The US Army has awarded a $227m contract to Lockheed Martin for Lot 10 production of the guided multiple launch rocket system (GMLRS) Unitary.

The contract, which includes the first order of GMLRS alternative warhead production, will also cover a US Government foreign military sale of GMLRS Unitary rockets to Bahrain and the United Arab Emirates (UAE).

Lockheed Martin Missiles and Fire Control, Tactical Missiles vice-president Ken Musculus said: "GMLRS is a combat proven precision-strike system.

"We are confident that the new GMLRS Alternative Warhead will also provide reliable, highly accurate capability for our domestic and international customers."

Work on the contract will be performed at the company’s facility in Camden, Arkansas, US.

"GMLRS is a combat proven precision-strike system."

To date, more than 25,000 GMLRS rockets have been produced by the company at its Camden facility.

Packaged in an MLRS launch pod, the all-weather GMLRS rocket is fired from the Lockheed HIMARS or M270 family of launchers during combat operations.

The alternative warhead has been designed to achieve area-effects requirement similar to the old MLRS submunition warheads and can engage the same target set, while eliminating the danger of unexploded ordnance.

Production of MLRS rockets with submunition warheads was stopped by the company nearly seven years ago.

The GMLRS rocket is also used by the armed forces of France, Germany, Italy, the UK, Japan, Jordan, Singapore, Bahrain and the UAE.
