L3 to provide ALaMO 57 mm guided smart ammunition for US Navy LCS & FFG

L3 Mustang Technology announced in August last year the completion of the Critical Design Review (CDR) phase for the U.S. Navy’s MK 332 Mod 0 High-Explosive, 4-Bolt Guided (HE-4G) projectile. The HE-4G is being developed by L3 Mustang’s Advanced Low-Cost Munitions Ordnance (ALaMO) program.

The 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. Completion of the CDR phase allows the program to progress to qualification testing, munition certification and transition to production.

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.

L3 Mustang was competing against BAE Systems and its ORKA 57 mm guided smart ammunition.
