Patriot PAC-3 MSE

The Missile Segment Enhancement (MSE) provides performance enhancements to the battle-proven Patriot Advanced Capability – 3 (PAC-3) missile which will counter evolving threat advancements.  Aerojet Rocketdyne has qualified a larger advanced two-pulse solid rocket motor for the MSE upgrade.  Aerojet Rocketdyne has also qualified the Lethality Enhancer (LE) for the MSE missile.  The LE is a small directional warhead that launches a stream of low-speed steel fragments in the direction of the target in order to enhance the kill probability for certain target types.  These MSE upgrades will support both the existing PATRIOT systems.  The MSE missile is also the baseline interceptor for the multi-national Medium Extended Air Defense System (MEADS).
