Roma was the third Vittorio Veneto-class battleship of Italy's Regia Marina (Royal Navy). The construction of both Roma and her sister ship Impero was due to rising tensions around the world and the navy's fear that only two Vittorio Venetos, even in company with older pre-First World War battleships, would not be enough to counter the British and French Mediterranean Fleets. While the force was in the Strait of Bonifacio, Dornier Do 217s of the German Luftwaffe's specialist wing KG 100 armed with Fritz X radio-controlled bombs sighted the force. The first attack failed, but the second dealt Italia (ex-Littorio) and Roma much damage. The hit on Roma caused water to flood two boiler rooms and the aft engine room, leaving the ship to limp along with two propellers, reduced power, and arc-induced fires in the stern of the ship. Shortly thereafter, another bomb slammed into the ship and detonated within the forward engine room, causing catastrophic flooding and the explosion of the #2 main turret's magazines, throwing the turret itself into the sea. Sinking by the bow and listing to starboard, Roma capsized and broke in two, carrying 1,393 men including Bergamini down with her.
