The first of class Incheon was built at Hyundai Heavy Industries (HHI) and is scheduled to be commissioned in summer 2013. Eight ships are planned for the FFX class which is to replace the present Ulsan class and will be built at HHI and Daewoo Shipbuilding & Marine Engineering (DSME). A further 18 ships are projected to enter service by 2020 to replace the Po Hang and Dong Hae classes.

The Incheon Class is a coastal defence frigate of 2,300 displacement with an LOA of 374 ft (114 m) and beam of 46 ft (14 m). Unlike previous Korean frigate designs, this propulsion system is a two shaft CODAG arrangement but uses only a single gas turbine where previously two turbines were specified. The MT 30 gas turbine delivers up to 36MW of power and diesel engines provide for lower power requirements. The maximum speed is 30 kn and cruising speed is 18 kn giving a range of approximately 4,500 nm.

The gas turbines will be built and tested in the UK prior to delivery to Hyundai Heavy Industries (HHI) who is carrying out the integration with the module enclosure that includes the air inlets, exhausts and ancillary equipment.

Rolls-Royce is supplying this engine for the U.S. Navy's DDG-1000 Zumwalt class destroyer and Freedom class Littoral Combat Ships as well as the UK Royal Navy's new Queen Elizabeth class aircraft carriers.
