Q: What was the L-3 program?

A: L-3 was the Soviet lunar spacecraft program that included both a command module (Soyuz 7K-LOK) and a lunar lander (LK). It was designed to support crewed missions to the Moon but was cancelled in 1974 along with the N1 launch vehicle program.

Q: Why was the L-3 program cancelled?

A: The L-3 program was cancelled in 1974 due to the failure of the N1 super heavy-lift launch vehicle, which was essential for launching the spacecraft to the Moon. The Soviet Union decided to abandon its crewed lunar program after multiple N1 launch failures.

Q: What spacecraft were part of the L-3 program?

A: The L-3 program consisted of two main spacecraft: the Soyuz 7K-LOK command module, which would carry two cosmonauts to lunar orbit, and the LK lunar lander, which would carry one cosmonaut to the Moon's surface.
