A decade after World War Two, Canada built a jet which pushed technology to its limits. But its demise showed why smaller nations found it difficult to compete in the Jet Age.
The 5U never had a chance to prove (or disprove) itself and the F-22 tooling was destroyed, all in the name of politics.
My understanding is that the Arrow was a gathering of all the best tech of the time, right up until Sputnik launched ad made it immediately appear obsolete. Who needs an expensive interceptor when the bad guys look like they are going to be skipping the bombers and lobbing unstoppable bombs from space?Though the 1957 Arrow was an amazing design, it was not that far ahead of the curve.
The B-35/B-49 was pretty much "disappeared" back in the day. Awful story...to this day the it has not been able to be told in full. Aircraft and tooling destroyed, documentation destroyed, name it. All so Stuart Symington's pals at Convair can have their B-36 contract.That is a sadder story , than the cancellation of the Northrop B-35 and B-49 program!
The problem was that restarting F-22 production would have been absurdly expensive. Huge initial costs and several years to get everything back up and running, plus a lot of engineering and development time to replace and qualify equipment that is no longer available because the suppliers went out of business, the components aren’t made any more, etc. And that doesn’t even include having to re-learn all the processes and institutional knowledge that goes away when programs shut down and the people involved move on to other projects, retire, die off, etc.The F-22 tooling and process documentation still exists in full at the Sierra Army Depot in California. There were studies done to restart Raptor production but apparently the USAF went in a different direction and has created a new fighter in secret.
Politics certainly plays a huge role in these endeavors.
