text: Two of the three planned submarines were laid down at the Galați shipyard in 1938, launched in May 1941 and commissioned in May 1943. The first one was , a 620-ton attack submarine armed with one 105 mm deck gun, one 37 mm anti-aircraft gun and six 533 mm torpedo tubes (4 bow and 2 stern). Her smaller sister ship, Rechinul, was a 585-ton minelaying submarine armed with one 20 mm anti-aircraft gun, four 533 mm torpedo tubes and 40 mines. The third planned submarine was replaced by five Italian CB midget submarines, commissioned in late 1943. The two minelayers were acquired in 1941.
  Three of the ten planned motor torpedo boats were built by Vospers in the United Kingdom and acquired in 1940. They were named Viforul,  and Vijelia. Six more MTBs, of the Power type, were built locally as the  class. They were laid down in 1939 and commissioned in 1943. The planned number of MTBs was exceeded in August 1943, when seven Italian MAS were also commissioned. These were followed by four 65-ton German S-boats in August 1944, each armed with two 500 mm torpedo tubes.
