Type 97 Torpedo
The Type 97 was a diameter torpedo used by the Imperial Japanese Navy during World War II. Intended for use with Japan's ''Kō-hyōteki''-class midget submarines, the torpedo was based on the 24-inch diameter Type 93 "Long Lance" used by Japanese surface vessels, but redesigned to meet the smaller 18-inch physical dimensions of the midgets' two torpedo tubes. Larger Japanese submarines were armed with the 21-inch Type 95 torpedo. It was not a great success. Its first operational use was in the attack on Pearl Harbor The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii ..., after which it was modified as the Type 97 Special, sometimes known as the Type 98.

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. ...

Type 93 Torpedo
The was a -diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given to it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time. History and development The Type 93's development (in parallel with a submarine-launched model, the Type 95) began in Japan in 1928, under the auspices of Rear Admiral Kaneji Kishimoto and Captain Toshihide Asakuma. The torpedo design was inspired by the British oxygen-enriched torpedoes used on the s. At the time, the most powerful potential enemy of the Japanese Navy was the United States Navy's Pacific Fleet. The U.S. Navy's doctrine, presuming an invasion by Japan of the Philippines (an A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 95 Torpedo
The Type 95 torpedo was a torpedo used by submarines of the Imperial Japanese Navy during World War II. The Type 95 was based on the Type 93 torpedo ( ''Long Lance''); its mod 1 had a smaller and mod 2 had a larger warhead size than the Type 93's . The Type 95 was similar to the U.S. Navy's contemporary Mark 16 hydrogen peroxide torpedo, which had a shorter range, slightly higher top speed and a larger and nearly twice as powerful war head at 580 Kilograms filled with TORPEX. It was intended to be fired from a standard torpedo tube of a submerged submarine. Range of the Type 95 was (for the mod 1) at , or at , which was about three times the range of the U.S. Navy Mark 14 at the same speed when using longer range and 45 to 47 knots. The Type 95 was the fastest torpedo in common use by any navy during World War II. Its warhead size was the largest of any submarine torpedo, and second only to the Type 93 used by Japanese surface ships. Its engine was a kerosene-oxygen wet- ...

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British ...

Attack On Sydney Harbour
In late May and early June 1942, during World War II, Imperial Japanese Navy submarines made a series of attacks on the Australian cities of Sydney and Newcastle. On the night of 31 May – 1 June, three ''Ko-hyoteki''-class midget submarines, (M-14, M-21 and M-24) each with a two-member crew, entered Sydney Harbour, avoided the partially constructed Sydney Harbour anti-submarine boom net, and attempted to sink Allied warships. Two of the midget submarines were detected and attacked before they could engage any Allied vessels. The crew of M-14 scuttled their submarine, whilst M-21 was successfully attacked and sunk. The crew of M-21 killed themselves. These submarines were later recovered by the Allies. The third submarine attempted to torpedo the heavy cruiser , but instead sank the converted ferry , killing 21 sailors. This midget submarine's fate was unknown until 2006, when amateur scuba divers discovered the wreck off Sydney's northern beaches. Immediately following t ...

HMAS Kuttabul (ship)
HMAS ''Kuttabul'', formerly ''SS Kuttabul'', was a Royal Australian Navy depot ship, converted from a Sydney Ferries Limited ferry. ''Kuttabul'' and her identical sistership, '' Koompartoo'', were the largest and last K-class ferries built. ''Kuttabul'' had the highest passenger carrying capacity of any ferry on Sydney Harbour and was ordered for the crowded Milsons Point to Circular Quay route. During the Japanese midget submarine attack on Sydney Harbour on 31 May 1942, ''Kuttabul'' was sunk, with 21 naval personnel aboard. Design and construction To service the booming population growth on the North Shore prior to the construction of a bridge connection, Sydney Ferries Limited ordered the largest, and what would be the last, " K-class" ferries. They were ''Kuttabul'' and '' Koompartoo'', steam-powered ferries, built in 1922 by the Walsh Island Dockyard and Engineering Works in Newcastle. Similar in size to Manly ferries, they were rated at 448 gross and 201 net registe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torpedoes Of Japan
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though some ...

World War II Weapons Of Japan
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. '' Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
