ABSTRACT
1. (S/WN) This report describes significant activity observed at the Severodvinsk Shipyard
Complex, USSR, from 1 August through 31 December 1981, the information cutoff date. All
applicable satellite imagery of the complex acquired during this period was used in the prepara-
tion of this report.
2. (S/WN) Significant events that have occurred at this complex since the previous activity
report include the drydocking of the Typhoon SSBN, the rollout of D-III SSBN unit
14, the deployment of D-III SSBN unit 13 and the Oscar SSGN, and the dismantlement of two Y-I
SSBNs.
3. (S/WN) This report contains a layout of the Severodvinsk Shipyard Complex, 11 anno-
tated photographs, and a table of submarine activity. The layout of the complex shows the major
structures and reporting positions, and the table outlines the movement of all submarines at the
complex, with the exception of the inactive units at Naval Base West.
surfaces and propulsion system were concealed by four arched roof panels throughout the
drydocking period. Extensive work was ongoing in the areas of the stern, of the missile tubes, and
of the bow weapons-loading hatch. On numerous occasions while the submarine was in the
launch dock, tops of the personnel hoists/work platforms normally on the Typhoon fitting-out
quay could be seen inside the missile tubes of the submarine. Between the
Typhoon was removed from the launch dock and repositioned at RP 9, where it was undergoing
pretrials workup and probable onloading of SS-NX-20 ballast cans. The Typhoon was probably at
the quay on but had departed the complex by the
Typhoon had returned from sea trials and was at the calibration pier, where it was undergoing
deperming through OAfter additional underway-workup at RP 9 between
Typhoon was not observed at the complex on However, on
a submarine (most probably the Typhoon) was at the SLBM loading facility at Naval
Base West; on0an SS-NX-20 SLBM was launched from the White Seat (most
probably from the Typhoon SSBN).
6. (S/WN) On three probable SS-NX-20 ballast cans for the T hoon SSBN were
on the quay adjacent to the submarine. The probable ballast cans were in length and
in diameter. By the number of probable ballast cans had increased to five;
by to seven; and by to at least 17 (Figure 2). This increase coincided
with the movement of the Typhoon SSBN into the launch dock. On
the number of probable ballast cans could not be determined; however, on after
the departure of the Typhoon, the number of probable ballast cans had decreased to one. The
arrival of the probable ballast cans at the shipyard-coincidental with the drydocking of the
submarine for hull inspection/maintenance and the deperming of the Typhoon after its fourth
period of sea trials-was probably necessary for the ballasting of the submarine for the SS-NX-20
missile launch on
7. (S/WN) Numerous pieces of submarine components and plating were observed through-
out the reporting period. Components related to the Typhoon SSBN construction program which
were observed include the two- and four-hole internal missile bay deck plates and possible
Typhoon SSBN reactor plates. On Oa tapered pressure hull section was underneath
shed B in the pressure hull staging area behind construction hall 1. The pressure hull section was
positioned on its larger end, which was between 8 and 10 meters in diameter, and tapered to

D-III SSBN was at the shipyard for unidentified maintenance/repairs from 25X1
undergoing unidentified maintenance/repairs from through the remainder of the 2 X I
period.
Other Submarine Activity
11. (S/WN) Unidentified maintenance/repairs continued on the Oscar SSGN inside the
launch dock through at least the launch dock (with the Oscar 25X1
SSGN in its well) had been moved from its previous position in front of launch rail 1 of
construction hall 3. Heavy clouds and haze precluded the identification of the Oscar until 75X1
when the submarine was at the main fitting-out quay (Figure 5). OnFtwo 25X1
SS-NX-19 missile canisters and one probable SS-NX-19 crate were on railcars on the quay adjacent
to the Oscar (Figure 5). The aftermost starboard missile tube door on the Oscar was open, and a
crane was being operated over the submarine. Between the Oscar SSGN 25X1
departed the complex for deployment to its North Fleet operating base and was observed onF 25X1
entering the harbor at Guba Litsa Submarine Base South 25X1
12. (TSR) The expected delivery of a newly constructed C-II SSGN from Gorkiy Shipyard 112
, discussed in the previous activity report,' did not occur during this period. After 25X1
the departure of the Spoonbill YRD from Severodvinsk between the 112B 25X1
YRRN-usually associated with the fitting-out at Severodvinsk of Gorkiy-constructed subma-
rines-unexpectedly departed Severodvinsk between The Spoonbill YRD 25X1
and the 112B YRRN were observed at Gorkiy on respectively. By 25X1
the Spoonbill YRD had returned to Severodvinsk; however, no evidence of the delivery of a
newly constructed submarine was observed.

length of approximately was under the south staging shed for most of the period.
Construction of the additional launch cradle at the east end of the launch way of construction
hall 2 was continuing during the period; no indications of an impending launch from this hall
were observed.

14. (S/WN) Between the Leningrad submersible (which arrived at Naval
25X1
Base West in late August 1979) was placed on the transfer dollies on launch rail B. The transfer
dollies have been positioned on launch rail B (Figure 3) since
25X1
the Leningrad submersible was placed inside construction hall 1 for overhaul/re-
25X1
pairs/modification.
Construction Activity
15. (S/WN) During this reporting period, construction was continuing on the new quays
adjacent to the powerplant and the fitting-out quay for the Typhoon SSBN. Six additional arched
roof panels were assembled for installation on the launch dock associated with construction hall
3. Two completed panels were inside the launch dock, two were on launch rail 3, one was on the
transfer platform at the east quay, and one was on the main quay adjacent to construction hall 2.
Construction of the numerous fabrication and support buildings throughout the complex was
continuing.
16. (S/WN) Between a YFDM arrived at the shipyard. The YFDM has an
overall length of 144 meters, an outside width of 35 meters, and a well width of 24 meters. Two
wing wall cranes were in the well and have been installed. If the YFDM remains at Severodvinsk,
it will significantly increase the out-of-the-water repair capability of the shipyard complex.
Shipyard Yagry Island
17. (S/WN) Postoverhaul fitting-out of the D-I SSBN, removed from the re air hall in late
June, was continuing at RP 2 throughout the period; however, on the submarine
was not observed at the complex and was probably undergoing sea trials. On this 25X1
submarine appeared to be ready for sea and was probably transferred to its North Fleet operating
base prior to the freezing-over of the entrance to the White Sea. Between a D-I 25X1

significant topside activity was identified on the submarine after its removal from the repair hall.
The platform around the reactor compartments and removed outer-hull plate is similar to that of
Y-class SSN unit 4 prior to its return to construction hall 1 at Shipyard 402 in July 1980. During this
reporting period, no additional dismantlement was accomplished on the detached missile bay of
unit 5. The openings left by the removal of numbers 1 and 8 missile tubes have been plated over
and externally framed, indicating that some future use of this component is intended.

the bow and stern sections of the submarine had been rejoined (Figure 7). Movement of the bow
and stern sections of this submarine was accomplished on the rails which were installed on the
ledge of the basin during May and June 1981. The installation of the rails was required after the
unsatisfactory procedure used in the floating of the bow and stern sections of Y-class SSN unit 1
from the south to north ledge of the basin in June 1978. The rails are 180 meters long (further
extension is possible) and 6 meters wide; the span of the dollies used (measured after the
submarine was removed from the basin ledge) for the dismantlement of the submarine was 25X1
meters. This submarine has been redesignated Y-class SSN unit 7. By Y-class SSN 25X1
unit 7 had been removed from the basin and repositioned at the NSSSF, and no significant activity
was observed on unit 7 for the remainder of the period.

undergo a major overhaul and refuelin at Shipyard Yagry Island. Additionally, a Y-I SSBN arrived
at the facility between this Y-I could also be intended for overhaul and 25X1

this period included probably the Typhoon SSBN, a C-I SSGN, and the modified Kashin DDG
(Provornyy). On a submarine (most probably the Typhoon SSBN) was alongside the 25X1
SLBM loading facility at RP 6 and was probably engaged in the loading of the SS-NX-20 SLBM used
in the first at-sea launch of the SLBM on Checkout of the missile-handling 25X1
equipment continued throughout most of the period, with the SS-NX-20 load simulator posi-
tioned on the erector (Figure 10); however, the lifting of the load simulator by the gantry crane
was not observed. An SS-NX-20-associated, 19-meter railcar (Figure 11) was in the immediate
vicinity of the SLBM loading facility from early October through the end of December and was
probably involved in the checkout of the handling equipment as well as in the loading of the
missile on the submarine. A Ropucha LST was underneath the gantry crane on 25X1
however, loading/unloading was not observed. The erection of the extremely high lattice tower
at the SLBM loading facility (Figures 10 and 11) was complete between The 25X1
tower is approximately 130 meters high, with a base. The tower was under. 25X1
construction for approximately 9 months and will serve as a com ined light tower and lightnin
arrester. Construction of the second tower was continuing throughout the period. On 25X1
a probable SS-NX-20 missile/canister cradle was at the SLBM loading facility; on 25X1
six probable cradles were observed (Figure 11). These probable cradles are similar to 25X1
the one seen on in area A of the missile assembly/checkout areas at Nenoksa Naval 25X1
