Passage: ACES II is an ejection seat system manufactured by the United Technologies Aerospace Systems (UTAS) division of the United Technologies Corporation (UTC).  ACES is an acronym for Advanced Concept Ejection Seat.  It is used in Fairchild Republic A-10 Thunderbolt II, McDonnell Douglas F-15 Eagle, General Dynamics F-16 Fighting Falcon, Lockheed Martin F-22 Raptor, Lockheed F-117 Nighthawk, Rockwell B-1 Lancer, WB-57, and Northrop Grumman B-2 Spirit aircraft.  Over 10,000 ACES II seats have been produced with over 5,000 actively flying throughout the world as of 2013.  It is known throughout the industry as the lowest life cycle cost third generation seat due to the USAF owning the rights to the seat, facilitating competitive replacement part procurement.  In addition, the buying power of 5,000 in-service seats and previous service life extension programs have further driven down support costs.
