While some may not agree with the order of the list, everyone should agree that each one of these aircraft hailed a groundbreaking point in aviation.
Rank 10 – F117 Stealth Fighter Year 1983
The first flight took place in 1981 but the aircraft remain a Military secret until 1988. The US Air Force had a total of 59 Nighthawks before retirement, starting in 2006 through to 2008, slowly removed the aircraft from the skies (read our previous post on the Retirement of The F-117 Nighthawk).
Also known as the Frisbee and the Wobblin’ Goblin, the Nighthawk, only used in night-time missions (hence the name), is unstable in flight but also highly maneuverable and almost invisible to radar.
The aircraft, powered by two low-bypass F404-GE-F1D2 turbofan engines from General Electric, is mainly constructed of aluminum, areas of the engine and exhaust systems consist of titanium.
The surfaces and edge profiles are optimized to reflect hostile radar into narrow beam signals, directed away from the enemy radar detector. All the doors and opening panels on the aircraft have saw-toothed forward and trailing edges to reflect radar.
Almost all the outer surface is coated with a Radar-Absorbent Material (RAM), even the rectangular air intakes on both sides of the fuselage are covered by gratings coated with RAM.
The aircraft does not rely on radar for navigation or targeting, instead the aircraft is equipped with Forward-Looking Infrared (FLIR) and a Downward-Looking Infrared (DLIR) with laser designator, supplied by Raytheon.
The fly-by-wire is supplied by BAE Systems Aircraft Controls. This system replaces manual control of the single seat aircraft, which is resumed by the pilot for weapon delivery.
The aircraft can carry a range of tactical fighter ordnance including; BLU-109B low-level laser-guided bomb, GBU-10 and GBU-27 laser-guided bomb units, Raytheon AGM-65 Maverick and Raytheon AGM-88 HARM air-to-surface missiles.
The F-117 Nighthawk has been in operational service in many missions including; Operation Just Cause, in Panama; during Operation Desert Storm, in Kosovo; in Afghanistan and during Operation Iraqi Freedom.
F-117′s are now being replaced in the USAF by the more effective F-22 Raptor and F-35 Lighting II.

Rank 9 – DR 1 Fokker Triplane Year 1917
Many say the aircraft was inspired by Sopwith Triplane however others claim “Reinhold had not even seen the Sopwith before he began designing the DR 1.”
After testing a prototype known as V.3, which suffered from severe wing vibration, Reinhold redesigned the next prototype, the V.4, with hollow struts between the wings. The final design, which came to be known as the DR1, also had improvements to the ailerons and elevators.
The Fokker Dr 1 had one open cockpit, which could hold one pilot and the airframe was made out of steel tubing covered in aircraft doped canvas.
The Dr 1 came equipped with two machine guns which had an intercepting gear that was designed to fire bullets through the propeller arc without hitting the blades.
The DR 1 was a smaller, more maneuverable plane compared to others of World War One; but it was not as fast as most others at that time.
It was in this plane that the most celebrated World War One pilot, Manfred, von Richthofen “The Red Baron”was reported to have made the last of his 80 confirmed victories.
Only 320 Fokker Dr 1′s were made in World War One, so no Fokker Dr 1 is still around today, there are only replicas.

Rank 8 – Mitsubishi Zero-Sen (A6M2) Year 1937
Manufactured by Mitsubishi Jukogyo & Nakajima, It was the first shipboard fighter capable of surpassing land-based aircraft was famous for its ability to outmaneuver other aircraft such as the
Brewster F2A Buffaloes, Curtiss P-40s and Grumman F4F Wildcats.
Because of the A6Ms exceptional range and performance, it was used in almost every military engagement in the Pacific, until the end of the war.
The Zero- Sen was armed with two 20-mm type 99 cannon, two 7.7mm type 97 machine guns, and possessed the incredible range of 1930 miles using a centerline drop tank.
The unveiling of the A6M2 came as a complete surprise to US forces even though Claire Chennault, the author of ‘The Role of Defensive Pursuit,’ and leader of the Flying Tigers had warned the USAAF about the dangers of Japanese air power.
Once the effectiveness and maneuverability became clear, Chennault was said to have constantly reminded his pilots, ‘Never try to turn with a Zero. Always get above the enemy and try to hit him with the first pass.’
It was only when US Navy PBY Catalina retrieved an almost perfectly intact A6M2, shot down during Pearl Harbor, were the short comings of the aircraft discovered.
The main failing of the A6M2, 3, and 5 fighter aircraft were the lack of armor for the pilot and its fuel tanks were not self sealing and once breached the aircraft was lost.
The consequent testing and of this unmatchable aircraft lead the American aircraft manufacturer Grumman, to lighten the Grumman F4F Wildcat, and install a larger engine on the Grumman F6F Hellcat.
An up until the introduction of the P-38 Lightning, the F6F Hellcat, and the F4U Corsair the A6M Zero remained the premier fighter aircraft in the Pacific.

Rank 7 – Harrier Jump Jet (AV-8B Harrier II) Year 1985
The Harrier family is the only truly successful design of this type from the many that arose in the 1960s.
The Harrier family is made up of four main versions:
- Hawker Siddeley Harrier – 1st generation Harrier, also known as the AV-8A Harrier.
- British Aerospace Sea Harrier – Maritime strike/air defense fighter aircraft.
- Boeing/BAE Systems AV-8B Harrier II – 2nd generation Harrier.
- BAE Systems/Boeing Harrier II – British variant of the 2nd generation Harrier.
These were developed directly from the Hawker P.1127 prototype which began after British aircraft manufacturer, Hawker Aircraft, came up with a design for a plane that could meet the current NATO specification for a “Light Tactical Support Fighter”.
The original P.1127 prototype made its first flight in 1960, the RAF ordered a modified version of the P.1127/Kestral in 1966, which became known as the Harrier GR.1.
The Harrier was extensively redeveloped by McDonnell Douglas and British Aerospace, leading to the AV-8B Harrier II and Harrier GR5/GR7/GR9,
The United States Marine Corps makes heavy use of its AV-8B and has developed into a number of sub-variants featuring upgraded systems, software, avionics and structural changes throughout.
While the Harrier is one of the most flexible aircraft ever made, the level of understanding and skill needed to pilot it is considerable.
Thanks to thrust vector and reaction control system, the Harrier is capable of forward flight as well as VTOL and STOL maneuvers; however this requires the skills and understanding associated with helicopters.
The four engine nozzle thrust vectors can be set between zero degrees (horizontal) and 98 degrees (down and slightly forwards), this allows the aircraft to take off and land vertically.
Despite the difficulties in piloting the aircraft, the AV-8B is a capable fighter armed with cannons and several varieties of air-to-air missiles. The AV-8B also doubles as great strike support, able to carry a large amount of stores on its six underwing hardpoints.
The Harrier AV-8B II is used currently by three nations; US, Spain and Italy. Briton’s RAF and Navy, also use its version of the Harrier II.

Rank 6 – F 86 Sabre Year 1949
The F-86 started out life as when two prototype XP-86s were contracted in late 1944, but large scale production did not begin until after WWII.
The first XP-86 prototype flew on 1 October 1947, powered by a 3,750-pound thrust G.E. J35 engine. It was re-engined with a more powerful G.E. J47 turbojet the following spring and was re-designated the YP-86A. With a more powerful engine top speed and ceiling of the new fighter increased significantly and the rate of climb almost doubled.
The F-86A was fitted with a T-4E-1 ejection seat, with a manually jettisoned canopy, plus a self-destruct charge to keep it from falling into enemy hands. The F-86A also had a stores pylon under each wing that could each carry a 782 liter (206.5 US gallons) drop tank or a 450 kilogram (1,000 pound) bomb.
Four zero-length stub rocket launchers could be installed under each wing, with each launcher carrying two 12.7 centimeters (5 inches) “High Velocity Air Rockets (HVARs)” for a total of 16 rockets.
Unfortunately, without the drop tanks, the combat radius fell from about 530 kilometers (330 miles) to 80 kilometers (50 miles). In effect, the only armament of the F-86A was its machine guns, and so in the beginning it was not very useful for close support.
The first production model was initially designated the P-86A, but became the legendary F-86A in June 1948. When the new fighter entered US Air Force service in 1949 it gained the name, the “Sabre”.
Its success led to an extended production run of over 7,800 aircraft between 1946 and 1956, in the
United States, Japan and Italy. The upgraded Canadair Sabre added another 1,815 airframes, while the CAC CA-27 Avon Sabre saw a production run of 112. It was by far the most-produced Western jet fighter, with total production of all variants at 9,860 units.

Rank 5 – Messerschmidt ME109 Year 1937
The company was renamed Messerschmitt AG in July 1938 when Erhard Milch finally allowed Willy Messerschmitt to acquire the company; from then on, all Messerschmitt aircraft were to carry the “Me” designation except those already assigned a Bf prefix.
Perhaps not the best performer of the war, even its pilots would admit that it was not the safest or most comfortable plane to fly. But its combat record, from beginning to end, was monumental, and it was the weapon of choice for the greatest fighter pilots in history.
A total of 33,984 units were produced up to April 1945. Accounting for 47% of all German aircraft production, as well as 57% of all German fighter types produced.
The ME 109 became the backbone of the Luftwaffe fighter force in World War II, although it began to be partially replaced by the Focke-Wulf Fw 190 from 1941.
The ME/Bf 109 was the most successful fighter of World War II, shooting down more aircraft than any of its contemporaries. It was flown by the three top-scoring fighter aces of World War II: Erich Hartmann, the top scoring fighter pilot of all time with 352 victories, Gerhard Barkhorn with 301 victories, and Günther Rall with 275 victories. All of them flew with Jagdgeschwader 52, a unit which exclusively flew the Bf 109 and was credited with over 10,000 victories.
Originally conceived as an interceptor, it was later developed to fulfill multiple tasks, serving as bomber escort, fighter bomber, day-, night- all-weather fighter, bomber destroyer, ground-attack aircraft, and as reconnaissance aircraft.
The ME 109, including such features as an all-metal monocoque construction, a closed canopy, and retractable landing gear, was one of the first true modern fighters of the era.
Although the Bf 109 had weaknesses, including short range and challenging take off and landing characteristics, it stayed competitive with Allied fighter aircraft until the end of the war.

Rank 4 – F 18 Super Hornet Year 1983
The Super Hornet was first ordered by the U.S. Navy in 1992. The Super Hornet first flew on November 29, 1995 and initial production on the F/A-18E/F began in 1995. Flight testing started in 1996 with the F/A-18E/F’s first carrier landing in 1997. It later entered service with the United States Navy in 1999, replacing the F-14 Tomcat.
Sharing some similarities as previous Hornet variants, the Navy retained the F/A-18 designation to help sell the program to Congress as a low-risk “derivative”; however the Super Hornet is largely a new aircraft.
Design features that were kept included the avionics, ejection seats, radar, armament, mission computer software, and maintenance/operating procedures.
The F/A-18E/F aircraft are 4.2 feet longer than earlier Hornets, have a 25% larger wing area, and carry 33% more internal fuel which will effectively increase mission range by 41% and endurance by 50%.
The Super Hornet also incorporates two additional weapon stations. This allows for increased payload flexibility by mixing and matching air-to-air and/or air-to-ground ordnance. The aircraft can also carry the complete complement of “smart” weapons, including the newest joint weapons such as JDAM and JSOW.
The Super Hornet can carry approximately 17,750 pounds (8,032 kg) of external load on eleven stations. It has an all-weather air-to-air radar and a control system for accurate delivery of conventional or guided weapons.
There are two wing tip stations, four inboard wing stations for fuel tanks or air-to-ground weapons, two nacelle fuselage stations for Sparrows or sensor pods, and one centerline station for fuel or air-to-ground weapons. An internal 20 mm M61A1 Vulcan cannon is mounted in the nose.
Survivability is an important feature of the Super Hornet design. The US Navy took a “balanced approach” to survivability in its design. This means that it does not rely on low-observable technology, such as stealth systems, to the exclusion of other survivability factors. Instead, its design incorporates a combination of stealth, advanced electronic-warfare capabilities, reduced ballistic vulnerability, the use of standoff weapons, and innovative tactics that cumulatively and collectively enhance the safety of the fighter and crew.
The Super Hornet, unlike the previous Hornet, can be equipped with an aerial refueling system (ARS) or “buddy store” for the refueling of other aircraft.
In 2003, the Navy identified a flaw in the Super Hornet’s under wing pylons, which could reduce the aircraft’s service life unless repaired. The problem has been corrected on new airplanes and existing airplanes will be repaired starting in 2009.
The versatility of the F-18 Super Hornet has led the aircraft to be used in such missions including; day/night strikes with precision-guided weapons, anti-air warfare, fighter escort, close air support, suppression of enemy air defense, maritime strikes, reconnaissance, forward air control (Airborne) (FAC(A)), air-to-air refueling as well as leaflet drops with payload delivery unit 5 (PDU-5) containers.

Rank 3 – MIG 21 (F-13 / Fishbed C) Year 1959
The MiG-21F, a continuation of Soviet jet fighters MiG-15, 17 and 19, is a short-range day fighter-interceptor and the first major production version of the popular MiG-21 series. It is one of around 15 versions of this aircraft that have served in the air arms of many nations around the world.
The E-5 prototype of the MiG-21 was first flown in 1955 and made its first public appearance during the Soviet Aviation Day display at Moscow’s Tushino Airport in June 1956.
When the MiG-21 was first introduced, it exhibited several flaws. Its early version air-to-air missiles, the Vympel K-13 (AA-2 ‘Atoll’), were not successful in combat, and its gyro gunsight was easily thrown off in high-speed maneuvers. Once these problems had been revised, the MiG-21 became a formidable fighter aircraft.
Employing a delta configuration, the MiG-21 was the first successful Soviet aircraft combining fighter and interceptor characteristics in a single aircraft. It was a lightweight fighter, achieving Mach 2 with a relatively low-powered afterburning turbojet.
The fighter holds a number of aviation records, including the most produced supersonic jet aircraft in aviation history, the most produced combat aircraft since World War II, and the longest production run of a combat aircraft.
Its Mach 2 capability exceeds the top speed of many later modern fighter types. It has been estimated that more than 10,000 MiG-21s were built. More than 50 countries of the world have flown the MiG-21.

Rank 2 – Supermarine Spitfire Year 1938
The Spitfire was originally designed by R. J. Mitchell, chief designer at the Supermarine Aviation Works, a subsidiary of Vickers-Armstrongs. He continued to refine the design until his death from cancer in 1937, whereupon his colleague Joseph Smith became chief designer.
R. J. Mitchell’s 1931 design to meet Air Ministry specification F7/30 for a new and modern fighter capable of 250 mph, the Supermarine Type 224, resulted in an open-cockpit monoplane with bulky gull-wings and a large fixed, spatted undercarriage powered by the 600 horsepower evaporative-cooled Rolls-Royce Goshawk engine.
Based on Reginald Mitchell’s aesthetically pleasing F.7/30 design, the Spitfire was a complex design for its day, with a light alloy monocoque fuselage and a single spar wing, with stressed-skin covering and fabric-covered control surfaces.
The first prototypes employed a DeHavilland two-blade wooden fixed-pitch propeller. After initial testing, this was replaced by a DeHavilland three-blade, two position propeller, and later in 1940, a DeHavilland three-blade constant-speed propeller was substituted.
Production Spitfires had a fixed tail wheel, and triple ejector exhaust manifolds. The PV.12 engine which became the X80 HP Rolls-Royce Merlin II and later the Merlin III engine were installed.
Standard armament in what was known as the “A wing” was eight 0.303-in. Browning machine-guns with 300 rounds of ammunition. The speed of the Spitfire I was marginally higher than that of its principal opponent the Luftwaffe’s Messerschmitt Bf 109E, and it was infinitely more maneuverable than the German fighter, although the Bf 109E could out climb and out dive the British fighter, and its shell-firing cannon had a longer range than the Spitfire’s machine-guns.
In an effort to develop the Spitfire further, two principal modifications were made, these included the introduction of a pressurized cabin and the use of an engine suitably rated for higher altitude. These changes were incorporated in the Spitfire Mark IV.
Deliveries of production Spitfire I’s began in June 1938; just over two years after ‘Mutt’ summers flew the prototype at Southampton on the 5th of March, 1936.
In the two years preceding production, Supermarine laid out their Wollaston factory for large-scale production, and organized one of the largest subcontract schemes ever envisioned in Britain.
Its elliptical wing had a thin cross-section, allowing a higher top speed than the Hawker Hurricane and many other contemporary designs.
Much loved by its pilots, the Spitfire saw service throughout the whole of the Second World War, continuing to serve as a front line fighter for several air forces well into the 1950s.
The Spitfire will always be compared to its main adversary, the Messerschmitt Bf 109: both were among the finest fighters of their day and followed similar design philosophies of marrying a small, streamlined airframe to a powerful liquid-cooled inline engine.

Rank 1 – P51 Mustang Year 1941
The Mustang was a fast, well-made, and highly durable aircraft; it was also very economical to produce.
The P-51s first flight took place 26th October 1940. It was powered by the Packard V-1650-7, a two-stage two-speed supercharged 12-cylinder Packard-built version of the legendary Rolls-Royce Merlin engine, and was armed with six .50 caliber (12.7 mm) Browning M2/AN machine guns, a version of the Browning adapted for use in combat aircraft.
The first production contract was awarded by the British for 320 NA-73 fighters, named Mustang I by the British and designated the XP-51 by the US Air Force.
The Mustang I made its debut in combat on 10 May 1942 for the British RAF. With its long range and excellent low-level performance, it was employed for tactical reconnaissance and ground-attack duties over the English Channel.
The original aircraft had limitations when flying over 15,000 ft and did not become a valued fighter until modifications were made.
To enhance altitude capabilities, the British tested the Rolls-Royce Merlin engine in the P-51 airframe.
Four airframes were adapted in England to take the Merlin engine. These four planes known as Mustang Xs had deep intakes below the engine for carburetor air. The results of the British tests were passed on to North American.
At the same time on the other side of the Atlantic, North American had undertaken a similar conversion project and was building two Packard Merlin-powered Mustangs.
These improvements increase speed by 51 mph. The newly fitted Packard-built Merlin V-1650-7 was capable of delivering 1,695 hp which provided a speed of 437 mph at 25,000 feet.
The airframes were strengthened to accommodate the extra power, the ventral radiator was deepened, and the carburetor intake was moved from above the nose to below, to accommodate the Merlin updraft induction system.
The P-51 became one of the aviation world’s elite. The total number of 14,819 Mustangs of all types were built for the Army. American Mustangs destroyed 4,950 enemy aircraft in Europe to make them the highest scoring US fighter in the theater.
They were used as dive-bombers, bomber escorts, ground-attackers, interceptors, for photo-recon missions, trainers, transports (with a jump-seat), and after the war, high performance racers.
