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

Different types of Davis-type ammunition[2]

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; 1.57 in (40 mm), 2.45 in (62 mm),[4] and 3 in (76 mm) in caliber respectively, firing 2-pound (0.91 kg), 6-pound (2.7 kg), and 12-pound (5.4 kg) 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:

Surviving examples

There are examples at the Naval Aviation Museum at Pensacola, Florida, the Imperial War Museum in London, and the Kentucky Historical Society in Frankfort, Kentucky.[citation needed]
