Kosmos 111 (Russian: Космос 111 meaning Cosmos 111) (E-6S series) was the first Soviet attempt to orbit a spacecraft around the Moon. The design was probably similar to the later successful Luna 10 spacecraft. Kosmos 111 was produced in less than a month, one of two spacecraft developed from the E-6 lander bus in a crash program to upstage America's Lunar Orbiter series and to commemorate the 23rd Congress of the Communist Party (held March 1966)..
Luna 10 spacecraft. Kosmos 111 was probably similar in design.

Launched on March 1, 1966 at 11:03:49 UTC via Molniya 8K78M rocket from 31/6 (COSPAR_ID: 1966-017A, SATCAT: 2093)(, the mission was a failure. The Blok-L upper stage lost roll control and failed to send the spacecraft on a lunar trajectory. It re-entered the Earth's atmosphere two days later. The craft weighed 14,240lbs and was not immediately acknowledged to be a Luna-series vehicle after its destruction.
