Sweden has signed a Letter of Offer and Acceptance to purchase Raytheon's Patriot air and missile defense system from the US Army.
Patriot consists of radars, C2 technology and multiple types of interceptors, all working together to detect, identify and defeat tactical ballistic missiles, cruise missiles, UAS, advanced aircraft and other threats.
Separately, Sweden has also formalised an agreement with the US government to purchase Lockheed Martin's Patriot Advanced Capability-3 (PAC-3) Missile Segment Enhancement (MSE) missiles and related support equipment.
PAC-3 MSE is a high-velocity interceptor that defends against incoming threats. The missile uses hit-to-kill technology, which engages threats through kinetic energy via body-to-body contact. The upgraded PAC-3 MSE adds a dual-pulse solid rocket motor, providing increased performance in altitude and range.
