Raytheon reports successful PERM GTH testing

Raytheon’s Precision Extended Range Munition (PERM) has successfully completed its first two Guide to Hit (GTH) test series, confirming the round’s structural integrity and kinematic capability when fired from a smooth bore mortar tube.

Raytheon said that the testing confirmed that after launch, the canards and tail fins deploy and the round transitions to steady flight; and that the round would meet expected range and impact angle requirements. The next series of GTH tests will be conducted out of a rifled mortar tube.

Tom Bussing, vice president, advanced missile systems, Raytheon Missile Systems, said: ‘Raytheon is leveraging our extensive experience with precision artillery and munitions to meet an aggressive, 18-month development schedule. Our PERM solution's exceptional accuracy not only means long-range precision fire support; it results in less collateral damage and logistical burden for marine corps expeditionary forces.’

Raytheon is under contract to deliver mature, production-representations of the 120mm extended range, guided mortar munition for a live-fire demonstration phase by the US Marine Corps in early 2014. An ATK-General Dynamics team is also in the running for the programme.

Once fielded, PERM will be used with the M327 rifled towed mortar, the primary weapon system of the Expeditionary Fire Support System. EFSS provides all-weather, ground-based responsive close fires in support of the Marine Air-Ground Task Force.
