History

The 25 mm/87 Mk.38 is the US Navy variant of the M242 Bushmaster, an electrically fired "Chain Gun" developed for the United States Army. Seeking a replacement for the ageing Oerlikon 20 mm guns in US Navy service along with their Hispano-Suiza derived AN/M3 and M24 20 mm cannons. Called a chain gun for having a roller chain operate the bolt, the gun was approved for use by the Chief of Naval Operations in 1977 to replace these cannons. However, it would take a full decade before the Navy would evaluate them, with approval coming in 1987 when the Navy was assigned to ensure freedom of navigation in the Persian Gulf as part of Operation Earnest Will. Under the direction of Naval Weapons Support Station Crane, the M242 was fitted to the Mark 88 single mounting to create the Mark 38. Used on all forms of US Navy ships, the manual training and lack of stabilisation created issues when mounted on smaller ships such as the USS Cyclone. The Navy thus upgraded the design to the Mk.38 Mod.2 which improved the interface, added an electro-optical sight, embedded trainer, and a compensator for the ship's role.
