HAPAG had ordered two combined cargo and passenger ships for their Central American coastal service of which the first was launched on 17July 1940 as the TOUMA, originally intended to be named CERIGO. Construction of the second unit, intended name initially DURAZZO, then TUROMA, was never commenced. Another order was for two small motor tugs but work never began on them either. Bremen shipowners Richard Adler & Co. intended to order two 1,600 tonne motorvessels but the contracts were never signed.
When Memelland had been re-integrated into the German Reich the German navy ordered minesweepers from Lindenau Werft. From 1942 onwards the yard constructed three units of the oil-fired M 35 type and five of the coalfired type M 40. Two further units remained uncompleted and work on three more units was never started.
Shipyard workforce rose from about 600 in 1939 to some 900 by the year 1944. A building berth gantry was erected spanning both large newbuilding berths to expedite minesweeper production.
