The crew of the USS Gettysburg was using a newly upgraded $600 million anti-aircraft system for the first time in live action when they mistakenly targeted two U.S. Navy FA/18 Hornets on Dec. 21 off the coast of Yemen, forcing the crew of one to eject into the Red Sea.
Gettysburg, a 33-year-old Ticonderoga-class guided missile cruiser, arrived in the Red Sea on Dec. 17 as part of the Harry S. Truman aircraft carrier battlegroup after departing Norfolk, Virginia, in September.
