context_page_description: 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.
