Lockheed Martin successfully conducted the first flight of the new Guided Multiple Launch Rocket System (GMLRS) Alternative Warhead at White Sands Missile Range

Launched from a HIMARS mobile launcher, the GMLRS rocket flew 35 kilometers to the target, where the warhead detonated. This flight followed a successful ground-based test of the Alternative Warhead two weeks earlier.

The Alternative Warhead Program (AWP) is part of a U.S. Department of Defense plan to phase out submunitions, and is designed to achieve the same area-effects as the GMLRS submunitions warhead, but without the lingering danger of undetonated explosives.

The GMLRS Alternative Warhead is unitary and fits within the existing GMLRS architecture as a replacement for the Dual-Purpose Improved Conventional Munition warhead. The Alternative Warhead is being developed by ATK under subcontract to Lockheed Martin.

In April 2012, Lockheed Martin received a $79.4 million contract from the U.S. Department of Defense to develop AWP. Under the terms of the contract, the EMD phase of the program runs 36 months, focusing on system performance, warhead qualification and producibility.
