IndoDefence 2025: Türkiye’s Roketsan and Indonesia launch ATMACA anti-ship missile co-production partnership.

On June 11, 2025, Roketsan, a leading Turkish defense firm, signed a landmark agreement with Indonesia’s PT Republik Defence Indonesia (RDI) for the joint production and delivery of ATMACA anti-ship cruise missiles. The agreement, formalized during the Indo Defence 2025 exhibition in Jakarta, marks a major milestone in Southeast Asia’s naval modernization. Amid growing Chinese maritime assertiveness, Indonesia is boosting its sea-denial capabilities through indigenous production supported by NATO-aligned technology. This move signals a deepening of bilateral defense ties and a shift toward regional self-reliance in missile manufacturing.

The ATMACA missile, developed by Roketsan, is an anti-ship cruise missile designed for high-precision, long-range maritime engagements. Designed to operate in all weather conditions, it boasts advanced guidance systems including GPS, INS, barometric and radar altimeters, and features an active radar seeker for precise targeting. With a range exceeding 250 km and a 220 kg high-explosive fragmentation/penetration warhead, the missile is capable of striking both static and moving maritime targets beyond the horizon. Its advanced data link allows in-flight mission updates, re-attack commands, and mission aborts, making it highly adaptable for dynamic combat environments. The missile’s modular design allows integration across naval platforms, including patrol boats, corvettes, and future submarine-launched configurations.

Originally unveiled in the 2010s and adopted by the Turkish Navy as a replacement for the U.S.-made Harpoon, ATMACA reflects Türkiye’s drive for defense autonomy. Its operational maturity was demonstrated through successful live-fire tests from platforms such as the Ada-class corvettes. The missile’s development also reflects broader trends in Turkish defense industry self-sufficiency and technological innovation. The collaboration with Indonesia underlines its export potential and confirms Roketsan’s positioning as a credible alternative supplier in the global anti-ship missile market. Compared to the Harpoon or China’s C-802, ATMACA offers competitive range, flexibility, and an attractive cost-performance ratio, especially when coupled with localized production options.

Strategically, this joint venture reshapes Southeast Asia’s naval defense equation. Indonesia, facing repeated maritime intrusions in its EEZ around the Natuna Islands by Chinese vessels, has prioritized anti-access/area denial (A2/AD) capabilities. The ATMACA deal not only enhances Indonesia’s deterrence posture but also strengthens its local defense industry through technology transfer and co-assembly. The geopolitical implications are twofold: it signals closer military-industrial alignment between Jakarta and Ankara, and it offers NATO-standard capabilities in a region often dependent on Western or Chinese systems. Indonesia becomes not only an operator but a potential supplier of missile systems in ASEAN, reinforcing its regional leadership ambitions.

Financially, the deal represents a substantial investment. Although the contract value has not been officially disclosed, the March 2024 agreement reportedly covered the delivery of 45 ATMACA missiles. With the addition of the co-production clause signed in June 2025 under a Joint Venture Agreement, the program will enable accelerated output, lower per-unit costs, and create a scalable production model for future exports. This is the second major Turkish-Indonesian defense cooperation after the KAAN fighter jet partnership. The Indonesian Ministry of Defense, under President Prabowo’s directive, is leveraging national industrial capacity to become a regional defense manufacturing hub. Given Indonesia’s demographic and industrial scale, this move could draw the interest of NATO partners seeking cost-effective, reliable missile systems beyond traditional supply chains.

The Roketsan-PT RDI partnership is more than a procurement contract, it’s the foundation of a long-term strategic axis in Indo-Pacific defense. With ATMACA joining the KAAN program in Jakarta’s growing portfolio of Turkish defense cooperation, Indonesia is clearly signaling its intent to not just import but jointly produce advanced systems. This approach capitalizes on its domestic industrial base and geopolitical relevance to become a bridge between NATO-standard technologies and Asian market needs. The precedent set by ATMACA could open the door to further joint production of naval and land-based systems, making Indonesia a pivotal player in both regional deterrence and global defense supply chains.
