Development
The San Giorgio class, also known as the "Saints class" of Landing Platform Dock (LPD) for amphibious warships warfare were designed to replace much older vessels. They were to succeed to the Grado class, decommissioned at the end of the 1980s. They were to constitute the bulk of the modernized "Sea Projection Force", the amphibious component of the Italian Armed Forces. To make a rapid brush-like portait of Amphibious assets of the Marina Militare during the cold war, the early 1950 to 1981 counted on 14 MFP-D built in Germany and Italy, a WW2 design, added to ten LCT(3) ex-RN, 20 LCMs, 30 LCVPs and 6 LSSL under MDAP. They were kept until the 1980s, waiting for a new generation, the 1967 Quarto class Landing Ships (three built). But the latter were seen largely as a failure, and were axed in the 1968 budget cuts. Instead, were purchased ex-US De Soto Country LSTs, very capable and large vessels, purchased in 1981 as Grado and Caorle. The De Soto class however were 1950s tech vessels, and lacked a flight deck or dock, they were glorified, large (7,823 long tons full load) WW2 LSTs essentially, carrying 28 medium tanks or vehicles and up to 580 troops.
Launch of San Giorgio in 1987
The US showed the new amphibious trend clearly was around LHDs for rapid operations, both projecting smaller landing crafts and landing troops by air assets simultaneously, offering far greater tactical possibilities. The main carrier would stay out of harm inside a fleet protection bubble. Thus in the early 1980s was planned a replacement. The initial specs targets was not for massive US analogue ships of 50,000 tonnes with both an helicopter/VTOL hangar and vehicle hangar plus dock, but a more reasonable 5,000 tonnes vessel keeping its helicopters on flight deck, but without hangar.
The Grado class were indeed pure landing units, and the new vessels because of their deck received a side island and looked like in the first draft as a reduced Garibaldi or Tarawa. Crucially they were called as LPDs, combining the advantages of an AKA (Attack Cargo Ship) and a LSD (Landing Ship Dock), floodable for indirect landing on the beach by intermediary transports, the mothership staying afar from the shore, defending by its escort. These "transport and disembarkation ships" could bot bring assets from port to port if needed, but was mostly tailored for port to shore operations. Specifications also included natural disasters reflief, rescue and assistance operations at home and abroad. It was to intervene to the benefit of a population after a major disaster or intervene in a major pollution episode, and to act as training ship, embarking Naval Academy Officer Cadets for summer educational cruises, which needed a reconfiguration of the main hangar, which needed to stay modular.
The yard's R&D officers in charge did not started on a blank page and could take advantage in their experience building large commercial ferries. To the base design was added self-defensive light armament, and overall good operational flexibility. The small size and stability constraints meant it could not have an helicopter hangar. Those had to be parked on deck only, and so exposed to the eklements. This was judged acceptable in regard to the intended primary operational theater, the Mediterranean. Thus, the "saints" are not LHDs despite their flight deck.
The design was ready in 1984 and the first ships, immatriculated L 9892, San Giorgio (Patron saint of Milan, Northwest Italy) was ordered to Riva Trigoso Yard (Fincantieri), Sestri Levante, Genoa. She was laid down on May, 27 1985 and her sister San Marco (the patron saint of Venice and Venetia) even earlier on March, 28. San Giusto (Justus of Trieste) was ordered six years later on August, 19, 1991 of a modified design (see later).

Hull and general design
The San Giorgio class as rated at 5000 tonnes standard, and 7,960 t (7,830 long tons) fully loaded, but 8,000 t (7,900 long tons) for San Giusto. They all however have the same size, with a length of 133 m (436 ft) and Beam of 20.5 m (67 ft) and a draught of 5.3 m (17 ft). Transom stern is necessary for the main dock entry. The middle aft section at waterline level is this tailored as a catamaran, to house landing craft. This is however a small and narrow docj at just 20.5 x 7 m, in which three LCM landing crafts could be stored, three other smaller craft on the main deck. Loading capacity is 1,000 tonnes. Accomodations includes a 99 m³ refrigerated store, 300 m³ dry cargo storage, 60 tonnes of aviation fuel. Normal capacity is 350 equipped infantry, 30 AFVs and softskin vehicles? The ships were tested with the whole range of Italian vehicles in ioperations a the time, such as the VCC-1 IFV and Arisgator or AAV7 amphibious APC (an Italian LVTP-7). The units also have an operating room, medical clinic, dental office, x-ray room, gynecological room and delivery room. The hull's continuous deck did not extended to the bow, so to leave space for a bow cannon having sufficient firing arc. The slender bow stem comprises a waterline hydrodynamic bulb while superstructures are a single block integrated the hangar. On the starboard side is located the relatively large, blocky control bridge, with single smokestack and short mast to support the main radar and telecommunications antennae. The internal hull is divided in to four levels:- Flight deck and superstructure, which includes the bridge, operations rooms, the flight operations assistance center and official accommodation;
- Corridor deck, main accommodation and living quarters, messes and cabins.
- Main hangar/Garage, modular with a continuous deck from stern to bow and ramps to access the dock aft.
- Lower area, with storages rooms, engine rooms and generators, main galley and refrigeration rooms, air conditioning unit, troop accomodations, and thruster bow room, dock aft.

Divers from various nations will work together to rescue submariners during the exercise in the Mediterranean. Twenty-seven participating nations, including 14 NATO nations will test their capabilities and interoperability. Four submarines with up to 52 crewmembers aboard will be placed on the bottom of the ocean, while rescue forces with rescue vehicles and systems work together to solve complex disaster rescue problems. U.S. Navy photo by Chief Journalist Dave Fliesen (RELEASED)[/caption] The beating hart of "Saints" rests on two, massive 12-Cylinder Grandi Motori Trieste A-420.12 diesels, producing together a total of 16,800 hp (12,353 kW). Each is capable of operating two axles, each coupled to a reduction unit drive. The end shaft then turns a five-bladed variable pitch propeller to provide enough flexibility for port maneuverability and this is compounded by an auxiliary electric thruster with bow propeller, both solutions inspired by civilian ferries. Top speed is 20 and range approximately 4,500 miles at this top speed, 21 knots (39 km/h; 24 mph) on trials, max, light. The overall range of 7,500 nautical miles (13,900 km; 8,600 mi) is obtained as cruise speed of 16 knots (30 km/h; 18 mph). This is the main advantage of an all-diesel solution combining two diesel engines Grandi Motori Trieste GMT A 420.12, 6,264 kW (8,400 hp) each and four diesel engine generators Grandi Motori Trieste GMT B230.6, 770 kW (1,030 hp) each, the latter are however involved in electric supply, not propulsion: Electricity is provided by the four GMT B 230.6 groups 770 kW each (450 V, 60 Hz) when the main diesels are cold. The ship comes indeed with a Platform Operations Center, including remote control of the machinery with full automation for the power plant, with screens, gauges and alarms display.
Armament
The armament consisted of a 76/62 mm OTO-Melara anti-aircraft gun, two 20 mm Oerlikon machine guns, two rocket launchers and a Simmel very large smoke projector.Main: 1985 Oto-breda Super Rapido 76 mm gun
The "super rapido" os a well known, well exported light AA gun also usable against ships and missiles to some extent. It fires a 6×636mm 6.3 kilograms (14 lb) round with 12.5 kilograms (28 lb) cartridge, 2.35 kilograms (5.2 lb) charge. The mount can elevate −15°/+85° at 35°/s for 360° at 60°/s, at MV 915 m/s (3,000 ft/s), 120 rpm, 16,000 m. Normal cap. is 80 ready rounds. It was removed from San Giorgio and San Marco to increase flight deck space.Secondary: OTO 20mm
Two OTO Melara Oerlikon KBA 25/80 mm guns were installed on the deck. The Oerlikon KBA 25 mm was developed as a succesor to the legendary 20 mm in 1973. They could be instaled on integrated mounts with fast moves, assisted, and far better integrated targeting system. Specs: 112 kg (247 lb), 2,806 mm (110.5 in), firing the NATO 25×137mm at 100-200 rpm with Dual Feed at MV 1,100 m/s (3,600 ft/s), RA 3,020 m (9,910 ft) to 5,850 m (19,190 ft)Sensors
Sensors and processing systems comprised the following: -SMA MM/SPQ 702 search radar -GEM Elettronica navigation radar: MM/SPN-748 then MM/SPN-753(V)9 and now dual band radar (X/Ka) MM/SPN-760(V) -Selex ES RTN-10X fire control radar with the Argo NA-10 firing direction system -Elettronica SpA INS-3 ECM/ESM suite for electronic warfare -GPS/NAVSTAR navigation system -NIXIE noise generation systemCarrying capacity
The garage is used for loading and unloading vehicles on both ends through the use of ramps, with a folding stern door, side sliding door starboard, and bow door lifting up. It was eliniminated during modernization.
At the extreme stern, below the waterline is located the flooded dock, to house a single 18.50 m long landing crafts with two other MTMs harnessed on special saddles on the flight deck. The dock threshold is below the waterline so it is flooded by just opening its stern door, and dried up door closed, of flooded door close using seacocks. The connection between the dock and comprises a large ramp area called the "beach", for direct loading of a vehicle on board the LCT, stern turn to the dock door. The dock could also be used as extra vehicle loading area. Via the side doors and loaded generally the palettized storage and ammunition. This level also hosts the hydraulic power units, service rooms, laundry, boatswain's room and secretariats.
A fast motorboat for VIP transport operated by crane is located forward of the island.
Air Group
AW-212 of the Army
NH-90A of the Marina
EW-101 of the Marina
Her flight deck is limited due to the large island and lacement of the two landing crafts on deck edges, and it is divided into two areas: The bow area, approximately 800 m², for parking and another aft area of approximately 900 m² for take-off and landing, with four spots, landing lights, and a luminous path for night operations.
Aircraft carried were usually either three AW-101 and five Agusta Bell AB-212 helicopters or SH90A. The ship could resupply and refill them in operations, including avgas and supplies, armament, that can be mounted via the lift on the port side of the island on deck, narrow, but still ling and large enough to carry down the hangar any helicopter on deck if needed.

San Giorgio in Brindisi
First built at Fincantieri, Riva Trigoso shipyard and officially launched on 21 February 1987, she had to wait until the 25th to sail to her outfitting site due to bad weather, and was commissioned on 13 February 1988.
Previous San Giorgio ships were the

In December 2014, she took part search and rescue operations for the Norman Atlantic, which was successful. On 3 August 2016, she patrolled against smugglers and human traffickers and was tasked to train the Libyan Coast Guard, Navy and enforce the arms embargo according to UN resolutions during the civil war. Libyan cadets and officers were trained onboard San Giorgio from September.
Rear Admiral Frumento replaced his Greek counterpart Theodoros Mikropoulos at the head of this operation by October 19, 2020, still aboard San Giorgio as flagship.
Delivered on 14 May 1988 and unlike her sister ship, San Marco main tasks were humanitarian rescue operations as well as home Civil Protection, for which she was outfitted with a larger, more complete hospital, greater capacity to produce drinking water and sets of equipments for anti-pollution operations, notably with tanks filled with biodegradable solvents and rubber barriers.
From December 1992 San Giorgio, San Marco carried San Marco Battalion in Somalia (Ibis I and Ibis II missions), escorted by the 24th Naval Group (
On 16 June 2016, San Marco sailed with Bersagliere, Cigala Fulgosi, Andrea Doria, Carlo Margottini, Etna and Stromboli in the "Flotta Verde" exercise (Great Green Fleet initiative) with the 
The 2005 training campaign was again in the Mediterranean, and this time foreign 12 officer cadets were invited. By the summer of 2006 she was in the Eastern Mediterranean then soon engaged in the Lebanon operation Leonte together with her sisters and the Garibaldi. She also took part in Operation Antica Babilonia.
The summer of 2010 saw a training cruise with the Naval Academy of Livorno students to North American waters, she also took part in an exercise with the USN.
In the summer of 2011 she became tje HQ ships for the Operation "Unified Protector", the NATO intervention in Libya.

The "Bâtiment de Débarquement et de Soutien Logistique" was called in general fleet catalogue (such as in Janes) "San Giorgio Improved": Delivered on 4 September 2014, comm. on 28 March 2015 as Kalaat Béni Abbès (474) it had differences like updated electronics. Under the acronym BDSL and Launched on 8 January 2014 it had Aster 15 self defence SAM located behind the island superstructure, and still kept an OTO Melara 76 mm "Super Rapido" at the bow, but two 25 mm RWS. Capacity was not very different with three landing craft mechanized (LCM), three small landing craft vehicle personnel (LCVP), or one large landing craft personnel (LCP), plus two semi-rigid boats. The hangar is large enough for 15 armoured vehicles, 440 soldiers for a crew of 150.
