World's ten fastest jet aircrafts

The jet aircraft engine was invented by Frank Whittle, an English inventor and RAF officer, in 1928. Later Hans von Ohain of Germany developed the concept independently at the end of the 1930s.These aircraft fly much faster than propeller-powered aircraft and at higher altitudes – as high as 10,000–15,000 metres. At these altitudes.The engines in propeller-powered aircraft achieve their maximum efficiency at much lower altitudes. Some jet aircraft can move faster than sound.Here we present a list of world's fastest air jets: 1. XB-70 Valkyrie:This aircraft had a speed of 3.1 Mach and was in use for 5 yrs. It took its first flight on 21 September 1964 and was used last on 4 Feb 1969. This aircraft was used as a strategic bomber as well as a supersonic research aircraft. It has a range of 3.725 nmi on combat mission. It has a service ceiling of 77350 ft. Its primary users were US air force and NASA.2. MIG 25 Foxbat:This is a supersonic aircraft which was used as an interceptor and reconnaissance aircraft. It has a speed of 3.2 Mach. It took its first flight in 1964 and was introduced in 1970. There were a total number of 1186 aircrafts built till date. 3. Space Shuttle:This spacecraft is an orbital spacecraft which was designed by the US National Aeronautics and Space Administration for human spaceflight missions. It took its first flight on April 12, 1981 and its last flight took place on July 21, 2011. It can achieve up to a speed of 20 Mach. It has 2 boosters. 4. Tupolev Tu- 144:This aircraft was the fastest commercial airliner of the world that has ever been on earth. This was the world's first ever supersonic jet aircraft. It used to have a speed of 2.35 Mach which is equivalent to 1550 mph. This aircraft was last seen in 1978 after which it was no longer used for services.5. F 15 Eagle: Manufactured by McDonnell Douglas, this aircraft is very successful in the present times. It is a twin-engine aircraft used to fight tactically in each kind of weather. It has won around 100 aerial combats without losing any. The speed of this aircraft is 2.5 Mach. It took its first flight in 1972 and was introduced to everyone in 1976.6. Bell X2 Star buster:This aircraft took its first flight on 18 November 1955 and was only used till 27 September 1956. It can go up to a speed of 3.1 Mach. It has a service ceiling of 126200 ft. and was used as a research aircraft.7. MIG 31 ‘Foxhound':This aircraft was developed by Mikoyan to replace the MIG 25. It has a speed of 2.83 Mach at high altitudes and a speed of 1.2 Mach at lower altitudes. It has a rate of climbing of 208m/s. It has a ferry radius of 3300 km. 8. SR-71 Blackbird:It took its first flight in 1964 and after a providing a service of 4 decades retired in 1998 and was used for Strategic reconnaissance aircraft. It had a speed of 3.5 Mach. It was developed by the Lockheed Skunk Works. It has a range of 5400 kms and a service ceiling of 85000 ft. 9. X-15:This aircraft was built in 1959 by North American Aviation and it retired in 1970. It was used as an experimental high speed research aircraft. This aircraft was used by Neil Armstrong and many other famouos names. This can attain a maximum speed of 6.72 Mach. It has a service ceiling of 354,330 ft.10. X 43 A:The X-43 is an unmanned experimental hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of NASA's Hyper-X program and has set several airspeed records for jet-propelled aircraft. The X-43 is the fastest aircraft on record at over 6,500 miles per hour
