That out of date design could out fly any aircraft today. Airspeed was +2x mach and the alt was over 80,000 ft. That was then. With todays technoligy who knows.
I'm a Canadian. I was around when the Arrow flew. The only reason it was scrapped was because of the US Government.
Im sorry but that is a highly generalized statement. Top speed yes is faster than the F-35 but that is because the design requirements of the F-35 did NOT state Mach 2 capability. Designing a plane for that regime is extremely demanding not to mention that it has been realized that there is no useful purpose for a fighter to go Mach 2+ today. You cannot maneuver at that speed because your turn rate is the size of Texas and you burn a huge amount of fuel getting there. However, there is no way a CF-105 could out fly a F-16, Mig-29, Su-27, F/A-18, Mirage 2000, etc...Im not even going to mention the 4.5 and 5gen fighters! The CF-105 was NOT designed for manueverability and it shows. It was an extremely large fighter which would have been a giant turkey in a dogfight. Its control system too was not as advanced as some say it was. The F-106/F-102 family had a sophisticated system and even the F-94s had the ability to be remotely controlled by GCI.
Now about the US gov't involvement. I would say the cancellation had more to do with the fact that the Soviets had infiltrated the CF-105 program and was siphoning data and specs from it to the Kremlin. In other words, development of the CF-105 at the time was not only advancing Canadian/Western fighter design but it also was advancing Soviet design technology as well. The US gov't involvement stems more from the REPLACEMENT of the canceled CF-105 program via the CF-101 Voodoo.
I should mention on the topic of speed that there is a wide variety of aircraft from the CF-105's era that were faster than most fighters today...but again, that stems from design requirements. Back then it was all about intercepting large formations of large bombers. Today it is about multi-role capability, efficiency, low-observability, and maneuvering capability, and serviceability. On almost all accounts the CF-105 is inferior to modern fighters. But again, that should be expected, the design is 60years old after all and is done around a 60 year old mission that does not exist any more.
In short this proposal is completely useless except say for giving the CF-105 a shot at military service for those die-hard fans of it. (which Im guessing you are)
