The Air Force F-15 "Eagle" advance tactical fighter unofficially broke all existing world time-to-climb records during test operations conducted at Grand Forks AFB, ND. The eight records were previously held by the Soviet Union and the U.S. Navy.
While breaking the time-to-climb records, the flights also provided the Air Force with valuable information on the performance of the F-15 at extremely high altitudes and the operation of the various aircraft systems under these conditions.
Records broken include the 20,000 meter (65,617 ft), 25,000 meter (82,021 ft) and 30,000 meter (98,425 ft) time-to-climb records set by a Russian MIG-25/E-2-66/"Foxbat" fighter in 1973. For example, time to 20,000 meters (65,617 ft), 12,000 meter (39,370 ft) and 15,000 meter (49,213 ft). these records were broken by from 19 percent to more than 30 percent.
Air Force claims for the new records must be verified by the Federal Aeronautique International (FAI) in Paris, France, before they become official. The National Aeronautics Association (NAA), the U.S. arm of the FAI, officiated during all test flights and will submit record data to FAI on behalf of the Air Force.
McDonnell Doughlas Company, St. Louis, Missouri, is the F-15 airframe manufacturer and Pratt and Whitney Company, East Hartford, Connecticut, makes the F-100, 25,000 pound thrust class turbofan engine.
The F-15 is the first Air Force operational fighter aircraft with a thrust to weight ratio greater than one, enabling it to accelerate even while in a vertical climb.
