304 FLIGHT Sea Venom The Sea Venom is the naval counterpart of the R.A.F.'s Venom two-seat night fighter, which was itself a development of the Venom single-seat fighter/bomber. All three types continue in service and the Sea Venom will remain as the standard British naval aeroplane of its class until succeeded by the Sea Vixen. The built-in armament is four 20 mm guns, which are useful not only in the interception role, but when the Venom is employed on ground-attack operations, for which purpose it can carry an additional load of bombs or rocket projectiles. Pilot and observer—the latter operating the radar—are seated side by side in lightweight ejection seats. The latest operational mark is the FAW.22, which has a more powerful version of the de Havilland Ghost turbojet than had earlier models. The Sea Venom is serving also with the Royal Australian Navy. Heron 2 Like its predecessor, the Dove, the Heron has proved adaptable to changing requirements. While airline capacity needs have increased, it has found a ready market in the executive-ownership field. Most of the production today is, in fact, for the business market, and the cachet "airliner in miniature" which has been applied to the Heron neatly sums up its appeil to the executive. More than 100 Herons have now been built, and the Series 2 version in production today differs considerably from the early Heron 1. The original design conception was "utter simplicity"—fixed undercarriage, direct-drive unsupercharged Gipsy engines, no feathering propellers, no hydraulics, and so forth. Because demand dictated (particularly executive demand), the Heron 2 of today is a more refined aircraft, with retractable undercarriage and feathering propellers. Its greatest asset, uncommon in this size of aircraft, lies in its four engines, ensuring lively field performance and high safety standards. Dove 5 and 6 The Dove was Britain's first post-war transport aeroplane, and to have maintained its attractions in a fast-changing market for 12 years is a remarkable achieve- ment. The models in production today—Doves 5 and 6—are little changed from the early Dove, although the market at which the aircraft was originally aimed—the passenger transport market—has radically different requirements today. In the early post-war days the need was for a sophisticated development of small pre-war types like the Dragon Rapide; as traffic grew the airline industry demanded larger-capacity vehicles to carry its traffic economically. This led in 1950 to the Heron (described above); but the Dove readily found its way into other markets. Today production is almost entirely taken up by executive demand, and since this is a class of business which changes its requirements less rapidly than airline transport, the future of the Dove seems assured for some time ahead.
