The classic lines of the Hornet family are well illustrated in this fine shot of the Sea Hornet PR22 prototype TT187

The DH.103 Hornet was designed as a private venture lightweight twin-engined fighter, optimised for use in the war against Japan. Specification F.12/43 was written around the type which first flew (RR915) on 28 July 1944. In design it resembled a scaled down Mosquito and like its forebear it was remarkably fast; the prototype exceeded 485 mph. The Hornet equipped Fighter Command day fighter units in the UK and later was used with success as a strike fighter in Malaya. It was the fastest piston-enginned fighter in Royal Air Force service.

F Mark 1 The first Hornet was armed with four 20mm cannon and it entered service with 64 Sqn in May 1946. Like all variants it was powered by the Merlin 130/131 driving handed propellor units. First production machine was PX210 which flew on 1 March 1945 and the Mark 1 served only in the UK, lacking the range of later variants.

PR Mark 2 The Mark 2 was designed as an unarmed reconnaissance vehicle for use in the Far East. An early production F Mk 1 (PX216) served as the prototype and five were built before the end of the war resulted in the decision to abandon the type.

F Mark 3 The main fighter variant was provided with increased internal tankage (from 360 to 540 gals) plus a further 400 gals in underwing tanks. To improve lateral stability a dorsal fillet was introduced and provision was made for two 1,000lb bombs or eight 60lb RPs under the wings. It entered service with 19 Sqn in March 1948 and when replaced by jet types in the UK this variant, together with the FR4, served in Malaya and Hong Kong.

FR Mark 4 The Mark 4 was the last of the Hornets and it was used exclusively in the Far East. It was basically an F Mk 3 equipped for photo-reconnaissance with an F.52 camera displacing 21 gals of fuel. Some were built on the production line while others were F Mk 3 conversions.

The DH103 Sea Hornet was initially produced to specification N.5/44 calling for a long-range fighter for use against the Japanese. The first prototype was PX212, a converted Hornet I which flew on 19 April 1945. The Sea Hornet was the first twin-engined type to operate from British carriers, but it entered service too late to play any part in the Second World War.

F Mark 20 The Mk 20 was similar to the RAF's F Mk 3 but with folding wings and a fuselage camera window. The engines were the Merlin 130/131, which were handed, and armament comprised four 20mm cannon, and eight 60lb RPs or two 1,000lb bombs. Only one front-line unit was fully equipped with the variant.

NF Mark 21 The night fighter was built to specification N.21/45 and fitted with an ASH radar in a thimble radome and a radar operator's cockpit in the rear fuselage. The tailplane span was increased to improve stability and the engines were the Merlin 134/135. The NF Mk 21 served with only one front-line unit, and that for only two years from completion of working-up.

PR Mark 22 For photo-reconnaissance the armament of the F Mk 20 was removed and replaced with two F.52 cameras (day photography) or a K.19B camera for night work.
