Indonesia's Scorpène Submarine Program Begins Construction: What to Expect

Indonesia's Ambitious Submarine Program Enters a New Phase

Indonesia has taken a significant step towards enhancing its naval capabilities with the successful completion of the Scorpène steel cutting qualification at PT PAL's shipyard in Surabaya on December 12, 2025. This milestone signifies the country's readiness to enter the production phase of two Scorpène submarines, scheduled to begin construction in June 2026. The steel cutting marks the commencement of a domestic submarine construction program, a crucial move for Indonesia's naval independence.

The Importance of Technology Transfer

Part of this venture is the technology transfer from the French shipbuilder Naval Group, which will not only supply the designs but also train Indonesian engineers. The Scorpène program emphasizes Indonesia's long-term goal of achieving self-sufficiency in underwater technology and defense. The Director of Technology at PT PAL, Briljan Gazalba, states that the qualification is integral to the transition towards local production, thus strengthening the nation's defense capabilities.

Training and Readiness for Production

The qualification process included robust training for Indonesian engineers, who underwent extensive instruction at Naval Group's Cherbourg Welding Training Centre in France. This training equips them with the skills necessary to engage in various parts of the submarine construction, such as blasting, painting, and pre-outfitting. Furthermore, around 50 experts from Naval Group will assist in training over 400 Indonesian engineers, which not only boosts local expertise but also fosters international cooperation.

Regional Defense Collaboration

Alongside the support from France, Indonesia is also looking towards cooperation with India, which has shown interest in contributing to Indonesia's defense technology landscape. Discussions during a recent dialogue between Indonesian and Indian defense ministers underline the value of India's experience in submarine development, particularly from its own Scorpène-class program. This collaboration could bring additional strategic advantages for Indonesia, enhancing the operational scope and capabilities of its emerging submarine fleet.

The Future of Indonesia's Naval Defense

The Scorpène submarines are designed to meet modern operational challenges with advanced features such as a full lithium-ion energy system, enhancing their stealth and operational range. Beyond merely fulfilling current military needs, these submarines represent a leap towards Indonesia becoming a competitive player in maritime security within the Southeast Asian region.

Conclusion: The Path Ahead

As Indonesia embarks on this ambitious project, it is not just building submarines; it is establishing a framework for a sustainable national defense industry. The success of the Scorpène program will reflect Indonesia's commitment to sovereignty and progress in defense technology and capabilities.

With the domestic production of the Scorpène submarines setting off a new era for Indonesia’s naval forces, it is crucial for the nation to maintain momentum in training, production, and international collaboration to realize its defense aspirations fully. By investing in local talent and fostering partnerships, Indonesia is poised for a stronger maritime future.
