''Pola'' was a heavy cruiser of the Italian ''Regia Marina'' (Royal Navy). She was built in the Odero-Terni-Orlando shipyard in Livorno in the early 1930s and entered service in 1932. She was the third of four ships in the class, which also included , , and . ''Pola'' was built as a flagship with a larger conning tower to accommodate an admiral's staff. Like her sisters, she was armed with a battery of eight guns and was capable of a top speed of . ''Pola'' initially served as the flagship of the 2nd Squadron, and in 1940 she led the squadron during the battles of Calabria and Cape Spartivento, in July and November, respectively.

The ship took part in the Battle of Cape Matapan in late March 1941. During the battle, she was disabled by a British airstrike. Later, in a fierce night engagement in the early hours of 29 March, ''Pola'', ''Zara'', ''Fiume'', and two destroyers were sunk by the British Mediterranean Fleet with heavy loss of life. ==Design== (詳細は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.〔Gardiner & Chesneau, p. 292〕 ''Pola'' was designed to function as a squadron flagship, and so her forward superstructure was larger than that of her sisters, and was faired into the forward funnel.〔 She was protected with a armored belt that was thick amidships. Her armor deck was thick in the central portion of the ship and reduced to at either end. 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.〔 ''Pola'' was armed with a main battery of eight 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 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.〔〔Brescia, p. 76〕 ''Pola''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. starshell guns were added in 1940.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Italian cruiser Pola」の詳細全文を読む スポンサード リンク
