The SR71 was built in the early 70's. What new planes is the airforce using today that following the SR71 in terms of supersonic technological advancement ?
the SR-71 wa developed in the 50's and buit in the early 60's
maiden flight Dec, 22 1964
as for the answer your looking for
look it up
it has been answered 1,000 times already on answers.
the SR-71 blackbird still has the speed record. There is just no need for anything that goes faster these days. The job that the blackbird was designed for can now be done with satellites.
broke mock 3.8
They have yet to retest
because we are spending
all our money on war.
SR-71 still the fastest........they supposed to have a plane called Auroua now that is faster but they wont admit to its exsistance
I'm sure it's something the government is keeping quiet about.
Im just not sure anymore, but I do know that "mock" 3.8 is pretty stinkin fast, based on the "mock" scale that is.
The Aurora, while still not officially acknowledged, has already been retired and was supposed to be able to travel at around Mach 7 (based on a series of "earthquakes" which criss-crossed the U.S. in the 90's).
They continue to work on the quest for speed, but without stealth, there is little interest in it in a military sense. The law of "if you can see it, you can kill it" is still too close to the truth.
They tried out the X-43A in march 2004, check the book of world records.
To the best of my knowledge, it's the X-15. It was rocket powered but flew back in the 50's or early 60's at a record of 4360 mph. I wouldn't be surprised if there's something else out there now that we don't know about.
