Key Points

  • The navy's third FFX frigate is reported to have been received
  • The vessel, which will bolster South Korea's submarine prosecution capabilities, is scheduled to become operational in May 2015

The Republic of Korea Navy (RoKN) has received its third Incheon-class guided-missile frigate, delivered under the Future Frigate Experimental (FFX) programme, news agency Yonhap reported on 31 December.

The agency also cited the country's Defense Acquisition Program Administration (DAPA) as saying that the vessel, named RoKS Jeonbuk (pennant number 813), will become operational in May following a four-month integration process. The warship is expected to take on roles such as maritime surveillance and anti-submarine patrol.

Jeonbuk is the third ship in the class to be produced by shipbuilder Hyundai Heavy Industries. The company was also contracted to produce the first two vessels in class, Incheon (811) and Gyeonggi (812), commissioned in January 2013 and November 2014 respectively. Another local company, STX Offshore & Shipbuilding, has been contracted to produce ships four to six.

IHS Jane's Fighting Ships notes that a further nine ships are projected to enter service by 2020. This batch of nine will be built to a substantially revised design. Some estimates suggest that a class of up to 20 vessels in total may be procured.

The Incheon-class frigates are intended to replace the RoKN's Ulsan-class frigates and Dong Hae- and Po Hang-class corvettes. Equipped with Raytheon's Mk 49 RIM-116 Rolling Airframe Missile surface-to-air weapon, a Phalanx Block 1B close-in weapon system (CIWS), and a hull-mounted sonar, the platform offers improved anti-air warfare (AAW) and anti-submarine warfare (ASW) capabilities. IHS Jane's reported in January 2013 that the RoKN will deploy AgustaWestland AW159 Lynx Wildcat ASW helicopters on the Incheon class.

In August 2014 IHS Jane's reported that the frigates' six torpedo tubes will carry indigenously developed K745 Cheong Sangeo (Blue Shark) 324 mm torpedoes: these weapons have a speed in excess of 45 kt; they can also be operated in shallow waters such as the Korean peninsula's West Sea (Yellow Sea).

The Incheon-class frigates have a length of 114 m, a beam of 14 m, and a draught of 4 m. The frigates displace 3,200 tons at full load and can attain a top speed of 30 kt. They accommodate a crew of 140.

COMMENT

The effort to acquire platforms with submarine prosecution capabilities took on heightened urgency after the sinking of Po Hang-class corvette RoKS Cheonan in March 2010. A South Korean investigation concluded that the 1,200-tonne vessel was torpedoed near the Northern Limit Line (NLL) by a North Korean vessel believed to be either a Yono-class midget submarine or a Sang-O coastal submarine. Pyongyang has denied this.

The NLL, unilaterally declared by the United States military in the 1950s, is a demarcation that has not been officially recognised by North Korea. As such, the West Sea (Yellow Sea) has been the scene of repeated confrontations between the North and South, with both nations alleging incursions.

The sonar-equipped, ASW-focused Incheon-class frigates are expected to be central to the RoKN's effort to deter operations by North Korean submarines in these contested waters.

La 1ère turbine à gaz MT30 de Rolls Royce pour les frégates FFX Batch2 sud-coréennes a passé ses tests d'acceptation

La 1ère turbine à gaz MT30 de Rolls Royce pour les frégates FFX Batch2 sud-coréennes a passé ses tests d'acceptation | Newsletter navale | Scoop.it

LONDON, Sept. 16 (UPI) --Rolls-Royce is touting the passage of acceptance tests by its first MT30 gas turbine engine for the Republic of Korea Navy's FFX frigate program.

The engine, the "world's most power-dense marine gas turbine," will power eight Block II FFX ships being built by Daewoo Shipbuilding and Marine Engineering.

The MT30 is derived from Rolls-Royce aero engine technology, and produces 36 to 40 megawatts. It already powers the U.S. Navy's Freedom-class Littoral Combat Ships and will power the U.S. Navy's DDG-1000 Zumwalt class destroyer, as well as Britain's Queen Elizabeth-class aircraft carriers and Type 26 frigates.

"The MT30 is becoming the gas turbine of choice for many of the world's major naval program, with its inherent reliability and power density driving its selection," said Don Roussinos, Rolls-Royce' president of its Naval business. "The FFX II program is significant in that it will be the first application for the MT30 outside of the UK and US markets, and also the first ship to use a single MT30, alongside diesels."

Rolls-Royce said the MT30 engine will be shipped to Korea, where Hyundai Heavy Industries will integrate it into a steel enclosure which also houses the air inlets, exhausts and ancillary equipment.

Mise à l'eau de la frégate Chungbuk (5ème unité de la classe Incheon FFX) à Changwon

Mise à l'eau de la frégate Chungbuk (5ème unité de la classe Incheon FFX) à Changwon | Newsletter navale | Scoop.it

CHANGWON, 23 oct. (Yonhap) -- Une nouvelle frégate de 2.300 tonnes, baptisée Chungbuk, a été lancée aujourd’hui au cours d’une cérémonie à laquelle ont assisté le chef adjoint des opérations navales, Jung Ho-sup, et d’autres officiels de la marine.

La cérémonie s'est déroulée sur le chantier naval de STX Offshore & Shipbuilding Co. à Changwon, dans le sud du pays. Il s’agit de la cinquième livraison effectuée dans le cadre du projet visant à moderniser la flotte de la marine sud-coréenne. Le premier bateau, l’Incheon, a été livré en 2011. Le projet prévoit le lancement d’un total de 20 bateaux à l’horizon de 2020.

Le Chungbuk est long de 114 mètres et peut accueillir jusqu’à 120 personnes et naviguer à une vitesse de 30 nœuds (55,5 km/h), a-t-il été précisé. Il est aussi équipé d’un radar trois dimensions, d’un système de détection des torpilles et de missiles antiaériens, antinavires et anti-sous-marins.

Cette nouvelle frégate sera livrée à la marine à la fin de 2015 et se joindra à sa flotte en 2016.
