This modification, made for Cosmonautics Day (it's called "For Cosmonautics Day" ), adds a rocket to a military base in the desert. You can't fly it, but it looks impressive and fits into the game.
Cosmonautics Day is celebrated on April 12. It was on April 12, 1961 that the Soviet cosmonaut Yu. A. Gagarin made the first orbital flight around the planet Earth, this was the first manned flight into space.
P.S. A pre-light of the model has been made, that is, it is illuminated differently at different times of the day. The installation is automatic.
