Top 5 fastest aircraft in the world

5. XB 70 "valkyre"

This is the fastest bomber ever produce. and its the only bomber can reach mach 3. It had maximum speed over 3.1 mach. its speed comes from  6x General Electric YJ93-GE-3 afterburning turbojet. each of the engine produce thrust over 28,800 lbf (128 kN) each engine, So the total thrust of the engine is about 768kn wow its so huge..


4. MIG 25 "foxbat"
This is the fastest Russian interceptor. its maximum speed reaching over 3000km/h. Its intended to intercept america fastest Spy plane known as SR - 71 blackbird & XB 70 valkyre, the only mach 3 bomber in the world. Mig 25 foxbat carry 2 R - 40 a long range air to air missile . And the engine of this aircraft is fascinating it had 2  Tumansky R-15B - 300 afterburning turbojets. It's mighty engine produce over 100.1 kN (22,494 lbf) each engine. And when the western first known the Foxbat they are terified by its speed at turbo jets.


3. Lockheed SR - 71"blackbird"
This is the fastest US spy plane, its maximum speed reaching about  3,530km/h. US designed this plane because  they really need fast, strong , powerful spy plane. And it had a tactical advantage over the soviet plane. Because the only plane that can intercept this fascinating spy plane only MIG 25 foxbat & MIG 31 foxhound. The power came from its 2   Pratt & Whitney J58-1 continuous-bleed after burning turbojets. its produce thrust over 34,000 lbf (151 kN) each. So this is one of the finest revolutionary plane because when this plane was produced. Its the first plane that can reach Mach 3. 


2.X - 15
This is the fastest maned aircraft ever built. It had a maximum speed of 6,72 mach. it speeds comes from Thiokol XLR99-RM-2 liquid fuel rocket engine.. T his plane is intended for only experiment plane, and to break the world air speed record. 


1.X - 43
This is the fastest UAV in the world.  it had a maximum speed over 9,8 mach. its power comes from its revolutionary Ramjet. ramjet is a form of airbreathing jet engine using the engine's forward motion to compress incoming air, without a rotary compressor. And ramjet connot move the plane that stand still in the ground. So this plane lauch from the belly of huge B - 52 Stratofortress.
