Kaibōkan
or coastal defense ship was a type of naval ship used by the Imperial Japanese Navy during World War II for escort duty and coastal defense. The term escort ship was used by the United States Navy to describe this category of Japanese ships.REPORTS OF THE U. S.

Type D Escort Ship
The were a class of escort ships in the service of the Imperial Japanese Navy during World War II. The Japanese called them "Type D" coast defence ships, and they were the sixth class of ''Kaibōkan'' (''Kai'' = sea, ocean, ''Bo'' = defence, ''Kan'' = ship), a name used to denote a multi-purpose vessel. 143 ships were ordered under the 1943-44 Programme, and a further 57 units were planned (but never ordered) under the 1944-45 Programme, for an overal total of 200 ships. However only 67 were completed, with the remainder being cancelled. Background The Type D, like the and es, were dedicated to the anti-aircraft (AA) and anti-submarine role. On 22 April 1943, the Navy General Staff decided a mass production of escort ships, because of the urgent need to protect the convoys which were under constant attack. The plan was to build a basic escort ship of around 800 tons, with a simple design for easy construction. The first designs, for "Type A" and "Type B" ''Mikura'' class, s ...

List Of Escort Vessel Classes Of World War II
During World War II, the navies of both the Allies and the Axis Powers built and operated hundreds of relatively small warships for the purpose of ensuring the safety of merchant convoys. These warships displaced around 1,000 tons and were typically armed with one-to-three guns of three-to-five inches in caliber, numerous smaller anti-aircraft guns and depth charge throwers. Summary Allied escort vessel classes United States (destroyer escorts and frigates and patrol craft) * ''Evarts''-class destroyer escort - 97 built * ''Buckley''-class destroyer escort - 148 built * ''Cannon''-class destroyer escort - 72 built * ''Edsall''-class destroyer escort - 85 built * ''Rudderow''-class destroyer escort - 22 built * ''John C.

Chinese Cruiser Ping Hai
''Ping Hai'' () was a light cruiser in the Chinese fleet before World War II and the second ship of the . The ship was laid down in China to the specifications supplied by the Japanese, and Japanese advisors were hired to oversee the construction. Compared to its sister ship ''Ning Hai'', it had a lower-output powerplant and lacked seaplane facilities. Its anti-aircraft armament was also different from that of its sister. The progress of its construction was affected by the Mukden Incident (18 September 1931) and the January 28 Incident (28 January – 3 March 1932). Disruption of parts supply and non-cooperation of Japanese advisors delayed its launch date from the originally planned 10 October 1933 to 28 September 1935. Blocked delivery of originally-specified anti-aircraft weapons meant that equivalent replacements of those weapons had to be bought via Germany. When it was completed in 1936, official outbreak of war was barely a year away. Service record ''Ping Hai'' serv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Cruiser Ning Hai
''Ning Hai'' () was a light cruiser in the Republic of China Navy (ROCN) before World War II and the lead ship of her class. She was sunk in the early days of the Second Sino-Japanese War by aircraft from the Imperial Japanese Navy, and her wreck was raised and repaired by the Japanese, re-entering service with the Japanese Navy in the Pacific War as the escort vessel . She was sunk again in September 1944 by a USN submarine. page 113 Background By the end of the 1920s, the ROCN had only four antiquated 19th century protected cruisers and two training cruisers received before World War I. The Kuomintang government had an ambitious re-armament plan but lacked funds, and after extensive negotiations with shipbuilders in the United States, United Kingdom, Germany and Japan, placed an order with the Japanese for one light cruiser to be built in Japan, with a second vessel to be built in China with Japanese assistance. Despite the very strained political relations between Japan and C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer Escort
Destroyer escort (DE) was the United States Navy mid-20th-century classification for a warship designed with the endurance necessary to escort mid-ocean convoys of merchant marine ships. Development of the destroyer escort was promoted by the British need in World War II for anti-submarine ships that could operate in open oceans at speeds of up to 20 knots. These "British Destroyer Escort"s were designed by the US for mass-production under Lend Lease as a less expensive alternative to fleet destroyers. The Royal Navy and Commonwealth forces identified such warships as frigates, and that classification was widely accepted when the United States redesignated destroyer escorts as frigates (FF) in 1975. From circa 1954 until 1975 new-build US Navy ships designated as destroyer escorts (DE) were called ocean escorts. Similar types of warships in other navies of the time included the 46 diesel-engined ''Kaibōkan'' of the Imperial Japanese Navy, 10 ''Kriegsmarine'' F-class escort ...

The plan was to build a basic escort ship of around 800 tons, with a simple design for easy construction. The first designs, for "Type A" and "Type B" , still needed too many man-hours for building, so in June 1943, the Navy General Staff planned for a simplified design.

Kriegsmarine
The (, ) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic. The was one of three official branches, along with the and the , of the , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines (U-boat ...

Convoy Hi-81
was the designation for a formation of Japanese transports that carried soldiers bound for Singapore and the Philippines during World War II. The transports were escorted by a large force of surface combatants including the escort carriers ''Shinyo'' and ''Akitsu Maru'' which were sunk in the Yellow Sea by American submarines. Over the course of a four-day convoy battle in November 1944 nearly 7,000 Japanese were killed in action while the Americans sustained no casualties. Background Convoy Hi-81 was under the command of Rear Admiral Tsutomu Sato of the Eighth Escort Fleet in the escort ship ''Etorofu''. ''Shinyo'' was commanded by Captain Shizue Ishii and the ''Akitsu Maru'' was actually serving as an aircraft ferry in the convoy. The other Japanese vessels known to have taken part in the mission was the seaplane tender ''Kiyokawa Maru'', the destroyer ''Kashi'', the escort ships ''Tsushima'', ''Daito'', ''Kume'', ''Shonan'', ''CD No. 9'' and ''CD No. 61''.

Modular Design
Modular design, or modularity in design, is a design principle that subdivides a system into smaller parts called ''modules'' (such as modular process skids), which can be independently created, modified, replaced, or exchanged with other modules or between different systems. Overview A modular design can be characterized by functional partitioning into discrete scalable and reusable modules, rigorous use of well-defined modular interfaces, and making use of industry standards for interfaces. In this context modularity is at the component level, and has a single dimension, component slottability. A modular system with this limited modularity is generally known as a platform system that uses modular components. Examples are car platforms or the USB port in computer engineering platforms. In design theory this is distinct from a modular system which has higher dimensional modularity and degrees of freedom. A modular system design has no distinct lifetime and exhibits flexibility ...

Japanese Battleship Mikasa
is a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s. Named after Mount Mikasa in Nara, Japan, the ship served as the flagship of Vice Admiral Tōgō Heihachirō throughout the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war and the Battles of the Yellow Sea and Tsushima. Days after the end of the war, ''Mikasa''s magazine accidentally exploded and sank the ship. She was salvaged and her repairs took over two years to complete. Afterwards, the ship served as a coast-defence ship during World War I and supported Japanese forces during the Siberian Intervention in the Russian Civil War. After 1922, ''Mikasa'' was decommissioned in accordance with the Washington Naval Treaty and preserved as a museum ship at Yokosuka. She was badly neglected during the post-World War II Occupation of Japan and required extensive refurbishing in the late 1950s. She has been partially restored, and is n ...

Romanian Navy
The Romanian Navy ( ro, Forțele Navale Române) is the navy branch of the Romanian Armed Forces; it operates in the Black Sea and on the Danube. It traces its history back to 1860. History The Romanian Navy was founded in 1860 as a river flotilla on the Danube. After the unification of Wallachia and Moldavia, Alexandru Ioan Cuza, the ruling Domnitor of the Romanian Principalities, decided on 22 October 1860 by order no. 173 to unify the navies into a single flotilla. The navy was French-trained and organized.Axworthy, p. 327 Officers were initially sent to Brest Naval Training Centre in France, as the Military School in Bucharest did not have a naval section. The first Commander-in-chief of the navy was Colonel Nicolae Steriade. The base was first established in 1861 at Izmail, but it was later relocated in 1864 to Brăila and in 1867 to Galați. The equipment was modest at best, with 3 ships from Wallachia and 3 from Moldavia, manned by 275 sailors. The main goal of the navy ...
