No evidence of surface-to-surface missile deployment was noted. Note: TIU memorandum was prepared by the Direc- torate of Intelligence.

No evidence of surface-to-surface missile No unusual activity was apparent on any of the fields with the exception of the roofing over of alert aircraft revetments at Phuc Yen, Gia Lam, and Hoa Lac airfields. The purpose of this roofing is not clear, but it does not appear to be of sufficient strength to withstand a bomb blast. It could be in- tended as a weather covering for the alert aircraft and crews and may also serve to protect the revet- ments from CBU pellets. 4. The air order of battle as shown in the photography is quite close to current official estimates with the exception of MIG-21s, none of which were in evidence on this mission. F Unless all seven MIG-21s then estimated to be in country were under cover, there is no explanation of their whereabouts at the time of the mission. The MIG-15/17 tally of 21 aircraft on the DRV airfields and considered operational is very close to the official estimate, however, and the excess may be explained by the presence of UMIG-15 trainers which could be mistaken for MIG-15/17 fighters in an initial read-out.

The photography showed 108 of the more Cur- rent estimates place 25 to 30 SAM firing units in the DRV, 14 of which showed up on this mission. One of the 69 unoccupied sites appeared to have been c /The 25 remaining sites identified on the photography were not sufficiently clear to determine occupancy. 6. Bomb damage assessment of Hanoi Power Plant: The mission provided good coverage of the Hanoi Thermal Power Plant, which had been the target of five Walleye missiles. Two direct hits on the roof of the generator hall can be seen. The impact points of the other three missiles can- not be precisely determined, although some new damage is observable in the immediate vicinity of the plant. Assuming the,,two missiles exploded within the generator hall, it is probable that two turbine generators received at least some damage. 7. Transportation: The mission also provided coverage of much of the rail network in the northern part of the country, with the exception of the Kep-Thai Nguyen line. An initial scan of the film showed that the mission covered 18 bridges and 11 rail yards that are included on the CIA priority requirements list for bomb damage assess- ment. Current information on the status of the Hanoi railroad highway bridgesover the Red River and the Canal des Rapides and serviceable by- passes was also obtained. 8. Chinese activity in North Vietnam: Two new storage areas with 42 dispersed buildings were identified at Lao Cai, showing that the Chinese engineers there are continuing to expand their con- struction activities.
