Question

What is the highest Mach jet that was created and works? What is the name and Mach?

Answer 1

Actually, Joe is wrong and Paul is right.  

The SR 71 is the fastest jet plane ever, which is what the question was.  

X-15 is a rocket plane.  

Fastest plane ever is the X-43 at Mach 9.8, but it was unmanned.

Answer 2

The fastest winged manned vehicle ever flown other than the Space Suttle was the X15. On October 3, 1967, Pete Knight of the U.S. Air Force flew the experimental rocket plane to mach 6.70 or 4,519 MPH on flight 188 of the series.

Answer 3

The Lockheed SR-71 is an advanced, long-range, Mach 3 strategic reconnaissance aircraft developed from the Lockheed YF-12A and A-12 aircraft by the Lockheed Skunk Works. The SR-71 was unofficially named the Blackbird. A defensive feature of the aircraft was its high speed and operating altitude, whereby, if a surface-to-air missile launch were detected, standard evasive action was simply to accelerate.

Maximum speed: Mach 3.2+ (2,200+ mph, 3530+ km/h) at 80,000 ft (24,000 m)

On 28 July 1976, an SR-71 broke the world record for its class: an absolute speed record of 1905.80993 knots (2,193.1669 mph, 3,529.56 km/h), and an "absolute altitude record" of 85,068.997 feet (25,929 m). Several airplanes exceeded this altitude in zoom climbs but not in sustained flight.

Answer 4

Guess if we're talking manned, that would make it Apollo.

Answer 5

Paul is wrong The fastest was the x-15 though never produced en masse it was still the fastest.

Answer 6

ok well the question isnt a good one..... highest mach jet??.... well the definition of a jet is "a reaction engine that discharges a fast moving jet of fluid to generate thrust in accordance with Newton's third law of motion." (wiki) so.... that does include liquid fueled rockets..... so it depends on what the question is in relation to..... are you talking about exactly???? I mean if you were talking about actual turbojet engines then from my understanding the MiG-25 Foxbat takes the speed record easily at MACH 3.5.... if you are talking about scramjet or ramjet engines then the X-43 is the fastest... if your talking about Rockets then obviously the space shuttle or saturn 5 Rocket or any spacecraft for that matter.... they reach Mach 33 I believe off hand..... it just depends on what ur talking exactly about...... I mean u can't compair a civic to a dragster... a civic is a economic passenger car with 4 cylinders made for fuel millage and a dragster is a streight line Race car with 8 cylinders made for extreme power....  see what I mean....

Answer 7

Actually,they're both wrong, since the fastest jet was the X-43A, the third flight, on Novermber 16, 2004, reached approximately Mach 10.

The X-43A is a scramjet, not a rocket plane, and hence uses a jet engine.

Answer 8

Known...SR-21 Blackbird     Mach 3.3    

Known.....MIG-25     Mach 3.2  

Possible..... Aurora spyplane Mach 6?

Answer 9

I imagine the answer to that question is classified.  Mach 3 is listed but I know that there are aircraft capable of at least Mach 4.

Answer 10

The fastest jet that was produced and flown operationally was the SR-71, which flew at mach 3+. Other aircraft like the X-15 and X-43 have gone faster but ,as expiremental test vehicles, were very limited in what they could do. For instance, the X-15 was rocket powered and launched from a bomber which really limited it to testing, which is what it was designed for. The X-43 scamjet was similiarly launched from a bomber, unmanned, and flew in essentially straight lines simply to test scramjet engine technology. The SR-71 surpasses x-planes and such as it is completely operational. In fact, it's decended from concepts for mach 3 interceptors and attack aircraft, so it was a very well developed design.

The SR-71 had a top speed of 2200 mph or mach 3.2. There is supposedly some unreleased material on the Blackbird's performance and suggestions that it flew faster, but these claims are impossible to confirm without more info. An interesting fact is also that the SR-71 operated at an altitude of around 80,000 feet. In fact, anything operating at higher speeds of mach 6 and above like the fabled "Aurora" would do so at altitudes of 100,000 feet or more. With such high altitudes, it's likeley that we're not talking about an aircraft, but a spaceplane. This gray area between definitions of aircraft and spacecraft will likely make the SR-71 the fastest pure airplane ever.
