PT PAL Indonesia and France’s Naval Group have launched construction of the Indonesian Navy’s first two Evolved Scorpène-class submarines at PT PAL’s shipyard in Surabaya, marking a major step in Indonesia’s submarine modernization programme.
The construction follows the defence agreement signed in 2024 between Indonesia’s Ministry of Defence and Naval Group for the acquisition of the advanced Scorpène diesel-electric attack submarine platform, supported by comprehensive technology transfer and local industrial participation.
As part of the programme, Indonesian personnel received specialized training in Cherbourg, France, where they gained expertise in advanced submarine welding techniques, structural engineering, mechanical and electrical integration, and quality control procedures required for submarine production.
The programme reached an important milestone when steel cutting began two months ahead of schedule. This followed a rigorous certification process that validated PT PAL’s workforce, production facilities, and manufacturing capabilities to meet international submarine construction standards.
Commenting on the achievement, Naval Group Programme Director Vincent Vimont stated that the milestone reinforces PT PAL’s position as a trusted strategic partner capable of supporting sophisticated defence manufacturing projects.
Enhanced Scorpène Design
The Evolved Scorpène submarines will feature modern lithium-ion battery propulsion, Naval Group’s SUBTICS combat management system, six 533 mm weapon tubes, and the ability to deploy heavyweight torpedoes alongside Exocet anti-ship cruise missiles, according to Naval News.
The submarines are expected to deliver an operational range of more than 8,000 nautical miles and an endurance of up to 80 days without requiring frequent port visits, significantly enhancing Indonesia’s maritime defence capabilities.
Delivery of the lead vessel is planned for 2032, while the second submarine is expected to enter service in 2033. Beyond strengthening Indonesia’s naval fleet, the programme is projected to create around 2,250 employment opportunities and expand the country’s indigenous submarine manufacturing expertise.
