Action Of 8 June 1945
The action of 8 June 1945, sometimes called the Sinking of ''Ashigara'' was a naval action that resulted in the sinking of the heavy cruiser of the Imperial Japanese Navy by the British Royal Navy submarine . ''Ashigara'' was transporting Japanese troops from Dutch East Indies for the defence of Singapore, and the sinking resulted in a heavy loss of life. Background ''Ashigara'' departed Batavia (present-day Jakarta) on 7 June 1945 for Singapore with 1,600 troops and 480 tons of supplies on board to reinforce the defence of that city. She was escorted by the destroyer , which had survived the Japanese defeat in the Malacca Strait. Their planned route was north from Batavia, then NNW through the Bangka Strait between Sumatra and Bangka Island, then north to Singapore. The U.S. Navy submarine USS ''Blueback'' observed their departure but was unable to maneuver into an attack position. ''Bluebacks contact report was passed on to HMS ''Trenchant'', under the command of Cdr ...

Heavy Cruiser
The heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in caliber, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armored cruisers of the years before 1905. When the armored cruiser was supplanted by the battlecruiser, an intermediate ship type between this and the light cruiser was found to be needed—one larger and more powerful than the light cruisers of a potential enemy but not as large and expensive as the battlecruiser so as to be built in sufficient numbers to protect merchant ships and serve in a number of combat theaters.

10th Area Fleet (Imperial Japanese Navy)
The was a fleet of the Imperial Japanese Navy (IJN) established during World War II as a result of IJN commands being isolated in the Philippines. History The commander in chief of the IJN 1st Southern Expeditionary Fleet based in Singapore was named commander in chief of the newly created Tenth Area Fleet on 1 February 1944. As the Southwest Area Fleet (Imperial Japanese Navy) command staff was isolated in the Philippines, a new command structure was necessary to direct the 1st and 2nd Fleets and the surviving elements of the IJN 5th Fleet. It was supported by the IJN 13th Air Fleet. The 10th Area Fleet had responsibility for the defenses of Indonesia and Indochina. It lost most of its combat capability at the Battle of the Malacca Strait The Battle of the Malacca Strait, sometimes called the Sinking of ''Haguro'', and in Japanese sources as the Battle off Penang (ペナン沖海戦), was a naval battle that resulted from the British search-and-destroy operation in May 1 ...

Subic Bay
Subic Bay is a bay on the west coast of the island of Luzon in the Philippines, about northwest of Manila Bay. An extension of the South China Sea, its shores were formerly the site of a major United States Navy facility, U.S. Naval Base Subic Bay, now an industrial and commercial area known as the Subic Bay Freeport Zone under the Subic Bay Metropolitan Authority. Today, water as well as the towns and establishments surrounding the bay are collectively known as Subic Bay. This includes the former naval base, Hanjin shipyard, Olongapo city, the municipal town of Subic, and the erstwhile US defense housing areas of Binictican and Kalayan housing, up to Morong, Bataan. The bay was long recognized for its deep and protected waters, but development was slow due to lack of level terrain around the bay. History In 1542, Spanish conquistador Juan de Salcedo sailed into Subic Bay but no port developed there because the main Spanish naval base would be established in the nearby Ma ...

Port And Starboard
Port and starboard are nautical terms for watercraft and aircraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side, it is usually only on the port side (hence the name). Side Port and starboard unambiguously refer to the left and right side of the vessel, not the observer. That is, the port side of the vessel always refers to the same portion of the vessel's structure, and does not depend on which way the observer is facing. The port side is the side of the vessel which is to the left of an observer aboard the vessel and , that is, facing forward towards the direction the vehicle is heading when underway, and starboard side is to the right of such an observer. This convention allows orders and information to be given unambiguously, withou ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

Shell (projectile)
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles that is properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape ...

HNLMS O 19
''O 19'', laid down as ''K XIX'', was an of the Royal Netherlands Navy that saw service during World War II. ''O 19'', along with her sister ship , were the first submarines in the world to be equipped with a submarine snorkel that allowed the submarine to run its diesel engines while submerged. Ship history Commissioning The submarine's keel was laid at the Wilton-Fijenoord shipyard in Rotterdam on 15 June 1936 as ''K XIX'' but was renamed ''O 19'' at some point. The submarine was launched on 22 September 1938 and commissioned in the Dutch navy on 3 July 1939. After her commissioning the HNLMS ''O 19'' was put into service by commander Lieutenant-on-sea 1 (LTZ 1) K. van Dongen on July 3, 1939, following a short training period. Three weeks later, on 25 July 1939, the new submarine was already on its way to the Dutch East Indies via the Suez Canal where the boat arrived on 13 September. World War II On 10 May 1940, the day the Germans invaded the Netherlands, the entire mobili ...

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 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. Secondary na ...

Shoal
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refer ...
