List Of Air Ministry Specifications
This is a partial list of the British Air Ministry (AM) specifications for aircraft. A specification stemmed from an Operational Requirement, abbreviated "OR", describing what the aircraft would be used for. This in turn led to the specification itself, e.g. 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 be invited to present design proposals to the Ministry, following which prototypes of one or more of the proposals might be ordered for evaluation. On very rare occasions, a manufacturer would design and build an aircraft using their own money as a "Private Venture" (PV). 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 issue a specification based on the Private Venture aircraft.
The system of producing aircraft to a specification ran from 1920 to 1949 during which the Air Ministry was replaced by first the Ministry of Aircraft Production (MAP) and then the Ministry of Supply (MoS). The system was applied to commercial aircraft as well, two being de Havilland Comet and Vickers Viscount. During the period, over 800 specifications were issued.

“Sheathey call him Scholar Jack
Went down the list of the dead.
Officers, seamen, gunners, marines,
The crews of the gig and yawl,
The bearded man and the lad in his teens,
—Joseph I. C. Clarke (18461925)
“the eave-drops fall
Heard only in the trances of the blast,
Or if the secret ministry of frost
Shall hang them up in silent icicles,
Quietly shining to the quiet Moon.”
—Samuel Taylor Coleridge (17721834)
“I never approve, or disapprove, of anything now. It is an absurd attitude to take towards life. We are not sent into the world to air our moral prejudices. I never take any notice of what common people say, and I never interfere with what charming people do.”
—Oscar Wilde (18541900)
“Religious literature has eminent examples, and if we run over our private list of poets, critics, philanthropists and philosophers, we shall find them infected with this dropsy and elephantiasis, which we ought to have tapped.”
—Ralph Waldo Emerson (18031882)
