Notes

ROKS Cheonan (PCC-772) was a Pohang-class corvette of the Republic of Korea Navy (ROKN), commissioned in 1989. On 26 March 2010, she broke in two and sank near the sea border with North Korea, killing 46 sailors. An investigation conducted by an international team of experts from South Korea, United States, United Kingdom, Canada, Australia, and Sweden concluded that Cheonan was sunk by a torpedo launched by a North Korean Yeono-class miniature submarine.^[2]^[3]^[8]^[9]^[10]
