14 November 1974: The very first operational McDonnell Douglas F-15A Eagle air superiority fighters were delivered to the 555th Tactical Training Squadron, 58th Tactical Training Fighter Wing at Luke Air Force Base, west of Phoenix, Arizona. The acceptance ceremony was presided over by President Gerald R. Ford.
“. . . I am here today to underscore to you and to the world that this great aircraft was constructed by the American people in the pursuit of peace. Our only aim with all of this aircraft’s new maneuverability, speed, and power is the defense of freedom.
“I would rather walk a thousand miles for peace than to have to take a single step for war.
“I am here to congratulate you: the United States Air Force, McDonnell Douglas, Pratt and Whitney, all of the many contractors and workers who participated in this very, very successful effort, as well as the pilots who have so diligently flight-tested the F-15 Eagle. All of you can underline my feeling that we are still pilgrims on this Earth, and there still is a place for pioneers in America today.”
The F-15A Eagle is a Mach 2.5+ fighter with outstanding acceleration and maneuverability. The F-15A was produced from 1972 to 1979. It is a single-seat, twin-engine air superiority fighter, 63 feet, 9 inches (19.431 meters) long, with a wingspan of 42 feet, 9½ inches (13.043 meters) and overall height of 18 feet, 5½ inches (5.626 meters). The F-15A has an empty weight of 27,000 pounds (12,247 kilograms) and its maximum takeoff weight (MTOW) is 66,000 pounds (29,937 kilograms).
The F-15A is powered by two Pratt & Whitney JTF22A-25A (F100-PW-100) afterburning turbofan engines capable of producing 14,670 pounds of thrust (65.255 kilonewtons), and 23,830 pounds (105.996 kilonewtons), each, with afterburner. The F100 is a two-spool, axial-flow turbine engine with a 3-stage fan section; 10-stage compressor; single chamber combustion section; and 4-stage turbine (2 low- and 2 high-pressure stages). The F100-PW-100 is 191 inches (4.851 meters) long, 46.5 inches (1.181 meters) in diameter, and weighs 3,035 pounds (1,376.7 kilograms).
The cruise speed of the F-15A Eagle is 570 miles per hour (917 kilometers per hour). It has a maximum speed of 915 miles per hour (1,473 kilometers per hour) at Sea Level, and 1,650 miles per hour (2,655 kilometers per hour) at 36,000 feet (10,973 meters). The service ceiling is 65,000 feet (19,812 meters). It can climb in excess of 50,000 feet per minute (254 meters per second), and with a thrust-to-weight ratio of 1.15:1, could climb straight up. The Eagle’s combat radius is 1,222 miles (1,967 kilometers).
The F-15A is armed with one General Electric M61A1 Vulcan 20mm rotary cannon with 940 rounds of ammunition, four AIM-7 Sparrow radar-guided missiles and four AIM-9 Sidewinder heat-seeking missiles.
384 F-15A Eagles were built before production shifted to the improved F-15C version. As F-15Cs became operation, the F-15As were transferred to Air National Guard units assigned to defend continental U.S. airspace. The last F-15A was retired from service in 2009.
