Soyuz 11A511 launch vehicle

Soyuz 11A511 was the original three-stage launch-vehicle variant developed to carry early Soyuz spacecraft. It began flight testing with uncrewed Soyuz missions in 1966, launched the first crewed Soyuz flight in 1967, and served crewed and uncrewed missions through the mid-1970s before the standardized Soyuz-U superseded it.
