de Havilland Hornet — Fighter
Open in interactive gallery →

The de Havilland Hornet was the fastest single-seat piston fighter ever built — a twin-engine long-range fighter de Havilland designed in 1942-1944 to escort Far East bombers and engage Japanese fighters. The Hornet first flew on 28 July 1944 but production deliveries did not begin until April 1945, two months before V-E Day. de Havilland built 383 Hornets and Sea Hornets between 1944 and 1956. The aircraft never engaged Japanese forces but served the Royal Air Force and Royal Navy Fleet Air Arm in Malayan Emergency operations 1948-1955 and as a high-performance carrier-based fighter into the 1950s. Maximum speed: 472 mph — faster than any other single-seat piston fighter ever flown.

The Hornet was a wooden-construction (with light alloy stress members) twin-engine single-seat fighter. Power: two Rolls-Royce Merlin 130/131 series 12-cylinder V-engines (2,030 hp each, opposite-rotation), driving four-bladed propellers. Maximum speed 472 mph at 22,000 ft; range 3,000 miles with drop tanks; service ceiling 38,000 ft. Armament: four 20 mm Hispano Mk V cannons in the lower forward fuselage + 2,000 lb of underwing ordnance (rockets or bombs). The aircraft was effectively a smaller, more-aerodynamic single-seat derivative of the de Havilland Mosquito — same construction philosophy, same Merlin engines, but optimised for fighter rather than multi-role missions.

The Hornet's combat record was modest because of its late-war service entry. RAF Hornets equipped 19 and 41 Squadrons in 1946-1951, primarily training and air-defence sorties. The aircraft did fly anti-bandit missions in the Malayan Emergency 1948-1951 against Communist guerrillas in the Malayan jungles. Royal Navy Sea Hornets entered service in 1947 from carrier decks; the F.20 day-fighter, NF.21 night-fighter, and PR.22 photo-reconnaissance variants flew Royal Navy carrier operations through 1955.

The Hornet was the last single-seat piston fighter built in the U.K. and one of the last single-seat piston fighters in front-line service worldwide; production ended in 1956 with the final Sea Hornets. Royal Navy retirement was 1955, RAF in 1956. About 4 Hornet airframes survive in static-display condition in 2026, including the de Havilland Aircraft Museum's Sea Hornet at Salisbury Hall and the Royal Navy Fleet Air Arm Museum's example at Yeovilton. None airworthy.

For Kids — a shorter, friendlier version

The de Havilland Hornet was the fastest single-seat piston-engine fighter ever built. Its top speed was 472 mph — faster than any other piston fighter that ever flew. The Hornet first flew on 28 July 1944, but it came too late to fight in World War II.

The Hornet was a twin-engine fighter designed to escort British bombers in the Pacific war against Japan. It had two Rolls-Royce Merlin V-12 engines, each with about 2,000 horsepower. The body was made mostly of wood, like the famous de Havilland Mosquito.

About 383 Hornets and Sea Hornets were built between 1944 and 1956. The plane is about as long as a city bus. It carried four 20 mm cannons in the nose and could fly more than 1,400 miles in one trip.

The Hornet never fought Japanese forces because the war ended before the plane reached the Pacific. It later served the Royal Air Force and Fleet Air Arm during the Malayan Emergency from 1948 to 1955. The Sea Hornet flew off British aircraft carriers into the early 1950s.

Kids’ Questions

Why was the Hornet made of wood?

De Havilland was famous for its wooden Mosquito bomber from World War II. Wood was light, strong, and did not need scarce wartime metal. Skilled furniture makers and piano workers helped build wooden planes. The Hornet used the same idea — a wooden body wrapped in light metal sheets — and turned out to be faster than any metal piston fighter ever built.

Why is the Hornet the fastest piston fighter ever?

The Hornet had two of the best piston engines ever made — Rolls-Royce Merlins. The wooden body was very smooth and light, with much less drag than metal planes. Two powerful engines plus a slick light body equalled record-setting speed. No piston fighter since has gone faster, because jet engines took over before anyone tried again.

Frequently Asked Questions

How fast was the de Havilland Hornet?

472 mph at 22,000 ft — the fastest single-seat piston fighter ever flown. Faster than the contemporary North American P-51H Mustang (487 mph but only one prototype, never in service) and the U.S. F8F Bearcat (421 mph). The Hornet's two Merlin 130 engines and clean aerodynamics combined to deliver the absolute peak of piston-fighter performance.

Did the Hornet fight Japanese aircraft?

No — the Hornet entered service in April 1945, just before V-J Day. The aircraft never deployed to the Pacific theatre and never engaged Japanese forces. The aircraft did see combat against Communist guerrillas in the Malayan Emergency 1948-1951.

How is the Hornet related to the Mosquito?

The Hornet is a smaller, single-seat derivative of the de Havilland Mosquito — same wooden construction philosophy, same Rolls-Royce Merlin engines (in 130 series), but with one cockpit instead of two and a smaller airframe optimised for the fighter role. The Mosquito was a multi-role aircraft (bomber, night-fighter, reconnaissance); the Hornet was a pure fighter.

How many Hornets were built?

383 airframes total (RAF + Royal Navy, all variants) between 1944 and 1956. About 215 RAF Hornets + 168 Royal Navy Sea Hornets. Production was at de Havilland's Hatfield, Hertfordshire plant.

Are any Hornets preserved?

Yes — about 4 airframes survive in 2026, including a Sea Hornet F.20 at the de Havilland Aircraft Museum (Salisbury Hall), and a Sea Hornet F.20 at the Royal Navy Fleet Air Arm Museum (Yeovilton). None are currently airworthy.
