Yes, the British Aerospace Industry was a match for any on the planet until the ”White Paper” that said manned military aircraft were obsolete and missiles were the way of the future. The EE Lightning had ”supercruise” before anybody else even thought of the concept. The incredible TSR.2 was cancelled, and the Harrier would be the end of the line for pure British warplanes. All that followed would be international partnerships Jaguar, Tornado, Typhoon, Harriers beyond the GR.3...
Just like the “White Paper” that came along later which said aircraft carriers were obsolete and no longer needed. Had Argentina invaded the Falkland Islands in April 1983 instead of 1982, many ships (especially Hermès) that were crucial to the near run success of that operation would not have been there.
Oh yes, I would put the Hawker Hunter on par with the F-86. Although a few years after the Sabre (1951 vs. 1947 first flights) it was a design with more potential and performance.
