Construction of E-class submarines
has ended at the Severodvinsk shipyard and is tapering
off,; i -nt -in faotem-n-ate&r -at=the=-omsomotek- =--
shipyard in the Far East. Production of J-class
diesel-powered cruise-missile submarines at the
Gor'kiy shipyard may terminate in 1969 with the
completion of the 16th unit.
A major new submarine construction
program has been under way for several years. During
1967, three new classes of attack submarines were
identified; two of these, the C and V classes, are
nuclear powered. They are being. produced in the
western USSR, the C class at Gor'kiy shipyard and
the V class at Leningrad's Admiralty shipyard. C-
class production will probably reach an output of
four to six submarines a year by the early 1970's,
while V-class production at this shipyard will prob-
ably remain stable at about two units a year. Pro-
duction of the two classes almost certainly will con-
tinue through the period of the estimate and most
likely through 1975.
The third new submarine, designated
B class, is being produced at Komsomol'sk. It is
220 feet long and considerably smaller than the new
nuclear submarines of the C and V classes. We believe
that it uses .a nonnuclear propulsion system because
of its size and deployment pattern.
The main- construction facilities at
Sudomekh shipyard in Leningrad have not been used
since the cessation of the F-class program a year
or two ago. However, recent activity indicates a
new construction program may be under way. Small
submarine sections observed at Sudomekh suggest that
B-class construction may be under way there.
A reasonable.output for the two yards
would be four to five submarines per year by 1970,
with a force level by 1975 of about 25 to 35 units.
After 1970, annual production of attack submarines
could reach .a total of 10 to 15 units, about half.
of which would be nuclear powered.
