Through an unbelievable series of events which will not be discussed in this report, the Army got the Hispano-Suiza 820 (M139) gun and the ammunition that went with it. (Perhaps the Army didn't know exactly what they wanted, but this certainly was not it.)
The Hispano-Suiza gun was never known for its reliability, regardless of the size in which it was built. Also it had to be kept clean and well lubricated, a difficult requirement in dusty or sandy environments.
Not exactly a ringing endorsement of the Hs.820 cannon from the USAF Armament Laboratory.
