Two big prpblems with the design:
1. The engines were underpowered at a claimed 1,350 hp each (and did not deliver that much) for the weight of the aircraft. Now if it had 2,300 hp Griffon 89's with counter rotating props:eek:
There was some talk of adapting the plane to turbojet/jet power, but nothing came of it. (or so I read)
2. There was no threat that called for developing and building it. The Axis just did not have a high alt heavy bomber force in use against the U.S. that needed to be stopped. No need for a thing, don't build it.
