The CB class was a group of midget submarines built for the Italian Navy during World War II. However, they were also used by several other navies, seeing action in the Mediterranean and in the Black Sea.

The submarines were designed and built by Caproni. They were used as coastal defence units, being a significant improvement of the previous CA class. Each unit had a standard (surfaced) displacement of 35.4 tons and a submerged displacement of 44.3 tons. They measured 15 metres (49 ft 3 in) in length, had a beam of 3 metres (9 ft 10 in) and a draught of 2.05 metres (6 ft 9 in). Power plant consisted of one Isotta Fraschini diesel engine and one Brown Boveri electric motor, both generating a total of 97 kilowatts (130 hp) powering a single shaft, resulting in a surfaced top speed of 7.5 knots (13.9 km/h; 8.6 mph) and a submerged top speed of 7 knots (13 km/h; 8.1 mph). Each boat was armed with two externally-mounted 450-millimetre (18 in) torpedoes, each tube could be reloaded without removing the vessel from water. The two torpedoes could also be replaced by two mines. Each boat had a crew of four, aided in navigation by a small conning tower.
