High Quality Content by WIKIPEDIA articles! The Type 96 25mm Gun (???????????, Jy?roku-shiki nijy?go-miri K?kakukij??) was a automatic cannon used by the Imperial Japanese Navy during World War II. It was primarily used as an anti-aircraft gun in fixed mounts with between one and three guns, but was designed as a dual-purpose weapon for use against armor as well.In 1935 the Imperial Japanese Navy decided to replace the earlier 40 mm Vickers "pom-pom" guns with a 25 mm Hotchkiss design. A party of Japanese officers and engineers traveled to France to evaluate the design in 1935 and an order was placed for a number of guns and mounts for evaluation. Firing tests of these guns were conducted at Yokosuka Naval Arsenal in 1935. The first few weapons were built in France under the designation ?Type 94? and ?Type 95?, with the mass production model produced at the Yokosuka Arsenal being designated ?Type 96?.
