I'ver seen the specs for the Mark III Arrow and it would have been a heck of an aircraft. The US produced practically nothing to compare until the F14/Phoenix systems.
Out of curiosity sparked by this thread, Canadians made a lot of good stuff that has been forgotten over time.
Even during the Korean war they made the f86, the hurricane and lancaster for ww2, DC3 workhorse etc.
