Having shown you the Avro 774 I couldn't resist doing the 776!
The basic anti-submarine and maritime patrol Avro 776 based on the de Havilland Trident airliner but powered by three Rolls-Royce Medway engines and a new bigger-span wing. Note, the source I have shows the fuselage to be essentially that of the 774 so would be completely new. In Derek Wood's project cancelled it is shown as basically a Trident fuselage (totally different window layout too) with new wings and the Medway engines. The dorsal intake is slightly different too. I think this is probably the 1961 submission and so my drawing, with the 774 fuselage would probably be the original 1960. I'm guessing at some point it was felt keeping the Trident nose would save some money!
The proposed Skybolt-carrier version of the Avro 776. Again Wood shows a Trident nose but I've kept the 774 fuselage and removed the glass nose. The 776 lost out to the VC-10 for the airborne patrol role because the VC-10 had greater range and payload and could carry eight Skybolts, rather than the four of 776. Interestingly, the bomb bay seems to be retained too...
