Donghae-class Corvette
The ''Donghae''-class PCC (Patrol Combat Corvette) (Hangul: 동해급 초계함, Hanja: 東海級哨戒艦) is the low-end complement of the high-low mix domestic naval construction plan of the Republic of Korea Navy under the 1st Yulgok Project (1974-1986) for the Republic of Korea Armed Forces. The ship is designed for patrolling maritime border, including the Northern Limit Line, protecting the littoral zone, and combating the North Korean vessels. Since 1983, a total of 4 ''Donghae''-class corvettes commissioned in the Republic of Korea Navy. The decommission of the class started in 2009, and is being replaced with series of FFX program. As of 2021, only 1 remains in service with the Colombian Navy. Development Prior to the ''Donghae''-class, the Republic of Korea Navy operated ex-US warships of similar role and size built during the World War II, which the ships were in imminent retirement condition in 1980. Meanwhile, the lead ship of ''Ulsan''-class frigate was under con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 tons and 2,000 .although recent designs may approach 3,000 tons, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance and seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank "corvette captain", equivalent in many navies to "lieutenant commander", derives from the name of this type of ship. The rank is the most junior of three "captain" ranks in sev ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asheville-class Gunboat
The ''Asheville''-class gunboats were a class of small warships built for the United States Navy in response to the Cuban Missile Crisis. The class is named for a city in western North Carolina and the seat of Buncombe County. All ''Asheville''-class gunboats have since been donated to museums, scheduled for scrapping, or transferred to the Greek, Turkish, Colombian and South Korean Navies. The last two Asheville-class gunboats in US service were and , which were operated by the Naval Surface Warfare Center until they were stricken in 2016. Origination The ''Asheville''-class gunboats were originally designated PGM motor gunboats, but were reclassified in 1967 as PG patrol combatant ships. The ''Asheville'' class employed a combined diesel or gas turbine (CODOG) propulsion system; twin Cummins diesel engines for endurance, and a GE LM1500 gas turbine for high-speed dash. Engine controls were operated by pneumatics. The controllable reversible pitch propeller a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auk-class Minesweeper
The ''Auk'' class were a class of minesweepers serving with the United States Navy and the Royal Navy during the Second World War. In total, there were 93 ''Auk''s built. Design and development Prior to the United States entering World War II, they had produced two ships of the for testing and evaluation. From these two examples it was decided that the use of Diesel-electric engines to power the ship and the minesweeping equipment, rather than separate geared diesel engines to propel the ship and diesel generators to energize the minesweeping equipment, would work better. The Royal Navy placed an order for 32 of these minesweepers from the United States, ''BAM-1''-''BAM-32''. Because of the additional equipment, the displacement was raised from on the ''Raven''s, to on what would come to be known as the ''Auk'' -class in the USN, and the ''Catherine''-class in the RN. The ''Auk'' class displaced 890 long tons, with a length of , a beam of , and a draft of . They had a maximu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PCE-842-class Patrol Craft
The ''PCE-842''-class patrol craft were United States Navy patrol craft escorts designed during World War II that were intended for coastal and convoy escort. The design was derived from the as a substitute for the s that were used for anti-submarine warfare (ASW) in coastal areas. At 185 feet long and 640 tons, the PCE is more than twice the displacement of the PC and thus and in combination with a less powerful engine also much slower. It has a crew complement of 99 officers and men. Development and design The ''Admirable'' class had been developed as a smaller minesweeper than the and s, which would be cheaper and easier to build, while still having good seakeeping capabilities in high seas. An escort derivative of the new design was proposed for supply under the Lend-Lease scheme to Britain's Royal Navy (which had already rejected the ''Admirable'' class as minesweepers), and when the United States Navy realized that a shortage of engines might prevent it from receiving add ...

Ulsan-class Frigate
The ''Ulsan''-class frigate (Hangul: 울산급 호위함, Hanja: 蔚山級護衛艦) is the high-end complement of the high-low mix domestic naval construction plan of the Republic of Korea Navy under the 1st Yulgok Project (1974–1986) for the Republic of Korea Armed Forces. Design The ''Ulsan'' class is a light frigate built by Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering. The frigates are in length with a top speed of and range of at . Ships in class Foreign variant Bangladesh Navy In June 2001, the Bangladesh Navy commissioned a frigate based on the ''Ulsan''-class frigate but the design was heavily modified.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Limit Line
The Northern Limit Line or North Limit Line (NLL) – 북방한계선 (in ROK) – is a disputed maritime demarcation line in the Yellow (West) Sea between the Democratic People's Republic of Korea (DPRK) on the north, and the Republic of Korea (ROK) on the south. This line of military control acts as the ''de facto'' maritime boundary between North and South Korea.Elferink, Alex G. Oude. (1994). Description The line runs between the mainland portion of Gyeonggi-do province that had been part of Hwanghae before 1945, and the adjacent offshore islands, including Yeonpyeong and Baengnyeongdo. Because of the conditions of the armistice, the mainland portion reverted to North Korean control, while the islands remained a part of South Korea despite their close proximity. The line extends into the sea from the Military Demarcation Line (MDL), and consists of straight line segments between 12 approximate channel midpoints, extended in an arc to prevent egress between both sides ...

Hanja
Hanja (Hangul: ; Hanja: , ), alternatively known as Hancha, are Chinese characters () used in the writing of Korean. Hanja was used as early as the Gojoseon period, the first ever Korean kingdom. (, ) refers to Sino-Korean vocabulary, which can be written with Hanja, and (, ) refers to Classical Chinese writing, although "Hanja" is also sometimes used to encompass both concepts. Because Hanja never underwent any major reforms, they are mostly resemble to ''kyūjitai'' and traditional Chinese characters, although the stroke orders for some characters are slightly different. For example, the characters and as well as and . Only a small number of Hanja characters were modified or are unique to Korean, with the rest being identical to the traditional Chinese characters. By contrast, many of the Chinese characters currently in use in mainland China, Malaysia and Singapore have been simplified, and contain fewer strokes than the corresponding Hanja characters.
