South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) has handed over the second of three Nagapasa (Type 209/1400)-class diesel-electric submarines (SSKs) ordered by the Indonesian Navy (Tentara Nasional Indonesia-Angkatan Laut: TNI-AL) in 2011.

The TNI-AL received the 61.2 m-long boat, which will be known as KRI Ardadedali (with pennant number 404) once commissioned later this year, in a ceremony held on 25 April at DSME’s Okpo shipyard on South Korea’s Geoje Island, according to a company statement.

The boat, which displaces about 1,400 tonnes when dived, was launched in October 2016. Powered by four MTU 12V493 diesel engines, the submarine has a top speed of 21.5 kt when dived and 11 kt when surfaced.

Ardadedali , which has a crew complement of 40, is part of a KRW1.3 trillion (USD12.1 billion) contract signed between DSME and the Indonesian government in December 2011 for three SSKs.

First-of-class KRI Nagapasa (with pennant number 403), which was also built by DSME, was commissioned in August 2017, while a third vessel, Alugoro , is currently under construction at the facilities of Indonesian shipbuilder PT PAL in Surabaya, with delivery expected by 2021.

As Jane’s reported, the Nagapasa class is equipped with the Wärtsilä ELAC KaleidoScope suite of sensors, which consists of a cylindrical array sonar (CAS), a flank array sonar (FAS), an acoustic intercept sonar (AIS), and a mine avoidance sonar (MAS).
