Jakarta – Indonesia is evaluating missile systems from Italy, France, and Türkiye to equip its newest warship, the KRI Prabu Siliwangi-321, as the nation continues to modernize its naval defenses. The frigate’s arrival in Jakarta on Thursday marks a significant step in bolstering Indonesia’s maritime security capabilities, particularly as it navigates complex geopolitical waters and seeks to protect its vast archipelago. The selection of the missile system will be a key factor in determining the ship’s overall combat effectiveness and its ability to respond to a range of potential threats, from piracy to regional disputes.
The KRI Prabu Siliwangi-321, built by Italian shipbuilder Fincantieri, is designed for a diverse set of missions, including patrol operations, surface and subsurface warfare, air defense, escort duties, maritime law enforcement, and humanitarian assistance. This multi-role capability is crucial for a nation like Indonesia, which possesses the world’s largest archipelagic state, spanning over 17,000 islands. The ship’s 143-meter length, and 16.5-meter beam provide a substantial platform for its array of weaponry and sensors. Indonesia’s strategic location along vital shipping lanes in the Indo-Pacific region underscores the importance of a robust naval presence.
Evaluating Missile Options
“We are still evaluating the missiles,” Indonesian Navy Chief Adm. Muhammad Ali told reporters during a press briefing. “There are options from Italy, from MBDA France, and possibly from Turkiye.” The decision, according to Admiral Ali, is still under review, with assessments ongoing regarding the optimal system to integrate with the ship’s existing capabilities. Even as the missile selection remains open, the ship’s primary gun systems have already been confirmed. This phased approach to equipping the vessel allows for careful consideration of interoperability and long-term maintenance requirements.
The potential Italian option likely centers around systems offered by Leonardo, a major defense contractor. MBDA France offers a range of missile solutions, including the Exocet anti-ship missile and various surface-to-air missile systems. Türkiye’s defense industry, increasingly prominent on the global stage, has been actively marketing its missile technologies, including the ATMACA anti-ship missile and the HISAR air defense system. Indonesia and Türkiye have been strengthening their defense cooperation, which could influence the consideration of Turkish missile systems.
First-of-its-Kind Gun Deployment
The KRI Prabu Siliwangi-321 is already equipped with an OTO Melara 127 mm main gun, a 76 mm Strales gun for medium-range air defense, 16 vertical missile launchers, Teseo Mk-2E anti-ship missiles, anti-submarine torpedoes, and close-range automated weapons systems. Notably, the ship recently completed live-fire testing of its 127 mm main gun, marking the first time an Indonesian Navy warship has operationally deployed a large-caliber gun exceeding 120 mm, according to Navy spokesperson Adm. Tunggul. This capability is intended to enhance the Navy’s ability to protect Indonesia’s maritime resources and enforce its sovereignty.
The structural firing tests, conducted before the ship’s departure from the Italian naval base in La Spezia on February 11, 2026, were a critical step in validating the weapon system’s integration and performance. The vessel made a brief stop in Lampung on March 23 before arriving in Jakarta. These trials ensured the ship’s readiness for a wide range of operational scenarios. Fincantieri, the shipbuilder, has a long history of constructing advanced naval vessels for international clients.
Strategic Implications for Indonesia
The arrival of the KRI Prabu Siliwangi-321 is part of a broader Indonesian naval modernization program aimed at addressing growing security challenges in the region. Indonesia has been increasing its defense spending in recent years, driven by concerns over territorial disputes in the South China Sea, piracy in the Malacca Strait, and illegal fishing activities in its exclusive economic zone. The new frigate will play a vital role in safeguarding these interests and maintaining regional stability.
The selection of the missile system will not only determine the ship’s immediate combat capabilities but as well influence Indonesia’s long-term defense partnerships. Choosing a system from Italy, France, or Türkiye could strengthen ties with those respective nations and potentially lead to further collaboration in areas such as technology transfer and joint military exercises. The Indonesian Navy is carefully weighing these strategic considerations alongside the technical specifications and operational requirements of each missile option.
The next step in the process involves a detailed assessment of the proposed missile systems, taking into account factors such as cost, performance, maintenance requirements, and compatibility with existing Indonesian Navy infrastructure. Admiral Ali has not provided a specific timeline for the final decision, but it is expected to be made in the coming months. Updates on the missile selection process will likely be provided through official Navy announcements and press briefings.
