Marcello-class submarine

(Redirected from Italian submarine Morosini)

The Marcello class was a class of nine submarines built in 1937 and 1938 by CRDA in Trieste for the Royal Italian Navy (Italian: Regia Marina). Two similar submarines built in 1939 at La Spezia by Oto Melara are sometimes considered part of the class. All eleven served in the Mediterranean Sea at the start of the Second World War. After Provana's 1940 sinking, the remaining boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in August 1940. After four boats had been sunk in the Atlantic, Barbarigo and Comandante Cappellini were then selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns.[1] Only Dandolo was in operational condition at the end of the war.

German submarine UIT24 in the Inland Sea, Japan, August, 1944. UIT-24 was the ex-Italian submarine Comandante Cappelini and was later the IJN I-503.

Lorenzo Marcello

edit

Lorenzo Marcello (pennant number ML) was launched on 20 November 1937[2] and completed on 5 March 1938. When Italy declared war, Marcello was temporarily disabled by air conditioning system leaks. Leakage of chloromethane refrigerants during submerged operations had caused central nervous system poisoning of the crew. After unsuccessful patrols in the Mediterranean, Marcello sailed on 31 October 1940 and passed the Strait of Gibraltar on 5 November for an Atlantic patrol to Bordeaux on 2 December. Marcello sank one ship on its first BETASOM patrol and was lost to unknown causes on its next patrol in late February 1941.[3]

Enrico Dandolo

edit

Enrico Dandolo (pennant number DO) was launched 20 November 1937[2] and completed on 25 March 1938. After unsuccessful patrols in the Mediterranean, Dandolo sailed on 13 August 1940 and passed the Strait of Gibraltar on 16 August for an Atlantic patrol to Bordeaux on 10 September. Dandolo sank one ship and damaged another en route to Bordeaux. After an unsuccessful patrol, Dandolo sank one ship on its second BETASOM patrol. After another unsuccessful patrol, Dandolo sailed from Bordeaux on 26 June, passed the Strait of Gibraltar on 2 July, and returned to Naples on 7 July. Dandolo spent the remainder of the war in the Mediterranean damaging a neutral French tanker on 4 November 1941, sinking the neutral Spanish freighter Castillo Oropesa on 8 November 1941, and damaging the cruiser HMS Cleopatra on 16 July 1943. Dandolo sailed to the United States after the Italian armistice, and was scrapped in 1948.[4]

Sebastiano Veniero

edit

Sebastiano Veniero (pennant number VN) was launched 14 February 1938[2] and completed on 6 June. After an unsuccessful Mediterranean patrol, Veniero passed the Strait of Gibraltar on 7 July 1940 for an Atlantic patrol near the Canary Islands and returned past Gibraltar on 27 July. This was the first Axis submarine to pass Gibraltar during World War II, and the report of conditions delivered upon return to Naples on 1 August assisted future attempts to pass the strait. Veniero sailed on 28 September 1940 and passed the Strait of Gibraltar for an Atlantic patrol to Bordeaux on 2 November. After sinking two ships in six BETASOM patrols, Veniero sailed from Bordeaux on 8 August 1941 and returned through the Strait of Gibraltar to La Spezia on 2 September. On its seventh patrol after return to the Mediterranean, Veniero was assumed sunk (identification not confirmed) by a Consolidated PBY Catalina on 7 June 1942.[7]

edit
Main article: Italian submarine Barbarigo

Agostino Barbarigo (pennant number BO) was launched 12 June 1938.[2] After unsuccessful patrols in the Mediterranean, Barbarigo sailed on 13 August 1940 and passed the Strait of Gibraltar for an Atlantic patrol to Bordeaux on 8 September. After unsuccessful BETASOM patrols from 14 October to 13 November 1940 and from 10 February to 8 March 1941, Barbarigo damaged the British freighter Manchester Port on 15 May 1941. Barbarigo sank two ships on its fourth BETASOM patrol. After an unsuccessful patrol from 22 October to 12 November 1941, Barbarigo sank the neutral Spanish freighter Navemar on 23 January 1942. Barbarigo sank one ship and damaged another during its seventh BETASOM patrol. Following an encounter with cruisers USS Omaha and USS Milwaukee coming to assist the damaged ship, Captain Grossi notoriously asserted he had sunk a battleship of the United States Navy. On the following patrol, a similarly unsuccessful launch of torpedoes at the Flower-class corvette HMS Petunia was reported as the sinking of another battleship. Barbarigo sank two Allied ships and another neutral Spanish freighter Monte Igueldo on its ninth BETASOM patrol.[9] After conversion to a transport submarine, Barbarigo sailed from Bordeaux on 17 June 1943 and was sunk by aircraft in the Bay of Biscay.[10]

During the following patrol, Cappellini participated in rescue operations of the Laconia incident. After another unsuccessful patrol, Cappelini was converted to a transport submarine.[13] Cappellini sailed on 11 May and reached Singapore on 13 July 1943 with 160 tons of mercury, aluminum, welding steel, 20mm guns, ammunition, bomb prototypes, bombsights and tank blueprints.[10] Cappellini was seized by Germany following the Italian armistice of September 1943 and commissioned into the Kriegsmarine as UIT-24. UIT-24 was then seized by the Imperial Japanese Navy following German surrender in May 1945 and renamed I-503. I-503 was found at Kobe when Japan surrendered and scuttled in Kii Suido by the United States Navy.[14]
