The MK 332 Mod 0 High Explosive 4 Bolt Guided (HE-4G) is a low-cost 57 mm guided smart ammunition intended for use on the Navy’s Littoral Combat Ship and new Fast Frigate, as well as the U.S. Coast Guard’s National Security and Offshore Patrol Cutters. The ALaMO Program qualifies the 57 mm MK 332 Mod 0 High Explosive, 4-Bolt Guided (HE-4G) Cartridge for the United States Navy (U.S. Navy ). Completion of the (Critical Design Report) (CDR) phase allows the program to progress to qualification testing, munition certification and transition to production. L3 Mustang was competing against BAE Systems and its ORKA 57 mm guided smart ammunition.

ALaMO is designed to help surface vessels fitted with the BAE Systems Mk110 defend against asymmetric threats, such as swarming small boats and Unmanned Aircraft Systems. L3 Mustang’s ALaMO program has successfully demonstrated this capability in tests at the U.S. Navy’s Potomac River Test Range in Dahlgren, Virginia, by hitting a moving surface target at significantly longer ranges than possible with unguided projectiles. This improved accuracy allows for a significant reduction in cost and adds depth to the ship’s magazine by requiring fewer rounds per target.
