Yuri Gagarin was a Soviet science flagship. Was built in Leningrad in 1971. It’s 231 m long, and 32 m wide. Main engine has 14 000 kWt power. The crew is 136 people and also 220 scientists can travel and do their work. It has 1250 rooms, including 86 science labs. It was built to be able to communicate via satellites with all top important things in Russia. It had served variety of tasks. Most mind blowing is to come to Pacific and track Soviet missiles that were fired from USSR to the middle of nowhere in Pacific. Also to support communication with Soviet space objects – MIR station, Soyuz spaceships etc., when the coverage from on ground stations is poor it could go to any place in ocean and stay there linking Earth with space. It has 75 antennas, including two huge 25 m sat dishes. It could support itself autonomously in ocean for over than 120 days. Main Ocean was the Atlantic Ocean. Let’s see more:
There was a huge group of such space vessels. They were called “Space Fleet”. They were used to support anti missile strike against Soviet Union by communicating with satelites and detecting any possible threat from any point of the world. Also were used for civil works like MIR station.
In 1960s Soviet Union fired many ballistic missiles right in the middle of the Pacific Ocean. Then four ships like this but smaller were there around and tracked everything how the missiles flew, how they landed etc. For the secrecy purposes it was called a “Pacific Hydrographic Expedition.”
