The Trieste-class landing helicopter dock will be equipped with heavy and medium helicopters (EH101 and NH90 respectively) and Lockheed Martin F-35B Lightning II aircraft. It will have a floodable well deck below the hangar level able to accommodate amphibious landing vessels such as LCM (new Cantieri Navali Vittoria LCM23 type), LCAC, and newer L-CAT (Landing Catamaran) vessels. It also can carry Ariete MBT, B1 Centauro tank destroyers, and up to 600 soldiers. Its base will be in Taranto.
The unit is being built at Fincantieri's Castellamare di Stabia facility near Naples. The first cut was 12 January 2017 and completed construction of the hull on 25 May 2019, while the official delivery to the Italian Navy will be around the first half of 2022. It is the largest Italian military ship built after the Second World War.
