ATK announced that it has been selected by the U.S. Army to develop an alternative warhead for the Guided Multiple Launch Rocket System (GMLRS). ATK was one of three companies competing to proceed into the Engineering and Manufacturing Design and Demonstration (EMDD) phase of the program. ATK will be a subcontractor to GMLRS prime contractor Lockheed Martin. The GMLRS alternative warhead eliminates the use of submunitions, but performs as a drop-in replacement for the currently-fielded Dual-Purpose Improved Conventional Munition (DPICM) warhead. During live-fire testing by the U.S. Army, ATK's alternative warhead -- featuring ATK's Lethality Enhanced Ordnance (LEO) design -- demonstrated that it meets performance and mission requirements, lowers technical risk and matches current weapon flight characteristics without modifications to the existing GMLRS delivery system. In addition, the design improves user safety by lessening the risk of chain-reaction explosions should the warhead be struck by bullets or fragments, or encounter other hazardous events.
