Italian cruiser Caio Duilio


Caio Duilio was an helicopter cruiser of the Marina Militare. Built by Navalmeccanica at Castellammare di Stabia, it was named after the Roman consul Gaius Duilius.

Design

The Andrea Doria class was intended to provide long range anti-aircraft and anti submarine protection, and as such was armed with a single Mark 10 twin rail launcher for the American Terrier surface-to-air missile forward and a large helicopter deck and hangar at the aft end of the ship. It was planned to carry three Sea King helicopters, but these proved too large for the ship, and four Agusta-Bell AB-212 helicopters were carried instead.
Close-in anti-aircraft protection was provided by eight 76mm/L62 Allargato rapid fire guns mounted on pedestals around the ship's superstructure, while two sets of triple torpedo tubes for lightweight anti-submarine torpedoes provided short range anti-submarine armament.

History

The ship was laid down on 16 May 1958, was launched on 22 December 1962, and commissioned on 30 November 1964.

The ship was assigned to the 2° Gruppo Navale d’Altura of the II Divisione Navale, based in Taranto. In the 1980s she was transferred to La Spezia, while her sister, Andrea Doria, moved from there to Taranto.
During the late 1970s, Caio Duilio was upgraded to carry the improved SM-1ER Standard missile, with improved radars and sonar also being fitted.
In 1979–1980, Caio Duilio was converted to a training cruiser to replace the old San Giorgio. The ship's original hangar was turned into classrooms and additional accommodation, with a new, smaller, hangar being built on the forward part on the helicopter deck, reducing the ship's aviation capacity to two helicopters. The aft two 76 mm guns were also removed, together with their associated fire control radars.
Caio Duilio was decommissioned on 15 December 1989, stricken on 19 July 1991 and sold for scrap on 31 December 1992.
