412. Supplement 6 to Joint Evaluation prepared by Guided Missile and Astronautics Intelligence Committee, Joint Atomic Energy Intelligence Committee, and National Photographic Interpretation Center, October 261
This supplement updates and amplifies previous reports. Emphasis is placed on the READINESS status, construction pace and any significant changes at the offensive missile sites in Cuba. This report is based primarily on preliminary analysis of the 25 October low-altitude photography, portions of which arrived during the preparation of this report (see Figure 1).
1. The 25 October photography of four MRBM sites shows continued rapid construction activity at each site. This activity apparently continues to be directed toward achieving a full operational capability as soon as possible. Camouflage and canvas covering of critical equipment is also continuing. As yet there is no evidence indicating any intention to move or dismantle these sites.
2. There is one change in the estimated dates of operational capability. San Cristobal MRBM Site 2 is estimated to achieve a full operational capability on 26 October instead of 25 October, probably as a result of the heavy rain that has recently hit this site (see Figure 2).
3. No additional missiles, missile transporters, or erectors have been identified (see Table 1).
4. No new missile sites have been identified, although continued analysis of previous photography has revealed some road improvement activity in the Remedios area which is considered indicative of plans for the second IRBM site estimated for this area.
5. The three Soviet ships suspected of being possible ballistic missile carriers continue their eastward course towards the USSR.
