Davis gun
Script error: No such module "Infobox".Script error: No such module "Check for unknown parameters". The Davis gun was the first true recoilless gun developed and taken into service. It was developed by Commander Cleland Davis[1] of the United States Navy in 1910, just prior to World War I.
Development
Davis' design connected two guns back to back, with the backwards-facing gun loaded with lead balls and grease of the same weight as the shell in the other gun, acting as a counter. His idea was used experimentally by the British and Americans as an anti-Zeppelin and anti-submarine weapon[3] mounted on the British Handley Page O/100 and O/400 bombers and the American Curtiss Twin JN[1] and Curtiss HS-2L and H-16 flying boats. The direct development of the gun ended with the end of World War I in November 1918, but the firing principle has been copied by later designs.
Description
The gun was made in three sizes: 2-pounder, 6-pounder and 12-pounder; Script error: No such module "convert"., Script error: No such module "convert".,[4] and Script error: No such module "convert". in caliber respectively, firing Script error: No such module "convert"., Script error: No such module "convert"., and Script error: No such module "convert". shells. The 3-inch gun carried a pressure of 15 tons per square inch (2,109 kg per cm2) when fired.[5] Usually a Lewis machine gun was mounted on top of the Davis gun's barrel for use in sighting and as an auxiliary and anti-aircraft weapon.
Aircraft used
The gun was tested on various aircraft and some aircraft were designed to carry the gun:
- Airco DH.4
- Armstrong-Whitworth FK.5 and FK.6 - "escort fighter" triplane
- Curtiss F5L - patrol flying boat used by US Navy
- Felixstowe Porte Baby - large flying boat
- Handley-Page O/100 - twin engined bombers with 6pdr Davis gun added for ground attack and anti-submarine
- Handley-Page O/400 - larger version of the O/400
- Naval Aircraft Factory N-1 - patrol floatplane designed by US Navy, four prototypes built, project canceled[6]
- Short Type 184
- Short 310-B seaplane
- Pemberton-Billing PB.29E
- Pemberton-Billing PB.31E - long endurance anti-Zeppelin night fighter with 37mm Davis gun, prototypes only
- Robey-Peters RRF.25 Gun-carrier - two Davis guns. Single prototype for Royal Navy completed
