Shipyards at Komsomolsk-on-Amur unable to build capital ships according to a CIA report dated 1 June 1954

An item reported that in 1948 it was not possible to fit the superstructures to the hulls of the one or two battleships/cruisers partially built at Komsomolsk due to the limitations of the area. The Amur river channel was not deep enough to allow the passing of completed ships. The ships were launched without superstructures. In the winter were the ships berthed in the bay (Sakhalinksiy Zaliv] while the Amur was in that period frozen. For this reason refused the shipyards there to accept orders for other capital ships. Chosen was for the construction of smaller vessels like destroyers, frigates, minesweepers, submarines and possible motor torpedo boats. Submarines were already built even before the problems occurred with the building of capital ships.
