3 April 1962: At NAS Point Mugu, Ventura County, California, a future NASA astronaut, United States Navy test pilot Commander John Watts Young, set a new Fédération Aéronautique Internationale (FAI) time-to-altitude world record by flying his McDonnell Aircraft Corporation F4H-1 Phantom II, Bureau of Aeronautics serial number (Bu. No.) 149449, from the surface to 25,000 meters (82,021 feet) in 3 minutes, 50.44 seconds.¹

John Young had set another FAI record on 21 February, reaching a height of 3,000 meters (9,843 feet) in 34.523 seconds with the Phantom II at NAS Brunswick, Maine.² Young set a total of 21 FAI records. Three remain current.

This was one of a series of time-to-altitude record flights flown at with F4H-1 149449 during February, March and April 1962. Flown by four other pilots, 149449 also set time-to-altitude records for 3,000, 6,000, 9,000, 12,000, 15,000, and 20,000 meters.

Point Mugu’s Runway 21 ends on the edge of the Pacific Ocean and the elevation is 9 feet (2.7 meters) above Sea Level. The restricted airspace of the Pacific Missile Test Range assured that these flights could be conducted safely and without interfering with civilian air traffic. The U.S. Air Force had used the same runway when it conducted time-to-altitude record flights with a Lockheed F-104A Starfighter in 1958.

John Young was a test pilot assigned to the Naval Air Test Center, NAS Patuxent River, Maryland, where he was a project officer for F4H and F8U armament systems. He was selected as a NASA astronaut and served as Pilot of Gemini III; backup pilot, Gemini IV; Commander for Gemini 10; Command Module Pilot on Apollo 10; back-up commander for Apollo 13; Commander, Apollo 16; and back-up commander for Apollo 17. Later, he was Commander of the maiden flight of the space shuttle Columbia STS-1 and again for STS-9. He was in line to command STS-61J.

McDonnell F4H-1 Phantom II Bu. No. 149449, redesignated F-4B-11-MC, served with VF-96 aboard the aircraft carrier USS Ranger (CV-61), VF-151 aboard USS Coral Sea (CV-43) and was later assigned to Marine Air Group 13, VMFA-323, “Death Rattlers,” based at Chu Lai Air Base, Republic of South Vietnam.

On 2 August 1968, 149449 was hit by small arms fire near An Hoa, 17 miles southeast of Da Nang. On returning the damaged airplane to Chu Lai, the Phantom’s landing gear could not be extended. The pilot, Major DanieI I. Carroll, USMC, and Weapons System Officer, First Lieutenant R.C. Brown, USMC, ejected one mile (1.6 kilometers) off the coast. Both were rescued by a U.S. Army helicopter.

The record-setting Phantom II was lost in the South China Sea.

26 January 1975: In a continuing series of time-to-altitude records, Major David W. Peterson, U.S. Air Force, a test pilot assigned to the F-15 Joint Test Force at Edwards AFB, California, ran the engines of the McDonnell Douglas F-15A-6-MC, 72-0119, Streak Eagle to full afterburner while it was attached to a hold-back device on the runway at Grand Forks Air Force Base, North Dakota. The fighter was released and 161.025 seconds later it climbed through 82,020.997 feet (25,000 meters), setting another Fédération Aéronautique Internationale (FAI) world record. This was the seventh time-to-altitude record set by the modified F-15 in just ten days.

Streak Eagle is a very early production F-15A-6-MC Eagle, a single-seat, twin-engine air superiority fighter. It is 63 feet, 9.0 inches (19.431 meters) long with a wingspan of 42 feet, 9.7 inches (13.048 meters) and overall height of 18 feet, 5.4 inches (5.624 meters). The F-15A has an empty weight of 25,870 pounds (11,734 kilograms) and its maximum takeoff weight (MTOW) is 44,497 pounds (20,184 kilograms).

The F-15A is powered by two Pratt & Whitney JTF22A-25A (F100-PW-100) afterburning turbofan engines. 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 engine has a Maximum Continuous Power rating of 12,410 pounds of thrust (55.202 kilonewtons); 14,690 pounds (65.344 kilonewtons, 30-minute limit; and a maximum 23,840 pounds (106.046 kilonewtons), 5-minute limit. 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 502 knots (578 miles per hour/930 kilometers per hour). It has a maximum speed of 893 knots (1,028 miles per hour/1,654 kilometers per hour) at 10,000 feet (3,048 meters), and 1,434 knots (1,650 miles per hour/2,656 kilometers per hour) at 45,000 feet (13,716 meters). The ceiling is 63,050 feet (19,218 meters) at maximum power. It can climb at an initial 67,250 feet per minute (342 meters per second) from Sea Level, and with a thrust-to-weight ratio of 1.15:1, The F-15 can climb straight up. The Eagle’s combat radius is 638 nautical miles (734 statute miles/1,182kilometers).

The F-15A is armed with one General Electric M61A1 Vulcan 20mm rotary cannon with 938 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.

Streak Eagle was specially modified for the record attempts. Various equipment that would not be needed for these flights was eliminated: The flap and speed brake actuators, the M61A1 Vulcan 20 mm cannon and its ammunition handling equipment, the radar and fire control systems, unneeded cockpit displays and radios, and one generator.

Other equipment was added: A long pitot boom was mounted at the nose with alpha and beta vanes, equipment for the pilot’s David Clark Company A/P-225-6 full pressure suit, extremely sensitive accelerometers and other instrumentation, extra batteries, an in-cockpit video camera aimed over the pilot’s shoulder, and perhaps most important, a special hold-down device was installed in place of the fighter’s standard arresting hook.

These changes resulted in an airplane that was approximately 1,800 pounds (817 kilograms) lighter than the standard production F-15A. This gave it a thrust-to-weight ratio of 1.4:1.

The flight profiles for the record attempts were developed by McDonnell Douglas Chief Experimental Test Pilot, Charles P. “Pete” Garrison (Lieutenant Colonel, U.S. Air Force, Retired).

Streak Eagle carried only enough fuel for each specific flight, and weighed 36,709 pounds (16.650.9 kilograms). It was secured to the hold-back device on the runway and the engines were run up to full afterburner. It was released from the hold-back and was airborne in just three seconds.

When the F-15 reached 428 knots (793.4 kilometers per hour), the pilot pulled up into an Immelman turn, holding 2.5 Gs. Streak Eagle would arrive back over the air base, in level flight at about 32,000 feet (9,754 meters), but upside down. Rolling up right, Streak Eagle continued accelerating to Mach 1.8 and the pilot would pull the fighter up at 4.0 Gs until it reached a 55° climb angle. He held 55° until he had reached 25,000 meters, then pushed over. Streak Eagle returned to land at Grand Forks.

Screen Shot 2016-01-25 at 5.46.11 PMBecause Streak Eagle was a very early production airplane, its internal structure was weaker than the final production F-15A standard. It was considered too expensive to modify it to the new standard. It was transferred to the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio, in December 1980.
