(DEFENCE SECURITY ASIA) — Indonesia’s Berani Mati naval drone struck a mock target off Tanjung Pasir on 12 November 2026, bringing a domestically developed one-way attack craft to an amphibious exercise that tested how the Indonesian Navy and Air Force work together.

The impact produced a visible explosion after a high-speed run, giving Jakarta a second public demonstration of PT PAL Indonesia’s prototype and raising a question for Indo-Pacific naval planners about whether the craft can become a sustained fleet capability.

The trial followed the main amphibious assault at Tanjung Burung, where 1,718 personnel took part in Latopsfib 2026, making the distinction between the joint landing and the subsequent drone demonstration central to assessing Indonesia’s progress.

By putting both events on one programme, the Indonesian Armed Forces, or TNI, linked conventional amphibious readiness with its interest in unmanned maritime systems, while the separate trial left integration with the landing force an open question.

Defence Minister Sjafrie Sjamsoeddin said the integration of sea and air power demonstrated the troops’ “readiness and professionalism,” tying joint performance to Indonesia’s active defensive strategy under its Perisai Trisula Nusantara doctrine for safeguarding national sovereignty.

TNI Commander General Agus Subiyanto described the craft as having useful range, an assessment that underlined the military’s interest in the platform while leaving planners without a published figure to assess its reach across Indonesia’s archipelago.

Navy Chief Admiral Muhammad Ali and Air Force Chief Air Marshal Mohammad Tonny Harjono were among the observers, placing the exercise within a broader assessment of joint readiness at a time when unmanned systems are increasingly prominent in planning.

The military presented the Banten run as an example of artificial intelligence assisting precision targeting, but the public account leaves open which decisions the software made, how much control the operator retained, and what the trial could establish about reliability.

The earlier Dabo Singkep demonstration, in August, showed the vessel leaving a ship’s well deck and striking a mock target, giving Indonesia separate evidence of shipboard launch and target contact in addition to the November high-speed demonstration off Banten.

The state-owned shipbuilder’s involvement gives the project industrial as well as operational significance, because Indonesia can draw on an existing naval construction and maintenance base as it assesses the distinct demands of supplying unmanned surface vessels to the fleet.

The timing of any fleet deployment remains uncertain in mid-November, with no publicly confirmed production order, fleet quantity or service-entry date, leaving the demonstrations as evidence of Indonesia’s industrial direction and military interest in the technology.

For Southeast Asian navies, the development adds a domestic Indonesian programme to regional discussion of maritime autonomy, with its eventual significance tied to procurement scale, safety assurance and Indonesia’s ability to support a new class of vessel over time.

What the Banten Amphibious Exercise Tested

Latopsfib 2026 culminated a progressive training cycle, giving the Indonesian military an opportunity to assess how personnel, ships and aircraft from separate services performed in a shared scenario, where the timing of each phase affected subsequent units.

Kopaska combat divers opened the Tanjung Burung scenario with beach clearance, a task that put a naval specialist unit at the start of the landing and made the handover to the landing force part of the joint readiness assessment.

Three Indonesian Air Force T-50 Golden Eagles provided close air support during the exercise, placing an air component inside the naval landing scenario and giving both services an opportunity to assess their ability to operate under a common command plan.

KRI Bung Tomo and KRI John Lie provided naval gunfire support, adding a ship-based element to the exercise and making the coordination of supporting fires a distinct part of the rehearsal for the Marine landing force.

Three waves of Indonesian Marines landed from KRI Semarang, putting the ship at the centre of the landing and underscoring how amphibious readiness depends on the availability of vessels that can carry and support the landing force.

Air Force Caracal and Super Puma helicopters joined Navy Panther and Bell aircraft in the exercise, widening the range of aviation assets involved and adding a requirement to coordinate air activity around a landing involving multiple ships and shore units.

The seizure and securing of the objective marked the end of the scripted landing, completing a sequence that allowed commanders to observe how Indonesia’s conventional forces worked together under the conditions established for the exercise.

The involvement of both services gave the exercise value as an assessment of interoperability, although completing the scenario leaves open how those formations would perform under disrupted communications, degraded visibility or other pressures absent from the public exercise record.

The move to Tanjung Pasir after the main landing gave the Berani Mati its own trial window, a detail that matters when assessing public claims about unmanned systems within Indonesia’s amphibious force structure and command arrangements.

Viewed as a force-posture event, Latopsfib displayed a conventional amphibious capability that Indonesia already trains across services alongside a prototype whose future role depends on decisions about procurement, crewing ashore and the responsibilities of the supporting fleet.

From Dabo Singkep to Tanjung Pasir

The Berani Mati made its public debut on 5 August 2026 at the integrated TNI exercise off Dabo Singkep in the Riau Islands, beginning a test record spanning two major exercises in distinct Indonesian coastal settings.

The August launch from the well deck of hospital ship KRI Dr Soeharso established that the prototype could launch from a host ship in a controlled exercise, a milestone with implications for the navy’s future transport and support requirements.

The August exercise featured a coordinated group scenario, but the public record provides limited evidence about the number of craft that could be managed routinely or the level of independence each vessel exercised during the reported swarm-formation demonstration in the Riau Islands.

Imagery from Dabo Singkep showed the craft intact after impact, consistent with a simulated payload event and showing more about the craft’s ability to reach its target than about the effects of its proposed strike configuration.

The November trial added a clearly visible explosion on contact with the mock target, although the public account leaves the explosive source and configuration unresolved, limiting what can be concluded about the effects of the strike payload described for the programme.

Around 55 knots was the speed figure associated with the Banten demonstration, giving readers a reference point for the programme’s emphasis on speed while leaving the vessel’s performance over longer periods and in different sea conditions outside the public record.

The two trials offer different evidence about programme maturity, with August demonstrating shipboard launch and November showing a high-speed run that ended in a visible impact, both within controlled exercises whose results cannot yet establish routine fleet performance at sea.

The August exercise also featured C-705 anti-ship missile firings, a reminder that the Indonesian Navy is evaluating unmanned vessels in a force that already fields conventional strike systems, each with its own support arrangements and place in the service’s investment plans.

The comparison between the trials is also a reminder that an exercise appearance can answer specific questions about a platform without settling wider issues of reliability, especially when the public record contains few details about how results were measured or repeated.

For regional observers, the dates mark a progression from public debut to a second high-profile demonstration in roughly three months, while the value of that tempo for assessing industrial maturity depends on how much testing and evaluation occurred between the events.

The Autonomy Claims Behind Berani Mati

Berani Mati is a compact unmanned surface vehicle conceived primarily for one-way attack, a design choice that gives the Indonesian Navy a different procurement problem from that of a reusable patrol vessel because each operational expenditure would create a replacement requirement.

The programme also envisages an intelligence, surveillance and reconnaissance configuration, which would give the vessel a different role and raise different questions about recovery, sensor utility and how information from an unmanned platform could be handled by an existing naval command structure.

The prototype carries a mast-mounted electro-optical sensor associated with navigation and observation, but the sight of that equipment on the hull reveals little about how consistently it can provide usable imagery across the varied visibility conditions found in coastal waters.

PT PAL’s design provides for remote operation and autonomous navigation along a pre-planned route, two control modes that place different demands on operators and make it important to distinguish a vessel’s ability to navigate independently from its authority to make engagement decisions.

The Banten exercise associated artificial intelligence with precision, while earlier programme material described automated identification of friendly and hostile targets as a development objective, leaving uncertainty about which functions had matured by November’s Banten demonstration.

A mock target in an exercise provides a defined test case, while civilian traffic and friendly military activity make target identification a more demanding issue in routine operations, particularly for an archipelagic navy responsible for waters used by numerous commercial and local operators.

The programme’s control system has been linked to PT PAL’s Kapal Selam Otonom, or KSOT, autonomous submarine, a relationship that could help Indonesia build a common base of engineering expertise while each platform still faces distinct environmental and certification demands.

Descriptions of the hull as low-observable remain qualitative in the public record, so the visible angular profile is evidence of a design choice while its effect on detection under different conditions remains an open question for any independent assessment of the craft.

The absence of published dimensions, displacement and fuel capacity makes it difficult to gauge the prototype’s broader footprint, particularly when comparing the space and support requirements of an unmanned surface vehicle with the boats a prospective host ship already carries.

For commanders assessing emerging autonomy, the important distinction is between a successful run in a defined scenario and evidence that operators can supervise the craft reliably across repeated missions, with clear responsibility for decisions throughout an operation involving other vessels.

The Logistics Behind a Fleet Capability

A well-deck launch offers a starting point for evaluating shipboard compatibility, while an operational assignment would also require a host ship to allocate space, crew time and maintenance support alongside the other craft and equipment carried for its existing duties.

KRI Dr Soeharso’s role in the August trial demonstrated the flexibility of a ship with a well deck, but the public record leaves fleet planners without a list of approved launch platforms or any indication of how broadly that compatibility has been tested.

Operating a fleet of unmanned craft would put recurring demands on technical personnel, training facilities and spares, so any assessment of the project’s affordability needs to consider the support organisation as well as the price of an individual vessel.

PT PAL has described Berani Mati as suitable for relatively fast and economical production, but the absence of a published unit cost, procurement quantity or delivery schedule leaves the industrial claim without the benchmarks needed to judge a future acquisition.

The speed of a prototype programme can signal engineering momentum, whereas sustained production would test how consistently the shipbuilder and its suppliers can deliver equipment, documentation and support across successive batches with the same standards expected of an operational fleet.

The prospect of shared technology with KSOT gives the navy a reason to examine potential efficiencies in training and support, although those gains would depend on how much equipment and software are genuinely common once the two programmes reach operational configurations.

One-way craft pose a different accounting problem from reusable vessels, because their initial acquisition cost captures only part of what the navy would spend on readiness, including the equipment and personnel needed to operate and support them over time.

The public gaps on range and endurance are especially consequential for Indonesia, where the distances between operating areas affect whether a platform can be supported by existing bases and ships and how much of the fleet could realistically use it.

A counter-USV capability poses its own resource question for regional fleets, since assessing unfamiliar small craft calls for trained crews and reliable identification alongside whatever protective systems a navy fields, with procurement choices shaped by the maturity of the threat.

The transition from prototype to regular naval inventory will therefore be visible in milestones beyond demonstrations, including a funded order, published service-entry plans and evidence that the navy has organised the personnel and infrastructure to keep the system available over time.

What Indonesia Is Signalling to the Indo-Pacific

Indonesia’s Perisai Trisula Nusantara doctrine frames the Banten exercise as part of an active defensive strategy, and the public introduction of Berani Mati links that posture to a domestic industry capable of putting its own unmanned prototype through joint exercise trials.

The setting matters for interpreting Jakarta’s signal, because the demonstration took place alongside a national amphibious readiness exercise whose stated focus was sovereignty and interservice cooperation, giving the announcement an institutional context beyond the performance of the craft itself at sea.

For Southeast Asian defence establishments, Indonesia’s decision to develop the craft through a national shipbuilder places emphasis on who controls future production, maintenance and upgrades, questions that shape procurement choices even where different navies pursue broadly similar unmanned missions at sea.

PT PAL’s established work on warships and submarines provides a foundation for the programme, while unmanned vessels also bring software management and operator oversight into focus as areas that can determine how confidently a navy relies on domestically produced hardware.

A credible programme could expand the Indonesian Navy’s options within a conventional fleet, while its impact on the regional balance would depend on the quantity brought into service, the extent of training and the readiness that Indonesian units could sustain.

Recent conflicts have increased attention to unmanned maritime systems, but the political and practical significance of Berani Mati rests on how Indonesia adapts the concept to its own geography, institutional arrangements and demands on the navy in peacetime as well as crises.

The exercise also linked military activity to local outreach through community service in Teluknaga under Indonesia’s total defence concept, placing the public presentation of a new maritime technology alongside an established effort to maintain relationships with communities near training areas.

Across the Indo-Pacific, the spread of unmanned naval programmes increases the importance of identifying vessels and interpreting their behaviour, particularly in crowded waters where military activity, civilian navigation and routine maritime security operations can occur in proximity to one another.

The highest-confidence conclusion from Banten is that Indonesia can bring a locally developed prototype to successive major exercises and publicly demonstrate target contact, an industrial and institutional milestone whose operational weight still depends on evidence that the fleet can absorb it.

The next measure of the programme’s strategic significance will be whether Indonesia commits resources to making Berani Mati a recurring part of naval readiness, turning the Banten demonstration into an acquisition decision with identifiable consequences for budgets, force structure and regional maritime planning.
