Lots of replies here against the F-23. But I bet there is not even one from a combat pilot. Are there any combat pilots posting here that would rather dogfight rather than being higher faster and invisible to the enemy. If he or she has that advantage all they have to do is push the button on a missile, and the enemy is gone. An enemy that is gone is a good thing. The pilot gets to come home. THAT is what it is all about.

Also North American produce the Vigilante. Although it was a medium bomber, its design was the prototype of many fighters such as the F-14, F-15, and the MIG 29 and 31. It is apparent that the North American engineers were at the top of the game.

The 40s too. They designed the P-51!!

Not only did cancelling the B-70 set back large supersonic airliners, it set back engine development.

The GE J-93 engines were in the near 30,000 pound class. If the B-70 had not been cancelled Pratt and others would have developed their own engines of that power. How much longer was it before engines that powerful became generally available?

People can argue against it, but that plane on the absolute leading edge of technology absolutely would have advanced general aviation. Sadly it was lost because of dumb political reasons.

It still remains that the leap forward that the B-70 would have generated in aviation was lost. Cancelling it set aviation back decades. Where are the supersonic transports we should have had 30 years ago. Military science and engineering has always led the way. That is why civil aviation got jets.

The fact still remains that there is virtually nothing the B-52 does that the B-70 couldnt do faster and better.

Example————carry cruise missiles to a firing point. Getting those cruise missiles to that drop off point 4 time faster could save American lives or the lives of our allies.

Also doing a little research the bomb carrying capacity, and the range is not that much different between the two aircraft. Remember because of the brilliant compression lift design that the B-70 had, its range was greatly extended.

Lastly higher and faster is better than low an slow. Just ask any pilot. And————there is a 99% chance that sadly the decision to cancel that brilliant design was undoubtably a political one, which everyone knows is a stupid reason.
