Development

The Blue Shark torpedo can be deployed from surface ships, ASW helicopters and maritime patrol aircraft. Production cost for each torpedo is at about ₩ 1,000,000,000.[2]

Blue Shark torpedoes are fitted to the Incheon class frigate (FFX).[3] It is exported to the Philippines as part of the acquisition process for the Jose Rizal-class Frigates.[4]

Variants

An improved variant, the lightweight torpedo-2 is being developed by LIG Nex1. New capabilities include longer range and lesser vulnerability to decoys.[5] The research and development program is expected to be complete in 2029.[6]
