January 13, 1990
Final assembly of the first YF-22 prototype begins in California.
Final assembly of the second YF-22 prototype begins.
June 8, 1990
Pratt & Whitney delivers its first flyable prototype YF119 engine to Lockheed.
July 17, 1990
Pratt & Whitney delivers its second flyable prototype engine to Lockheed.
Prototype YF119 engine YF604-2 completes accelerated mission testing. Also, prototype YF119 engine YF605-1 completes flight clearance testing for the YF-22 at Arnold Engineering and Development Center in Tennessee.
August 28, 1990
The YF-22A is unveiled in ceremonies at Lockheed Plant 10 in Palmdale. This first Prototype Air Vehicle (PAV-1) is powered by two General Electric YF120-GE-100 turbofan engines.
September 29, 1990
First flight of prototype. Dave Ferguson was the pilot.
October 25, 1990
Maj. Mark Shackelford becomes the first Air Force pilot to fly the YF-22 prototype. This flight also marks the first time the YF-22 is flown at supersonic speeds.
October 26, 1990
The first aerial refueling of the YF-22 takes place. The tanker is a Boeing KC-135.
October 29, 1990
Pratt & Whitney delivers its third flyable prototype YF119 engine (which is used as a spare) to Lockheed.
October 30, 1990
Lockheed test pilot Tom Morgenfeld makes first flight of the number-two YF-22 prototype, flying from Palmdale to Edwards. Two P&W YF119-PW-100 turbofan engines powered this aircraft (PAV-2).
November 3, 1990
The YF-22's ability to supercruise, or fly at supersonic speeds without afterburners, is demonstrated for the first time. (Test carried out with PAV-1).
November 15, 1990
The General Electric-powered YF-22's thrust vectoring capability is demonstrated for the first time.
November 23, 1990
The Pratt & Whitney-powered YF-22 (PAV-2) demonstrates its supercruise capability for the first time.
November 28, 1990
General Dynamics test pilot Jon Beesley (flying PAV-2) fires an unarmed AIM-9 Sidewinder heat-seeking air-to-air missile over the range at the Naval Weapons Center at China Lake, California. This is the first live missile firing in the entire ATF program.
December 1, 1990
The Pratt & Whitney-powered YF-22's thrust vectoring capability is demonstrated for the first time.
December 10, 1990
Testing of the YF-22's ability to reach high angles of attack (or high alpha) attitudes begins. (All high angle of attack tests are conducted with PAV-1).
December 11, 1990
The YF-22s are flown in formation for the first time.
December 17, 1990
High angle of attack (high alpha) testing is completed. The YF-22 attains an unprecedented 60-degree angle of attack attitude and remains in full control.
December 20, 1990
Lockheed test pilot Tom Morgenfeld (flying PAV-2) fires an unarmed AIM-120A radar-guided Advanced Medium-Range Air-to-Air Missile (AMRAAM) over the Pacific Missile Test Range at Point Mugu, Calif.
December 28, 1990
The YF-22's maximum mach number (Mach 2+) is achieved. During the dem/val flight test program, PAV-1 was flown 43 times for 52.8 hours and PAV-2 was flown 31 times for 38.8 hours. In total, the two YF-22s were flown a total of 74 times, accumulating 91.6 hours.
December 31, 1990
Lockheed, Boeing and General Dynamics team submits its proposal, the F-22 to the Air Force.
