text: The largest Romanian warship loss of the entire war was the accidental sinking of the gunboat Lepri. The gunboat ran into a Romanian mine laid by the minelayer Aurora near Sulina in January 1941, when hostilities between the Soviet Union and the Axis had not begun. While the Royal Romanian Navy had light losses throughout the war, the state merchant navy was practically non-existent by late 1944: every ship of the SMR was sunk or damaged by the Soviet Navy and Air Force because of the light Romanian and German forces in the Black Sea that were unable to provide adequate protection.
  The following is a list of battles and operations of the World War II Black Sea Campaign involving the Romanian Navy:
  Raid on Constanța
  Operation München
  Action of 9 July 1941
  Siege of Odessa (1941)
  Crimean Campaign
  Operation Achse
  Crimean Offensive
  The Romanian Naval Forces were reorganized during the Soviet occupation of Romania as the Romanian People's Navy. Under the Romanian People's Navy, the "Nava Majestăţii Sale" (NMS) designation (or “His/Her Majesty's Ship”) that is given to each ship under Romanian Royal Navy was abolished.
  World War II Romanian Black Sea Fleet warships
  Romanian naval forces in the Black Sea consisted of four destroyers, four torpedo boats, eight submarines, three minelayers, one submarine tender, three gunboats and one training ship.
