The battlecruiser was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers were built, they were increasingly used alongside the better-protected battleships.
The armored cruiser was a type of warship of the late 19th and early 20th centuries. It was designed like other types of cruisers to operate as a long-range, independent warship, capable of defeating any ship apart from a battleship and fast enough to outrun any battleship it encountered.
USS Hawaii (CB-3) was intended to be the third member of the Alaska-class large cruisers. It was the first United States Navy ship to be named after the then-Territory of Hawaii. Because Hawaii's construction was delayed by higher-priority ships like aircraft carriers, her keel was not laid until December 1943, about two years after her sister ship Guam.
HMS Black Swan, was the name ship of the Black Swan-class sloops of the Royal Navy. This class was admired for its sea-going qualities.
Kongō was a warship of the Imperial Japanese Navy during World War I and World War II. She was the first battlecruiser of the Kongō class, among the most heavily armed ships in any navy when built. Her designer was the British naval engineer George Thurston, and she was laid down in 1911 at Barrow-in-Furness in Britain by Vickers Shipbuilding Company. Kongō was the last Japanese capital ship constructed outside Japan. She was formally commissioned in 1913, and patrolled off the Chinese coast during World War I.
The Mogami class (最上型) was a ship class of four cruisers built for the Imperial Japanese Navy (IJN) during the 1930s. They were initially classified as light cruisers under the weight and armament restrictions of the London Naval Treaty. After Japan abrogated that agreement, all four ships were rearmed with larger guns and reclassified as heavy cruisers. All participated in World War II and were sunk.
Pre-dreadnought battleships were sea-going battleships built between the mid- to late- 1880s and 1905, before the launch of HMS Dreadnought in 1906. The pre-dreadnought ships replaced the ironclad battleships of the 1870s and 1880s. Built from steel, protected by case-hardened steel armour, and powered by coal-fired triple-expansion steam engines, pre-dreadnought battleships carried a main battery of very heavy guns in fully enclosed rotating turrets supported by one or more secondary batteries of lighter weapons.
Satsuma (薩摩) was a semi-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the first decade of the 20th century. Lead ship of her class, she was the first battleship built in Japan. She was named for Satsuma Province, now a part of Kagoshima prefecture. The ship saw no combat during World War I, although she led a squadron that occupied several German colonies in the Pacific Ocean in 1914. Satsuma was disarmed and sunk as a target in 1922–1924 in accordance with the terms of the Washington Naval Treaty of 1922.
Coastal defence ships were warships built for the purpose of coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited blue-water capabilities; others operated in rivers.
Maya (摩耶) was one of four Takao-class heavy cruisers, active in World War II with the Imperial Japanese Navy (IJN). These were the largest and most modern cruisers in the Japanese fleet, and were intended to form the backbone of a multipurpose long-range strike force. These ships were fast, powerful and heavily armed, with enough firepower to hold their own against any cruiser in any other navy in the world. Her sister ships were Takao, Atago and Chōkai.
The Battle of Ko Chang took place on 17 January 1941 during the Franco-Thai War in which a flotilla of French warships attacked a smaller force of Thai vessels, including a coastal defence ship. The battle resulted in a tactical victory by the French Navy over the Royal Thai Navy although the strategic result is disputed. The Japanese intervened diplomatically and mediated a ceasefire.
The Insect-class gunboats were a class of small, but well-armed Royal Navy ships designed for use in shallow rivers or inshore. They were intended for use on the Danube against Austria-Hungary. The first four ships—Gnat, Mantis, Moth and Tarantula—were first employed during the Mesopotamian Campaign of the First World War on the Euphrates and Tigris rivers.
The Kasuga-class cruiser was a class of two armored cruisers of the Imperial Japanese Navy (IJN) based on the Giuseppe Garibaldi-class cruisers developed by Italy at the end of the 19th century.
Design B-65 was a class of Super Type A cruisers planned by the Imperial Japanese Navy (IJN) before and during World War II. As envisioned by the IJN, the cruisers were to play a key role in the Night Battle Force portion of the "Decisive battle" strategy which Japan hoped, in the event of war, to employ against the United States Navy.
HTMS Thonburi was a coastal defence ship of the Royal Thai Navy.
The St. Louis-class cruisers were a class of three cruisers that served in the United States Navy at the beginning of the 20th century. Authorized in fiscal year 1901 by an Act of Congress of 7 June 1900 as part of the naval buildup touched off by the Spanish–American War, the St. Louis-class cruiser initially began as an improved Olympia. However, during the design phase, decisions were made that increased the size of the vessel from 6,000 long tons (6,100 t) to 9,700 long tons (9,900 t), including adding protection that resulted in the designation "semi-armored cruiser". This led to a larger power plant, and other decisions were made to try to increase speed and range, such as using smaller 6-inch (152 mm) guns instead of 8-inch (203 mm) guns, and adding coal capacity. The completed ship at 9,700 long tons was the same displacement as a full armored cruiser without the same armor. One reference describes the class as "among the earliest well-documented examples of creeping growth in warship design".
The Giuseppe Garibaldi-class cruisers were a class of ten armoured cruisers built in Italy in the 1890s and the first decade of the 20th century. The ships were built for both the Royal Italian Navy and for export. With the class being named for Italian unifier and nationalist Giuseppe Garibaldi.
HTMS Sri Ayudhya was a coastal defence ship of the Royal Thai Navy. It was in service from 1938 to 1951, being active during the Franco-Thai war in which its sister ship HTMS Thonburi was heavily damaged in the Battle of Ko Chang. Sri Ayudhya later served as flagship of the navy until it was sunk as a result of fighting in the Manhattan Rebellion.
The Maya class was a four-ship class of gunboats of the early Imperial Japanese Navy.
The Trad class was a class of nine torpedo boats built for the Royal Thai Navy in the 1930s by the Italian shipbuilder Cantieri Riuniti dell'Adriatico. They entered service between 1935 and 1938. Two of the ships were sunk (and a third badly damaged by French warships at the Battle of Ko Chang in 1941, but the remaining seven ships had long careers, remaining in service until the 1970s.
