Pola was the forth and last of the Zara-class cruisers built for the Italian Regia Marina. Unlike her three sisters (Zara, Gorizia and Fiume), she was completed as a flag ship, with a larger conning tower for the admiral and his staff. Launched on 5 December 1931, she was commissioned into the Italian Navy on 31 December 1932.
During The Second World War, she participated in the battles of Calabria (July 1940) and Cape Spartivento (November 1940). During the Battle of Cape Matapan (27-29 March 1941), Pola was disabled by an aerial torpedo. Zara and Fiume were sent to help and escort her to port. During the night, the cruisers were surprised by the British Royal Navy fleet, centred on the battleships HMS Warspite, Valiant and Barham. The battleships overwhelmed Zara, Fiume and two destroyers. The British considered towing Pola to Alexandria, but the proximity to Italian airfields and the approaching dawn prevented this. Instead, she was sunk by torpedoes from the destroyers HMS Jervis and Nubian.
The lead ship of her class of dreadnought battleships for the US Navy, USS South Carolina (BB-26) was launched on 11 July 1908 and commissioned on 1 March 1910. The first dreadnought battleship built for the US Navy, she incorporated several revolutionary aspects, primarily the superfiring guns of her main battery.
USS South Carolina spent much of her career patrolling the east coast of the USA. During the Mexican Revolution, she took part in the United States occupation of Veracruz.
She was mostly used as a training ship after the US entered World War One, while also performing convoy escort duty. Post war she repatriated US Servicemen from Europe.
Along with her sister ship USS Michigan, she was scrapped under the terms of the Washington Treaty. Before being scrapped, the hulk was used to test the effectiveness of anti-torpedo bulges. South Carolina was decommissioned on 15 December 1922 and sold for scrap in 1924.

The lead ship of her class of four heavy cruisers for the Italian navy, Zara was launched on 27 April 1930. Commissioned into the Regia Marina on 20 October 1931, she took an active part in naval operations in the Mediterranean along with her sisters Fiume, Pola and Gorizia.
During the Battle of Cape Matapan, Zara and Fiume were sent to protect Pola which had been hit by an aerial torpedo. During the night, the three cruisers were surprized by a force of three British battleships (HMS Warspite, Valiant and Barham). All three heavy cruisers were lost.
