Sang-O-class Submarine
The ''Sang-O'' (''Shark'') class of submarines (Hangul: 상어급 잠수함) are diesel-electric coastal submarines in service with the Korean People's Navy, the navy of North Korea. They are the country's second largest indigenously-built submarines. Though North Korean military capabilities are mostly kept classified, it was reported that North Korea maintains 40 ''Sang-O''-class submarines as of February 2021. History The ''Sang-O''-class was introduced in 1991, produced at Bong Dao Bo Shipyards in Sinpo. A single unit was captured by the Republic of Korea Navy (South Korea) after it ran aground on 18 September 1996 in the Gangneung submarine infiltration incident. The siezed ''Sang-O''-class submarine was placed on display at Unification Park near Gangneung Gangneung () is a municipal city in the province of Gangwon-do, on the east coast of South Korea.

Yugo-class Submarine
The Yugo class submarine is a class of four midget submarines used primarily for infiltration and espionage by North Korea. The Yugo class was given its name because it was built to plans supplied to North Korea by Yugoslavia in 1965. Design The Yugo class is a family of midget submarines that are not all identical. The displacement is either the standard 90 tons of the original Yugoslavian design for the early units or 110 tons for the later units. Armament is either a pair of 400 mm torpedo tubes (early units) or a pair of 21 in (533mm) short torpedo tubes (later units). All units have the same range: at on the surface and at submerged. History The final vessel was built in the 1980s, after which they were superseded by the Sang-O-class submarines. On June 12, 1998, one out of six submarines was captured by the South Koreans. In the early 2000s, Vietnam "gained experience" with these craft prior to ordering Russian Kilo-class diesel-electric submarines for deni ...

Hangul
The Korean alphabet, known as Hangul, . Hangul may also be written as following South Korea's standard Romanization. ( ) in South Korea and Chosŏn'gŭl in North Korea, is the modern official writing system for the Korean language. The letters for the five basic consonants reflect the shape of the speech organs used to pronounce them, and they are systematically modified to indicate phonetic features; similarly, the vowel letters are systematically modified for related sounds, making Hangul a featural writing system. It has been described as a syllabic alphabet as it combines the features of alphabetic and syllabic writing systems, although it is not necessarily an abugida. Hangul was created in 1443 CE by King Sejong the Great in an attempt to increase literacy by serving as a complement (or alternative) to the logographic Sino-Korean ''Hanja'', which had been used by Koreans as its primary script to write the Korean language since as early as the Gojoseon period (spanni ...

1996 Gangneung Submarine Infiltration Incident
The 1996 Gangneung submarine infiltration incident occurred on 18 September 1996, near the South Korean town of Gangneung. The incident was one of the more serious instances of North Korean espionage involving the Reconnaissance General Bureau, Reconnaissance Bureau (reconnaissance team and 22nd Squadron of the Maritime Department of the Reconnaissance Bureau). The raid was launched by North Korean armed spies to assassinate the President of South Korea, Kim Young-sam, during his visit to Chuncheon, on 5 October 1996. History Landing On 15 September 1996, a North Korean landed a three-person special operations reconnaissance team on the east coast of South Korea near Jeongdongjin, south-east of Gangneung, Gangwon-do (South Korea), Gangwon-do. Their mission was to spy on the naval installations in the area and then return. However, the larger mission was the assassination of South Korean President Kim Young-sam.

Sinpo
SINPO, an acronym for Signal, Interference, Noise, Propagation, and Overall, is a Signal Reporting Code used to describe the quality of broadcast and radiotelegraph transmissions. SINPFEMO, an acronym for Signal, Interference, Noise, Propagation, frequency of Fading, dEpth, Modulation, and Overall is used to describe the quality of radiotelephony transmissions. SINPFEMO code consists of the SINPO code plus the addition of three letters to describe additional features of radiotelephony transmissions. These codes are defined by ''Recommendation ITU-R Sm.1135, SINPO and SINPFEMO codes''. SINPO code is most frequently used in reception reports written by shortwave listeners. Each letter of the code stands for a specific factor of the signal, and each item is graded on a 1 to 5 scale (where 1 stands for nearly undetectable/severe/unusable and 5 for excellent/nil/extremely strong). The code originated with the CCIR (a predecessor to the ITU-R) in 1951, and was widely used by BBC s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Korean People's Navy
The Korean People's Army Naval Force (KPANF; Korean: 조선인민군 해군; Hanja: 朝鮮人民軍 海軍; ''Chosŏn-inmingun Haegun''; ) or the Korean People's Navy (KPN), is the naval service branch of the Korean People's Army, which contains each branch of the North Korean armed forces. There are some 780 vessels including 70 midget submarines (including the Yono-class submarine and Sang-O-class submarine), 20 Romeo-class submarines, and about 140 air cushioned landing craft. The North Korean navy is considered a brown-water (or riverine) navy and operates mainly within the 50 kilometer exclusion zone. The fleet consists of east and west coast squadrons, which cannot support each other in the event of war with South Korea. The limited range of its vessels means that, even in peacetime, it is virtually impossible for a ship on one coast to visit the other coast. History The KPN was established on 5 June 1946.

Diesel-electric Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of spe ...

Submarine Snorkel
A submarine snorkel is a device which allows a submarine to operate submerged while still taking in air from above the surface. British Royal Navy personnel often refer to it as the snort. A concept devised by Dutch engineers, it was widely used on German U-boats during the last year of World War II and known to them as a ''Schnorchel''. History Until the advent of nuclear power, submarines were designed to operate on the surface most of the time and submerge only for evasion or for daylight attacks. Until the widespread use of radar after 1940, at night a submarine was safer on the surface than submerged, because sonar could detect boats underwater but was almost useless against a surface vessel. However, with continued radar improvement as the war progressed, submarines (notably, the German U-boats in the Battle of the Atlantic) were forced to spend more time underwater, running on electric motors that gave speeds of only a few knots and very limited range.

Sinpo-class Submarine
The Sinpo class submarine, also called the ''Gorae'' ("whale") GlobalSecurity.org, accessed 2017-04-18 or ''Pongdae'' class, is a new class of submarine produced in North Korea. Only one submarine has been observed in service. It is the largest submarine designed and built for the Korean People's Navy. Design and features The design may be influenced by older Yugoslavian designs such as Heroj-class submarine, Heroj and Sava-class submarine, Sava. There has been speculation the design is influenced by modern Russian submarines of Kilo-class submarine, Kilo class, or Golf-class submarine, Golf class submarine, but the submarine is significantly smaller than these designs. If the design is successful, the Sinpo class could replace ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
