Trieste-class (L9890)

The development of this landing helicopter dock began under the 2014–2015 naval program to replace the aging aircraft carrier Giuseppe Garibaldi. Construction initiated with the first steel cut in July 2017, followed by the laying of the keel in February 2018. After being launched and christened in May 2019, the vessel underwent sea trials starting in 2021. It was officially commissioned into service in December 2024, becoming the largest unit in the national fleet.

This multipurpose vessel is designed with a dual-island superstructure to separate navigation from flight operations, optimizing deck space and visual range. The flight deck incorporates a ski-jump to support short takeoff and vertical landing operations for fixed-wing aircraft, complemented by multiple landing spots and heavy-load elevators. Below the flight deck, the ship integrates a hangar and dedicated garage decks for vehicle transport. Its amphibious core features a floodable well deck capable of deploying various landing craft and hovercraft. Propulsion is managed through a combined diesel or gas scheme, supplemented by electric motors and multiple thrusters to ensure maneuverability in restricted waters. Defensive systems include multi-role guns with guided ammunition, remote weapon stations, and decoy launchers, with structural provisions for vertical launch missile systems. The sensor suite provides long-range surveillance, precision approach control, and comprehensive electronic warfare capabilities, including electronic attack and signal intelligence subsystems. Additionally, the ship maintains a NATO-standard hospital facility with surgical and diagnostic capacity.

The unit serves as a primary platform for amphibious power projection and maritime surveillance. While its main function centers on landing operations, it maintains secondary air-wing capabilities to sustain carrier-based operations when required. In operational service, the vessel has engaged in international passage exercises, including maneuvers with the Indian Navy. Its design allows for the management of complex flight operations and the transport of heavy armor and marine components for rapid landing missions. Through its integrated electronic warfare systems, the vessel is capable of situational assessment in both open sea and coastal environments.
