K731 White Shark (Korean: 백상어; RR: Baek-sang-eo) heavy torpedo is a submarine-launched torpedo developed by the Republic of Korea Navy in 2004. Production was delayed for a year after a program error in the guidance system resulted in 2 failed tests in 2003. This glitch was fixed while developing the lighter-weight Blue Shark torpedo. Production cost for each torpedo is at about 950 million won (US$790,000).
