376. Supplement 4 to Joint Evaluation prepared by Guided Missile and Astronautics Intelligence Committee, Joint Atomic Energy Intelligence Committee, and National Photographic Interpretation Center, October 241
NOTICE
This supplement updates and amplifies previous reports. Emphasis continues to be placed on the READINESS status of the offensive missiles in Cuba. This report is based on U–2 photographic coverage through Mission 3119 of 22 October 1962 (see Figure 1). Some of Mission 5002, the low altitude photographic coverage of 23 October 1962, arrived during the preparation of this report and preliminary comments have been incorporated in the discussion of the Guanajay IRBM sites. Analysis has just started and will require many hours for completion.
SUMMARY
1. There are two changes in the estimated dates of full operational capability. San Cristobal MRBM Site 2 and Sagua La Grande MRBM Site 1 are now estimated to achieve this status on 25 October instead of 22 October as previously estimated.
2. No new missile sites have been identified (See Table 1).
3. No IRBMs per se have yet been identified.
4. Seven Soviet ships with cargo hatch openings of 75 feet or longer have now been identified as possible ballistic missile carriers. They have made 13 trips to Cuba to date, and three are currently enroute to Cuba.
5. No new intelligence information has been received which modifies the nuclear storage situation.
