Type CM was a miniature submarine of the Italian Navy , which was designed during the Second World War in early 1943 in collaboration with the shipyard Cantieri Riuniti dell'Adriatico ( CRDA ) in Monfalcone . The background to this was the requirement of the Italian naval command for a 100 t micro submarine that was to be manufactured in large series. The same construction contract was also awarded to Caproni-Werke Taliedo in Milan , which designed the CC type .
The prototypes developed by the Adriatico company were armed with two 45 cm standard torpedoes in the bow. Two machine guns were provided to protect the eight-man crew . By the time of the Cassibile armistice , construction of three boats had begun. These were given the designations CM 1 , CM 2 and CM 3 , CM stood for Costiero Monfalcone .
CM 1 , still in the shell, was taken over by the German Navy and was named UIT 17 there. Later the boat was returned to the Italian Navy. CM 2 also fell into German hands, was given the designation UIT 18 and was destroyed in the spring of 1944 by an Allied bombing raid on the shipyard in Monfalcone. Work on CM 3 ceased at the time of the armistice.
