The Republic of Korea Navy (RoKN) has received its first FFX-II-class guided-missile frigate ROKS Daegu (FFG-818), according to a statement on 1 February by South Korea’s Defense Acquisition Program Administration (DAPA).
Named Daegu (with pennant number 818), the 122 meter/400-foot-long ship was handed over to the service by Daewoo Shipbuilding and Marine Engineering (DSME) in a ceremony held at the company’s Okpo shipyard on Geoje Island. According to Jane’s Defence Weekly, it is expected to be operationally deployed from the second half of 2018.
Launched in June 2016, Daegu is the first of up to eight vessels of the class expected to enter service with the RoKN. The FFX-II class is a larger variant of South Korea’s six Incheon (FFX-I)-class ships, the first of which entered service in 2013.
According to specifications provided by DSME, the FFX-II class has an overall beam of 14 m/46 feet, a standard displacement of 2,800 tonnes, and a full-load displacement of 3,650 tonnes. The platform is powered by one Rolls-Royce MT30 gas turbine engine, and two DRS permanent magnet motors powered by MTU 12V 4000 diesel-generator sets, in a Combined Diesel-Electric or Gas (CODLOG) configuration. The ship can attain a maximum speed of 30 knot/34.5 mph/55 km/h.
The FFX-II class is armed with one 127-mm MK 45 MOD 4 naval gun and one Raytheon six-barrelled 20-mm Phalanx close-in weapon system mounted on the top of the aft superstructure.
It has also been equipped with a 16-cell Korean vertical launching system for surface-to-air missiles and anti-submarine rockets. The cells, each of which can be sub-divided depending on the type of missile, may also be used for land-attack missiles.
Also present on the ship are slant launchers for anti-ship and land-attack missiles, along with hull-mounted and towed array sonars as well as six 324-mm torpedo tubes for anti-submarine warfare.
South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) has launched the first of three Type 209/1400 diesel-electric submarines (SSK) on order for the Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut, or TNI-AL).
The boat was launched on 24 March at DSME’s Okpo shipyard in a ceremony attended by Indonesian defence minister Ryamizard Ryacudu and TNI-AL chief Admiral Ade Supandi. According to IHS Jane’s Defence Weekly, TNI-AL sources have confirmed that the submarine has been given the pennant number 403.
The vessel is part of a KRW1.3 trillion (USD1.1 billion) contract signed between DSME and the Indonesian Defence Ministry in December 2011. Under the contract the first and second vessels are to be built in South Korea, while the third boat will be produced at Indonesian state-owned shipbuilder PT PAL’s premises in Surabaya in a technology transfer arrangement.
According to specifications provided by DSME, the Indonesian Type 209, which displaces 1,400 tonnes dived, has a top speed of 21 knots/24 mph/39 km/h and a maximum operating range of approximately 10,000 nautical miles/11,508 miles/18,520 km at 10 knots/11.5 mph/18.5 km/h while surfaced.
The submarine has been designed for a range of missions, including Anti-Surface Warfare (ASuW), Anti-Submarine Warfare (ASW), mine laying, and special forces operations, said DSME in a statement on the launch.
The first boat will now undergo sea trials in South Korean waters and is currently scheduled for delivery by March 2017.
Work on the second vessel has begun and all three boats are expected to be delivered by the end of 2018.
