Lockheed Martin said it delivered Sweden’s first Patriot Advanced Capability-3 (PAC-3) Missile Segment Enhancement (MSE) interceptors in April.
U.S. and Swedish officials formalized an agreement for Sweden to purchase PAC-3 MSE interceptors and related support equipment in August 2018.
The PAC-3 MSE’s two-pulse solid rocket motor provides increased performance in both altitude and range while employing the same Hit-to-Kill technology that the PAC-3 CRI missile brings to the Patriot system.
