Hong Sang Eo

Hong Sang Eo (Red Shark) torpedo (Hangul: 홍상어 어뢰), also called the K-ASROC, is a vertically launched anti-submarine missile successively developed and tested by South Korea's University of Science and Technology, the Korea Agency for Defense Development (ADD) and the Republic of Korea Navy in 2009. The Red Shark missile has a range of 12 mi and carries a K745 Blue Shark torpedo that is deployed by parachute near the intended target. After release, the Blue Shark independently searches for the target.

The missiles are planned to be deployed on KDX-II and KDX-III destroyers starting in 2010. Each destroyers will carry between 8 (KDX-II) to 16 (KDX-III) of the missiles. The development cost of the program was around US$ 80 million, with production cost of about $14 million. They were designed in order to combat the potential threat of North Korean submarines.
