Korea has developed a long-range anti-submarine missile which can hit an enemy submarine about 20 km away. The "Red Shark" has a longer range and far sharper accuracy than the light torpedoes normally fired by conventional vessels or aircraft. The Defense Acquisition Program Agency developed the Red Shark at a cost of about W100 billion (US$1=W1, 276) over nine years. Europe, Russia and the U.S. have anti-submarine missiles, but the Red Shark is only the second vertical-launch anti-submarine rocket developed in the world following the U.S.

Red Sharks are 5.7 m long and 0.38 m in diameter, weigh 820 kg, and cost about W2 billion. They will be installed in the Korean-made vertical launch system of the 5,000 t-class KDX-II and KDX-III Aegis destroyers.
