former Polish-built B 31 class, and is probably one of the
following vessels: PERVOURALSK, PROKOP

none or the vessels nave saiied
in free waters, but have gone from Polish shipyards in Gdansk
(Danzig-) to Leningrad. Pavlograd and Perm, however,-called-
at Tallin'en route. Class B 31 was inaugurated in 1952 and
has since undergone alterations to satisfy requirements for a
modern cargo vessel, Even so, the latest version of this type,
to which the four above-mentioned vessels belong, is still out

turbine. It has bunkerage for 460 tons and a daily consump-
tion of 23 tons.
Of the five groups of antennas seen on the photograph, the
one farthest abaft, which is also the largest, is probably
identical with the radar type (BIGNET?) which h been observed
on the reconstructed T-43-class mines wee ers 50X11-HUM

The vessel may be assumed to be used for early air warning.
