South Korea's HD Hyundai Heavy Industries launched a new Republic of Korea Navy (ROKN) guided-missile destroyer on Wednesday, September 17.
The future ROKS Dasan Jeong Yak-yong is the second unit of three ships under batch II of the ROKN's KDX-III or Sejong the Great-class destroyers. This makes her the fifth vessel overall in the Sejong the Great-class.
As with her KDX-III batch II sisters, the future Dasan Jeong Yak-yong will have a length of 170 metres, a beam of 21 metres, a displacement of 8,200 tonnes, a maximum speed of 30 knots, and armament consisting of a 127mm naval gun, surface-to-air missiles, anti-ship missiles, land attack cruise missiles, and torpedoes. Installation of the Aegis Combat System will enable the ship to successfully intercept ballistic missiles.
The destroyer will also have aviation facilities for use by an MH-60R Seahawk helicopter. The electronics suite will meanwhile include a phased array radar and an integrated sonar system.
Dasan Jeong Yak-yong's batch II sister, ROKS Jeongjo the Great, was commissioned into service late last year.
