KRI Alugoro (405), the Indonesian Navy’s third Nagapassa-class submarine and the first submarine to be assembled in Indonesia, has started sea trials.
This was announced by Indonesian shipbuilder PT PAL who shared photos of the submarine underway, adding that the sea acceptance trials started on January 3.
Built under a transfer of technology agreement with South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME), the submarine was expected to be commissioned by the end of 2019 after it was launched in April last year.
PT PAL revealed no details on why the submarine’s delivery was delayed or when it is scheduled for delivery to the navy.
The first two submarines were delivered from DSME’s shipyard in South Korea in 2017 and 2018. Indonesia has another US$ 1 billion contract in place with DSME for the construction of an additional three submarines in the class.
Once the additional three units are delivered, Indonesia can be expected to operate a fleet of eight diesel-electric submarines.
Nagapasa-class boats measure 61 meters in length and displace 1,400 tonnes. They are equipped by Aselsan-developed Zoka acoustic torpedo countermeasures.
