Developed by Lockheed’s Skunk Works division, the YF-12 showcased its prowess by intercepting targets at Mach 3.2 speeds and altitudes of 85,000 feet.
Armed with AIM-47 Falcon missiles, it demonstrated its firepower by downing a target at low altitude. The YF-12 program, while ultimately canceled due to cost concerns and changing priorities, yielded valuable technological advancements. Its legacy lives on in subsequent supersonic aircraft and contributed significantly to the advancement of aerodynamics and materials science.
Bell X-2 Starbuster
The Bell X-2, known as “Starbuster,” was a rocket-powered research aircraft designed to investigate aerodynamic heating effects, stability, and control at high speeds and altitudes.
Developed in 1945 through a collaboration between Bell Aircraft Corporation, the U.S. Air Force, and the National Advisory Committee for Aeronautics (NACA), it aimed to explore supersonic flight challenges beyond the X-1 series. Two X-2 airframes were constructed with stainless steel and K-monel, powered by a Curtiss-Wright XLR25 liquid-fueled rocket engine. On September 27, 1956, pilot Captain Milburn Apt set a record, exceeding three times the speed of sound at 2,094 mph (Mach 3.196), but a tragic turn caused a fatal control issue known as inertial coupling, resulting in his death, overshadowing the program’s achievements.
Mikoyan MiG-25 Foxbat
The Mikoyan MiG-25 Foxbat, a Soviet masterpiece, demonstrated its prowess as a high-speed interceptor. Its normal speed was 2.83 but it could reach a maximum speed of Mach 3.2.
As the Cold War’s opening years ushered in the era of intercontinental bombers, the Soviet Union needed a way to counter the U.S.’s formidable bombers. The result was the MiG-25, an aircraft that relied on brute force to catch its prey.
The MiG-25’s powerful engines were adapted from turbojets originally built for cruise missiles and reconnaissance drones. These engines, while enormous, had a short service life, and the aircraft had to withstand extreme kinetic heating during high-speed interceptions. To keep costs down and simplify maintenance, the MiG-25 was constructed primarily from heavy nickel-steel alloy rather than lightweight titanium.
This interceptor was equipped with a massive 600-kilowatt radar capable of detecting high-flying targets up to 100 kilometers away and defeating jamming devices. Its armament consisted of four of the largest air-to-air missiles ever produced. The Soviet Union mass-produced this aircraft, with 100 MiG-25s rolling off assembly lines each month at its peak.
The MiG-25, despite initial concerns, served primarily as an interceptor, not a dogfighter, and excelled in this role. It set numerous world records for speed and altitude, many of which remain unbroken. The aircraft’s legacy lies in its influence on the subsequent development of Soviet interceptors and air defense systems. The Soviet Union moved on to create the MiG-31, a more advanced interceptor that incorporated cutting-edge technology.
Mikoyan MiG-31 Foxhound
The Mikoyan MiG-31, also known as the “Foxhound” by NATO, is a supersonic interceptor aircraft developed as a replacement for the MiG-25 “Foxbat” by the Soviet Air Forces.
