Service
In 1942, after the United States entered the war, Junio Valerio Borghese, commander of the Decima MAS, devised a plan to attack New York Harbor using a CA type midget submarine and commando frogmen. The midget submarine would be transported across the Atlantic by being carried on the deck of a larger submarine. The Italian submarine was chosen for the task and modified at the Italian base in Bordeaux. CA 2 was transported by rail from Italy and trials, which were conducted near La Pallice, were supervised by Borghese himself during late 1942. Leonardo Da Vinci was sunk in May 1943 before the operation could be carried out. No new boat was available and the Italian Armistice stopped further planning.
