What speed can the fastest jet in the world go?

Question

How fast is the fastest jet?

Answer 1

you also now have to include remote control winged aircraft, including missles.

Answer 2

SR-71 is the world record holder and fastest that we know of. There are reports of top secret government "black" projects being developed by Lockheed's Skunk Works that have prototype jets capable of speeds in excess of Mach 5 or 6 like the Aurora spy plane.

Answer 3

currently, even though the airplane is out of commission, the fastest jet powered aircraft is the SR 71 Blackbird, Built by Lockheed. with speeds of Mach 3.3 (or 3.3 times the speed of sound) it travels at an altitude of roughly 85,000 feet above sea level.

Answer 4

The fastest aircraft is the X-43 which reached a speed of Mach 9.8 with a max altitude of 110,000 feet. It is unmanned, flown by remote control and a NASA toy. The goal is to achieve Mach 10.

The fasted manned aircraft is the X-15 with a speed of Mach 6.72 with a max altitude of 354,200 feet.



The SR-71 is the fastest manned airplane with a publicly released speed of Mach 3.2+ and a max altitide of 85,000+ feet. It is the fastest pure airplane, followed closely by the Russian MIG 25 Foxbat, at Mach 3.2, with an altitude record of 123,000+ feet. The SR-71 can fly significantly faster then the publicly released speed of Mach 3.2.  Eventhough it is named the "Blackbird" the crews and maintenance guys nicknamed it "Habu" after the Asian snake.

Answer 5

Officially, the world's fastest jet-powered aircraft remains the SR-71 Blackbird. Although the official record is about Mach 3.3 (or 3.3 times the speed of sound), many believe the aircraft could actually fly much faster. However, it seems unlikely that the SR-71 could go much faster than about Mach 3.5, with a very slim chance of Mach 4, due to propulsion and structural limitations. By Mach 3.6 or 3.8, shock waves generated by the nose of the aircraft are formed at an angle such that they impact the engine nacelles and cause the engines to unstart. In addition, heat generated by the aircraft's high speed increases to the point that certain portions of the plane's structure begin to fail by about Mach 3.5.

Answer 6

Do you mean the fastest "jet" or the fastest airplane?  The fastest airplane ever built was the X-15, which could actually climb above the earth's atmosphere, and flew faster than Mach 6.7, or about 4,520 MPH.

The fastest turbojet-powered airplane is considered the SR-71, and its top speed is still classified.  A prior answerer gave a really good read on the SR-71.
