Soviet ship Kosmonavt Yuriy Gagarin
Kosmonavt Yuri Gagarin was not just a ship it was essentially a floating space communication control center of the USSR.
It was built in 1971 at the Baltic Shipyard in Leningrad, based on a cargo vessel hull, but its purpose was anything but civilian. Massive antenna systems, laboratories, and onboard computers were all designed for one mission: to maintain communication with spacecraft and cosmonauts when they were outside the range of ground stations. The ship received telemetry, transmitted commands, picked up voice communications, and even relayed television signals. Without vessels like this, the Soviet space program simply could not function properly.
It became the flagship of the Soviet space fleet, the largest and most advanced ship of its kind in the world. It supported the Soyuz, Salyut, Almaz, and Mir programs, operating in the Atlantic and Indian Oceans, standing watch where no land-based stations could receive a signal.
After the collapse of the USSR, everything went downhill. In 1991, the ship was transferred to Ukraine, but there was no funding to maintain it. The equipment became obsolete, space was no longer a priority, and in 1996 the legend was sold for scrap.
The irony is brutal: a ship that had maintained contact with orbit for decades did not perish in a storm or in service, but was lost to economic collapse and the breakdown of a system. Still, it remains a symbol of an era when the Soviet Union truly played in the top league of space exploration not in words, but in reality.

PS: I liked the idea of adding antenna control via the “weapons” system. At first, I planned to implement it through “elements,” but because they get detached from the ship, they would disappear. The “weapons” approach works perfectly.
