By full operational readiness we mean the ability to launch in salvo four missiles per site with a refire capability of four Missiles per site within 4 to 6 hours. Sagua La Grande Area 3. The MRBM sites at Sagua La Grande were first identified on 17 October and were covered by photography twice thatday. (The last previous coverage was on 7 July and showed no evidence of missile activity.) The status Of preparation at the two sites on 17 October was approximately the same. It is believed that the missile regiment was moving imto the area on 17 October, inasmuch as 35 vehicles arrived in a support area at Site 1 within the 1 3/4 hour period between two photographic coverages. 4. Construction activity and random location of missile support equip- ment indicate that development of the area was not complete. The presence of missiles and launchers indicates that the sites have an emergency operational capability. However, the regiment could reach full operational readiness at these sites by 1 November. Guanajay Area 5. A detailed reexamination of the evidence available at this time indicates that the operational date for these launch sites may be somewhat earlier than our previous estimate. Construction activity appears to be progressing at a more rapid pace than thatobserved in the USSR at similar facilities. Several features of the sites such as the control bunkers, excavations for fuel tanks, and blast walls for component protection are several days more advanced than previously determined. Mission 3111 on 18 October indicates that concrete is being instalied at all four pads at Site 1. 229
