ECA Group Conducts Trials of its Steering Console Onboard South Korean Navy’s First Jangbogo III Submarine

ECA Group successfully performed the Sea Performance Trials Test of its Steering and Diving Console (SNDC) installed onboard the South Korean Navy’s first Jangbogo III Batch 1 submarine in 2019, the company announced.

The project began in 2014 when ECA Group was chosen to deliver the SNDC for the first batch (3 units) of Jangbogo III submarines. Since then, the deliveries occurred respectively in 2016, 2018 and 2019.

The SNDC for the first submarine, constructed at Daewoo Shipbuilding & Marine Engineering Co., Ltd (DSME), was delivered in 2016, the Factory Acceptance Test (FAT) was performed the same year. Three years later, in March 2019, the Setting To Work (STW) and Harbour Acceptance Test (HAT) were completed.

Finally, during the 2nd half of 2019, ECA Group’s team and DSME carried out tests on the SNDC in operational underwater conditions. These enforcement tests led to the confirmation of the performance of ECA Group’s Steering console as designed.

Korean Attack Submarine program (KSS)

The Korean Attack Submarine program (KSS) is a three-phased project to build up the Republic of Korea Navy’s attack submarine arsenal.

Through the first phase, KSS-I, the ROK Navy acquired nine 1,200-ton Chang Bogo class (German Type 209) submarines. For the second phase, KSS-II, the ROK Navy is acquiring a total of nine 1,800-ton Sohn Wonyil class (German Type 214) submarines equipped with Air-independent propulsion (AIP), in which eight are already in commission.

The third phase of the program, KSS-III, began in 2007. This class will have significant improvements when compared to its predecessors. A total of nine 3,000-ton KSS-III submarines are expected to be built in South Korea with indigenous technologies. It is expected that three batches, with three submarines each, will be built by 2029.

This new class will have a submarine version of the Korean Vertical Launching System (K-VLS or KVLS) which will be able to carry up to 10 indigenous Chonryong land-attack cruise missiles (LACM) and Hyunmoo submarine-launched ballistic missiles (SLBM), becoming the first submarine in the South Korean navy to have this kind of capability.

The new 83.3-meter-long, 9.6-meter-wide submarine can operate underwater for 20 days without surfacing and is capable of carrying 50 crew members.

For the KSS-III Batch 1, the first two are being constructed at Daewoo Shipbuilding & Marine Engineering Co., Ltd (DSME) and the third one is being constructed at Hyundai Heavy Industries (HHI).

The first KSS-III submarine, the future ROKS Dosan Ahn Chang-ho (SS-083), was launched on 17 September 2018 and will be handed over to the Korean Navy at the end of 2020 following two years of sea trials. The class is now named as Dosan An Chang-Ho-class Submarine after the lead boat of the class.
