• Country: United States
• Purpose: Long-range reconnaissance and intelligence gathering
• Notable Features:
  • Developed by Lockheed’s Skunk Works division in the 1960s, this aircraft became famous for its stealth and speed.
  • Built to evade enemy radar and missiles by flying at extreme speeds and altitudes.
  • Its titanium structure allowed it to withstand high temperatures caused by air friction at high speeds.
  • The SR-71 could travel from coast to coast in the United States in about 1 hour and 30 minutes.
• Engine: Pratt & Whitney J58 engines, uniquely designed to handle the extreme stresses of supersonic speeds.
• Status: Retired from the U.S. Air Force in 1998, although some aircraft have been retained for display and research purposes.

3. Mikoyan-Gurevich MiG-25 Foxbat

• Top Speed: Mach 3.2 (2,190 miles per hour or 3,524 km/h)
• Country: Soviet Union (now Russia)
• Purpose: Interceptor and reconnaissance
• Notable Features:
  • Designed in the 1960s to counter perceived threats from supersonic U.S. aircraft, especially the XB-70 Valkyrie.
  • Primarily used as a high-speed interceptor capable of intercepting enemy bombers and reconnaissance aircraft.
  • Limited operational range at top speed due to extreme fuel consumption and structural concerns.
  • Known for its twin-engine, twin-tail layout, and sturdy construction to withstand high speeds and altitudes.
• Engine: Twin Tumansky R-15B-300 engines.
• Status: Some variants still in limited use, but mostly retired.

4. Bell X-2 Starbuster

• Top Speed: Mach 3.196 (approximately 2,094 miles per hour or 3,370 km/h)
• Country: United States
• Purpose: High-speed and high-altitude research aircraft
• Notable Features:
  • Developed to explore aerodynamic challenges and control issues at altitudes above 100,000 feet.
  • It used a swept-wing design and rocket engine to reach altitudes beyond that of traditional jet engines.
  • Pilots encountered extreme difficulties controlling the aircraft at high speeds, eventually leading to crashes.
  • After the fatal accident of pilot Mel Apt, the X-2 program was halted.
• Engine: Reaction Motors XLR25 rocket engine.
• Status: Retired after testing phase.

5. XB-70 Valkyrie

• Top Speed: Mach 3.1 (2,056 miles per hour or 3,310 km/h)
• Country: United States
• Purpose: Strategic bomber prototype for high-speed penetration of enemy airspace
• Notable Features:
  • Developed by North American Aviation, this bomber was designed during the Cold War for the U.S. Air Force.
  • It used a unique wingtips-drooping design to improve stability at high speeds.
  • With a massive size and distinctive white color to reflect heat, it could fly at altitudes above 70,000 feet.
  • Eventually canceled due to advancements in anti-aircraft missiles that made high-speed bombers less viable.
• Engine: Six General Electric YJ93 engines.
• Status: Program canceled; only two prototypes were built.

• Purpose: Long-range interceptor
• Notable Features:
  • Developed as a successor to the MiG-25 Foxbat, with upgraded avionics and weapons systems.
  • Designed to intercept low-flying targets as well as high-speed bombers.
  • Retains the rugged, high-speed performance needed for intercepting hostile aircraft in remote, cold regions of Russia.
• Engine: Twin Soloviev D-30F6 engines, with powerful afterburners to maintain supersonic speeds over long distances.
• Status: Operational with the Russian Air Force.
