What systems does each ship have for self-defense?
For air defense each LPD has the Mk 31 Mod 1 Guided Missile Weapons System with its RIM 116 Rolling Airframe Missile (RAM), which is used to engage anti-ship missiles or high-speed aircraft. Each ship has two RAM launchers. For defense against surface targets, the ships posses the naval version of the Marine Corps’ Expeditionary Fighting Vehicles’ (EFV) 30mm gun. It provides greater accuracy and lethality than the 25mm gun currently found on other ships.
