This is National Intelligence Estimate 11-5-61, Soviet Technical Capabilities in Guided Missiles and Space Vehicles. It was submitted by the Director of Central Intelligence and concurred in by the United States Intelligence Board on 25 April 1961. The estimate assesses Soviet surface-to-air, antimissile, air-to-air, air-to-surface, ballistic, ICBM, naval and space programs. It concludes that the first Soviet ICBM unit was probably operational around 1 January 1960. It also says there is no evidence the Soviets are developing offensive space weapons. It contains no UFO material.
C00278407 23 Ground-Launched Cruise-Type Systems 97. Recent Soviet statements, as well as other information, indicates that the USSR has a current interest in long range cruise-type ve- hicles. We estimate that the Soviets are de- veloping' and could have available for opera- tional use in 1962-1963 a ground-launched, ramjet-propelled vehicle, with a speed of about Mach 3, a cruise altitude of 65,000-70,000 feet, and a range in excess of 4,000 n_m. Vehicles of this type could be employed in a research role for investigation of structures and pro- pulsion systems in the Mach 3 region. How- ever, such a system could be employed for weapon delivery or reconnaissance, and would further complicate Western air defense prob- lems.
