On June 26, 2025, at the White Sands Missile Range (WSMR), the U.S. Army and Lockheed Martin conducted a critical flight test mission, showcasing the evolving capability of PAC-3 MSE within the PATRIOT system. During the flight test, PAC-3 Missile Segment Enhancement (MSE) interceptors engaged an Air Breathing Threats (ABTs). The missions used software updates and new seeker algorithm designs for the PAC-3 MSE. These enhanced capabilities enable the PATRIOT system to effectively counter emerging threats in contested environments. The PAC-3 Missile Segment Enhancement (MSE) is an evolution of the battle-proven PAC-3 Missile.
“We’re continuously evolving PAC-3 to address the increasingly complex threat landscape. Recent global events highlight the vital role PAC-3 plays in delivering integrated air and missile defense to protect lives, infrastructure and strategic assets. As we address the growing international demand for PAC-3’s proven capabilities,this flight test reinforces our commitment to delivering cutting-edge technology that enhances the system’s ability to detect, track, and engage advanced threats,” said Brian Kubik, Vice President of PAC-3 Programs.
PAC-3 Missile Segment Enhancement (MSE) is combat proven against advanced threats including hypersonics, tactical ballistic missiles, cruise missiles and air breathing threats. PAC-3 missiles defend against incoming threats through direct body-to-body contact delivering exponentially more kinetic energy on the target than can be achieved with blast fragmentation mechanisms. The PAC-3 MSE design utilizes the latest technology to significantly increase performance. The PAC-3 MSE incorporates a larger, dual pulse solid rocket motor; larger fins; and upgraded actuators and thermal batteries to accommodate increased performance. The modifications extends the missile’s reach.
The hit-to-kill PAC-3 MSE provides performance enhancements that counter evolving threat advancements. The enhancements ensure the PAC-3 Missile Segment of the PATRIOT Air Defense System is capable of engaging new and evolving threats. The hit-to-kill PAC-3 Missile is the world’s most advanced, and capable theater air defense missile and defender against the entire threat to the PATRIOT Air Defense System: Tactical Ballistic Missiles (TBMs) carrying weapons of mass destruction, evolving cruise missiles and aircraft. The PAC-3 MSE is packaged in a single canister that stacks to provide logistical flexibility. Twelve individual PAC-3 MSE Missiles can be loaded on a PATRIOT Launcher or a combination of six MSEs and eight PAC-3 Missiles (two four packs) can be loaded.
