South Korea gets most advanced submarine

South Korea has received its most advanced submarine to counter North Korea's underwater combat capabilities, the country's defense procurement agency says.

The delivery of the 1,800-tonne Yu Gwan-sun submarine at Daewoo Shipbuilding and Marine Engineering shipyard on Geoje Island near Busan in southeastern part of the country was marked with a ceremony by the South Korean navy, the Defense Acquisition Program Administration (DAPA) said in a statement.

The submarine, which the South Korean navy plans to deploy in December, is named after well-known independence leader Yu Gwan-sun, and is the sixth and most sophisticated in the Jang Bogo-II class that was launched in 2008.

The new submarine is expected to improve South Korea's underwater prowess against North, which is believed to have a fleet of at least 80 submarines.

North and South Korea are technically still at war, since the Korean war (1950-1953) ended with a ceasefire that was never replaced with a peace treaty.
