"For want of a nail . . ."


Recommended Posts

In 1946, the Air Ministry and the Admiralty issued the specifications F.44/46 and N.40/46 for a twin-engined, two-seat long range fighter.
De Havilland responded with their de Havilland 110, and Gloster with their GA.5. The R
AF expressed an interest in the de Havilland project, and a number of prototypes were ordered. The Navy rejected both proposals, and opted for an enhanced Sea Venom. Gloster lobbied successfully, and prototypes of their tailed delta design were also ordered, even though the de Havilland design seemed more promising.


By 1951, the dH 110 was well into its test programme, regularly flying supersonically, while the GA.5 (Javelin) was plagued by flutter and other aerodynamic problems.


Then, at the Farnborough Air Show on 6th September 1952, the dH 110 prototype WG236 broke up in transonic flight, with the engines and forward fuselage ploughing into the crowd, killing the crew and 29 spectators, and severely injuring more than 60 others. The RAF switched its attentions to the Javelin, and four years later, the Navy accepted a navalised dH 110 as the Sea Vixen.


But what if . . .


If John Derry had flown his display without incident, the Air Ministry’s choice may well have alighted on the de Havilland design. It was aerodynamically superior to the Javelin, which was thick-winged and draggy, with inadequate pitch control and engines buried so deeply in the fuselage that power losses in the intakes and exhausts emasculated them. The Vixen, on the other hand, was aerodynamically cleaner, with a relatively thin wing, and offered potential advantages in range, speed and acceleration. It was also cleared for use of the Firestreak and Red Top Missile much earlier than was the Javelin.
If the RAF had gone with the Vixen, by 1970 they might have ended up with this:


de Havilland Vixen F(AW).5, 11 Sqn, RAF, Geilenkirchen, 1970.

different .......but actually well done, thanks for sharing. In conversation with a Vixen "looker" a couple of years ago, he blamed his life in the "coal hole" on the  de Havilland team in the original design stages still flushed with success from that side by side set up from the mossie, he reckons a decent hood built around the tube would have sufficed - with your "what if" , I wonder if the crabs would have re-designed the cockpit to look more like the Javelin??

 

actually, looking again, that really is a smart build you have there...
