Context paragraphs:
McDonnell Douglas F-15 Eagle: The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather tactical fighter aircraft designed by McDonnell Douglas (now Boeing) to gain and maintain air supremacy in aerial combat.  Following reviews of proposals, the United States Air Force selected McDonnell Douglas' design in 1967 to meet the service's need for a dedicated air superiority fighter.  The Eagle first flew in July 1972, and entered service in 1976.  It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills scored by the Israeli Air Force.

ACES II: 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.

Developed as a technology demonstrator, the F-15 STOL/MTD carried out research for studying the effects of thrust vectoring and enhanced maneuverability.  The aircraft used for the project was pre-production TF-15A (F-15B) No. 1 (USAF S/N 71-0290), the first two-seat F-15 Eagle built by McDonnell Douglas (out of 2 prototype), the sixth F-15 off the assembly line, and was the oldest F-15 flying up to its retirement.  It was also used as the avionics testbed for the F-15E Strike Eagle program.  The plane was on loan to NASA from the United States Air Force.
