Project history
Coastal boats for protection of harbours. On three prototypes were ordered in 1943 to Caproni (CC) and CRDA (CM). Till September, 1943 the order (besides prototypes) on 16 CM and 8 CCs was given out.
After comparative trials of prototypes it was supposed to adjust a mass building of better sample under index CU (unified).
Before armistice signing only one submarine of CC class and two of CM class were laid down, one of which, CM1, was launched. For CC2, CC3 and CM3 there has been begun preparing of materials, but really they were not laid down. Incomplete boats in September, 1943 were captured by Germans. It has been decided to complete CM1 and CM2, renamed UIT17 and UIT18 respectively. CM1 (UIT17) was commissioned in January, 1945 and CM2 (UIT18) was damaged on a slipway by Allied aircraft in May, 1944.
Modernizations
None.
Naval service
CM1 was captured by Germans, commissioned by them as UIT17 and transferred to RSI. Italian crew led the boat to join Royal Italian navy shortly after.
