Question: What company provided the ejection seat system for the fighter aircraft that had wings built by Boeing for the United States Air Force's Advanced Tactical Fighter program?

 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. ACES II is an ejection seat system manufactured by the United Technologies Aerospace Systems (UTAS) division of the United Technologies Corporation (UTC).  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. <SEP> Boeing 818 was the Boeing's candidate for the U.S. military's TFX fighter completion.  The U.S. Air Force and Navy were both seeking new aircraft when Robert McNamara was appointed U.S. Secretary of Defense in January 1961.  The aircraft sought by the two armed services shared the need to carry heavy armament and fuel loads, feature high supersonic speed, twin engines and two seats, and probably use variable geometry wings.  On 14 February 1961, McNamara formally directed the services to study the development of a single aircraft that would satisfy both requirements.  Early studies indicated that the best option was to base the design on the Air Force requirement, and use a modified version for the Navy.  In June 1961, Secretary McNamara ordered the go ahead of Tactical Fighter Experimental (TFX) despite Air Force and Navy efforts to keep their programs separate. <SEP>  The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF).  The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems. <SEP> The Lockheed/Boeing/General Dynamics YF-22 was an American single-seat, twin-engine fighter aircraft technology demonstrator designed for the United States Air Force (USAF).  The design was a finalist in the USAF's Advanced Tactical Fighter competition, and two prototypes were built for the demonstration/validation phase of the competition.  The YF-22 won the contest against the Northrop YF-23, and entered production as the Lockheed Martin F-22 Raptor.  The YF-22 has similar aerodynamic layout and configuration as the F-22, but with differences in the position and design of the cockpit, tail fins and wings, and in internal structural layout.
