ROKS Donghae (FFG-822)

ROKS Donghae (FFG-822) is the fourth ship of the Daegu-class frigate in the Republic of Korea Navy. She is named after the city, Donghae.

Development
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 on stern has been enlarged to support the operation of a 10-ton helicopter.

Construction and career
ROKS Donghae was launched on 29 April 2020 by Hyundai Heavy Industries and expected to be commissioned in 2021.
