The plane flew so fast that the missile could not catch up

After designer Clarence L aircraft . "Kelly" Johnson launched the Lockheed U-2 "Dragon Lady", knowing that this would be a good prey for the enemy's modern defense system, so he used all modern reconnaissance technologies. U-2 to create a more frightening thing: SR-71 "Blackbird" - the fastest fighter aircraft of all time.

Lockheed U-2 "Dragon Lady", the premise for the SR-71.

When SR-71 was commissioned in the United States Air Force, it demonstrated its ability to fly with incredible speed: 3.5 times the speed of sound and fly at a height of 26km. This height is three times greater than Mount Everest and pilots must wear protective equipment similar to astronauts to withstand the unbelievable pressure caused by altitude.

During the operation period, no SR-71 was destroyed by the enemy's bullet / missile. Even the surface-to-air missle (SAM) could not shoot down SR-71. However, it cannot be shot down because there is no radar detected in the sky, this is the first fighter to feature stealth. The entire body of the aircraft was covered with titanium because the surface temperature when traveling at very fast speeds, up to 500 degrees Celsius, and it was this titanium layer that made all radar waves absorbed, instead of reflecting on the ground. .

The surface-to-air missle (SAM) could not shoot down SR-71.

In addition, there is a system of modern electromagnetic interference that makes rocket launch from the ground or other aircraft disturbed, making it almost invincible.The MiG-25 , once one of the fastest and most powerful fighter in the world, could not defeat the SR-71.

MiG-25 aircraft.

It is worth mentioning that during the war, it was possible that the SR-71 was confronted with two MiG-25s, but the MiG-25 could not be relieved because the entire missile attack became useless at a height of 26km compared to On the ground, in addition to lower elevations, the missiles will not be able to catch up because of its unbelievably fast speed. And if the MiG-25 wants to fire the SR-71 missile in face-to-face position, the computer on the MiG-25 cannot lock the target.

The SR-71 pilot, Richard H. Graham, said in his book "SR-71 The Complete Illustrated History of THE BLACKBIRD The World's Highest, his Fastest Plane" : "Most land-to-air missiles cannot be activated. At an altitude of 9km above the ground, at an average height of 22.9km of the SR-71, ultra-thin air causes the flying speed of missiles to be affected, and most missiles strike unarmed. use ".
