Aerojet Technology has successfully flight tested its new warhead system that can reduce unexploded ordnance (UXO) on the US Army’s guided multiple-launch rocket system (GMLRS).

Each warhead flight tested under the GMLRS alternative warhead programme (AWP) has used a highly reliable inventory fuse to reduce the chance of leaving UXO in the theatre.

Aerojet Technology vice-president and deputy to the president Dick Bregard said the new technology offered unique accuracy in controlling the warhead’s lethal effects, and represents a lucrative method to take advantage of the GMLRS missile’s precision-guidance capabilities.

“Thus, warfighters can engage and neutralise targets using fewer missiles while reducing the possibility of collateral damage and UXO on the battlefield,” he said.

After evaluating the test results and cost proposals, the US Army will select the production alternative warhead supplier in the summer.

The first live-fire, missile-delivered performance tests were conducted by the US Army at White Sands Missile Range, New Mexico.
