Portland-class heavy cruiser 波特兰级重型巡洋舰

Attention: This ship is not a decoration, but a vehicle that you can really drive on the sea.

The Portland class of heavy cruisers was a class of ships designed and constructed by the United States Navy in 1930. The two ships of the class, Portland and Indianapolis, saw extensive service during the Pacific War in World War II.

Designed as a modification over the previous Northampton-class cruiser, the Portland class displaced just under 10,000 long tons (10,000 t) and featured heavier armor and armament than previous cruisers. Featuring 8"/55 caliber guns and designed to function as fleet flagships, the Portland class were intended to fix problems with armament and armor that had been a weakness of preceding U.S. cruisers. These designs were carried over to the following New Orleans class, to which six intended Portland cruisers were converted, three of which were already mid-construction.

Portland served in many engagements including the Battle of Coral Sea, the Battle of Midway and the Guadalcanal Campaign, where she was severely damaged but nonetheless able to return to service. She later fought in the Battle of Leyte Gulf and the Battle of Okinawa. Indianapolis served as a fleet flagship for much of the war and fought in the Battle of Philippine Sea and the Battle of Iwo Jima. On 30 July 1945, after transporting components for the nuclear weapons Little Boy and Fat Man from the United States, she was torpedoed by the Japanese submarine I-58. Due to a series of errors and miscommunications her loss was not discovered for several days, and only 316 of her 1,195 crew survived – the greatest single loss of life at sea, from a single ship, in the history of the U.S. Navy.

请注意：这艘船不是装饰物，而是真正可以在海上开的载具

波特兰级重型巡洋舰是美国海军于 1930 年设计并建造的一类舰艇。该级的两艘舰艇“波特兰”号和“印第安纳波利斯”号在第二次世界大战期间的太平洋战争中服役广泛。

波特兰级巡洋舰是在前一级的诺森伯兰级巡洋舰基础上改进而来，排水量略低于 10000 英长吨（10000 吨），其装甲和武器装备比之前的巡洋舰更重。该级舰配备 8 英寸 55 倍径火炮，旨在作为舰队旗舰使用，意在解决此前美国巡洋舰在武器装备和装甲方面的不足。这些设计被延续到了后续的新奥尔良级巡洋舰上，原本计划建造的六艘波特兰级巡洋舰中有三艘已开工建造，其余三艘被改装成了新奥尔良级。

波特兰号参加了多次战斗，包括珊瑚海战役、中途岛战役和瓜达尔卡纳尔战役，在瓜达尔卡纳尔战役中，该舰严重受损但仍能重返战场。后来，它又参加了莱特湾战役和冲绳战役。印第安纳波利斯号在战争期间大部分时间担任舰队旗舰，并参加了菲律宾海战役和硫磺岛战役。1945 年 7 月 30 日，在从美国运送制造原子弹“小男孩”和“胖子”的部件后，该舰被日本潜艇 I-58 发射的鱼雷击中。由于一系列错误和沟通不畅，其沉没数日后才被发现，舰上 1195 名船员中仅有 316 人生还——这是美国海军历史上单艘舰艇在海上造成的最大单次人员伤亡。
