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 TOP SECRET 24 VI. ICBM DEVELOPMENT PROGRAM 98. We have relatively firm evidence on the Soviet ICBM test range and the test-firing program, from which we have been able to de- rive basic characteristics of the ICBM vehicle, its propulsion, nosecone, and guidance system, as well as some of the ground support and logistic requirements for its operational de- ployment. From these data, we can also de- rive, though with some probable margin of error, some of the basic factors affecting So- viet ICBM performance under operational con- ditions, including general ranges, accuracy, and reliability. Finally, these data can be combined with other evidence to provide a sense of the tempo of the ICBM development program and the degree of success the USSR has achieved. However, the sum of our infor- mation is inconclusive as to the precise 'tim- ing of the initial ICBM deployment, and as to the scale and pace of the operational de- ployment program. While a full examination of the evidence and factors pertinent to the deployment program is reserved for a forth- coming estimate, it is necessary for the pres- ent analysis to include brief discussion of some of these matters. Tyuratam Missile Test Range 99. All Soviet ICBMs and space vehicles have been launched from a rangehead near Tyura- tarn, east of the Aral Sea (see Figure 27). The test range extends generally to the northeast approximately 3,500 n.m. to an instrumented impact area near Klyuchi on the Kamchatka Peninsula (see Figure 1). On several occa- sions, in connection with certain ICBM and space launchings, the range has been extended up to 6,700 n.m. into the Pacific Ocean through the use of' four Sibir-class instrumentation ships. 100. The Tyuratam test range has exten- sive communications, control, instrumenta- tion, and logistic facilities, which are sufficient to support ICBM and space operations of con- siderably greater intensity than those which have been conducted so far. On the basis of successive photographic coverage and other evidence, three launching areas are believed to be completed: - a. In 1955-1957, when the range was first established, the Soviets installed a single, massive launch pad over the edge of a huge pit. This is termed launch area "A" by US intelligence (see Figure 28). It was used for all ICBM and space launchings from Tyu- ratam at least through 1959 and possibly through 1960. b. In 1958, the Soviets began construction of a pad closely resembling the first launch area, known as area "B." It was probably ready for use in about mid-1960. c. In 1959, they began work on a pair of simplified pads without pits, known as launch area "C" (see Figure 29). Launch area "C" was probably completed in late 1960 or early 1961. 101. The evidence from Tyuratam indicates that the Soviet ICBM system is heavily de- pendent on rail support. Missiles destined for launch areas "A" and "B" are delivered by rail to nearby rail drive-through buildings where extensive checkout and prelaunch as- sembly operations are performed. Missiles are then transported directly to the launch pad_ by rail, and there is evidence to suggest that propellants as well as much of the support equipment necessary to a firing are also brought to the pad in this way. Relatively little time appears to be required on the pad. On one occasion, when only one pad was com- pleted, two missiles were launched in less than three days. Launch area "C" was photo- graphed while under construction, and its final configuration is not definitely estab- lished. It also has rail-served checkout build- ings nearby. Although a rail spur enters the pad area, it appears that missiles are to be transported from checkout buildings to pads by road. Launch sites of this type would necessarily be near rail lines, but a greater degree of flexibility, dispersal, and conceal- ment could probably be achieved. ICBM Test Firings 102. The first successful flight test in the So- viet ICBM development program occurred in August 1957, with the firing of a missile from
