The Daegu-class frigates (Hangul: 대구급 호위함, Hanja: 大邱級護衛艦) are defence frigates of the Republic of Korea Navy. The Daegu-class is an improvement of the preceding Template:Sclass-, and has otherwise been referred to an Incheon-class batch II, or FFX-II. 8 Daegu-class ships are planned, with the final goal of 20-22 frigates (of all types) in the ROKN. The Daegu-class vessels are to be built by Daewoo Shipbuilding & Marine Engineering (DSME).

Development

See also: Incheon-class frigate

The Daegu-class is a development of the Template:Sclass-, with many similarities, and many improvements. Modifications to the Incheon-clas include a 16-cell Korean Vertical Launching System (K-VLS) that will be able to deploy the Cheolmae-2 air defense missile, Hong Sang Eo anti-submarine missile, and Haeseong-II and Hyunmoo-3 land attack cruise missiles.

There will be a larger hangar for a 10-ton helicopter. Propulsion will be all-electric, with the twin gas turbine layout replaced with a single Rolls Royce MT30 turbine engine.
