First Convair MX-774 (RTV-A-2) test rocket was successfully launched, first demonstrating use of gimballed engines and design features later incorporated in the Atlas ICBM. This was the first of three Convair-sponsored test flights. References: 17 .

Council of Soviet Ministers (SM) Decree 'On adoption of the R-11 into armaments' was issued. References: 474 .

Following a protracted two-year test series, the design was finally accepted for military service on 13 July 1955. In anticipation of this formal decree, in June of 1955 Makeyev was made Chief Designer at SKB-385, responsible for engineering of the R-11 and future small land and sea based ballistic missiles. SKB-385 was given complete responsibility for development of the sub-launched R-11FM in August 1955.

The supersonic intercontinental cruise missile was made obsolete by the Atlas ICBM. Already-built Navaho G-26 test missiles were flown to the end of 1958. At the time the program was cancelled full-range G-38 missiles were in fabrication with first flight test planned by the end of 1958. The engines, missile frame manufacturing techniques, inertial and stellar navigation equipment, and telemetry/guidance techniques developed for Navaho established the technical basis for all subsequent US rocket developments.

Cruise stage tanks 1 and 4 empty. The flight lasted only to T+96 seconds. At this point, duirng fseparation of the boost and cruise stages the vehicle became unstable and was unable to achieve level powered cruise flight.

Unmanned soil return mission launched coincident with Apollo 11 mission in last ditch attempt to return lunar soil to earth before United States. After completing 86 communications sessions and 52 orbits of the Moon at various inclinations and altitudes, crashed on the moon on 20 July in an attempted landing. Altitude data used in programming inaccurate or guidance system unable to cope with effect of lunar mascons.
