Japanese aircraft carrier Shinano Shinano (信濃 ) , was an aircraft carrier built by the Imperial Japanese Navy (IJN) during World War II, the largest such built up to that time. Laid down in May 1940 as the third of the "Yamato"-class battleship s, "Shinano"' s partially complete hull was ordered to be converted to a carrier following Japan's disastrous loss of four fleet carriers at the Battle of Midway in mid-1942.

Yamato-class battleship The "Yamato"-class battleships (大和型戦艦 , Yamato-gata senkan ) were battleships of the Imperial Japanese Navy (IJN) constructed and operated during World War II. Displacing 72000 LT at full load, the vessels were the heaviest battleships ever constructed. The class carried the largest naval artillery ever fitted to a warship, nine 460-millimetre (18.1 in) naval guns, each capable of firing 1460 kg shells over 42 km . Two battleships of the class ("Yamato" and "Musashi" ) were completed, while a third ("Shinano" ) was converted to an aircraft carrier during construction.

Katori-class battleship The "Katori" class (香取型戦艦 , Katori-gata senkan ) was a two-ship class of pre-dreadnought battleships built for the Imperial Japanese Navy (IJN) in the early 1900s. As Japan lacked the industrial capacity to build such warships itself, they were designed and built in the UK. They were the last battleships to be built for Japan at overseas shipyards, and the last to be equipped with a ram. The ships were delivered after the end of the Russo-Japanese War of 1904–05. They saw no action during World War I, although both were present when Japan joined the Siberian Intervention in 1918. They were disarmed and scrapped in 1923–25 in accordance with the terms of the Washington Naval Treaty of 1922.

Kaiser-class battleship The "Kaiser" class was a class of five battleships that were built in Germany prior to World War I and served in the Imperial German Navy during the war. They were the third class of German dreadnoughts, and the first to feature turbine engines and superfiring turrets. The five ships were "Kaiser" , "Friedrich der Grosse" , "Kaiserin" , "Prinzregent Luitpold" , and "König Albert" . As was usual for German battleships of the period, the "Kaiser" class mounted main guns that were smaller than those of their British rivals: 30.5 cm , compared to the 34.3 cm guns of the British "Orion" class .

5&quot;/25 caliber gun The 5"/25 caliber gun (spoken "five-inch-twenty-five-caliber") entered service as the standard heavy anti-aircraft (AA) gun for United States Washington Naval Treaty cruisers commissioned in the 1920s and 1930s. The goal of the 5"/25 design was to produce a heavy AA gun that was light enough to be rapidly trained manually. The gun was also mounted on pre-World War II battleships and aircraft carriers until replaced by the standard dual-purpose 5"/38 caliber gun, which was derived from the 5"/25 and was similar except for the barrel length. Guns removed from battleships were probably converted for submarine use by late 1943, while a purpose-built variant for submarines was available in mid-1944, and was widely used by them. United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 25 calibers long (that is, for a 5" bore and a barrel length of 25 calibers, 5" x 25 = 125", or about 3.2 meters).

Nagato-class battleship The "Nagato"-class battleships (長門型戦艦 , Nagato-gata senkan ) were a pair of dreadnought battleships built for the Imperial Japanese Navy (IJN) during World War I, although they were not completed until after the end of the war. "Nagato" , the lead ship of the class, frequently served as a flagship. Both ships carried supplies for the survivors of the Great Kantō earthquake in 1923. They were modernized in 1933–36 with improvements to their armor and machinery and a rebuilt superstructure in the pagoda mast style. "Nagato" and her sister ship "Mutsu" briefly participated in the Second Sino-Japanese War in 1937 and "Nagato" was the flagship of Admiral Isoroku Yamamoto during the attack on Pearl Harbor on 7 December 1941 that began the Pacific War.

Japanese battleship Hatsuse Hatsuse (初瀬 , Hatsuse ) was a "Shikishima"-class pre-dreadnought battleship built for the Imperial Japanese Navy by the British firm of Armstrong Whitworth in the late 1890s. The ship participated in the early stages of the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war. She was involved in the subsequent operations until she struck two mines off Port Arthur in May 1904. The second mine detonated one of her magazines and "Hatsuse" sank almost immediately afterwards with the loss of over half her crew.

Japanese battleship Yamato Yamato (大和 ) was the lead ship of the "Yamato" class of Imperial Japanese Navy World War II battleships. She and her sister ship, "Musashi" , were the heaviest battleships ever constructed, displacing 72,800 tonnes at full load and armed with nine 46 cm (18.1 inch) 45 Caliber Type 94 main guns, which were the largest guns ever mounted on a warship. Neither ship survived the war.

I-400-class submarine The I-400"-class submarine (伊四百型潜水艦 , I-yon-hyaku-gata sensuikan ) Imperial Japanese Navy (IJN) submarines were the largest submarines of World War II and remained the largest ever built until the construction of nuclear ballistic missile submarines in the 1960s. The IJN called this type of submarine Sentoku" type submarine (潜特型潜水艦 , Sen-Toku-gata sensuikan, "Submarine Special" ) . The type name was shortened to Toku-gata Sensuikan (特型潜水艦 , Special Type Submarine ) . They were submarine aircraft carriers able to carry three Aichi M6A "Seiran" aircraft underwater to their destinations. They were designed to surface, launch their planes, then quickly dive again before they were discovered. They also carried torpedoes for close-range combat. They are considered the strategic predecessors to today’s ballistic submarines, especially to the Regulus missile program begun about a decade after World War II.

15.5 cm/60 3rd Year Type naval gun The 15.5 cm/60 3rd Year Type (60口径三年式15.5cm3連装砲 , 60 kōkei sannenshiki 15.5 centi sanrensōhō ) was a dual-purpose naval gun used by the Imperial Japanese Navy on the "Yamato"-class battleship s as secondary armament in four triple turrets, the "Mogami"-class cruiser s in five triple turrets, the "Tone"-class cruiser s in five triple turrets (The Mogami & Tone class were later converted to five twin 20 cm/50 3rd Year Type naval gun turrets) and on the light cruiser "Ōyodo" in two triple turrets. They were also deployed on 60° single mounts as coastal defense guns in the Tokyo Bay area. Construction was of the monobloc type with autofretting and used a Welin breech block mechanism which could be operated either hydraulically or by hand. Their slow rate of fire, limited elevation and slow traverse made them unsuitable for the AA role, but they were an excellent anti-ship weapon.

Japanese destroyer Hayate (1925) The Japanese destroyer "Hayate" (疾風 , "Gale" ) was one of nine "Kamikaze"-class destroyers built for the Imperial Japanese Navy (IJN). During the Pacific War, she was sunk by American coast-defense guns during the Battle of Wake Island in December 1941, the first Japanese warship to be lost during the war. Only a single man of her crew was rescued.

320 mm Model 1934 naval gun The 320 mm naval gun was the main battery gun used to modernize Italy's World War I battleships for service during World War II. The guns were manufactured by boring out and relining the battleships' original 12"/46 (30 cm) built-up guns and modifying the turrets to increase elevation above the original 20°  maximum. Each ship carried two 548-tonne twin turrets and two 745-tonne triple turrets. All guns used pneumatically operated side-swing Welin breech blocks. Each barrel could fire two rounds per minute.

Mogami-class cruiser The "Mogami" class (最上型 ) were 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 refused to comply any longer with that agreement, all four ships were rearmed with larger guns and were reclassified as heavy cruisers. All four fought in World War II and were sunk.
