A-class Minesweeper
The ''A'' class were four minesweepers of the Royal Netherlands Navy. They were the first purpose-built minesweepers of the Dutch Navy, as earlier minesweepers were converted tugboats. Design The ''A'' class was based on a German design used during the First World War. History All ships of the ''A'' class were built between 1928 and 1930 at Willemsoord, Den Helder. All four ships were commissioned on 4 August 1930, and two days later, on 6 August 1930, all four sailed to the Dutch East Indies, arriving at Surabaya on 30 October 1930. During the Japanese invasion of the Dutch East Indies in March 1942 all four ships were scuttled by their crews. Three of the ships, ''A'', ''B'' and ''C'', were salvaged and put into service with the Imperial Japanese Navy as auxiliary submarine chasers no. 113, 112 and 116, being rearmed with a single 47 mm gun, three 25 mm cannons, a 13.2 mm machine gun and eight depth charges. All three were sunk by US forces in 1944 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

QF 3-pounder Hotchkiss
The QF 3-pounder Hotchkiss or in French use Canon Hotchkiss à tir rapide de 47 mm were a family of long-lived light naval guns introduced in 1886 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 32 to 50 calibers but 40 caliber was the most common version. They were widely used by the navies of a number of nations and often used by both sides in a conflict. They were also used ashore as coastal defense guns and later as an anti-aircraft gun, whether on improvised or specialized HA/LA mounts. Operational history French service The French Navy used two versions of the Hotchkiss 3-pounder: the short-barreled M1885 and the long-barreled M1902, which had a larger muzzle velocity than its predecessor. The French L/40 M1885 and the British QF 3-pounder were largely the same gun. Like the British who paired their 3-pounders with the larger QF 6-po ...

Hotchkiss M1929 Machine Gun
The 13.2 mm Hotchkiss machine gun model 1929, often simplified to Hotchkiss M1929 machine gun, and the like, was a heavy machine gun designed and manufactured by Hotchkiss et Cie from the late 1920s until World War II which saw service with various nations' forces, including Italy and Japan where the gun was built under license. Development In the late 1920s, Hotchkiss proposed a range of anti-aircraft automatic weapons in the 13.2, 25 and 37 mm calibers. They were all based on the same type of gas-operated action, similar to the one used in the 8 mm Hotchkiss Mle 1914 machine gun, which had proven extremely reliable during World War I and was still in service. This led to the production of the 13.2 mm Hotchkiss machine gun model 1929, often called the Hotchkiss M1929. Performance The Hotchkiss M1929 machine gun had a cyclic rate of fire of 450 rounds per minute, but their practical sustained rate of fire was just 200-250 rounds per minute due to limited m ...

Submarine Chaser
A submarine chaser or subchaser is a small naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II. Submarine chaser variants U.S. Navy submarine chasers were designed specifically to destroy German submarines in World War I, and Japanese and German submarines in World War II. The small SC-1-class submarine chasers of the design used in World War I carried the hull designator SC (for Submarine Chaser). Their main weapon was the depth charge. They also carried machine guns and anti-aircraft guns. The similar-sized SC-497-class was built for World War II. Also in World War II, larger PC-461-class submarine chasers used the PC hull classification symbol (for Patrol, Coastal).Gardiner and Chesneau, pp. 71, 152-154 Class relationships: * 438 (98t, wooden hull) * 343 (450t, steel hull) * 68 (850t, steel hull) ** used in sim ...

Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch Empire, Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. ...

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.

Dutch East Indies Campaign
The Dutch East Indies campaign of 1941–1942 was the conquest of the Dutch East Indies (present-day Indonesia) by forces from the Empire of Japan in the early days of the Pacific campaign of World War II. Forces from the Allies attempted unsuccessfully to defend the islands. The East Indies were targeted by the Japanese for their rich oil resources which would become a vital asset during the war. The campaign and subsequent three and a half year Japanese occupation was also a major factor in the end of Dutch colonial rule in the region. Background The East Indies was one of Japan's primary targets if and when it went to war because the colony possessed abundant valuable resources, the most important of which were its rubber plantations and oil fields; the colony was the fourth-largest exporter of oil in the world, behind the U.S., Iran, and Romania. The oil made the islands enormously important to the Japanese, so they sought to secure the supply for themselves. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
