ROKS Cheonan (FFG-826) is the seventh ship of the Daegu-class frigate in the Republic of Korea Navy. She is named after the city, Cheonan.
The Daegu class is an improved variant of the Incheon-class frigate. Modifications to the Incheon class include a TB-250K towed array sonar system and a 16-cell Korean Vertical Launching System (K-VLS) that is able to deploy the K-SAAM, Hong Sang Eo anti-submarine missile, and Haeryong tactical land attack cruise missiles.

The hull design is generally based on the one of the Incheon class. However, as a part of weapon system modifications, the superstructure has been significantly changed. The hangar and a helicopter deck over the stern has been enlarged to support the operation of a 10-ton helicopter. [2] [3]
Cheonan was built by Hyundai Heavy Industries at its Ulsan shipyard and launched on 9 November 2021. [4] Cheonan was commissioned on 19 May 2023. [4]
On 22 January 2024, Commander Park Yeon-soo, who had served as the operations officer on ROKS Cheonan (PCC-772) when it was sunk by a North Korean torpedo on 26 March 2010 took command of the new Cheonan. [5]
