The ship is divided into 7 zones, and is equipped with a computerized system for monitoring and decision support in emergency conditions. The ship is divided into 7 zones, and is equipped with a computerized system for monitoring and decision support in emergency conditions. These people have taken such as smoke curtain, the new criteria for stations over breathable air and on the collector ring, arrangements for the disposal of fumes, the relative positions, accessibility and the conformation of local relevance to the Service Safety (COP, COC, area health, control stations), and so forth. See the image below.
The unit is equipped with all the necessary environment to operate in contaminated area by NBC agents (nuclear, bacteriological or chemical).
On board there is a system degaussing (degaussig) fully automated to reduce magnetic anomalies generated by the unit and therefore to reduce the risk due to landmines.
Miscellaneous: The Standard housing are very high, both in terms of space per person than as finishing level housing and services are provided for single or double accommodation for officers and staff of the role marshals, accommodation in four places for staff roles warrant and troops; remain collective "comrade" only for the staff of San Marco Regiment, to embark only for special needs and for limited periods. There are great public spaces, including bar, cinema and gym.
The vessel is covered by 1360 km of cables and 190 cameras. There are 2 cells for food by 400 and 800 m2, 2 deposits for food and 2 kitchens with ovens for the fresh bread . There are also desalinization to make drinking water from the sea.
Particular care was given to the activities of loading, packaging and distribution of food and waste management, liquid and solid with the ristrittive rules MARPOL 73/78 (Marine Pollution) for commercial ships, not mandatory for military ships. The MARPOL 73/78 was designed to minimize pollution of the marine ecosystem (water and air), and covers the possible causes of pollution naval: municipal solid waste and non fuels, gaseous emissions and toxic substances transported .
Aviation facility
Air group: The ship hasn't assigned a fixed air group but is fixed according to the mission, will be a mix of 20-24 short takeoff vertical landingHarrier AV-8B plus 2 (F35B when available) and helicopters EH-101 (including Mk.112 AEW/HEW, Mk.110 ASW/ASV, Mk.410 TTH/utility e Mk.413 ASH), NH-90NFH or TTH and SH3D
Flight-deck: is long 232,6 m and width 34,5 m (surface 6.800+ m2). It has a runway for takeoff short long 183,0 m for 14,2 m, ski-jump with 12° of elevation, a parking area (starboard side) to 10/12 aircraft, 6 spot for helicopters type EH-101 plus a dedicated spot for SAR missions to bow.
Hangar: is long 134,2 m, width 21,0 m e high 7,2 m (8,5 max.). It is connected to the flight deck with 2 McTaggart Scott elevators from 30 tons of which aft an “deck-edge" after the island size 15 m to 14 m, the second forward internal long 21.6 m for 14 m. There are also 2 elevators from 15 tons for ammunition and 2 service elevators from 7 tons. It has tanks 1,500,000 litres of fuel for planes and helicopters. The 2 main elevators do not interfere with the operations of takeoff and landing of aircraft.
Transport capacity: the hangar can be used as a garage for the transport of terrestrial resources, and can contain up to 24 heavy vehicles like tanks Ariete (over 250 meters), or up to 50 vehicles average as the amphibians AAV7 RAM/RS, Centauro B1, Freccia, Dardo (over 423 meters) or up to 100 vehicles average as VTLM Lince, Puma, Defender e VM90 (over 522 meters). The hangar is accessible by 2 ramps from 60 tons posed stern and straight, under the island.
Capacity of amphibious assault:the San Marco regiment, or the new force projection from the sea (FPM) with the Lagunari army, can be landed with 2 assaults of 6 helicoptersEH-101(2 companies fully equipped) or with the help the 3 LCVP, 3 inflatables and a spear.
Program / history: a mid 80 the General Staff of the Navy decided to base navy on two STOVL carriers,Garibaldi, just entered into service in 1985, and a second similar unit whose entrance was in line for the 1994 or so. For reasons of an economic, political (the Garibaldi was carried out with features from cruiser), the project was slipping and the subsequent collapse of the Berlin Wall was changing needs of MMI. In the nineties, the project was further amended and oriented towards an anphibious unity similar to American Wasp but reduced in scale. The project again taken the path of pure STOVL carrier in the late nineties and in 2000 was finally approved. Despite the latest change of course the ship has maintained some characteristics from amphibious assault ship as boats under the stern deck and ramps for boarding means land from the stern and upright in the island. The ship was also built as a Landing Platform Helicopter (LPH). The hangar and closed type and size of 134 m for 21 and it can accommodate (officially) 12 helicopters or 8 aircraft. For more information on the development of the project see the following page.
The cutting of the first steel occurred on July 17, 2001. The launch of the middle and aft of the ship occurred on July 20, 2004 in Riva Trigoso. Following this portion of the vessel was towed to Muggiano, where it was built bow. In November were welded the two sections. The Cavour is floating in its entirety, from mid-December 2004. The first test at sea in motion just occurred on December 22, 2006. During 2007 took place various tests at sea but the flight deck was not available for landing aircraft, as has been seen in television service of RAI 1 in mid-August.
In November started the first tests of landing by the EH-101 and AV-8B were onboard for a few days to check the suitability of the flight deck and dell'hangar. They made landings and takeoffs day and night.
In October 2007 it was decided boarding a piece 76/62, reconditioned and updated with the latest systems, previously embarked on ship Audace. It remains yet to find the second piece to be mounted on the platform already prepared. In November 2007 it was decided the purchase and installation of 2 systems Dardo-F instead of E, for control of artillery pieces from 76/62.
Official commission of the carrier Cavour onto the Italian Navy took place on 27 March 2008.Then it is expected that the unit remains at the site of Muggiano to complete the installation of the combat system planned for summer 2008.
The inclusion in the fleet is scheduled in Summer 2008 and full operation capability (FOC) in 2009.

Using the ship:
Command Ship:
Using C4I the ship can provide command center that due Italian or NATO operating theater kindly to monitor actions naval, air or land.
Air Defense:the ship can provide high air cover to a naval group, which is the central element, using its aircraft to patrol remote, helicopters HEW for control over the horizon in addition to its long-range radar scope. With the use of data connections can work in unison with the unit basis, especially with the AAW destroyer.
Force Projection: to provide air support for amphibious landings or land operations, air strikes carried out with part of its fighter
Control of the Sea: it can perform anti-submarine missions embarking a number of ASW helicopters, sea control missions or anti-surface mission capabilities of its aircraft and escort unit.
International Missions:working to support peace-keeping missions, including the transport of troops or material
Civil Support:evacuation of non-combatants and humanitarian support in the event of natural disasters to provide logistical coordination or medical support
Cost: the total cost of the ship should be set at 1.5 billion euros, including combat system. The first contract (NUM 1) between the General Direction for naval armaments (NAVARM) and the company Fincantieri for the acquisition, valued at about 900 million of euros, was signed in November 2000. A second contract (NUM 2.1) for about 230 million euros was signed in 2002 for a good part of the electronic systems. The third contract (NUM 2.2), also for electronics on board, was signed in 2003 with a value of 150 million euros. The acquisition of the ship was divided into nearly a decade of defense budgets and even with the use of funds from the Ministry of Economic Development (MSE), here's a summary table::
before 2001 => <50 milion of euros
2001 => 35 million euros
2002 => 78 milion euros
2003 => 92 milion euros
2004 => 185,9 milion euros
2005 => 177,5 milion euros
2006 => 25,1 milion euros + MSE
2007 => 211,2 milion euros
2008 => 150,3 milion euros
