Grumman F4F Wildcat

The Grumman F4F Wildcat was an American carrier-based fighter aircraft that began service with both the United States Navy and the British Royal Navy in 1940. Although first used in combat by the British in Europe, the Wildcat was the only United States Navy or Marine fighter in World War II 1941–42 in the Pacific Theater besides the brief appearance of the F2A Buffalo. With a top speed of 318 mph (512 km/h), the Wildcat was outperformed by the more nimble 331 mph (533 km/h) Mitsubishi Zero, but its ruggedness and tactics such as the Thach Weave resulted in an air combat kill-to-loss ratio of 5.9:1 in 1942 and 6.9:1 for the entire war.

Lessons learned from the Wildcat were applied to the faster F6F Hellcat which could outperform the Zero on its own terms. The Wildcat continued to be built throughout the remainder of the war to serve on escort carriers, where larger and heavier fighters could not be used.

Grumman fighter development started with the two-seat Grumman FF biplane. The FF was the first US naval fighter with landing gear which retracted, but left the tires visibly exposed although flush on either forward fuselage side. The F2F and F3F were single-seat biplane fighters which established the general outlines and landing gear configuration of what would become the Wildcat. In 1935, while the F3F was still undergoing flight testing, Grumman started work on its next fighter biplane, the G-16. The Navy favoured the monoplane Brewster F2A-1, ordering development early in 1936, but placed an order for Grumman's G-16, with the navy designation XF4F-1 as a backup in case the Brewster monoplane failed.

It was clear to Grumman, however, that the XF4F-1 would be inferior to the Brewster monoplane, so Grumman abandoned the XF4F-1, designing a new monoplane fighter, the XF4F-2. The Wildcat would retain the fuselage-mounted, hand-cranked landing gear with its relatively narrow track. In service, this would lead to distressingly common landing accidents when the landing gear did not fully lock into place. This unusual main landing gear design was originally designed by Leroy Grumman for Grover Loening in the 1920s and used earlier on all of Grumman's fighter biplanes (from the FF-1 through the F3F) of the 1930s and on the J2F Duck amphibious flying boat.




Even this new monoplane fell short against the Buffalo. The XF4F-2 was marginally faster, but the Buffalo was otherwise judged superior and was chosen for production. Grumman's prototype was then rebuilt as the XF4F-3 with new wings and tail and a supercharged version of the Pratt & Whitney R-1830 "Twin Wasp" radial engine. Testing of the XF4F-3 led to an order for F4F-3 production models, the first of which was completed in February 1940. France also ordered the type, powered by Wright R-1820 "Cyclone 9" radial engines, but France fell before they could be delivered and they ultimately went to the British Royal Navy, which named them "Martlets", using their own naming system early in World War II. Both the British aircraft and the US Navy's F4F-3, with an armament of four .50 in (12.7 mm) Browning machine guns, joined active units in 1940.

Although the Buffalo was the Navy's first monoplane fighter, it would prove disappointing in combat and be withdrawn early in World War II. The name "Wildcat" was officially adopted on 1 October 1941. The Wildcat's successor was the F6F Hellcat, a complete redesign which dropped Grumman's distinctive, exposed main landing gear arrangement. First flying in 1942, the Hellcat outclassed the Zero almost completely, surprising many Japanese pilots at first that often mistook the outlines for the older, slower Wildcat. The Navy would also introduce the F4U Corsair first to land and later to shipboard use which could match the top speed of the fastest land-based planes.

Hawker Hurricane

The Hawker Hurricane is a British single-seat fighter aircraft that was designed and predominantly built by Hawker Aircraft Ltd. for the Royal Air Force (RAF). Although largely overshadowed by the Supermarine Spitfire, the aircraft became renowned during the Battle of Britain, accounting for 60% of the RAF's air victories in the battle, and served in all the major theatres of the Second World War.

The 1930s design evolved through several versions and adaptations, resulting in a series of aircraft which acted as interceptor-fighters, fighter-bombers (also called "Hurribombers"), and ground support aircraft. Further versions known as the Sea Hurricane had modifications which enabled operation from ships. Some were converted as catapult-launched convoy escorts, known as "Hurricats". More than 14,000 Hurricanes were built by the end of 1944 (including about 1,200 converted to Sea Hurricanes and some 1,400 built in Canada by the Canada Car and Foundry).

The maiden flight of the first production aircraft, powered by a Merlin II engine, took place on 12 October 1937. The first four aircraft to enter service with the RAF joined No. 111 Squadron RAF at RAF Northolt the following December. By the outbreak of the Second World War, nearly 500 Hurricanes had been produced, and had equipped 18 squadrons




During the eleven days of fighting in France and over Dunkirk on 10—21 May 1940, Hurricane pilots claimed 499 kills and 123 probables. Contemporary German records, examined post-war, attribute 299 Luftwaffe aircraft destroyed and 65 seriously damaged by RAF fighters.

The Battle of Britain officially lasted from 10 July until 31 October 1940, but the heaviest fighting took place between 8 August and 21 September. Both the Supermarine Spitfire and the Hurricane are renowned for their part in defending Britain against the Luftwaffe — generally the Spitfire would intercept the German fighters, leaving Hurricanes to concentrate on the bombers, but despite the undoubted abilities of the "thoroughbred" Spitfire, it was the "workhorse" Hurricane that scored the highest number of RAF victories during this period, accounting for 1,593 of the 2,739 claimed.

Curtiss P-40 Warhawk

The Curtiss P-40 Warhawk ( bears the name Tomahawk and Kittyhawk for Allied squadrons ) was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including those of most Allied powers during World War II, and remained in front line service until the end of the war. The P-40 design was a modification of the previous Curtiss P-36. By November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facility at Buffalo, New York.

Restorated P-40 Warhawk

The P-40 had good agility, especially at high speed and medium to low altitude. It was one of the tightest-turning monoplane fighters of the war,although at lower speeds it could not out-turn the extremely manoeuvrable Japanese fighters such as the Mitsubishi A6M Zero and Nakajima Ki-43 "Oscar".

P-40 Warhawk on formation

According to some sources the P-40 initially proved quite effective against Axis aircraft and contributed to a slight shift of momentum in the Allied favor. The gradual replacement of Hurricanes by the Tomahawks and Kittyhawks led to the Luftwaffe accelerating retirement of the Bf 109E and introducing the newer Bf 109F; these were to be flown by the veteran pilots of elite Luftwaffe units, such as Jagdgeschwader 27 (JG27), in North Africa.

P-40 Kittyhawk with RAF insignia

The P-40 was generally considered roughly equal or slightly superior to the Bf 109 at low altitude, but inferior at high altitude, particularly against the Bf 109F. Most air combat in North Africa took place well below 16,000 ft (4,900 m), thus negating much of the Bf 109's superiority. The P-40 usually had an edge over Bf 109 in horizontal maneuverability, dive speed and structural strength, was roughly equal in firepower, but was slightly inferior in speed and outclassed in rate of climb and operational ceiling.

The P-40 was generally superior to early Italian fighter types, such as the Fiat G.50 and the Macchi C.200. Its performance against the Macchi C.202 Folgore elicited varying opinions. Some observers consider the Macchi C.202 superior. Clive Caldwell, who scored victories against them in his P-40, felt that the Folgore would have been superior to both the P-40 and the Bf 109 except that its armament of only two or four machine guns was inadequate. Other observers considered the two equally matched, or favored the Folgore in aerobatic performance, such as turning radius. Boyne wrote that over Africa, the P-40 and the Folgore were "equivalent".




P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, during June 1941. The Royal Air Force's No. 112 Squadron was among the first to operate Tomahawks, in North Africa, and the unit was the first to feature the "shark mouth" logo, copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. Inspired by 112 Squadron's usage of them in North Africa, and by the Luftwaffe's even earlier use of it, both via Allied wartime newspaper and magazine article images, the "shark mouth" logo's usage on the sides of the P-40's nose was most famously used on those used by the Flying Tigers in China.

In theatres where high altitude performance was less important, the P-40 proved an effective fighter. Although it gained a post-war reputation as a mediocre design, suitable only for close air support, more recent research including scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 offered the additional advantage of low cost, which kept it in production as a ground attack fighter long after it was obsolete in air superiority.

Supermarine Spitfire

The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries throughout the Second World War. The Spitfire continued to be used into the 1950s both as a front line fighter and in secondary roles. It was produced in greater numbers than any other British aircraft and was the only Allied fighter in production throughout the war.

The Spitfire was designed as a short-range high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works (since 1928 a subsidiary of Vickers-Armstrongs). Mitchell continued to refine the design until his death from cancer in 1937, whereupon his colleague Joseph Smith became chief designer. The Spitfire's elliptical wing had a thin cross-section, allowing a higher top speed than the Hawker Hurricane and several contemporary fighters. Speed was seen as essential to carry out the mission of home defence against enemy bombers.

During the Battle of Britain there was a public perception that the Spitfire was the RAF fighter of the battle, in fact the more numerous Hurricane actually shouldered a greater proportion of the burden against the Luftwaffe.




After the Battle of Britain, the Spitfire became the backbone of RAF Fighter Command and saw action in the European, Mediterranean, Pacific and the South-East Asian theatres. Much loved by its pilots, the Spitfire served in several roles, including interceptor, photo-reconnaissance, fighter-bomber, carrier-based fighter, and trainer. It was built in many different variants, using several wing configurations. Although the original airframe was designed to be powered by a Rolls-Royce Merlin engine producing 1,030hp (768 kW), it was adaptable enough to use increasingly more powerful Merlin and the later Rolls-Royce Griffon engines; the latter was eventually able to produce 2,035 hp (1,520 kW).

Spitfire Mk Is K9789 entered service with 19 Squadron at RAF Duxford on 4 August 1938. The Spitfire achieved legendary status during the Battle of Britain, a reputation aided by the famous "Spitfire Fund" organised and run by Lord Beaverbrook the Minister of Aircraft Production. Although the key aim of Fighter Command was to stop the Luftwaffe's bombers, in practice the tactic was to use Spitfires to counter German escort fighters, particularly the Bf 109s, while the Hurricane squadrons attacked the bombers.

Chance Vought F4U Corsair

This Chance Vought F4U Corsair has been serving U.S. Navy and U.S. Marines during World War II, It became the most capable carrier-based fighter-bomber of World War II.

Restorated F4U Corsair

The F4U incorporated the largest engine available at the time, the 2,000 hp (1,500 kW) 18-cylinder Pratt & Whitney R-2800 Double Wasp radial. To extract as much power as possible, a relatively large, 13 feet 4 inches (4.06 m) Hamilton Standard Hydromatic three-blade propeller was used. To accommodate a folding wing, the designers considered retracting the main landing gear rearward, but for the chord of wing selected, it was difficult to fit undercarriage struts long enough to provide sufficient clearance for the large propeller. Their solution was an inverted gull wing, a similar layout to the one used by Germany's Junkers Ju 87 dive bomber, considerably shortening the length of the main gear legs. The anhedral of the wing's center-section also permitted the wing and fuselage to meet at the optimum angle for minimizing drag, without the need for wing root fairings. Offsetting these benefits, the bent wing was more difficult to construct and weighed more than a straight one.

Corsairs were flown by the famous "Black Sheep" Squadron (VMF-214, led by Marine Major Gregory "Pappy" Boyington) (VMF is Marine Attack Squadron, an aviation unit of USMC) in an area of the Solomon Islands called "The Slot". Boyington was credited with 22 kills in F4Us (of 28 total, including six in an AVG P-40). Other noted Corsair pilots of the period included VMF-124's Kenneth Walsh, James E. Swett, and Archie Donohue, VMF-215's Robert M. Hanson and Don Aldrich, and VF-17's Tommy Blackburn, Roger Hedrick, and Ira Kepford. Nightfighter versions equipped Navy and Marine units afloat and ashore.

At war's end, Corsairs were ashore on Okinawa, combating the Kamikaze, and also were flying from fleet and escort carriers. VMF-312, VMF-323, VMF-224, and a handful of others met with success in the Battle of Okinawa.

F4U Corsair on formation

Corsairs also served well as fighter bombers in the Central Pacific and the Philippines. By spring 1944, Marine pilots were beginning to exploit the type's considerable capabilities in the close-support role during amphibious landings. Charles Lindbergh flew Corsairs with the Marines as a civilian technical advisor for United Aircraft Corporation in order to determine how best to increase the Corsair's payload and range in the attack role and to help evaluate future viability of single- versus twin-engine fighter design for Vought. Lindbergh managed to get the F4U into the air with 4,000 pounds (1,800 kg) of bombs, with a 2,000 pounds (910 kg) bomb on the centerline and a 1,000 pounds (450 kg) bomb under each wing. In the course of such experiments, he performed strikes on Japanese positions during the battle for the Marshall Islands.

By the beginning of 1945, the Corsair was a full-blown "mudfighter", performing strikes with high-explosive bombs, napalm tanks, and HVARs. She proved surprisingly versatile, able to operate everything from Bat glide bombs (without sacrificing a load of 2.75 in/70 mm rockets) to 11.75 in (300 mm) Tiny Tim rockets. The aircraft was a prominent participant in the fighting for the Palaus, Iwo Jima and Okinawa.

Today this legendary "Whistling Death" fighters are mostly used for airshows, flybys, film and also for a warbird aerobatic airshow routine.

North American P-51 Mustang

The North American Aviation P-51 Mustang was an American long-range single-seat World War II fighter aircraft. Designed and built in just 117 days, the Mustang first flew in Royal Air Force (RAF) service as a fighter-bomber and reconnaissance aircraft before conversion to a bomber escort, employed in raids over Germany, helping ensure Allied air superiority from early 1944.[2] The P-51 was in service with Allied air forces in Europe and also saw limited service against the Japanese in the Pacific War. At the start of Korean War the Mustang was the United Nations' main fighter but the role was quickly shouldered by jet fighters, including the F-86, after which the Mustang became a specialised ground-attack fighter-bomber. In spite of being superseded by jet fighters the Mustang remained in service with some air forces until the early 1980s.

As well as being economical to produce, the Mustang was a fast, well-made, and highly durable aircraft. The definitive version, the P-51D, was powered by the Packard V-1650, a two-stage two-speed supercharged version of the legendary Rolls-Royce Merlin engine, and was armed with six .50 caliber (12.7 mm) M2 Browning machine guns.
