…have recently signed letters of offer and acceptance for Raytheon’s Integrated Defense Systems to begin delivery of the Patriot Advanced Capability-3 Missile Segment Enhancement, the official designation for the PAC-3 MSE. The U.S. has its own PAC-3 MSE production line in Camden, but overseas customers must shop out theirs.Although Germany and the U.S. are both investing in the PAC-3 MSE missile system, their respective projects will not directly interact with one another.
