Batteria Antinave SR311 was an Italian coastal artillery battery located on the island of Sardinia. The designation 'Antinave' indicates its primary function as an anti-ship battery, designed to engage naval targets. The 'SR' prefix commonly refers to 'Salvo Rapido' (Rapid Salvo), a type of Italian coastal gun emplacement from the World War II period. Its position in Sardinia placed it within a critical defensive network for controlling maritime approaches in the central Mediterranean.
During World War II, Italy constructed extensive coastal fortifications along its coastline and occupied territories to protect against Allied naval incursions and amphibious landings. Sardinia, with its long coastline and strategic ports like Cagliari and La Maddalena, was heavily fortified. Batteries like SR311 would have typically been equipped with large-caliber naval guns, often repurposed from older warships or specifically designed for coastal defense, housed in reinforced concrete casemates or open mounts.
The specific armament, crew complement, and exact construction details for SR311 are not confirmed in the available sources. These batteries were part of the broader Regia Marina (Royal Italian Navy) coastal defense strategy. After the war, many such installations were decommissioned, with some positions later repurposed or left as abandoned military heritage sites. The current physical state of the SR311 battery structures at the given coordinates is not documented in the provided search results.
