(DEFENCE SECURITY ASIA) — Indonesia’s successful F-16 and Super Tucano highway landings in East Java on 22 October 2026 have advanced a contingency basing programme aimed at preserving air operations when conventional runways become unavailable, placing infrastructure resilience alongside aircraft capability in national defence planning.

The Indonesian Air Force, designated TNI AU, used the Pasuruan–Probolinggo Toll Road for its second highway landing exercise this year, extending a programme whose strategic significance rests on reducing dependence on a limited number of established military airfields.

Two F-16 Fighting Falcons and two EMB-314 Super Tucanos participated, supported by two Caracal helicopters, demonstrating that a prepared civilian road could accommodate different aircraft categories while exposing the coordination requirements behind even a temporarily dispersed air operation.

The approximately 3.5-kilometre operating strip, extending from kilometre 834 to kilometre 837+500, offered sufficient length for the exercise, but its roughly 24-metre width imposed tighter handling margins than the conventional military runways against which the programme is being assessed.

Air Force Chief of Staff Air Chief Marshal Mohamad Tonny Harjono described the activity as safe and smooth, while the programme’s broader direction envisages additional surveyed locations that could expand Indonesia’s options for recovering aircraft during disruption.

For an archipelagic country comprising more than 17,000 islands, the underlying operational challenge is maintaining usable connections between aircraft, supporting personnel and infrastructure when a damaged runway interrupts the established geography of military aviation and emergency response.

DSA’s assessment is that the exercise strengthens contingency planning by demonstrating an additional recovery location, although the available information does not establish whether highway detachments could sustain repeated armed sorties under attack or prolonged pressure on their supply arrangements.

The distinction matters because landing an aircraft demonstrates access, whereas generating combat power requires fuel, weapons, maintenance, communications and protection to converge at a location whose civilian purpose normally takes precedence over military activity and operational security requirements.

The East Java event followed the inaugural Lampung trial on 11 February 2026, giving the programme a second geographical reference point while leaving unanswered how quickly additional sites could become available without the preparation associated with scheduled demonstrations.

Deputy Defence Minister Donny Ermawan Taufanto previously linked the concept to Sistem Pertahanan Semesta, Indonesia’s total defence approach, positioning civilian infrastructure as a contingency resource when disruption to primary bases threatens the continuity of national air operations.

Potential follow-on locations around Jakarta and Lombok indicate an ambition to broaden the network, but surveys and inter-agency coordination remain essential prerequisites, and the supplied information identifies no firm public schedule for the next full landing exercises.

The immediate strategic message is therefore measured but consequential: Indonesia is testing ways to preserve access to the air after infrastructure disruption, while the programme’s eventual military value will depend on how effectively supporting capabilities follow its aircraft.

A Narrow Highway Tests More Than Pilot Skill

The Paspro exercise required a straight road section with suitable pavement strength, acceptable approaches and manageable surrounding obstacles, illustrating that contingency runway selection depends on engineering suitability rather than simply identifying a long, apparently unobstructed stretch of highway.

Preparations included temporarily removing the central barrier, modifying markings, deploying portable runway lights and establishing roadside air traffic control, converting transport infrastructure into an aviation operating surface through coordinated physical changes and procedures that ordinary road operations do not require.

Technical teams checked the surface and operating environment, while the exercise incorporated rehearsals before the main event, demonstrating a preparation process whose safety benefits also complicate assumptions that an unmodified road could immediately substitute for an unavailable airbase.

The roughly 24-metre width was substantially narrower than the 45–60-metre military runway widths cited in the supplied material, making directional control and lateral clearance central constraints when evaluating the practicality of repeating these operations in different conditions.

Coastal conditions near Java’s northern shoreline introduced crosswind considerations, adding an environmental variable to a demonstration whose outcome cannot automatically establish equivalent safety margins at other locations, with different aircraft configurations or during less favourable operating weather conditions.

The Super Tucano conducted an initial low-level runway check before the F-16 sequence, while the broader activity included landings, takeoffs and additional manoeuvres, providing opportunities to assess approaches and aircraft handling on the prepared road throughout the exercise.

Operating both aircraft types widened the demonstration’s relevance, but it did not establish that every Indonesian combat aircraft could use the same strip, because suitability would require separate assessment of each platform’s operating requirements and planned deployment configuration.

The participation of aircraft from established squadrons connected the road trial to existing force structure, with F-16s drawn from Skadron Udara 3 at Iswahjudi and Super Tucanos from Skadron Udara 21 at Abdulrachman Saleh, linking contingency operations to home-base support.

Successful execution without reported incidents supports the narrow conclusion that the selected aircraft could operate from this prepared section, while the information provides no detailed performance data establishing landing weights, braking margins or sustained use across repeated operating cycles.

For planners, the meaningful engineering achievement is a validated relationship between a particular road, selected aircraft and controlled procedures, creating a foundation for further assessments rather than establishing universal interchangeability between Indonesia’s toll-road network and its military runway infrastructure.

Dispersed Operations Complicate Airbase Targeting

The programme addresses a fundamental vulnerability of concentrated airpower: aircraft depend on usable operating surfaces, meaning disruption to a small number of primary runways can constrain flight operations even when aircraft and aircrew remain available for further missions.

Prepared highway strips could reduce that dependence by offering alternative locations for recovery or repositioning, forcing any adversary assessing Indonesia’s air operations to consider a wider infrastructure network rather than concentrating exclusively on established airbase locations and runway availability.

That potential benefit concerns resilience rather than immunity, because a publicly identifiable road strip remains a fixed geographical feature, and its usefulness would depend on availability, protection and supporting arrangements when the contingency requiring its activation actually occurs.

DSA assesses that dispersal could complicate an opponent’s operational planning by increasing the locations requiring consideration, although the supplied material does not quantify additional targeting demands or demonstrate how a prepared highway site would perform against continuing surveillance.

The programme shares a conceptual emphasis with Agile Combat Employment and established Nordic highway operations, but those comparisons describe a common preference for distributed basing rather than proving equivalent Indonesian readiness, logistical capacity or operational maturity across different forces.

Indonesia’s version must account for archipelagic geography, where creating an alternative strip on one island does not automatically resolve the movement of fuel, personnel and equipment needed to support aircraft operating elsewhere across the country’s extensive maritime territory.

This makes the provincial coverage ambition strategically significant, because geographically distributed alternatives could provide more local contingency choices, although the existence of a suitable strip would still need to be matched with practical arrangements for activation and aviation support.

Harjono’s stated objective of eventually providing each province with at least one suitable alternate strip indicates a nationwide planning direction, but it remains an aspiration rather than evidence that Indonesia already possesses a functioning provincial network of operational highway bases.

The force-posture implication is a potential shift towards distributing selected activities beyond permanent airfields, while conventional bases would remain essential sources of maintenance, supplies and organisation for the aircraft and support elements moving through those temporary locations during contingencies.

Strategic signalling follows from demonstrating that runway disruption may leave alternative operating options, but the credibility of that message will grow only as repeated exercises establish how reliably Indonesia can activate, supply and use those options under demanding conditions.

Fuel and Maintenance Will Determine Combat Value

The most consequential question after the landing demonstration is how much operational activity the strip could sustain, because aircraft availability depends on the supporting logistics footprint as well as the ability to touch down safely and depart again.

The supplied material describes simulated refuelling and rapid turnaround preparations, including elements characterised as consistent with hot-pit procedures, but it does not establish a fully demonstrated capability to conduct repeated combat turnarounds with engines running at the highway location.

That distinction prevents a rehearsal detail from becoming an unsupported readiness claim, particularly when no verified turnaround times, fuel quantities, weapons handling results or sortie-generation rates are provided to measure the exercise against a sustained operational deployment requirement.

Fuel provision would determine whether a road strip functions mainly as an emergency recovery point or supports further flying, while the organisation of maintenance personnel and equipment would influence how quickly aircraft could return to available operational tasking.

Weapons support would add another requirement if the intended role expanded to armed sortie generation, but the available information does not demonstrate highway rearming, identify deployed munitions or establish the procedures used to support any such activity during the exercise.

Communications and command arrangements would similarly determine how effectively a temporary detachment remained integrated with wider air operations, making the roadside control tower an important exercise component without proving the full command architecture required during a contested military deployment.

Protection would remain necessary because moving aircraft away from a permanent airbase redistributes their exposure rather than removing it, and the supplied information does not describe an integrated air defence arrangement capable of protecting the temporary strip during operations.

The logistics problem also creates a force-structure trade-off, because distributing aircraft across more sites would require deciding how support personnel and equipment are allocated without weakening the established bases responsible for sustaining the wider air force during disruption.

A larger network could therefore provide more geographical choices while placing additional demands on coordination, with its value depending on whether support packages can reach the locations selected rather than on the number of surveyed road sections alone.

The decisive measure of progress will be demonstrated operational continuity after relocation, including how aircraft are serviced and returned to use, rather than treating successful landings as a complete proxy for the resilience of Indonesia’s combat aviation system.

Civilian Roads Create Military Options and Activation Constraints

The Paspro road closure reportedly began on 19 October and extended until 22 October, showing that this scheduled exercise relied on substantial preparation and traffic management rather than demonstrating immediate conversion of a busy highway during an unexpected contingency.

Traffic diversions through alternative toll gates allowed the selected section to become available, making transport authorities and road operators operationally relevant partners whose decisions would influence when military aircraft could safely access infrastructure normally serving civilian movement and commerce.

The programme’s emergency-only framing preserves that distinction, with officials emphasising that toll roads retain their primary transport function, a limitation that makes activation procedures central to readiness rather than a secondary administrative issue surrounding the aircraft demonstration itself.

Removing barriers and installing temporary aviation equipment established the required operating environment, but the information does not specify conversion time under emergency conditions or show whether equivalent preparations could be completed while transport demand remained unusually high nearby.

The Lampung trial similarly required road closures, diversions and technical coordination, reinforcing the point that civilian infrastructure becomes a useful defence resource through prior agreements and preparation rather than through pavement strength and runway length considerations alone during contingency planning.

Public Works Deputy Minister Diana Kusumastuti described that earlier success as a reference for future dual-use infrastructure planning, linking the aviation trials to decisions about road design that could influence the availability of suitable operating sections for future contingencies.

Incorporating requirements during construction could reduce the need for later modifications, although the supplied material provides no comparative cost data establishing the savings or demonstrating how particular design choices would affect construction budgets and subsequent civilian road operations over time.

The same evidence gap limits claims that highway strips offer a quantified financial alternative to new airbases or an aircraft carrier, because no programme budget or comparable assessment of operational outputs is available in the information supplied for this article.

Their clearest demonstrated advantage is exploiting selected existing infrastructure for contingency aviation, while recognising that an alternate runway provides a different operational function from a complete airbase or a naval platform capable of moving aircraft operations across maritime distances.

Civil-military integration is therefore central to the programme’s military mechanism, because infrastructure access, road engineering and public traffic management collectively determine whether a planned alternative becomes usable when conventional aviation facilities are unavailable during an emergency or other serious disruption.

Jakarta and Lombok Will Test Whether the Network Can Scale

The next phase centres on identifying additional locations, with Cibitung–Cilincing around Jakarta and prospective infrastructure in Lombok among the most prominently discussed options, suggesting that future activity could extend the programme beyond its two completed demonstrations in Sumatra and Java.

Cibitung–Cilincing has been described as meeting initial technical requirements, but that preliminary assessment should remain distinct from a completed aviation trial, because further verification and coordination would determine whether it can support the aircraft operations envisaged by planners.

Lombok presents a different planning opportunity through coordination over proposed road construction, potentially allowing dual-use considerations to enter infrastructure design earlier, although the supplied material does not establish a completed strip, an approved exercise date or an operational deployment plan.

Other named candidates include Jakarta–Cikampek II Selatan, Banda Aceh–Sigli and Probolinggo–Banyuwangi, but their inclusion in planning discussions does not establish equivalent readiness, particularly where extensions, technical reviews or longer-term design decisions remain part of the preparation process for emergency use.

Proposed usable lengths of approximately 3.5 kilometres for Jakarta–Cikampek II Selatan and 3.8 kilometres for Banda Aceh–Sigli illustrate location-specific planning, while Harjono’s broader reference to roughly 3,000 metres provides an aspiration rather than a universal certification standard for every candidate.

Scaling the programme would require consistent assessment of pavement strength, width, obstacle clearance and approaches, alongside an understanding of the different support demands each location would impose on aircraft detachments operating beyond their normal base infrastructure during temporary deployments.

Future exercises would add particular analytical value by clarifying activation times, turnaround performance and support requirements, because those measures would show how the programme progresses from establishing physical access towards maintaining useful aviation activity after an actual disruption occurs.

The strategic consequences would grow if multiple locations became reliably available across major islands, providing commanders with more recovery and repositioning choices while reducing the dependence of contingency plans on the continued availability of individual primary runways during emergencies.

For Indo-Pacific observers, the development highlights how infrastructure resilience can influence airpower without an immediate change in aircraft numbers, although the extent of that effect remains contingent on the logistics, protection and readiness supporting each alternative operating location.

Indonesia’s latest highway landing exercise has therefore established another practical contingency option, while the next test is whether a wider network can deliver repeatable operational continuity, turning carefully prepared road access into dependable support for airpower when established bases cannot function.
