Zara was a heavy cruiser built for the Italian Regia Marina (Royal Navy), the lead ship of the . Named after the Italian city of Zara (now Zadar, Croatia), the ship was built at the Odero-Terni-Orlando shipyard beginning with her keel laying in July 1928, launching in April 1930, and commissioning in October 1931. Armed with a main battery of eight guns, she was nominally within the limit imposed by the Washington Naval Treaty, though in reality she significantly exceeded this figure.

Zara saw extensive service during the first two years of Italy's participation in World War II, having taken part in several sorties to catch British convoys in the Mediterranean as the flagship of the 1st Division. She was present during the Battle of Calabria in July 1940, the Battle of Taranto in November 1940, and the Battle of Cape Matapan in March 1941. In the last engagement, Zara and her sister ships and were sunk in a close-range night engagement with three British battleships. Most of her crew, 783 officers and sailors, including the divisional commander Admiral Carlo Cattaneo and the ship's commanding officer Luigi Corsi, were killed in the sinking.

Zara was long overall, with a beam of and a draft of . She displaced at full load, though her displacement was nominally within the restriction set in place by the Washington Naval Treaty. Her power plant consisted of two Parsons steam turbines powered by eight oil-fired Yarrow boilers, which were trunked into two funnels amidships. Her engines were rated at and produced a top speed of . She had a crew of 841 officers and enlisted men.Template:Sfn

She was protected with an armor belt that was thick amidships. Her main deck was thick and there was a secondary deck thick over the main one. The gun turrets had 150 mm thick plating on the faces and the barbettes they sat in were also 150 mm thick. The main conning tower had 150 mm thick sides.Template:Sfn

Zara was armed with a main battery of eight [[203 mm /53 Italian naval gun|Template:Cvt Mod 29]] 53-caliber guns in four gun turrets. The turrets were arranged in superfiring pairs forward and aft. Anti-aircraft defense was provided by a battery of sixteen 47-cal. guns in twin mounts, four Vickers-Terni 40 mm/39 guns in single mounts and eight guns in twin mounts. She carried a pair of IMAM Ro.43 seaplanes for aerial reconnaissance; the hangar was located in under the forecastle and a fixed catapult was mounted on the centerline at the bow.Template:SfnTemplate:Sfn

ZaraTemplate:'s secondary battery was revised several times during her career. Two of the 100 mm guns and all of the 40 mm and 12.7 mm guns were removed in the late 1930s, and eight 54-cal. guns and eight guns were installed in their place. Two 15-cal. star shell guns were added in 1940.Template:Sfn

ZaraTemplate:'s keel was laid down on 4 July 1928 at the Odero-Terni-Orlando (OTO) shipyard at Muggiano, La Spezia; she was launched on 27 April 1930, and her construction was completed on 20 October 1931, when she was commissioned into active service.Template:Sfn During sea trials, Zara reached a speed of , but this was with the ship's machinery forced to give . This was not representative of in-service performance, however, and normal maximum at-sea speed was about .Template:Sfn The ship was presented with her battle flag in her namesake city, now Zadar, Croatia.Template:Sfn

In August 1932, Zara took part in fleet training exercises in the Gulf of Naples; King Victor Emmanuel III came aboard the ship on the 13th. She became the flagship of the First Naval Squadron in September. She took part in a naval review held for Benito Mussolini in the Gulf of Naples on 6–7 July 1933. Zara participated in another review on 27 November 1936, and Victor Emmanuel III, his son Umberto, Prince of Piedmont, Mussolini, and the Regent of Hungary, Miklós Horthy, all came aboard the ship. Another fleet review was held for the German Field Marshal Werner von Blomberg, the German minister of defense, on 7 June 1937. On 16 September, the commander of the squadron transferred his flag to the battleship . A final peacetime naval review took place on 5 May 1938, held for the visit of Adolf Hitler.Template:Sfn

On 7 March 1939, Zara and her sister ships sortied from Taranto to intercept a squadron of Republican warships—three cruisers and eight destroyers—attempting to reach the Black Sea. The Italian ships were ordered not to open fire but merely to try to impede the progress of the Spanish ships and force them to dock at Augusta, Sicily. The Spanish commander refused and instead steamed to Bizerte in French Tunisia, where his ships were interned. A month later, from 7 to 9 April, Zara supported the Italian invasion of Albania without incident. She was in port in Genoa for Navy Day on 10 June; she spent the rest of 1939 uneventfully.Template:Sfn

World War II

At Italy's entrance into the Second World War on 10 June 1940, Zara was assigned to the 1st Division of the 1st Squadron, as the flagship of Rear Admiral Matteucci. The division also included her sisters and and the four s.Template:Sfn At the time, the division was based in Taranto; the ships were immediately sent to patrol off the island of Crete, and on 11–12 June, the ships were attacked by an unknown submarine, which the destroyers unsuccessfully counterattacked. On 21 June, Zara and the rest of the division were transferred to Augusta, Sicily to be better positioned to intercept Allied convoys in the Mediterranean. The following day, the 1st Division joined a patrol with the 2nd and 3rd Divisions, though they failed to find any Allied vessels. Zara was present at the Battle of Calabria on 9 July. On 30 July, the 1st Division escorted a convoy to Benghazi and Tripoli in Italian Libya, arriving back in Augusta on 1 August. Gunnery training off Naples followed on 16 August, and on 29 August the ships left Naples for Taranto, arriving the next day. On the 31st, the 1st Division sortied to intercept the British convoys in Operation Hats, though the Italian fleet broke off the attack without encountering the merchant ships.Template:Sfn

Zara returned to Taranto, and was present during the Battle of Taranto on the night of 11–12 November. She was undamaged during the British attack. In the aftermath of the attack, the Italian command decided to disperse the fleet to protect them from further attacks; Zara was sent to La Spezia for periodic maintenance on the 12th. The work lasted until 9 December, and she steamed south to Naples the following day. British bombing of the port four days later forced the Italians to again relocate the cruisers, sending them first to La Maddalena in Sardinia on 15 December and then back to Naples on the 19th. They stayed there for three days before proceeding to Taranto on 22 December.Template:Sfn That month, Admiral Carlo Cattaneo came aboard Zara as the new commander of the division.Template:Sfn Training exercises with Gorizia followed on 29 January and continued into the next month, when Pola joined them on 13 February. In mid March, Zara, Pola, and Fiume conducted gunnery training in the Gulf of Taranto. By this time, Pola had replaced Gorizia in the 1st Division.Template:Sfn

Battle of Cape Matapan

The Italian fleet made another attempt to intercept a British convoy in the eastern Mediterranean south of Crete in late March. This operation resulted in the Battle of Cape Matapan on 27–29 March. For most of the daytime engagement, Zara and the rest of the 1st Division were stationed on the disengaged side of the Italian fleet, and so did not see action during this phase. Vittorio Veneto was torpedoed by British aircraft from the carrier and was forced to withdraw, and the 1st Division remained on the port side of the Italian fleet to screen against another possible British attack.Template:Sfn A second British airstrike later on the 28th failed to locate the retiring Vittorio Veneto and instead scored a single torpedo strike on Pola, hitting her amidships on her starboard side. In the confusion of the attack, Pola had nearly collided with Fiume and had been forced to stop, which had prevented her from taking evasive action. The damage filled three compartments with water and disabled five of her boilers and the main steam line that fed the turbines, leaving her immobilized.Template:SfnTemplate:Sfn

Admiral Iachino, the fleet commander, was unaware of PolaTemplate:'s plight until 20:10; upon learning of the situation he detached Zara, Fiume, and four destroyers to protect Pola. At around the same time, the British cruiser detected Pola on her radar and reported her location.Template:Sfn The British fleet, centered on the battleships , , and , was at this point only away.Template:Sfn The British ships, guided by radar, closed in on the Italians; at 22:10, Pola was about from Valiant. Lookouts on the crippled Italian cruiser spotted shapes approaching and assumed them to be friendly vessels, so they fired a red flare to guide them. Almost twenty minutes later, the British illuminated first Zara and then Fiume with their searchlights; the British battleships obliterated Zara, Fiume, and two destroyers in a point-blank engagement.Template:Sfn Zara had been hit by four broadsides from Warspite and five more from Valiant in the span of just a few minutes. The destroyer launched torpedoes at the crippled Zara and scored at least one hit. The destroyer launched four more torpedoes with unknown results.Template:Sfn

The British battleships then turned away to avoid a torpedo attack from the remaining destroyers. Zara, by now burning furiously, remained afloat and drifted near the immobilized Pola. ZaraTemplate:'s commander decided at 02:00 that his ship could not be saved, and so ordered the crew to scuttle the ship.Template:Sfn At around the same time, the destroyer arrived on the scene and fired three torpedoes at Zara.Template:Sfn The demolition charges exploded in the magazines at 02:30, and within ten minutes, the ship capsized and sank.Template:Sfn Most of her crew, some 783 men including Cattaneo, were killed in the sinking.Template:SfnTemplate:Sfn Zara was formally stricken from the naval register on 18 October 1946.Template:Sfn
