The SE5 was .....contestibly considered by many to be the best fighterplane to be developed during the first world war not only was it fast and manoeverable it was reliable and strongly constructed as well. Predictably the SE5 was very popular with it's pilots and a welcome break for their long suffering ground crews when it was introduced. This revolutionary aircraft was not welcomed by the general staff because it had been initially designed and produced by a government department the SE5 and this was the reason why it was dropped by the RAF almost immediately after the first world war ended.... The last working examples of these marvellous machines were lovingly maintained by the R.A.A.F in Australia they were in service all the way into the early 1930s.
I suppose on reflectio with relation to this event it becomes apparent that the British government had to keep an aircraft industry in being to maintain an embryo aircraft industry for the future it took ten years for the post first world war aircraft industry was able to produce an airplane superior to the original wartime SE5
You could say the SE5 was the 1920s equivalent of the TSR2 which was arbitrarily suspended because it's perfomance completely eclipsed the much hyped American F111 being promoted by the Amnericans. The F111 was a prematurely contrived machine built on a raft of technologically compromised concepts such as the wallis swing wing concept. The F111 finally became a credible military aircraft 25 years after it's original launch due to a continuous programme of intensive expensive and ultimately futile development to realise it's potential only when it was already becoming obsolescent...
After knowing of the history of the SE5 how could the Aussies still buy the flawed F111 I suppose it was because the lesson was ignored because they never had to worry about having to keep a fledgling aircraft industry in being especially when the design teams were off form? I gather that the Australian military are now increasingly embroiled in such expensive upkeep activities for their air land and naval military forces now.... now they might have some small idea how hard their much derided mother-country worked to keep them safe and secure .
