Faster than the speed of sound???

Since the creation of the first model in 1909 (The U.S. Army Signal Corps purchased a Wright Model A) , military aviation is rapidly progressing. Incremental improvements are made in many areas, especially powerplants, aerodynamics, structures, weapons, electronic warfare, weather reconnaissance, flying lifeboats….
Today we’re witnessing that some of these planes may be faster than sound.
Here are, some of the fastest military planes of today (some of them are still experimental) :

1. North American X-15
The North American X-15 was a hypersonic rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. It could reach a top speed of 4,520 miles per hour (7,274 km/h), or Mach 6.72












2. Lockheed SR-71 Blackbird
The Lockheed SR-71 “Blackbird” is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. Maximum speed mach 3.3 (2,200+ mph, 3,540+ km/h, 1,910+ knots)640px-lockheed_sr-71














3. Lockheed YF-12
The Lockheed YF-12 was an American prototype interceptor aircraft evaluated by the United States Air Force. The YF-12 was a twin-seat version of the secret single-seat Lockheed A-12 reconnaissance aircraftThe YF-12 set and held speed and altitude world records of over 2,000 mph and over 80,000 ft (later surpassed by the SR-71), and is the world’s largest manned interceptor to date

















4. Mikoyan-Gurevich MiG-25
The Mikoyan-Gurevich MiG-25 (Russian: Микоян и Гуревич МиГ-25) (NATO reporting name: Foxbat) is a supersonic interceptor and reconnaissance aircraft that was among the fastest military aircraft to enter service. It has an operational top speed of Mach 2.83 (Mach 3.2 is possible but at risk of significant damage to the engines), and features a powerful radar and four air-to-air missiles.












5. Bell X-2
The X-2 was a rocket-powered, swept-wing research aircraft developed jointly in 1945 by Bell Aircraft Corporation, the U.S. Air Force and the National Advisory Committee for Aeronautics (NACA) to explore aerodynamic problems of supersonic flight and to expand the speed and altitude regimes obtained with the earlier X-1 series of research aircraft. Maximum speed: Mach 3.196 (2,094 mph, 3,370 km/h)











6. North American XB-70 Valkyrie

The North American Aviation XB-70 Valkyrie is the prototype of the B-70 nuclear-armed, deep-penetration strategic bomber for the U.S. Air Force’s Strategic Air Command. In the late 1950s North American Aviation designed the Valkyrie bomber as a large, six-engined aircraft capable of reaching Mach 3+ while flying at 70,000 feet (21,000 m).













7. Mikoyan MiG-31
The Mikoyan MiG-31 (Russian: Микоян МиГ-31; NATO reporting name: Foxhound) is a supersonic interceptor aircraft developed for use by the Soviet Air Forces. The aircraft was designed by the Mikoyan design bureau as a replacement for the earlier MiG-25 “Foxbat”; the MiG-31 is based on, and shares design elements with the MiG-25. The MiG-31 has the distinction of being one of the fastest combat jets in the world. Maximum speed Mach 2.83 (3,000 km/h, 1,860 mp)













8. McDonnell Douglas F-15 Eagle

The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather tactical fighter aircraft designed by McDonnell Douglas (now Boeing) to gain and maintain air supremacy in aerial combat. Maximum speed Mach 2.5+ (1,650+ mph, 2,665+ km/h)











9. General Dynamics F-111 Aardvark
The General Dynamics F-111 Aardvark was a supersonic, medium-range interdictor and tactical attack aircraft that also filled the roles of strategic nuclear bomber, aerial reconnaissance, and electronic-warfare aircraft in its various versions. Maximum speed Mach 2.5 (1,650 mph, 2,655 km/h)











10. Sukhoi Su-27

The Sukhoi Su-27 (Russian: Сухой Су-27) (NATO reporting name: Flanker) is a twin-engine supermaneuverable fighter aircraft designed by Sukhoi. It was intended as a direct competitor for the large United States fourth-generation fighters such as the Grumman F-14 Tomcat and F-15 Eagle, with 3,530-kilometre (1,910 nmi) range, heavy aircraft ordnance, sophisticated avionics and high maneuverability. The Su-27 was designed for air superiority missions, and subsequent variants are able to perform almost all aerial warfare operations. It was designed with the Mikoyan MiG-29 as its complement (The role of the MiG-29 is tactical air superiority over the battlefield, engaging NATO fighters and strike aircraft). Maximum speed Mach 2.35 (2,500 km/h, 1,550 mph)















Sukhoi 5th generation fighter jet PAK-FA (T-50)


Five PAK-FAs have been produced and three more are now being constructed at the Sukhoi Aviation Holding Company Y.A.Gagarin in Komsomolsk-on-Amur (KnAAZ).Sophisticated equipment, stealth technology, super maneuverability, weapons,…placing T-50 or PAK-FA fighter jet to 5th generation fighter jet class. Someone saying this is a copy of American project and serial produced F-35 or F-22, but we just can guess this is final project of many years experience and knowledge in OKB Sukhoi corporation, which tracking military trends and requests to stay in aviation and technological race, side by side with possible opponents.

pak-faSimilar to F-22, Sukhoi PAK-FA should be able to cruise supersonically for extended periods of time. PAK-FA is powered by highly upgraded AL-31F engines that powers the Su-35S and initial production PAK FA aircraft. , and received code name Izdeliye 117 or AL-41F1, made for supercruise. It is also notable that the engine is capable of mounting 3D thrust vectoring nozzles for extra manoeuvrability.

PAK-FA is also equipped with a powerful avionics package, which is an evolution of Sukhoi’s work on the Flanker family fighters, like Su-35.There is very high power-aperture X-band multimode AESA radar.

t-50-055_01_hiresPAK-FA is still testing and for sure will have some changes, modifications. Developing by two sides, India and Russia, we will have two users in start. The Russian Air Force (VVS) will have received 55 Sukhoi PAK-FA (T-50) fighter aircraft by 2020.India planned on acquiring modified PAK FA as a part of its Fifth Generation Fighter Aircraft (FGFA) program. It originally planned on buying 166 single-seat and 44 two-seat variants, but this has since been reduced to 144 single-seat aircraft due to cost.



The aircraft is expected to have a service life of up to 35 years.
