27 May 1958: At Lambert Field, St. Louis, Missouri, McDonnell Aircraft Corporation’s Chief Test Pilot (and future company president) Robert C. Little made the first flight of the YF4H-1 prototype. The twin-engine Mach 2+ airplane was the first pre-production model of a new U.S. Navy fleet defense interceptor that would be developed into the legendary F-4 Phantom II fighter bomber.

The flight lasted 22 minutes. Little had planned to go supersonic but a leak in a pressurized hydraulic line caused him to leave the landing gear extended as a precaution, should the back-up hydraulic system also have a problem. This limited the maximum speed of the prototype to 370 knots (426 kilometers per hour). A post-flight inspection found foreign-object damage to the starboard engine.

Initially designated XF4H-1 and assigned Bureau of Aeronautics serial number (“Bu. No.”) 142259, the identifier was changed to YF4H-1. It had been in development for over five years based on a company proposal to the Navy.

The McDonnell YF4H-1 Phantom II was 56 feet, 7.9 inches (17.271 meters) long with a wingspan of 38 feet, 4.89 inches (11.707 meters) and overall height of 16 feet, 3.0 inches (4.953 meters). With wings folded, the airplane’s span was narrowed to 27 feet, 6.6 inches (8.397 meters). The wings were swept 45° at 25% chord. The inner wing had no dihedral, while the outer panels had 12° dihedral. The stabilator had a span of 16 feet, 5.0 inches (5.004 meters), with -23.25° anhedral. The wheelbase of Phantom II’s tricycle undercarriage was 23 feet, 3.25 inches (7.093 meters), with a main wheel tread of 17 feet, 10.46 inches (5.447 meters).

The YF4H-1 prototype was powered by two General Electric J79-GE-2 engines. These were single-spool, axial-flow turbojet engines with a 17-stage compressor and 3-stage turbine. The J79-GE-2 was rated at 10,350 pounds of thrust (46.039 kilonewtons), and 16,150 pounds (71.389 kilonewtons) with afterburner. The engines were 17 feet, 4.0 inches (5.283 meters) long, 3 feet, 2.3 inches in diameter (0.973 meters), and each weighed 3,620 pounds (1,642 kilograms).

The production F4H-1 (F-4B) had a maximum speed of 845 miles per hour (1,360 kilometers per hour) at Sea Level and 1,485 miles per hour (2,390 kilometers per hour) at 48,000 feet (14,630 meters meters). (Mach1.11 and Mach 2.25, respectively). The service ceiling was 62,000 feet (18,898 meters) and maximum range with external fuel was 2,300 miles (3,700 kilometers).

The second prototype YF4H-1, Bu. No. 142260, flown by Commander Lawrence E. Flint, Jr., USN, set a Fédération Aéronautique Internationale (FAI) World Record for Altitude, 6 December 1959, when it zoom-climbed to 30,040 meters (98,556 feet).¹ On 22 November 1961, flown by Lieutenant Colonel Robert B. Robinson, USMC, 142260 also set an FAI World Record for Speed over a Straight 15/25 Kilometer Course, averaging 2,585.425 kilometers per hour (1,606.509 miles per hour).² On 5 December 1961, the same Phantom set an FAI World Record for Altitude in Horizontal Flight at 20,252 meters (66,444 feet) with Commander George W. Ellis, USN, in the cockpit.³

The F-4A through F-4D Phantoms were armed with four AIM-7 Sparrow radar-homing air-to-air missiles, and could carry additional Sparrows or AIM-9 Sidewinder infrared-homing missiles on pylons under the wings. Up to 16,000 pounds (7,257 kilograms) of bombs could be carried on five hardpoints.

McDonnell Aircraft built two YF4H-1 prototypes, followed by 45 F4H-1F (F-4A) Phantom IIs before the F-4B was introduced in 1961. 649 F-4Bs were produced. The initial U.S. Air Force variant was the F-110A Spectre (F-4C Phantom II). McDonnell Douglas delivered its last Phantom II, an F-4E-67-MC, on 25 October 1979. In 21 years, the company had built 5,057 Phantom IIs.

After 11 test flights at St. Louis, Bob Little flew the YF4H-1 west to Edwards Air Force Base in the high desert of southern California where more detailed flight testing and evaluation took place.

On 21 October 1959, a failure of an engine access door led to a cascading series of problems which resulted in the loss of the airplane and death of the pilot, Gerald “Zeke” Huelsbeck.

24 May 1978: McDonnell Douglas delivered the 5,000th F-4 Phantom II, F-4E-65-MC 77-0290, to the United States Air Force in a ceremony at the McDonnell Aircraft Company division at St. Louis, Missouri.¹ This was almost twenty years to the day that the YF4H-1 prototype first flew. [See TDiA, 27 May 1958]

The Mach 2 fighter bomber was developed in the early 1950s as a long range, missile-armed interceptor for the U.S. Navy. The first Phantom II, XF4H-1 Bu. No. 142259, made its maiden flight at St. Louis with future McDonnell Douglas president Robert C. Little at the controls. During flight testing, the U.S. Air Force was impressed by the new interceptor and soon ordered its own version, the F-110A Spectre. Under the Department of Defense redesignation, both Navy and Air Force versions became the F-4. Its name, “Phantom II,” was chosen by James S. McDonnell, and was in keeping with his naming the company’s fighters after supernatural beings.

The Phantom was a very powerful aircraft and set several speed, altitude and time-to-altitude records. The second aircraft, YF4H-1 Bu. No. 142260, flew to 98,557 feet (30,040 meters) on 6 December 1959. On 22 November 1961, the same Phantom set a World Absolute Speed Record of 1,606.509 miles per hour (2,585.425 kilometers per hour). 142260 was entered in the record books again when it established a World Record for Altitude in Horizontal Flight of 66,443.57 feet (20,252 meters), 5 December 1961. Future astronaut Commander John W. Young, United States Navy, flew another Phantom II, Bu. No. 149449, from the runway at NAS Point Mugu on the southern California coast to an altitude of 30,000 meters (82,020.997 feet) in 3 minutes, 50.440 seconds.

The Phantom II first entered combat  during the Vietnam War. It became apparent that the all-missile armament was insufficient for the subsonic dogfights that it found itself in, and a 20 mm Gatling gun was added. Designed as an interceptor, it evolved into a fighter bomber and carried a bomb load heavier that a World War II B-17 bomber. The last American “aces” scored their victories while flying the Phantom over Vietnam.

The F-4 served with the U.S. Air Force until April 1996. The last operational flight was flown by an F-4G Wild Weasel assigned to the Idaho Air National Guard. A total of 5,195 Phantom IIs were built, most by McDonnell Douglas at St. Louis, but 138 were built in Japan by Mitsubishi. The Phantom is still in service with several air forces around the world.

McDonnell Douglas F-4E-65-MC Phantom II 77-0290 was transferred to the Türk Hava Kuvvetleri  (Turkish Air Force), where it retained the U.S. Air Force serial number. It was written off 30 May 1989, however, it was later modernized by Israel Aerospace Industries (IAI) to the F-4E-2020 Terminator standard and as of 25 June 2019, remained in service.

1 February 1975: Major Roger J. Smith, United States Air Force, a test pilot assigned to the F-15 Joint Test Force at Edwards AFB, California, flew the  McDonnell Douglas F-15A-6-MC 72-0119, Streak Eagle, to its eighth Fédération Aéronautique Internationale (FAI) and U.S. National Aeronautic Association time-to-altitude record.

From brake release at Grand Forks Air Force Base, North Dakota, at 913 feet (278 meters) above Sea Level, the F-15 reached 30,000 meters (98,425 feet) in 3 minutes, 27.799 seconds.

This was the eighth time-to-altitude record set by Streak Eagle in 17 days.

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

Streak Eagle carried only enough fuel for each specific flight. 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.

Screen Shot 2016-01-15 at 21.10.22 When the F-15 reached 428 knots (793.4 kilometers per hour), the pilot pulled up into an Immelmann 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 right side up, Streak Eagle continued accelerating to Mach 1.5 while climbing through 36,000 feet (10,973 meters). It would then accelerate to Mach 2.2 and the pilot would pull the fighter up at 4.0 Gs until it reached a 60° climb angle. He held 60° until he had to shut down the engines to prevent them from overheating in the thin high-altitude atmosphere.

After reaching a peak altitude and slowing to just 55 knots (63 miles per hour, 102 kilometers per hour), the airplane was pushed over into a 55° dive. Once it was below 55,000 feet (16,764 meters) the engines would be restarted and Streak Eagle returned to land at Grand Forks.

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.

Because 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, so it was transferred to the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio, in December 1980.

In 1989, 69-7294 was converted to the F-4G Wild Weasel V configuration. The Wild Weasel was an aircraft equipped to attack surface-to-air missile sites and targeting radars, using a variety of high-speed radar-homing missiles. The F-4G had its M-61 Vulcan rotary cannon removed and replaced with a radar homing and warning radar, as well as improvements to the rear cockpit for management of electronic warfare systems. 134 F-4E Phantom II fighters were converted to F-4G Wild Weasels.

The Wild Weasel was next converted to a QF-4G drone. Removed from long term storage and returned to airworthy condition by the Aircraft Maintenance and Regeneration Center, 7294 was flown to Mojave Airport, California, where the drone conversion was completed by Tracor, Inc. Launched from Tyndall Air Force Base, Florida, 69-7294 was “expended” as a remote-controlled aerial target, 4 November 1998.

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 PM Because 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.
