Nope, excellent info. And it makes me glad I was not an air-to-air guy.
The author points out that during the Battle of Britain the Hurricane was just a little bit slower and had a little bit less rate of climb then the versions of Spit and Bf109 than the contemporary versions of the Bf and Spit. IIRC where it did fall off was at higher altitudes where it’s turning radius, among other things degraded. But German bombers formations I believe usually came in at less than 20,000ft. Unlike the Americans over Europe two years later.
Unlike the Bf 109 and Spit, no more significant performance improvements could be wrung out of the Hurricane design, the next generation Hurricane-equivalent being the Hawker Typhoon. Structural problems (the tail would sometimes come off in a dive) delaying the deployment of that aircraft.
Generally overlooked is that the excellent low-altitude flight characteristics of the Hurricane lent itself to ground-attack missions, cannon and bomb-armed Hurricanes performing well in that role in North Africa against Rommel. In fact I think I recall the use of wings with interchangeable armament attachment points was pioneered in the Hurricane Mark II. Likewise, by the summer of ‘44 the Typhoon became the pre-eminent British fighter-bomber.
And hanging thinner Spitfire-type elliptical wings on a Typhoon produced the Hawker Tempest, one of the very best fighters of the war.
What really interests me though is Northern France 41’ -‘42, where the qualitative superiority of both the Bf109F and the FW 190 resulted in the Spitfire getting hammered, for a whole year and a half. This gave rise to a number of Spitfire variants, including a clipped-wing low altitude version that could equal the FW190’s excellent rate of roll.
A puzzle though that the Brits were so far behind in the development of workable drop tanks.
