Italian submarine Flutto

The Italian submarine Flutto was the lead vessel of the Flutto class of submarines serving in the Regia Marina during World War II.

She was built by CRDA at Monfalcone on the Adriatic coast, and was launched on 19 November 1942. The name Flutto means "billow", but can also be translated "wave", "surge" or "flood".

After commissioning and working up Flutto saw action against Allied naval forces in the Mediterranean. She had no successes, and was lost in action in July 1943 operating against Allied forces involved in Operation Husky, the invasion of Sicily.

Fate
On 11 July 1943 Flutto was on patrol in the Straits of Messina when she was detected and attacked by three British Motor Torpedo Boats (MTB’s 640, 651 and 670) operating in an anti-submarine role. Flutto was attacked and sunk.
