The Andrea Doria class were helicopter cruisers of the Italian Navy. Italy's first major new designs of the post–World War II era, these ships were primarily designed for anti-submarine warfare tasks. Initially planned for three ships, the two ships that were constructed, Andrea Doria and Caio Duilio served until 1991 in both active and training capacities. The Andrea Doria class formed the basis for the larger Vittorio Veneto that followed them.
Ordered in the 1957-58 Naval Programme, the Andrea Doria class were designed to operate the RIM-2 Terrier surface-to-air missile (SAM) system and Sikorsky SH-3 Sea King helicopters as both a platform for anti-air and anti-submarine warfare. The hull was based on the Impavido class, with a length of 149.3 metres (489 ft 10 in) and an enlarged beam to allow for the installation of a flight deck and hangar, measuring 17.3 metres (56 ft 9 in). The vessels had a draught of 5.0 m (16 ft 5 in) and displaced 5,000 tons standard and 6,500 tons loaded.
The flight deck measured 30 by 16 metres (98 by 52 ft) and was placed aft of the superstructure. It was cantilevered out at the stern to provide extra operational space.
The class was powered by four Foster Wheeler boilers. These provided the power to two double reduction geared steam-powered turbines creating 60,000 horsepower (45,000 kW) which drove two shafts. This gave the cruisers a maximum speed of 31 knots (57 km/h; 36 mph) and an operating range of 6,000 nautical miles (11,000 km; 6,900 mi) at 20 knots (37 km/h; 23 mph).
