Can anyone tell me the ACTUAL top speed (not OFFICIAL) for the Lockheed SR-71 blackbird ?


.Can anyone tell me the ACTUAL top speed (not OFFICIAL) for the Lockheed SR-71 blackbird ?
I have only heard the official top speed no one has ever (that i know of ) give the Actual top speed. i know they go into the statosphere, and drip hydrogen. almost outerspace

10,000 miles an hour


27/28 July 1976: SR-71A sets speed and altitude records (Altitude in Horizontal Flight: 85,068.997 ft. and Speed Over a Straight Course: 2,193.167 mph).


All I know is that in 1983 the SR-71 flew from Ramstein Airforce Base in Germany to a gov’t air strip outside of San Francisco in just under 2 1/2 hours.


1500 MPH up 2900 down 2100 streightaway


I do not wish to tell where I worked. However, it was in the “midwest”. some years ago, a Blackbird came to our community because of our contract defense plant. The pilot was in the factory, talking to my brother. My brother asked him how fast it would go.

He of course responded that number was secret. He added that he would call my brother from the local airport, then when he got back to CA. The time betwen those calls was VERY SHORT!

I am guessing he could not go full speed due to sonic boom damage if he did.


That is one part of the SR-71 that is still classified. Released info says says so high, so fast, but does not limit the figures to what are released. When they were decommissioned one took off from Edwards AFB, went out over the Pacific, refueled at altitude, started time over LAX and landed at Washington National 64 minutes later.

i flew one back in the war and i know for a fact they can hit 28,000 Megatrillion Knots per second….i outran the Mellenium Falcon and he was in hyperspeed!!!


You are correct, the actual top speed, or max altitude for the matter, has not been disclosed. It may never come out, who knows, but it will probably be close to mach 4, and 100,000 ft.

Just to give you an idea of how fast it flew when it set the record, if you shot a 30.06 rifle and could keep the bullet at that velocity, the SR71 would beat it. This was a favorite explanation from a pilot in AIr Force magazine.

The actual top speed has not been reliesed to the public yet. It is somewhere in the Mach 3 region, but there is no exact disclosed number, so there is no answer to your question yet.


Classified. You’re going to jail for even asking.
