2018 Japan–South Korea Radar Lock-on Dispute
The 2018 Japan–South Korea radar lock-on dispute is about an incident between a Japanese aircraft and a South Korean vessel. The aircraft was part of the Japan Maritime Self-Defense Force (JMSDF), while the vessel was part of the Republic of Korea Navy (ROKN). The event occurred on 20 December 2018, without the firing of any weapon, and was followed by a large diplomatic dispute between Japan and South Korea. Incident According to the government of Japan, a South Korean naval destroyer, ROKS ''Gwanggaeto the Great'', directed its STIR-180 fire-control radar at a maritime patrol aircraft, Kawasaki P-1 belonging to the Fleet Air Wing 4 of JMSDF, which was conducting surveillance off the Noto Peninsula in the Sea of Japan on Thursday 20 December 2018 at around 3:00 p.m. (JST). According to Japan Ministry of Defense (MOD), aiming the fire-control (FC) radar at a plane is violation of the Code for Unplanned Encounters at Sea (CUES), as a lock with the FC radar is gene ...

Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to political issues, but it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Korean Ghost Ships
Every year, dozens of derelict boats from North Korea wash up on Japanese shores; some of the boats house the remains of their crew. These "ghost ships" are believed to result when North Korean fishermen, often having to travel further out to sea to catch fish due to China's notorious overfishing in N. Korean waters, are lost at sea and succumb to exposure or starvation. Analysis Fishing is a dangerous occupation worldwide; for example, the work-related fatality rate for Australian fisherman in one study was 143 per 100,000 man-years, which was 18 times the Australian national average work-related fatality rate. During the winter, North Korean fishing boats go out searching for king crab, squid and sandfish. Some of the boats appear to be either operated by soldiers or rented by the army to civilians. Fish is one of the main exports from North Korea to China. Wreckage from North Korean boats often washes ashore in northern Japan during winter due to seasonal winds. The ghost s ...

Distress Signal
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by a serious or imminent danger and requires immediate assistance.Aeronautical Information Manual U.S. Federal Aviation Administration, 2016 Use of distress signals in other circumstances may be against local or .

Fishing Vessel
A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing. The total number of fishing vessels in the world in 2016 was estimated to be about 4.6 million, unchanged from 2014. The fleet in Asia was the largest, consisting of 3.5 million vessels, accounting for 75 percent of the global fleet. In Africa and North America the estimated number of vessels declined from 2014 by just over 30,000 and by nearly 5,000, respectively. For Asia, Latin America and the Caribbean and Oceania the numbers all increased, largely as a result of improvements in estimation procedures.FAO 2007 It is difficult to estimate the number of recreational fishing boats. They range in size from small dinghies to large charter cruisers, and unlike commercial fishing vessels, are often not dedicated just to fishing. Prior to the 1950s there was little standardisation of fishing boats. Desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korea Coast Guard Vessel 5001 Sambongho
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the " Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JMSDF P-1 (9)
, abbreviated , also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel. History Origin Following Japan's defeat in World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance. Ships were disarmed, and some of them, such as the battleship , were taken by the Allied Powers as reparation. The remaining ships were used for repatriation of the Japanese soldiers from abroad and also for minesweeping in the area around Japan, initially under the control of the ''Second Bureau of the Demobilization Ministry''. The minesweeping fleet was eventually transferred to the newly formed Maritime Safety Agency, which helped maintain the resources and expertise of the navy. Japan's 1947 Constitut ...

Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...

Target Acquisition
Target acquisition is the detection and identification of the location of a target in sufficient detail to permit the effective employment of lethal and non-lethal means. The term is used for a broad area of applications. A "target" here is an entity or object considered for possible engagement or other action (see Targeting). Targets include a wide array of resources that an enemy commander can use to conduct operations including mobile and stationary units, forces, equipment, capabilities, facilities, persons and functions. It may comprise target acquisition, Joint Targeting or Information Operations. Technically target acquisition may just denote the process of a weapon system to decide which object to lock on to, as opposed to surveillance on one and target tracking on the other side; for example in an anti-aircraft system. History Target acquisition under the doctrines of the Cold War and post–Cold War were focused on identifying the capabilities, assets and identiti ...
