Lockheed Martin said the contract from the U.S. Defense Department for the GMLRS variant is for three years and carries a value of $79.4 million.
The GMLRS is an all-weather, precision-guided rocket. In testing by the U.S. Army, an ATK-designed alternative warhead for the system demonstrated that it meets performance and mission requirements, reduces technical risk and matches current weapon flight characteristics.
As envisaged, the new warhead would be a drop-in replacement for the warhead already in use.
Under terms of the contract, Lockheed's work would involve system performance, warhead qualification and ability to be produced.
"We are eager to move forward with the Alternative Warhead Program and provide soldiers and marines with a precision-engagement capability that meets their evolving requirements," said Scott Arnold, vice president of precision fires for Lockheed Martin's Missiles and Fire Control business.
"GMLRS has been a trusted weapon of choice in current combat operations in Afghanistan, and continues to exceed operational-readiness requirements."
