Steering Console of ROK Navy’s Third Jangbogo III Submarine Passes Factory Acceptance Test

France’s ECA Group successfully passed the Factory Acceptance Test of the Steering and Diving Console (SNDC) for the third Jangbogo III (KSS-III) Batch 1 Submarine for the Republic of Korea Navy (ROKN), in early summer 2019.

As part of the Jangbogo III Batch 1 program launched in 2014 by the South Korean Navy, ECA Group was awarded the supply of Steering and Diving Console for three submarines. The delivery of the equipment was started in 2016 for the first submarine and continued in 2018 for the second one.

In June 2019, ECA Group alongside Hyundai Heavy Industries (HHI), in charge of the manufacturing of the third submarine, successfully carried out the Factory Acceptance Test of the steering and diving console (SNDC) to be installed on the third submarine.

“This successful collaboration confirms ECA Group’s capability to smoothly run projects with first-time customers”, said a company statement.

The next steps for the Jangbogo III program include:

+ Training for both maintenance staff and operators
+ Setting To Work (STW) – planned next year.

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.
