Why did the USSR not have reconnaissance aircraft like the United States

Soviet science and technology have never been an opponent of the United States. In the 50s, it was unthinkable to build a reconnaissance plane like the U2 that could fly stably at an altitude of 20,000 meters, and even today it would not be easy to fly at such an altitude for a long time with one engine, not to mention that the Soviets would never have advanced reconnaissance equipment like the United States. Not to mention SR71, which is still believed by many to be proof of Americans' use of alien technology.

The triple speed of sound of the MIG25 is the garbage in the garbage compared to the SR71, because the thrust of the MIG25 engine is very small, and its own body is very bulky, and the drag is very large, and it must be driven for a long time to slowly climb and accelerate to 3 times the speed of sound, not to mention how bad the flight performance is at this time, the average flight speed of a flight is just supersonic speed, and the SR71 can fly continuously for a long time of Mach 2 to 3, not to mention the speed world record created by the Blackbird in its first public appearance in 1976, Let's just say that the flight test from New York to London after the Blackbird 66 years of service, including in-flight refueling, is only 2 hours, with an average speed of nearly 3000 kilometers per hour, this is the really scary thing about SR71, flying faster than a bullet is definitely not chasing a bull, let alone a moment, but a speed that can be maintained for a long time. For this purpose, it is necessary to have a special variable cycle engine and a special aerodynamic design.

This is a matter of leaders, the Soviet leaders believe that on the European side, the Soviet Union deployed more than 20,000 advanced tanks and large-scale fighters, in the event of a war, the entire NATO side can be said to be unable to stop the Soviet army except for the use of nuclear **, in other aspects, the Soviet Union's missiles, navy and other armed forces can completely achieve superiority over the United States, especially the Soviet Union in Moscow also arranged 5 air defense circles, these military forces do not need any reconnaissance aircraft at all, the final result is that there is no development of reconnaissance aircraft! These are what I learned from an old Soviet engineer!

And the Soviet Union did not have a suitable airfield to reconnoiter the United States (only Cuba).

M 55 and MiG-25R, I don't know if these 2 count. The Soviets' principle was that enough is good.

The USSR maintained a powerful electronic reconnaissance ship.

The United States does not.

I understand that this kind of reconnaissance aircraft you are talking about is the American SR-71 Blackbird high-altitude and high-speed reconnaissance aircraft.

The Lockheed SR-71 reconnaissance aircraft (English: Lockheed SR-71, nickname: Blackbird, translation: Blackbird) is a jet long-range high-altitude and high-speed strategic reconnaissance aircraft used by the United States Air Force.

The SR-71 reconnaissance aircraft was developed and produced by the Skunk Factory of the American Lockheed Corporation, and adopted a large number of advanced technologies at the time, and was the first practical jet aircraft to successfully break through the thermal barrier. In the combat record, not a single SR-71 has ever been shot down by an enemy aircraft or an anti-aircraft missile. During its service, Blackbird repeatedly crossed the Iron Curtain to conduct high-altitude photographic reconnaissance of the Soviet Union, and obtained a large amount of confidential data from the Soviet Union, but the Soviet Union suffered from no corresponding counterattack and could not deal with it effectively!

A total of 71 SR-32 reconnaissance aircraft were produced. In 1990, the SR-71 was decommissioned; In 1995, part of the SR-71 was reorganized into the unit and flew in 1997. In 1998, the SR-71 was permanently retired and partially put on museum display, with the exception of one SR-71A and one SR-71B used by NASA's Dryden Flight Research Center for research use.
