Deployment of the R-5M in 1956 caused the Sixth Directorate of the Ministry of Military Forces of the USSR's First Military Subdivision, consisting of two brigades, to be formed. The need for a new arrangement for safeguarding nuclear weapons deployed with field units led to a decree replacing the Sixth Directorate with a Twelfth General Directorate of the Ministry of Defence, charged with the development, trials, deployment, and security of nuclear warheads.

North American informed MSC of a fire in the reaction control system (RCS) test cell during a CM RCS test for spacecraft 009. The fire was suspected to have been caused by overheating the test cell when the 10 engines were activated, approximately 30 sec prior to test completion. An estimated test delay of two to three weeks, due to shutdown of the test cell for refurbishment, was forecast. MSC informed the Apollo Program Director that an investigation was underway.

Unmanned test of manned lunar mission launch vehicle serial number 7L. This article incorporated significant changes to the previous model, including roll control 'steering' engines to prevent the loss of control that destroyed 6L. The rocket ascended into the sky, and the engines ran 106.93 seconds, only seven seconds before completion of first stage burnout. Programmed shutdown of some engines to prevent overstressing of the structure led to propellant line hammering, rupture of propellant lines, and an explosion of engine number 4. The vehicle was destroyed by range safety. References: 5 .
