History

The 2-pounder Rolls Royce is the naval variant of the Rolls-Royce Type BH aircraft cannon. While first built for aircraft, it was never used in that capacity outside of testing as the Royal Navy decided in 1943 that rockets such as the RP-3 were the better choice for aerial anti-armour weapon and before that, adopted the competing Vickers S. The Royal Navy, however, found a use of the design in 1940 realizing their coastal defense boats needed a weapon to counter German E-boats. In September, the 2-pounder Rolls Royce was tested off Whale Island by the Royal Navy and, after ironing out the problems, was adopted in 1941. Used primarily on the Fairmile C, it was also used on motor gunboats such as MGB-75 which were used to both defend the British coast and the Mediterranean Sea as an anti-aircraft gun. Because Minister of Aircraft Production Lord Beaverbrook forbade Rolls Royce from building the design themselves, the 600 guns produced for the Royal Navy were subcontracted to the British United Shoe Company. Replacing some of their earlier Oerlikon 20 mm cannons, the Rolls-Royce was itself eventually replaced by a variant of the Molins Class M, another design first built for aircraft use.
