Italia (1880)

The frontal view shows the flying bridge, the elevated forward control and navigation house, the sponsons, and the rounded hull shape.

From this deck plan the redoubt’s diagonal arrangement is clear. There was an armoured deck just below waterline level, but no citadel or side armour.

A novel battleship design, with four very large guns and no side armour, in many ways Italia was a forerunner of the battlecruiser. For a few years it held the prestige position of the largest and fastest battleship in the world.

The Kingdom of Italy was declared in 1861 and from the start it had difficult relations with the French and the Austrians. For Italy with its long coasts and numerous islands, a naval force was a prime necessity, and by 1866 it had fought one of the first ‘modern’ sea battles, against the Austrian Navy at Lissa in the Adriatic Sea. That was a defeat despite superior numbers on the Italian side, and drove the Italians to further expansion of their fleet.

Fast and powerful

Laid down at Castellamare in 1877 and launched in 1880, Italia took Brin’s revolutionary design of Duilio (1876) to an extreme. The brief was for a very fast ship, heavily-armed, which could also carry a large number of troops (at the time, France and Italy were on the verge of war over Tunis, on the south coast of the Mediterranean Sea). As with Duilio, the guns were mounted in echelon, but the main armament of Italia and its sister ship Lepanto was of even heavier calibre, four 432mm (17in) guns each weighing 93 tonnes (103 tons), firing shells of 907kg (2000lb). The guns were mounted in a huge barbette of oval shape extending beyond the sides, forming an armoured redoubt set diagonally across the hull. Unlike the British Inflexible, it had a high freeboard, 7.6m (25ft), offering more of a target to an enemy. The sides carried no armour, but Italia relied on the power of its guns, and its high speed, to avoid attack. Six funnels in sets of three, linked by high catwalks with the conning tower, a lofty central mast, and a large curved crane on the afterdeck, gave Italia a unique appearance. One of the few more traditional features was an ‘admiral’s walk’ around the curved stern.


The ship was built largely of steel, rather than iron. Internally it had the now-standard armoured deck, curving upwards slightly from the sides 1.83m (6ft) below the waterline, but above it a cellular raft ran the entire length of the ship. The space between them was lined laterally with cork-filled watertight cells separating the hull plating from an inner cofferdam on each side, and two transverse levels, one of empty cells, with coal storage space below. A double bottom was also fitted.

One novel feature of Duilio, not maintained on the new ship, was a stern compartment for a torpedo boat, secured by watertight doors. Italia also had space to hold an infantry division of 10,000 men and its equipment for the relatively short Mediterranean crossing. The main guns could be independently trained and aimed, but as with other very large guns of the time, the rate of fire was slow, no more than one round every four or five minutes.

Construction of Italia and Lepanto stretched Italy’s new warship-building resources, and the Italian government did not proceed to enlarge its battlefleet further. But the size, speed and general innovation of these Italian capital ships had a major impact on ship design and naval planning in both the British and the French navies. Sir Nathaniel Barnaby, Britain’s chief naval designer, observed that ‘We must … regard the first-class ironclad as … being of over 14,000 tons if we accept the reasonings of the Italian architects and the expression of their ideas in the Italia and Lepanto’. In the mid-1880s British designers were still mulling over the kind of ship ‘most suitable for meeting the Italia’. In this way the Italian contribution was to push the greater naval powers towards greater size.


Between 1905 and 1908 Italia was rebuilt, losing two funnels and with the tall single mast replaced by two, forward and aft of the funnels. By this time battleship development had caught up and moved on. Improved armour had disproved Brin’s theory that gun-power had made side-armour pointless, and the formidable guns were sadly out of date. By the 1890s the ship really ranked with armoured cruisers. The secondary armament was changed and reduced in quantity. In 1909–10 it was used for torpedo training.

Still in commission during World War I, but renamed as Stella d’Italia, it was based at Taranto and Brindisi for gunnery training until 1917, when it was disarmed and transferred to the mercantile marine as a grain transport. It was returned to the Regia Marina in 1921, but was almost immediately sold for scrapping.
