Second sub continues navy modernisation [INDODEF16-D2]

02 November 2016

South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) (Hall D, Stand 294) has officially launched KRI Trisula, the second of three DSME 209 class submarines on order for the Indonesian Navy (TNI-AL).

The inauguration ceremony, performed at DSME’s Okpo shipyard on 24 October, marks another milestone in the modernisation of the TNI-AL’s submarine fleet.

Having previously refitted two German-built Type 209/1300 boats for the TNI-AL, DSME was in December 2011 awarded a US$1.1 billion contract to build three new DSME 209 submarines for the service. This deal was the single largest defence export contract won by a South Korean company and signalled DSME’s arrival as a major player in the international submarine market.

Evolved from the German Type 209/1200 originally licensed to DSME in the late 1980s, the DSME 209 variant being supplied to the TNI-AL includes a Kongsberg-supplied MSI-90U Mk 2 command and weapon control system, and a Safran navigation suite (incorporating two Sigma 40XP laser gyro inertial reference units, a computer, and safety-critical navigation software).

Lead submarine KRI Nagabanda was launched at Okpo in March this year, and commenced sea trials in September. Handover is planned for March 2017. KRI Trisula is expected to begin sea trials in early 2017 and delivery is scheduled for October.

A keel-laying ceremony for the third boat, destined to become KRI Nagarangsang, was marked at Okpo last May. According to the TNI-AL, the third unit will be transferred to the Surabaya yard of PT PAL at the end of this year for completion in Indonesia.

Delivery is planned by the end of 2018.
