[XB-49]

then we have to create fighters to shoot the damn thing down.

A fully completed MiG-15 with a new FM could catch up to a 'BUFF' easily. MiG-15: 1100 Km/h (684 Mph), Service Ceiling: 15,545m (51,000ft) B-52D: 893 Km/h (554 Mph at altitude) Service Ceiling: 11,600m (38,000ft). And as for complex avionics, the YB-52 was first flown in 1952 complex avionics would be at a mininun (in the early models) and they aren't as needed as the Heinkel Lerche don't you think. :wink: But then again my knowledge of modelling is limited so I may be wrong. And it is up to you modders to decide whether to spend your time on a B-52 or not. But I'm for a BUFF if possible.
