fitted was A-8 W.Nr.170346 Black 13 flown by Obstlt. Josef Priller during the Normandy invasion on 6 June 1944.) The A-6 was outfitted in numerous ways with various sets, Rüstsätze (field modification kits): more flexible than the factory upgrade kits for previous versions, these field upgrade kits allowed the A-6 to be refitted in the field as missions demanded. At least 963 A-6s were built between July 1943 ending in April 1944 according to RLM acceptance reports and Focke-Wulf production books.
A-7 to A-8
The Fw 190 A-8 entered production in February 1944, powered either by the standard BMW 801 D-2 or the 801Q (also known as 801TU). The 801Q/TU was a standard 801D with improved, thicker armour on the front annular cowling, which also incorporated the oil tank, upgraded from 6 mm (.24 in) on earlier models to 10 mm (.39 in). Changes introduced with the Fw 190 A-8 also included the C3-injection Erhöhte Notleistung emergency boost system to the fighter variant of the Fw 190 A (a similar system with less power had been fitted to some earlier Jabo variants of the 190 A) raising power to 1,980 PS (1,953 hp, 1,456 kW) for a short time. The Erhöhte Notleistung system operated by spraying additional fuel into the fuel/air mix, cooling it and allowing higher boost pressures to be run, but at the cost of much higher fuel consumption. From the A-8 on Fw 190s could be fitted with a new paddle-bladed wooden propeller, easily identified by its wide blades with curved tips. A new outwardly-bulged main canopy glazing format, more in the manner of a Malcolm hood rather than a bubble canopy, with greatly improved vision sideways and forward had been developed for the F-2 ground attack model, but was often seen fitted at random on A-8s, F-8s and G-8s. The new canopy included a larger piece of head armour which was supported by reinforced bracing and a large fairing. A new internal fuel tank with a capacity of 115 L (30 US gal) was fitted behind the cockpit, which meant that the radio equipment had to be moved forward to just behind the pilot. Externally, a large round hatch was incorporated into the lower fuselage to enable the new tank to be installed and the pilot's oxygen bottles were moved aft and positioned around this hatch. A fuel filler was added to the port side, below the rear canopy and a rectangular radio access hatch was added to starboard. Other changes included an ETC 501 underfuselage rack which was mounted on a lengthened carrier and moved 200 mm (8 in) further forward to help restore the centre of gravity of the aircraft. This fuselage would form the basis for all later variants of the Fw 190 and the Ta 152 series. The Morane "whip" aerial for Y-Verfahren was fitted as standard under the port wing, just aft of the wheelwell. Nearly a dozen Rüstsätze kits were made available for the A-8, including the famous A-8/R2 and A-8/R8 Sturmbock models. The A-8/R2 replaced the outer wing 20 mm cannon with a 30 mm (1.18 in) MK 108 cannon, the A-8/R8 was similar but fitted with heavy armour including 30 mm (1.18 in) canopy and windscreen armour and 5 mm ( in) cockpit armour. The A-8 was the most numerous of the Fw 190 As, with over 6,550 A-8 airframes produced from March 1944 to May 1945. A-8s were produced by at least eight factories during its lifetime.[38]
A-9
The Fw 190 A-9 was the last A-model produced, and was first built in September 1944. The A-9 was fitted with the new BMW 801S, called the 801 TS or 801 TH when shipped as a Kraftei, or "power egg", unitized engine installation (an aircraft engine installation format embraced by the Luftwaffe for a number of engine types on operational aircraft, in part for easy field replacement) rated at 2,000 PS (1,973 hp, 1,471 kW); the more powerful 2,400 PS (2,367 hp, 1,765 kW) BMW 801F-1 was not available. The armour on the front annular cowling, which also incorporated the oil tank, was upgraded from the 6 mm (.24 in) on earlier models to 10 mm (.39 in). The 12-blade cooling fan was initially changed to a 14-blade fan, but it consumed more power to operate and did not really improve cooling; thus BMW reverted to the 12-blade fan. The A-9 cowling was slightly longer than that of the previous Anton due to a larger annular radiator for the oil system. The bubble canopy design with the larger head armour was fitted as standard. Three types of propeller were authorised for use on the A-9: the VDM 9-112176A wooden propeller, 3.5 m (11 ft 6 in) in diameter, was the preferred option, however, many A-9s were fitted with the standard VDM 9-12067A metal propeller and some had a VDM 9-12153A metal propeller with external, bolt on balance weights.[39] The A-9 was also designed originally as an assault aircraft, so the wing leading edges were to have been armoured; however this did not make it past the design stage in order to save weight. The A-9 was very similar to the A-8 in regards to the armament and Rüstsätze kits. A total of 910 A-9s were built between April 1944 and May 1945, mostly in Focke Wulf's Cottbus factory.[40]In total about 13,291 Fw 190 As were produced in all variants.[41] However it is important to note that this number may include rebuilt or modified airframes from earlier aircraft. The Luftwaffe frequently changed between models on the production line. It was not uncommon to see an A5 be converted into an A7 or A8 aircraft. This is especially true of battle damaged aircraft that were repaired and upgraded to the version which the factory was currently manufacturing.
High-altitude developments
Limitations of A series
An attempt was made with the Fw 190 A-10, which was to have begun arriving in pilots' hands by March 1945 and was to be fitted with larger wings for better maneuverability at higher altitudes which, due to internal space, could have allowed additional 30 mm (1.18 in) calibre, long-barreled MK 103 cannons to be fitted. The A-10 was to be powered by the 801 F engine. However, due to the priority given to the Dora variant of the Fw 190 and the new Ta 152, the A-10 never made it past the prototype stage.[42]
High altitude improvements
Tank started looking at ways to address this problem early in the program. In 1941 he proposed a number of versions featuring new powerplants, and he suggested using turbochargers in place of superchargers. Three such installations were outlined; the Fw 190 B with a turbocharged BMW 801, the Fw 190 C with a turbocharged Daimler-Benz DB 603, and the Fw 190 D with a supercharged Junkers Jumo 213. The aircraft would also include pressurized cockpit and other features making them more suitable for high-altitude work. Prototypes for all three models were ordered.[43]Fw 190 V12 (an A-0) would be outfitted with many of the elements which eventually led to the B series. As it was based on the same BMW 801 engine as the A models, airframe modifications were relatively minor. These included a pressurised cockpit, which doubled the panes of glass in the canopy so that hot air could be forced between them to prevent icing, and the addition of the GM 1 nitrous oxide injection system. Several problems were encountered during the machine's flight and ground trials, mostly caused by the pressurisation system for the cockpit, and for this reason, the first B-series testbed airframe was retired from active service in late 1942. However, trials on other aircraft continued in early 1943, when the first few Fw 190 A-1s were modified into testbeds. The same aircraft used for testing the pressurized cockpits were also used to test larger wings (20.3 m²/219 ft² versus the standard 18.3 m²/197 ft² wing), which seriously affected the studies on pressurised cockpits. Following these studies, one additional Fw 190 B was built, named the B-1. This aircraft was similar to the B-0 but had slightly different armament. In its initial layout the B-1 was to be fitted with four 7.92 mm (.312 in) MG 17s and two 20 mm MG-FFs. One was fitted with two MG 17s, two 20 mm MG 151s and two 20 mm MG-FFs. After the completion of W.Nr. 811, no further Fw 190 B models were ordered.
The C model's use of the longer DB 603 engine required more extensive changes to the airframe. As the weight was distributed further forward, the tail of the aircraft had to be lengthened in order to maintain the desired centre of gravity. To test these changes, several examples of otherwise standard 190 As were re-engined with a supercharged DB 603 to experiment with this engine fit, V13 (W.Nr. 0036) with the 1,750 PS 603A, the similar V15 and V16, a 1,800 PS 603 E being fitted to the latter after a time. With this engine the V16 was able to reach 725 km/h (450 mph) at 6,800 m (22,310 ft), a considerable improvement over the 650 km/h (400 mph) at 5,200 m (17,060 ft) of the basic A models. V18 followed, the first to feature the full high-altitude suite of features including the pressurized cockpit, longer wings, a 603G engine driving a new four-blade propeller, and a Hirth 9-2281 turbocharger. Unlike the experimental B models, V18 had a cleaner turbocharger installation, running the required piping along the wing root, partially buried in the fillet, and installing both the turbocharger air intake and intercooler in a substantially sized teardrop shaped fairing under the cockpit.[44] This "pouch" led to the "Känguruh" (Kangaroo) nickname for these models. V18 was later modified to the V18/U1, with a "downgraded" 603A engine but a new DVL turbocharger that improved power to 1,600 PS at an altitude of 10,700 m (35,105 ft). Four additional prototypes based on the V18/U1 followed: V29, V30, V32 and V33.
Like the C models, the early examples of the D models were built primarily to test fit the Jumo 213 engine to the existing airframe, as the D-0, with plans to move on to definitive high-altitude models later, the D-1 and D-2. The first D-0 prototype was completed in October 1942, consisting of an A-5 airframe with the Jumo 213A engine. Further examples followed, but like the C models the development was stretched out.
Fw 190D
Fw 190D-9
The liquid-cooled 1,750 PS (1,726 hp, 1,287 kW) Jumo 213A could produce 2,100 PS (2,071 hp, 1,545 kW) of emergency power with MW 50 injection, improving performance to 426 mph (686 km/h) at 21,650 ft (6,600 m). Early D-9s reached service without the MW 50 installation, but in the meantime Junkers produced a kit to increase manifold pressure (Ladedrucksteigerungs-Rüstsatz) that increased engine output by 150 PS to 1,900 PS, and was effective up to 5,000 m (16,400 ft) altitude. It was fitted immediately to D-9s delivered to the units from September, or retrofitted in the field by TAM. By the end of December, all operational Doras, 183 in total, were converted.[46] From November 1944, a simplified methanol water (MW 50) system (Oldenburg) was fitted, which boosted output to 2,100 PS. By the end of 1944, 60 were delivered with the simplified MW 50 system or were at the point of entering service. The 115 L tank of the Oldenburg system would hold the MW 50 booster liquid, which was single purpose, while later systems were to be dual purpose, holding either MW 50 or additional fuel.[47]
The fighter lacked the high turn rate and higher rate of roll of its close coupled radial-engined predecessor. It was a bit faster, however, with a maximum speed of 680 km/h (422 mph) at 6,600 meters (21,650 ft). Its 2,240 horsepower with methanol-water injection (MW 50) gave it an excellent acceleration in combat situations. It also climbed and dived more rapidly than the Fw 190A, and so proved well suited to the dive-and-zoom ambush tactics favored by the Schlageter pilots. Many of the early models were not equipped with tanks for methanol, which was in very short supply in any event. At low altitude, the top speed and acceleration of these examples were inferior to those of Allied fighters. Hans Hartigs recalled that only one of the first batch of Dora 9s received by the First Gruppe had methanol water injection, and the rest had a top speed of only 590 km/h (360 mph).[48]
Due to the failure of multiple attempts to create an effective next generation 190, as well as the comments of some Luftwaffe pilots, expectations of the Dora project were low. These impressions were not helped by the fact that Tank made it very clear that he intended the D-9 to be a stopgap until the Ta 152 arrived. These negative opinions existed for some time until positive pilot feedback began arriving at Focke-Wulf and the Luftwaffe command structure.[49] Sporting good handling and performance characteristics, the D-9 made an effective medium altitude, high speed interceptor, although its performance still fell away at altitudes above about 20,000 ft (6,100 m). When flown by capable pilots, the Fw 190D proved the equal of Allied types.[50][51]
In order to fit the new engine in the Fw 190 fuselage while maintaining proper balance, both the nose and the tail of the aircraft were lengthened, adding nearly 1.52 m (4.99 ft) to the fuselage, bringing the overall length to 10.192 m (33.438 ft) versus the 9.10 m (29.9 ft) of the late war A-9 series. The lengthened tail required a straight-sided bay, 30 cm (12 in) long, spliced in forward of the rear angled joint and tail assembly of the fuselage. To further aid balance the pilot's oxygen bottles were moved aft and located in the new bay. This gave the rear fuselage a "stretched" appearance.[52]
Furthermore, the move to a V12 engine from a radial engine required more components to be factored into the design, most significantly the need for coolant radiators (radial engines are air-cooled). To keep the design as simple and as aerodynamic as possible, Tank used an annular radiator (the AJA 180 L) installed at the front of the engine, similar to the configuration used in the Jumo powered versions of the Junkers Ju 88. The annular radiator with its adjustable cooling gills resembled a radial engine installation, although the row of six short exhausts stacks on either side of the elongated engine cowling showed that Jumo 213 was an inverted vee-12 engine.[53] While the first few Doras were fitted with the flat-top canopy, these were later replaced with the newer rounded top "blown" canopy first used on the A-8 model. With the canopy changes, the shoulder and head armour plating design was also changed. Some late model Doras were also fitted with the Ta 152 vertical stabilizer and rudder, often called "Big Tails" by the Luftwaffe ground crews and pilots, as seen on W.Nr. 500647 Brown 4 from 7./JG 26 and W.Nr. 500645 Black 6 from JG 2. The centreline weapons rack was changed to an ETC 504 with a simplified and much smaller mounting and fairing.[52]
Some Fw 190 Ds served as fighter cover for Me 262 airfields as the jet fighters were very vulnerable on takeoff and landing. These special units were known as Platzsicherungstaffel (airfield defence squadrons).[59] One unit, known as the Würger-Staffel (also nicknamed "Papageien Staffel"), was created in April 1944 by Leutnant Heinz Sachsenberg at the behest of Adolf Galland, and was part of JV 44. The role of the Staffel was to guard the airfield and JV 44's Messerschmitt Me 262s as they landed; as such the Fw 190s were supposed to take off before the jets and circle the airfield in pairs (a Rotte). However, to allow the 262s a clear run back to the airfield the 190s had to land before the jets, negating their protection.[60] To help anti-aircraft artillery protecting the airfields quickly identify friendly aircraft the undersurfaces of the Würger-Staffel 190s were painted red with narrow white stripes.[61]
Fw 190 D-11
17 Fw 190 D-11s were known to have been manufactured. This version was fitted with the uprated Jumo 213E series engine which was also used in the Ta-152 H series. Changes over the D-9 were the enlarged supercharger air intake on the starboard side cowling and the use of a wooden, broad-bladed VS 9 or 10 propeller unit utilizing three 9-27012 C-1 blades with a diameter of 3.6 m (11.8 ft). The 13 mm (.51 in) fuselage guns were removed, and the cowling redesigned by omitting the gun troughs and simplifying to a flat profile. Two 30 mm (1.18 in) MK 108 cannons were installed in the outer wings to complement the 20 mm MG 151s in the inboard positions. Of the 17 Dora-11s delivered, three can be accounted for. One, the best known, was Rote 4 (red 4) of JV 44's Platzschutz unit. Another, white chevron, was found at München-Riem, and may have served with JV 44 after serving at the Verbandsführerschule General der Jagdflieger (Training School for Unit Leaders) at Bad Wörishofen; it is not known if it was actually used operationally. A third, "white <61," was also found after the war at the Verbandsfuehrerschule General der Jagdflieger.[62]While the D-11 was under manufacture, work started on the Fw 190 D-12 and D-13 models. The D-12 and D-13s were based on the D-11 design, however the D-12 and D-13 were fitted with Motorkanone nose cannons firing through the propeller hub (the D-12 would be fitted with a 30 mm (1.18 in) MK 108 cannon and the D-13 would be fitted with a 20 mm MG 151/20 cannon). There were three test aircraft built for the D-12 line, V63, V64 and V65 but no production aircraft were built.
Fw 190 D-13
The Fw 190 D-13 started with the construction of two prototypes (W.Nr 732053 and W.Nr 7322054), and the 20 mm MG 151/20 cannon was found to be quite suited for the aircraft and was already well known to be effective against allied bombers, as well as an effective ground support weapon. Thus the Fw 190 D-13/R11 was selected to enter production. The D-13/R11 was fitted with all-weather flying equipment including the PKS12 and K-23 systems for steering and autopilot. The FuG 125 radio system, known as Hermine was fitted to the aircraft, as well as a heated windscreen. Pilots reported that due to the large amounts of torque produced by the engine, they usually used the steering system during the takeoff run as it helped with the rudder movements. The D-13 also introduced a hydraulic boost system for the ailerons, which was later used on the Ta 152.In all, the RLM called for 820 D-11 airframes to be built by Focke-Wulf Sorau, stating in early 1945, Fieseler Kassel was tasked to build 1,420 D-12s starting in the same time frame and the manufacture of the D-13 was passed to Arbeitsgruppe Roland [N 3] tasked with the construction of 1,060 airframes starting again in early 1945. For some yet unknown reason, production of the D-12 was cancelled in favour of the D-13 model. From evidence from the Oberkommando der Luftwaffe General Quartiermeister document Nr. 2766/45 of April 1945, it was known that 17 D-13s were more than likely built, but only two were known to be in service. A D-13 (Wk. Nr 836017) flown by the Geschwaderkommodore of JG 26, Franz Götz, an ace with 63 kills, was surrendered to the British at Flensburg, Northern Germany in May 1945.[64] This aircraft is still in existence, painted in its original colour scheme as Yellow 10, is thought to be airworthy and is currently located in the Flying Heritage Collection at Paine Field in Everett, Washington. This aircraft is one of the few existing Fw 190s with a provenance that can be traced continuously from its manufacture to the present time.[65]
Ground attack variants
Fw 190 F
The Fw 190 F-3 was based on the Fw 190 A-5/U17, which was outfitted with a centreline mounted ETC 501 bomb rack, and in the Fw 190 F-3/R1 and Fw 190 F-3/R-3, two double ETC 50 bomb racks under each wing or two similarly located 30 mm MK 103 cannons. The F-3 could carry a 66-Imp gal (300 liter) drop tank. A total of 432 Fw 190 F-3s were built.[66]
Due to difficulties creating an effective strafing Fw 190 F able to take out the Russian T-34 tank, the F-4 through F-7 models were abandoned, and all attempts focused on conversion of the Fw 190 A-8.
The Fw 190 F-8 differed from the A-8 model with a slightly modified injector on the compressor which allowed for increased performance at lower altitudes for several minutes. The F-8 was also outfitted with the improved FuG 16 ZS radio unit which provided much better communication with ground combat units. Armament on the Fw 190 F-8 was two 20 mm MG 151/20 cannon in the wing roots and two 13 mm (.51 in) MG 131 machine guns above the engine. According to RLM acceptance reports, at least 3,400 F-8s were built, and probably several hundred more were built in December 1944 and from February to May 1945. (Data for these months is missing and probably lost.)[citation needed] Dozens of F-8s served as various testbeds for anti-tank armament, including the WGr.28 280 mm air-to-ground missile, likely based on the projectiles from the Nbw 41 heavy ground barrage rocket system, and the 88 mm (3.46 in) Panzerschreck 2 rockets, Panzerblitz 1 and R4M rockets.
There were also several Umrüst-Bausätze kits developed for the F-8, which included the Fw 190 F-8/U1 long range JaBo, outfitted with underwing V.Mtt-Schloß shackles to hold two 300 L (80 US gal) fuel tanks. ETC 503 bomb racks were also fitted, allowing the Fw 190 F-8/U1 to carry one SC 250 bomb under each wing and one SC 250 bomb on the centreline.
The Fw 190 F-8/U2 torpedo bomber was outfitted with an ETC 503 bomb rack under each wing and a centreline mounted ETC 504. The U2 was also equipped with the TSA 2 A weapons sighting system that improved the U2's ability to attack seaborne target with a 1,543 lb (700 kg) BT 700.[66]
The Fw 190 F-8/U3 heavy torpedo bomber was outfitted with an ETC 502, which allowed it to carry one BT-1400 heavy torpedo (3,086 lb/1400 kg). Due to the size of the torpedo, the U3's tail gear needed to be lengthened. The U3 also was fitted with the 2,000 PS BMW 801S engine, and the tail from the Ta 152.[citation needed]
The Fw 190 F-8/U4, created as a night fighter, was equipped with flame dampers on the exhaust and various electrical systems such as the FuG 101 radio altimeter, the PKS 12 automatic pilot, and the TSA 2 A sighting system. Weapons fitted ranged from torpedoes to bombs[citation needed]; however, the U4 was outfitted only with two MG 151/20 cannon as fixed armament.
The Fw 190 F-9 was based on the Fw 190 A-9 but with the new Ta 152 tail unit, a new bulged canopy as fitted to late-build A-9s, and four ETC 50 or ETC 70 bomb racks under the wings. According to RLM acceptance reports, 147 F-9s were built in January 1945, and perhaps several hundred more from February to May 1945. (Data for these months is missing and probably lost.)[citation needed]
Fw 190 G
The Fw 190 G was built as a long-range attack aircraft (JaBo Rei, or Jagdbomber mit vergrösserter Reichweite). Following the success of the Fw 190 F as a Schlachtflugzeug (close support aircraft), both the Luftwaffe and Focke-Wulf began investigating ways of extending the range of the Fw 190 F. From these needs and tests, the Fw 190 G was born.There were four distinct versions of the Fw 190 G:
The Fw 190 G-1: The first Fw 190 Gs were based on the Fw 190 A-4/U8 JaBo Rei's. Initial testing found that if all but two wing root mounted 20 mm MG 151 cannons (with reduced ammunition load) were removed, the Fw 190 G-1 (as it was now called) could carry a 250 kg (550 lb) or 500 kg (1,100 lb) bomb on the centreline and, via an ETC 250 rack, up to a 250 kg (550 lb) bomb under each wing. Typically the G-1s flew with underwing fuel tanks, fitted via the VTr-Ju 87 rack. The FuG 25a IFF (identification friend/foe) was fitted on occasion as well as one of the various radio direction finders available at the time. With the removal of the fuselage mounted MG 17s, an additional oil tank was added to support the BMW 801 D-2 engine's longer run times.[citation needed]
The Fw 190 G-2: The G-2 was based on the Fw 190 A-5/U8 aircraft. The G-2s were similarly equipped to the G-1s; however, due to wartime conditions, the underwing drop tank racks were replaced with the much simpler V.Mtt-Schloß fittings, to allow for a number of underwing configurations. Some G-2s were also fitted with the additional oil tank in place of the MG 17s; however, not all were outfitted with the oil tank. Some G-2s were fitted with exhaust dampers and landing lights in the left wing leading edge for night operations.[citation needed]
The Fw 190 G-3: The G-3 was based on Fw 190 A-6. Like the earlier G models, all but the two wing root mounted MG 151 cannons were removed. The new V.Fw. Trg bombracks, however, allowed the G-3 to simultaneously carry fuel tanks and bomb loads. Because of the range added by two additional fuel tanks, the G-3's duration increased to two hours, 30 minutes. Due to this extra flight duration, a PKS 11 autopilot was fitted. Some G-3s built in late 1943 were also fitted with the a modified 801 D-2 engine which allowed for increased low-altitude performance for short periods of time. The G-3 had two primary Rüstsätze kits. The R1 replaced the V.Fw. Trg racks with WB 151/20 cannon pods. This gave the G-3/R1 a total of six 20 mm cannons. When fitted with the R1 kit, the G model's addition armor was typically not used, and the PKS11 removed. The G-3/R1 was used in both ground strafing and anti-bomber roles. The R5 was similar to the R1, but the V.Fw. Trg racks were removed, and two ETC 50 racks per wing were added. As with the R1, the additional armor from the base G model were removed, as was the additional oil tank. In some instances, the fuselage mounted MG 17s were refitted.[citation needed]
The Fw 190 G-8: The G-8 was based on the Fw 190 A-8. The G-8 used the same "bubble" canopy as the F-8, and was fitted with underwing ETC 503 racks that could carry either bombs or drop tanks. Two primary Rüstsätze kits were also seen on the F-8. The R4 kit was a planned refit for the GM 1 engine boost system, but never made it into production, and the R5 kit replaced the ETC 503 racks with two ETC 50 or 71 racks. Due to the similarities with the F-8, the G-8 was only in production for a short amount of time.[citation needed] Some Gs were field modified to carry 1,000 kg (2,210 lb), 1,600 kg (3,530 lb) and 1,800 kg (3,970 b) bombs. When this was done, the landing gear was slightly improved by enhancing the oleo struts and using reinforced tires.[citation needed]
Approximately 1,300 Fw 190 Gs of all variants were new built. Due to war conditions, the manufacturing environment, and the use of special workshops during the later years of the war, the actual number of G models built is almost impossible to determine. During the later years of the war, "composite" aircraft were often assembled. For example, the wings from a fuselage damaged aircraft and the fuselage from a wing damaged aircraft might be reassembled into a new aircraft and listed as a Fw 190G with a new serial number. The Fw 190 G-1 currently displayed at the National Air and Space Museum is one of these "composite" aircraft, built from the fuselage of a Fw 190 A-7.[67]
Trainer versions
As the Luftwaffe phased out older aircraft such as the Ju 87, and replaced them with the Fw 190, many pilots required flight training to make the transition as quickly and smoothly as possible. Thus was born the Schulflugzeug (literally "school airplane") training version of the Fw 190. Several old Fw 190 A-5s, and later in 1944, A-8s, were converted by replacing the MW 50 tank with a second cockpit. The canopy was modified, replaced with a new three-section unit that opened to the side, similar to the Bf 109. The rear portion of the fuselage was closed off with sheet metal. Originally designated Fw 190 A8-U1, they were later given the Fw 190 S-5 and S-8 designation. There were an estimated 58 Fw 190 S-5 and S-8 models converted or built.[68]-

Combat history, survivors and modern builds
Main article: Focke-Wulf Fw 190 operational history
The Fw 190 participated on every major combat front where the Luftwaffe operated, and did so with success. Some 28 Fw 190s are in museums or in the hands of private collectors around the world. In 1997, a German company began manufacturing new models.Production
A 0.40-km² (100 acre) Focke-Wulf plant at Marienburg produced approximately half of all Fw 190s and was bombed by the Eighth Air Force on 9 October 1944.[69]Operators
- The French Air Force ordered 64 aircraft postwar from the SNCA aircraft company. The Fw 190 A-5/A-6 model that was chosen carried the designation NC 900. The aircraft were used operationally for a short period and withdrawn due to problems with the BMW 801 engine.
- Royal Hungarian Air Force received a total of 72 Fw 190F-8s starting in the November 1944. They were operated by the 102. vadászbombázó század, later osztály (102nd Fighter-Bomber Squadron, later Wing) engaging close support missions on the Eastern Front in 1944–45.[70]
- Japanese Army Air Force received one Fw 190A-5 for evaluation purposes.[71]
- The Spanish Air Force operated Fw 190A-2,3,4 among Fw 190 A-8 and Gs with volunteers of Escuadrilla Azul (15ª Spanische Staffel, JG 51 "Mölders" VIII. Fliegerkorps, belonged in LuftFlotte 4) in Eastern Front (from Orel during September 1942 to Bobruisk, during July 1943) and Defense of the Reich over Germany.
- The Royal Romanian Air Force received from Germany a number of Fw 190 A-8s used for defensive purposes in metropolitan areas. Following the 23 August 1944 coup by King Michael, which resulted in Romania leaving the Axis powers, Romania interned 22 Luftwaffe Fw 190 F-8s which were operating from Romanian bases, using them for operations against German forces. Nine serviceable Fw 190s were later confiscated by the Soviet Union.[citation needed]
- The Turkish Air Force, beginning in mid-1942, received 72 examples of the Fw 190 A-3a (export model of A-3, a stood for ausländisch—foreign) from Germany to modernize their air force. These aircraft were basically Fw 190 A-3s, with BMW 801 D-2 engines and FuG VIIa radios and an armament fit of four MG 17s, with the option of installing two MG-FF/M cannon in the outer wing positions. The export order was completed between October 1942 and March 1943. The Fw 190 remained in service until 1948–49.
