PT PAL Cuts First Steel for Indonesia’s Advanced Scorpène Evolved Submarine Program in Surabaya


 


Marking a historic milestone for Southeast Asian naval defense capabilities, state-owned shipbuilder PT PAL Indonesia officially hosted a first steel-cutting ceremony at its Surabaya shipyard for the country's inaugural Scorpène Evolved submarine. Conducted in the presence of senior defense leadership, including Indonesian Navy Chief of Staff Admiral Muhammad Ali, the landmark event formally transitions the multi-billion-dollar acquisition program from contractual planning into physical manufacturing. The ambitious undertaking is structured to fortify national maritime sovereignty while fundamentally expanding Indonesia's domestic defense-industrial autonomy.

The program—formalized under a strategic contract between the Indonesian Ministry of Defense, PT PAL, and France's Naval Group—encompasses the domestic construction of two advanced diesel-electric attack submarines. Unlike standard export variants, the Scorpène Evolved design tailored for Jakarta replaces traditional air-independent propulsion systems with high-capacity lithium-ion battery configurations. This cutting-edge energy storage layout provides superior safety standards, expanded usable energy reserves, reduced battery charging times, and greater underwater endurance.

Technically, the new boats will measure approximately 72 meters in length with a submerged displacement hovering near 2,000 tonnes. Designed to operate at depths exceeding 300 meters while achieving underwater speeds greater than 20 knots, the vessels are optimized for both blue-water deterrence and shallow-water archipelagic patrols. Armed with heavy F21 torpedoes, anti-ship missiles, and naval mines managed via Naval Group's advanced SUBTICS combat system, the platforms will introduce formidable undersea strike power to the region.

Crucially, the foundational framework of the enterprise relies on an intensive, multi-layered transfer of technology (ToT) agreement rather than simple platform acquisition. Under the guidance of a permanent contingent of French experts, hundreds of Indonesian engineers and certified welders who completed rigorous prerequisite training in Cherbourg will execute local hull fabrication, mechanical outfitting, electrical systems integration, and final weapon assemblies directly within PT PAL's specialized facilities.

With the lead submarine’s construction timeline estimated at roughly 96 months—targeting final delivery around 2032—the program represents a transformative leap for Indonesian shipbuilding. By mastering the complex tolerances and acoustic silencing requirements demanded by modern submarine manufacturing, Jakarta is ensuring that future maintenance, modernization, and sovereign design iterations can be sustained entirely by local industry.
