30mm DS30M Mark 2 Automated Small Calibre Gun
The 30mm DS30M Mark 2 is a ship-protection system made by MSI-Defence Systems consisting of a 30mm Mark 44 Bushmaster II cannon on an automated mount. It was designed to defend Royal Navy frigates from fast inshore attack craft armed with short-range missiles, rockets, rocket-propelled grenades, heavy machine guns or explosives. It replaced in this role the 30mm Oerlikon KCB gun on the DS30B, a similar powered mounting. The DS30M has also been added to patrol boats and corvettes for the Iraqi and Omani navies respectively.
==Description==
The DS30M Mark 2 system consists of a 30mm Mark 44 Bushmaster II〔 on a fully automated mount〔 with an off-mount electro-optical director (EOD).〔 The gun and the EOD are controlled from a remote operator console elsewhere on the ship. The "mount is a single cannon naval mount that is gyro stabilized, electrically operated and self contained gun mounting featuring a choice of cannon, control mode and sights. It has low magnetic, radar and IR signatures and excellent ergonomic availability, reliability and maintainability (ARM)."〔(Global Security ''Mk 44 Bushmaster II 30/40mm Automatic Cannon / Mk 46 Weapon Station'' ).〕 In theory "the unique dual feed system of the Bushmaster series allows the operator to select different types of ammunition for use against a variety of targets. The safety, reliability and low life-cycle costs of the Bushmaster system added to its overall value."〔 However photographs show only a single ammunition feed.〔
