(TSR) This report describes significant activity at Petrovka Naval Base and Shipyard, USSR, from December 1976 through April 1978. The earliest imagery in this time period was obtained on This report updates NPIC reportated May 1977. 2. (TSR) Significant activity includes the fitting-out'of D-I nuclear-powered ballistic mis- sile submarines (SSBNs), the maintenance/overhaul of Y SSBNs and V-I nuclear-powered at- tack submarines (SSNs), and the overhaul/modification of E-II cruise missile submarines (SSGNs) and Z attack submarines (SSs). Facility changes during this reporting period included the completion of a repair hall, the identification of a second repair hall under construction, and the construction of an engineering/light fabrication building, an administration building with storage wings, and two civil defense areas. 3. (TSR) This report contains four annotated photographs and an order-of-battle table by reporting position of combatants and selected auxiliaries. Also included is an updated layout of the shipyard showing the order=of-battle reporting position and a functional area analysis. Status/Activity 4. (TSR) The first repair hall (Figures 1 and 2), designated repair hall 1, was externally complete by early 1976 and was operational by when a Y SSBN was placed inside the hall, probably on the north set of rails. The new transverser, completed in October 1976,1 was used for the first time during the transfer of this Y SSBN to the repair hall. 5. (TSR) Between a large portion of the upper door track and supports on the north side of repair hall 1 were removed, probably to facilitate the emplacement of the uprights for construction of repair hall 2 since space between the two halls was limited. The removal of the sections and the presence of a security fence around the construction area of repair hall 2 preclude sliding the doors of repair hall 1 to the north during the current stage of construction. six pairs of uprights had been emplaced. The dimensions of this new building are Although this building is shorter than repair hall 1, it can accommo- date all vessels, capable of fitting into the basin (i.e., through the D-I SSBN). Footings being constructed between the north uprights of repair hall 2 and the adjacent steamlines indicate that an administration wing may also be added to this hall.-The rail systems in front of the two repair halls are not, the same. Repair hall 1 has three four-rail sets with 6-meter spacing. The sets are 2 meters apart.' Repair hall 2 has a centerline set of rails with 6-meter spacing, but the sets on either side of the center set consist of 11 rails each (Figure 3). These cover a distance of 10"meters on either side of the center rails. However, the distance between any group of seven rails will provide a 6-meter spacing. The inner rails of the two outer rail sets are 2 meters from the center set, and there is a 5-meter clearance, between the outermost rails and the building uprights. This building will probably be able to hold three submarines simultaneously. 6. (TSR) Dismantlement of the old transverser carriage had begun byl and it was almost complete by0 Even though the trackage for the transverser extension is double that of the original, the new transverser carriage is able to transit between the two. This double trackage was probably necessary to accommodate the weight of an SSBN entering the repair hall. 7.

(TSR) Construction continued on the administration-type building and two attached sheds/warehouses adjacent to reporting position (RP) 23. The administration-type building is four stories high and is The shed/warehouse extensions are 9. (TSR) A new civil defense area, designated area 1 (Figures 1 and 2), is under construc- tion north of the shipyard. It contains a probable engineering building with a light fabrication/ shop wing. The engineering building is The light fabrication/ shop wing is A basement shelter was constructed under the engineering section of the building, and an additional subsurface personnel shelter is being constructed north of the building. Heating lines are being installed which seem to tie this building to the base. Another new civil defense area, designated area 2, is northwest of the shipyard. Its proximity to the base may indicate an association between the two. Delta-Class SSBN 10. (TSR) The launching of D-I SSBNs at Komsomolsk Shipyard Amur 199 the fall of 1977.

(TSR) Six Y-class SSBNs were in various stages of overhaul/repair during this report- ing period; three of these were completed.

(TSR) Between a Y SSBN arrived at RP 1. Between it either moved to RP 3 or left the yard. If this Y SSBN left the yard between the one at RP 3 on was a new arrival. The exact events are were in the reactor/machinery spaces. Between a work platform surrounded the opening. This unit is probably in the yard or a major overhaul. 18. (TSR) Although there was transverser carriage activity between early December 1977 and early January 1978 while the two Y SSBNs were on the shelf, it is unlikely that either unit went into or came out of the repair hall. Usually a unit is opened and decontaminated prior to major overhaul, which was not done with either of these units. Additionally, a unit usually goes into a covered repair facility if it is undergoing a major overhaul. The Y SSBN which went into the hall in May 1977 could not have completed an overhaul recore/refueling operation in that short a time frame. 19. (TSR) Overhaul/modification work continued on E-II SSGNs. Three E-II SSGNs were on the repairways through the E-II which had been at RP 15 was moved to RP 22, robably or post-overhaul workup. This submarine remained at RP 22 through On an E-II SSGN was observed at the degaussing area (RP 24) although RP 22 was cloud covered, this was probably the same submarine. By the submarine was being repositioned at RP 22 and had temporary covers over the blast deflectors (Figure 5) which are possibly used during degaussing. This submarine left Petrovka between The E-II SSGN at RP 14 remained there throughout the reporting period. By the missile tubes were being retrofitted. The third E-II SSGN was moved from RP 16 to HP 15 between Its sail had been removed, and overhaul/modification work was underway. 20. (TSR) Two V-I SSNs were present during the reporting period. The first one had arrived at RP 22 by The hull was opened in the area of the reactor and machinery spaces, and a work platform surrounded the opening. By the pressure hull appeared to have been closed, and the submarine left Petrovka between The second V-I SSN arrived at RP 5 by transfer dollies for this submarine were in position on the basin shelf, and by the submarine had been moved to the repairway at RP 16 where it remained during the rest of the reporting period. No major overhaul work was observed on this unit. 21. (TSR) Although N SSNs were present at various times, no obvious external work was performed on any of these during this reporting period. 22. (TSR) The I-class SSAG (auxiliary submarine formerly 199D, was in the ARD(T) at RP 1 from through0 By this unit was at the fitting-out pier, RP 3, with one submersible alongside. By it had departed the shipyard. The training device associated with the I SSAG remained on the quay at RP 4 through The trai bsequently seen at Vladivostok Submarine Base Ulisa Bay (BE 23. (TSR) The modification of Z-class SS to SSAG continued. The first unit remained at Petrovka throughout the reporting period and is presently outboard of the other Z SSAG at RP 20. The second unit, on which modification started in December 1975, had its bulbous bow removed in 1976. The pieces from the bow have remained in the yard behind the re airwa s. Training tower modifications to this Z SS continued through it had been launched and has continued its post-modification workup inboard of the first Z SSAG at RP 20. A Z-V SS (converted fleet ballistic missile submarine--SSB) arrived at Pe- trovka by the Z-V SS was being positioned in the basin, and by it was on the repairway at RP 13, where the two previous Z-class SSs had been modified. No modification work has begun on this unit. - 9': Top :Secret RCA-09/0019/78 'JSV1 25X1 25X1 25X1 ZW&I 25X1 'IG V I 25X1 25X1 25X1 25X1 25X1 25X1 25X1 25X1 25X1 ZW&I 25X1 Sanitized Copy Approved for Release 2010/03/03: CIA-RDP78B07179A000100370001-8 Top Secret RUFF Other Activity 24.
