Hi people, Recently I was reading David K Brown's work on British naval design ( Nelson to Vanguard: Warship Design and Development 1923-45), and here this description about what he referred to as "B bomb" caught my attention. Unfortunately I could not find much information about it...

Hi everybody, I often read that Curtiss-Wright Aviation did not do enough research work during the Second World War to be able to survive its aeronautical branch and face the new markets after the Second World War. It is considered that its production and improvement work on the P-40 (we can...

Ever since the first Zeppelin raids in World War 1 the vulnerability of the civilian population of the UK to attack from the air has been a major factor in shaping our armed forces.

As any deeply invested Spitfire fan knows, the intended major developments never eventuated and the history of the Spitfire was one of interim variants that did very well. The dead ends are as follows: SPITFIRE III: Merlin 20 development with four cannon and major airframe revisions; abandoned...

Hi everyone, I tend to be quite interested in discussing the details of a scenario where the Entente holds the front near the Franco-Belgian border in 1940 (mostly in other forums). I was now wondering what the impacts would be for the RAF. Obviously we may see fewer American aircrafts in...
