Lockheed Martin successfully conducted two Guided Multiple Launch Rocket System (GMLRS) Unitary rocket Phase II Product Qualification Test flights recently at White Sands Missile Range, NM.

These "GPS2 jamming" tests demonstrated both GMLRS rocket performance while in a GPS jamming environment at long range, as well as the functionality of the warhead using the Point Detonating fuze within the jamming environment. All tests objectives were achieved.

The two missions were fired from the HIMARS launcher using one rocket per mission after the launch pod container was conditioned to the "hot" temperature extreme. The first rocket employed the GMLRS "vertical trajectory shaping" software that allows the rocket to impact the target vertically, while the second incorporated the "nominal trajectory shaping" software, which allows for the standard ballistic trajectory flight pattern. Both rockets flew their expected trajectories and functioned as designed in the target area.

These tests validated a very tough requirement. This means that GMLRS Unitary can be effectively and productively employed every time - when low collateral damage is a concern and in close proximity to friendly troops - given its surgical precision.

The tests further qualified the effects of the unitary warhead on the target following detonation, and continued to demonstrate that the Follow-On configuration hardware and software design complies with the program objectives and requirements.

This mission specifically demonstrated rocket performance and provided system performance data in a GPS jamming environment.
