The three San Giorgio class amphibious transport dock ships in service with the Italian Navy were built by Fincantieri at their Riva Trigoso shipyard. The three ships are: MM San Giorgio (L9892) commissioned in 1987, MM San Marco (L9893), commissioned in 1988, and MM San Giusto (L9894), commissioned in 1994. The ships are based at the Brindisi naval base on the Adriatic coast.
The ships provide roll-on/roll-off landing capability for land embarkation; air lift through the use of high capacity aircraft such as Chinook-type helicopters; and transportation by sea to shore, using the ship's own systems and landing ships for landing on unprepared shores.
Design
The San Giorgio class ships can lift a battalion of troops, with up to 30 medium tanks, or 36 tracked armoured vehicles. The stern floodable dock can accommodate three LCM (or MTM) landing craft, each capable of transporting 30t of material. Three davits on the main deck are provided for the deployment of three LCVP (or MTP) landing craft and a patrol boat.
San Giusto has a full load displacement 300t higher than her sister ships. The ship has no bow doors for beach landings. The three davits for the deployment of landing craft and the patrol boat are relocated to a sponson installed on the port side of the ship instead of on the flight deck.
San Giorgio and San Marco are to be modified to increase the flight deck for helicopter operations. The 76mm gun mount and two port side davits for LCVP's will be removed, giving space for a new central flight deck. This will allow two EH 101 helicopters and two medium helicopters (NH 90 or AB 212) to be launched at the same time. The LCVP's are to be moved to below the sponson and the bow doors will also be removed.
A 30t lift and a two-hook travelling crane, each hook rated to carry 40t, are installed on the ship providing the capability of autonomous loading and unloading operations completely independent of harbour facilities.
Aircraft
The main flight deck which runs almost the length of the ship, has three helicopter landing spots. The ship can accommodate three Sea King SH-3D helicopters or five Agusta Bell AB-212 helicopters.
Combat system
The ship has the IPN 20 combat data system and the NA 10 fire control system, both from Selex Sistemi Integrati (formerly Alenia Marconi Systems). It is also equipped with a telecommunications system from Elmer MAC.
Weapon systems
An Oto Melara 76/62 gun is installed on the gun deck at the bow of the ship. The gun fires 6kg rounds at a firing rate of over 80 rounds/min to a target range of 8.5 nautical miles.
The ship is also armed with two Oerlikon 20mm machine guns for close defence.
The ship's electronic warfare system comprises an electronic countermeasures and electronic support measures (ECM/ESM) suite supplied by Elettronica of Rome.
Sensors
The ship's radar suite includes the Selex Sensors & Airborne Systems (formerly Galileo Avionica) MM/SPQ 702 search radar and SPN-748 navigation radar, both operating at I band, and the Selex RTN-10X fire control radar, operating at I and J bands.
Propulsion
The ship is powered by two GMT A 420.12 diesel engines supplied by the Diesel Engine Division of Fincantieri. The engines provide 16,800hp, delivered to two shafts with constant pitch propellers. The ship is equipped with four Fincantieri GMTB 230.6 diesel generators supplying 3,080kW. The propulsion system provides a maximum continuous speed of 21 knots. At the economical speed of 16 knots the maximum range of the ship is 7,500 nautical miles.
