A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a fish. The term torpedo originally applied to a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate a self-propelled underwater explosive device.

With a career total of 44,701 GRT sunk or damaged, she is the highest-scoring Soviet submarine in history.
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures.
A midget submarine is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff.

The class is exclusively designed for export market. Despite not being operated by the German Navy, five variants of the class have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008.

The Republic of Korea Navy was founded on November 11, 1945 as Marine Defense Group after Korea was liberated from the Empire of Japan. The ROK Navy is the oldest service within the ROK Armed Forces. In 2015, the South Korean navy celebrated its 70th anniversary.
The Pohang-class PCC 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. It was originally planned as a Batch II production of Donghae-class corvette, but many changes on overall design, notably applying the hull design of Ulsan-class frigate, reclassified the ship to its own class. The ship is designed for patrolling maritime border, including the Northern Limit Line, protecting the littoral zone, and combating the North Korean vessels.
Events in the year 2010 in South Korea.
The ROKS Cheonan sinking occurred on 26 March 2010, when Cheonan, a Pohang-class corvette of the Republic of Korea Navy, carrying 104 personnel, sank off the country's west coast near Baengnyeong Island in the Yellow Sea, killing 46 seamen. The cause of the sinking remains in dispute, although evidence points to North Korea.
ROKS Cheonan (PCC-772) was a Pohang-class corvette of the Republic of Korea Navy (ROKN), commissioned in 1989. On 26 March 2010, she broke in two and sank near the sea border with North Korea, killing 46 sailors. An investigation conducted by an international team of experts from South Korea, United States, United Kingdom, Canada, Australia, and Sweden concluded that Cheonan was sunk by a torpedo launched by a North Korean Yeono-class miniature submarine.
When the South Korea-led international investigation's report on the sinking was released on 20 May 2010 there was international condemnation of the North's actions. China was an exception as they simply termed the incident "unfortunate" and "urged stability on the peninsula." This was speculated to be China's concern for instability on the Korean peninsula. Christian Oliver stated in The Financial Times that South Korea needs to explain why its navy started shooting northwards immediately, thus risking starting a war, and give reassurance on the competence of predominantly conscript forces.

The Jang Bogo-class submarine is a variant of the Type 209 diesel-electric attack submarine initially developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, intended for service with the South Korean Navy and Indonesian Navy. A Daewoo (DSME)-upgraded model of the Jang Bogo class Type 209 was exported by Korea to Indonesia in 2012, amid heavy competition from Russian, French, and German-Turkish consortiums including from Germany's original Type 209. The variant was considered for possible purchase by Thailand as well, as both newly built and second-hand options. The class is named for ancient Korean maritime figure Jang Bogo.
The Daegu-class frigate is a class of guided missile frigates of the Republic of Korea Navy (ROKN). The Daegu class is based on the preceding Incheon class, and has otherwise been referred to as the Incheon class batch II, or FFG-II.

The Daegu-class frigates are to be built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.
