This is a partial list of the British Air Ministry specifications for aircraft. A specification started from an Operational Requirement, abbreviated "OR", describing what the aircraft would be used for - this in turn led to a specification eg a two engined fighter with 4 machine guns. So for example, OR.40 for a heavy bomber led to Specification B.12/36. Aircraft manufacturers would design and build aircraft which the Ministry then bought for evaluation by the RAF. On very rare occasions, a manufacturer would design and build an aircraft using their own money as a "Private Venture". This would then be offered to the Ministry for evaluation. If the aircraft generated interest in the Ministry or RAF due to performance or some other combination of features then the Ministry might well bring out a specification based on the Private Venture aircraft. The Air Ministry was formerly a department of the United Kingdom Government, established in 1918 with the responsibility of managing the affairs of the (then newly formed) Royal Air Force. ...
Specification designations Each specification name usually followed a pattern. A leading letter was usually present to identify the aircraft purpose. The codes used included B for "heavy bomber", P for "medium bomber", F for "fighter" and A for "army co-operation". The second part was a number identifying it in sequence and then after the slash, the year it was formulated. Specifications were not always issued in sequence. A bomber is a military aircraft designed to attack ground targets, primarily by dropping bombs. ...
A fighter aircraft is a military aircraft designed primarily for attacking other aircraft, as opposed to a bomber, which is designed to attack ground targets, primarily by dropping bombs. ...
