Raytheon to provide new PERM guided mortar munition to the U.S. Marine Corps 41112153.

EFSS consists of two Internally Transportable-Light Strike Vehicles carrying a mortar tube and ammunition supply that can be moved as a single package in the belly of an MV-22B Osprey or slung under a CH-53E Super Stallion. EFSS can be deployed aboard amphibious ships with a small logistics footprint or inserted vertically by the MV-22 Osprey. Once ashore EFSS provides sustained, responsive, 24/7 artillery support with a highly lethal suite of munitions.

Currently in testing, PERM is expected to be delivered in fiscal year 2018 with a total munitions requirement of 3,113 rounds. PERM munitions were employed in field tests in mountainous firing range, validating the munitions’ maximum and minimum range performance, with demonstrated accuracy levels exceeding the services’ requirements.

A unique capability, provided by the efficient aerodynamic design combining tail fins and flaps in the mid-body, enables complex trajectory shaping techniques enabling the round to hit target in steep reverse slopes in mountainous terrain – a task that is often impossible to accomplish by other projectiles, using ballistic trajectory.

MCSC oversees the development, acquisition and lifecycle logistics of Marine Corps ground weapon and information technology system programs.
