I. BACKGROUND
This study is in partial response to a continuing project requiring
the identification of ships at selected Sino Soviet Bloc shipyards from
overhead photography.
Severodvinsk Shipyard 402 is of the highest intelligence priority
since it is the lead yard engaged in the production of Soviet nuclear
attack and missile submarines.
has provided by far the best quality large
scale photography of this yard - permitting the first
detailed photo interpretation of this installation since World War II.
II. SCOPE OF THIS REPORT
Because of the importance of this installation and the excellent
quality of the photography obtained of it the following additions have
been made to the standard project reporting format:
a. The text has been greatly expanded to encompass a more detailed
description of specific items of interest.
b. Line drawings have been utilized to illustrate in greater
detail those items of greatest significance.
c. The most significant information has been summarized in
highlight form - extracts from which have been pre-released via cable.
III. MENSURAL AND GRAPHIC INFORMATION
All measurements, either specifically stated in the text of this
report or used to annotate the line drawings, were derived by the Technical
Intelligence Division, NPIC; they are considered accurate within plus or
minus five. feet or five percent, whichever is greater.

All line drawings, with the exception of Figures 1+e and 5b, have
been drawn to a rough scale of approximately one inch to fifty feet.
Figures 1+e and 5b have been drawn to a rough scale of approximately one
inch to twenty-five feet.
Whenever the location of end points could not be determined with
full confidence the imagery in question has been depicted in the line
drawings by means of a dashed line.
Obliquity or lack of sharp waterline contrast precluded observation
of the actual waterline beam of nearly all the submarines.
The actual maximum beam on each of the two submarines in the
floating docks could not be determined due to probable scaffolding.
Questionable end points also precluded an accurate determination of certain
imagery observed on the visible deck of these two ships.

1. Extensive modification of the ballistic missile system is
apparently in progress aboard the "G" Class SSB berthed along the fitting-
out quay of the north (Yagry Island) repair facility. This evaluation is
based upon the height, from the deck, of each of the three exposed missile
tubes - a vertical distance of approximately or at least some
feet lower than the tubes aboard the standard lass. The he' of the
partially dismantled sail area forward of the tubes is roughly
Lack of outer side panels on either side or aft of the missile tubes also
suggests that extensive modification work has yet to be performed on this
submarine. (See annotation 5, Figure 6.)
2. Six cylindrical sections, having maximum outside c.iameters ranging
from (approximate) are placed adjacent to a cuay on the south
side o to s oye Estuary east of the main launch basin. Based on size,
shape and location (at a shipyard constructing' submarines) the most
reasonable identification of these objects is that the are submarine hull
sections. Lengths of each of these sections vary from Five
of the sections are placed on their transverse (upright) axes; several small
holes can be seen within the rim of one of these sections. The'sixth
section is lying along its longitudinal axis and is slightly tapered at one
end. A very large floating crane is observed alongside the quay within
working radius of the six sections. (See annotation 5, Figure 5.)
3. Nuclear submarine refueling (recoring) can be established as a
major function of the Nuclear Submarine Special Support Facility, Yagry
Island. Evaluation is based, in part, on the presence at this facility of
a specialized naval auxiliary ("PM-124") - a ship most likely having a
nuclear support mission - and the observation of a structure on the quay
similar to the spent fuel handling structures ("M-130" houses) seen at
U.S. naval nuclear refueling facilities. (See annotations 7 and 9.
Figure 8.)

these submarines and the main quay. A probable decontamination (DECON)
radio-active control (RADCON) function can be ascribed to each of the two
barges servicing the submarines at the Nuclear Submarine Special Support
Facility, Yagry Island. No barges of this type are located alongside any
of the four conventionally powered submarines observed at this shipyard.
(See annotations 1, 3, 6, 10 and 14, Figure 4; annotation 12, Figure 6;
and annotations 3 and 5, Figure 8.)
5. Additional photo/mensural analysis has led to a more conclusive
identification of each of the submarines observed in the two large floating
docks at Severodvinsk.
a. A scaffolded "N" Class SSN (with an approximate visible length
over-all of at least 1 11 occupies the floating dock placed per-
pendicularly to the 1.LUU_L1jV'-UUU quay of the Main Yard. (See annotation
9, Figure 4.)
b. The floating dock alongside the fitting-out quay, North Yard
(Yagry Island), contains an "H" Class SSBN; the approximate length
over-all of this submarine from the after edge of the vertical stern
fin to the leading edge of theforwardmost shed over the bow is no
greater than (See annotation 15, Figure 6.)
6. Floating vertical security screens, each roughly 50 feet in length,
are positioned along the outboard sides of most of the elevated missile
launchers aboard the "E-II" Class SSGN's berthed alongside the fitting-out
quay of the main yard. (See letter symbols to annotations 2, 4 and 7,
Figure 4.)

1. Rectangular service barge
Barge has an irregularly s ape superstructure or approximately three-
fourths of its length. The leading edge of the barge is in line with
the leading edge of the sail of the E-II SSGN berthed alongside it.
2. E-II Class SSGN (waterline length approx
All but the aftermost set of missile launchers are elevated. Three
vertical screens (symbols A, B, and C. annotation 2), each approximately
50 feet in length, are placed along the outboard side of the submarine
directly in line with three of the launchers. All four sets of exhaust
deflectors are uncovered. The submarine is secured to quay by means of
bow and stern lines. A probable mooring buoy is positioned on the port
quarter of the submarine just abaft the #4 exhaust port. A water dis-
turbance is located along the port quarter and along the port side of
the submarine by the #1 launcher. A white line, possibly a cable or
piping, leads from the edge of the quay, up and over the barge inboard
of the sub, and down the outboard side of the barge where it is lost in
the shadows at a point in line with the second set of exhaust ports on
the submarine. A goosenecked portal crane is working on the quay along-
side the E-II Class SSGN. (For a detailed line drawing of items 1 and
2 above refer to Figure 4a.)
3. Rectangular service barge
Superstructure configuration differs from that observed on barge along-
side first E-II (annotation #1 above). Main superstructure is approx-
imately D in length; a possible stick mast and a small possible
crane are located at opposite ends of this superstructure. The possible
crane is located in line with the spacing between the number two and
three launchers on the submarine. A small structure is located near
each end of the barge. The leading edge of the barge is in line with
the leading edge of the sail of the E-II SSGN berthed alongside.
4. E-II Class SSGN (waterline length approx 365').
All four sets of missile launchers are elevated. Covers are not present
on the last three sets of missile tube exhaust ports; the status of the
forward ports cannot be determined. Two vertical floating screens (sym-
bols A and B. annotation 4) shield the forward two-thirds of the first

edge of the number two port exhaust deflector. From the submarine this
line is hung along the outboard side of the barge superstructure - then
snakes across the top of the barge and apparently drops down the inboard
side of the barge to the quay below. (For a detailed line drawing of
items 3 and 4 above refer to Figure 4b.)

6. Rectangular service barge (LOA approx 190').
Topside configuration differs from that seen on items 1 or 3 above.
Barge is moored inboard of an E-II SSGN in nearly the same position
and stern lines lead to the quay. A white line is faintly visible in
approximately the same position on this submarine as the possible power
cable observed leading from the deck of the E-II SSGN (item 4) discussed
above. Shadow from a crane obscures the line on top of the barge. An
unidentified crane is located on the quay in line with the after edge

 Extreme forward end of bow may be partially covered by scaffolding. The
hull outline toward the stern is indistinct due to clutter caused by
scaffolding. No vertical stern fin is visible, although it should be
noted that the submarine is oriented along a line parallel to the sun
angle - thereby precluding the observation of any significant shadow
factor. Criteria utilized to establish this identification include:
(1) a short sail which slopes aft to meet the deckline; (2) a visible
LOA which approximates the LOA for the longer variant of the N Class;
(3) the observation of a bulbous bow - similar to the other "N" Class
SSN's seen at this yard on the same photography - although minus a
"staybrite" belt; and (4) the absence of any missile launchers or ex-
haust deflectors. The sail is scaffolded along either side. A very
small vertical protrusion is located just forward of an unidentified
rectangular object on the after deck of the submarine. A line extends
from this protrusion across to the drydock wall from which it may lead
to a barge alongside the dock. (For a line drawing of items 8 and 9
above refer to Figure 4c.)
Barge contains a long rectangular superstructure at one end. Topside
configuration is unlike that observed on items 1, 3, and 6.
11. "N" Class SSN (waterline length
An unidentified white object approximately in length is located
on the deck of the submarine approximately abaft the sail. Two
possible pipes or ducts extend from this object to the side of a rec-
tangular service barge inboard of the submarine. A large duct leads

the submarine to the top of a rectangular service barge berthed inboard
of the "N" Class. A small white shack (approximately uin length)
is located on the deck of the SSN approximately aft of the sail.
A portal crane is working on the quay by the "N" Class SSN.
12. Unidentified small yard craft with rounded hull

The topside features of this barge again differ from the detail visible
on the other nuclear submarine service barges seen along this quay.
Two large possible ducts appear to connect the inboard edge of the barge
to an elevated narrow rectangular structure situated on the edge of the
quay. These connections are just forward (along a fore-and-aft axis)
of the position where two possible pipes or ducts join this barge from
the submarine. (For a detailed line drawing of items 11-14 above refer

circular "frames", having maximum diameters from 211
placed on the quay just east of construction hall. Two of ese objects
(items "A"; and "B" have the same angular configuration as the two arch-
shaped structures observed on the corner of the quay by the side launch-
ing way (see annotation 1, Figure 3). The maximum inner distance between
the angular extensions (or "legs") along the baselines of both items "A"
and "B" is approximately 40 feet. Each of these two objects tapers from
its baseline to a distance of approximately l across its narrowest 2 1
point. The perpendicular distance from this narrowest point to the
baseline is approximately for each object ("A" and "B"). (For
a detailed line drawing of . items A", "B", and "C" above see Figure 4e.)

Outer housing has been removed from the after two-thirds of the sail
exposing the three missile tubes. The uppermost section of the forward
part of the sail may also be removed. Height of forward part of sail
is approximately I I above the deck although shadow factor from which
this dimension is derived is less than optimum. Height of each of the
three missile tubes (based on good shadow factor) is approximately
is the distance measured from the top of each of the
Tubes to the topside deck level of the submarine. The extremities of
each of these tube shadows terminate on what appears to be the nearly
flat deck surface upon which the outer sail housing to the missile com-
partment would normally be positioned.) From a U.S. Navy PIC scale draw-
ing of the "standard "G" Class SSB it would appear that the height of
the tubes above deck level is no less than - or approximately=
feet higher than the height of the tubes observed on this "G" Class.
Additional photographic evidence of probable modification to the missile
system aboard a "G" Class SSB has been sighted at Shipyard 202, Vladi-

Approximate dimensions for this dock are as follows: LOA of walls -
maximum (outer) width - II inner dock width A small
crane is visible on top of each wall of the dock.
15. "H" Class SSBN in floating dock.
The vertical stern fin and three ballistic missile tubes/caps on top
of the after part of the sail are plainly visible. The distance between
the aftermost edge of the stern fin and the leading edge of the shed
extension over the bow of the submarine is approximately 0 The
submarine LOA is probabl slightly less than since the bow shed
extension (of some does not appear to be placed directly in line
with the centerline axis o the submarine. The slant range distance be-
tween the after edge of the stern fin to the after edge of the aftermost
missile tubes is approximately 0 The after sail housing abaft
the missile tubes has been removed as have the uppermost side panels on
either side of the missile tube compartment. Temporary structures or
sheds cover the forward section of the submarine from just forward of
the sail to the bow - and a large area of the ship between the stern fin
and a point approximately from the stern. The minimum width
amidships is approximate) - although this includes an undeter-
mined width of probable scaffolding along each side of the submarine.
The height (determined from shadow visible on the dock floor) from the
top of the vertical stern fin to the dock floor is roughly (For

identified rectangular structure, approximately in length, is
visible between the positions of the second and third sets of missile

from the bow of the submarine. An unidentified linear "duct-

5. Probable DECON/RADCON barge
Three probable vents are visible atop the amidships barge superstructure
(dimensions of barge superstructure - approximately 135' x 15). This
barge is virtually identical to the probable DECON/RADCON barge servicing
the E-II SSGN at this facility (see annotation 3, Figure 8). At least
three possible pipes are angled from the barge to an area on the N Class
SSN just abaft the white shack aft of the sail. Three additional faint
lines, possibly pipes, are visible through the shadows between the barge
and the white shack on the "N" Class.

at United States Navy Yards to load spent nuclear fuel elements into con-

It is quite likely in view of the simi-
larities o position and topside detail that these are, in
fact, the same two submarines, thereby indicating a probable
maintenance evolution of some magnitude.
b. Extensive possible piping or ductwork leads from the two nearly
identical service barges to the probable location of the reactor
area aboard each of these two submarines. Possible vents atop
each of the barges provide further evidence to support their
identification as probable DECON/RADCON barges.
d. The possible "M-130" type structure is located in the most
suitable position for the quayside portal crane to work be-
tween it and the probable location of the reactor area aboard
the "N" Class SSN.
e. The unique cranes aboard the "PM'124" are identical to those
aboard the LEPSE AG - a nuclear waste disposal ship.
f. Inner security fencing is visible along the quay by both
submarines. This is in addition to the security fencing
surrounding the entire facility.

States nuclear submarines.

objects. There is as yet no rail line along this quay, but a spur line
is observed under construction from the repair facility, Yagry Island
(Figure 6), toward the southwestern end of Yagry Island (Figures 7 and
8).
NOTE: The, establishment of nuclear submarine refueling (recoring) asa maj-
or function of this facility is based upon the following evidence.
a. An "E" and an "N" Class nuclear submarine - one with a frame-
work along the outer hull, the other with a white shed abaft
the sail - have both been sighted at, this facility over a
