Singapore Airshow 2026: Indonesia Moves to Replace Hawk Jets with Leonardo M-346 F Block 20

(DEFENCE SECURITY ASIA) –Indonesia’s accelerating drive to recapitalise its airpower is unfolding against a backdrop of intensifying Indo-Pacific security competition, where regional air forces are rapidly modernising to counter emerging high-end and asymmetric threats.

This strategic momentum was underscored at the Singapore Airshow 2026 when Leonardo formally announced the signing of a Letter of Intent with PT ESystem Solutions Indonesia and the Ministry of Defence of the Republic of Indonesia to collaborate on the supply, support, and long-term sustainment of the M-346 F Block 20 multirole trainer-fighter platform for the Tentara Nasional Indonesia-Angkatan Udara.

The announcement on 4 February 2026, following Jakarta’s July 2025 selection of the M-346 platform, marks a pivotal inflection point in Indonesia’s fleet renewal strategy as it seeks to replace increasingly obsolescent BAE Systems Hawk 109/209 aircraft whose operational relevance has eroded in the face of modern air combat threats, advanced unmanned systems, and network-centric warfare environments.

“This collaboration not only enhances our national defense capabilities but also fosters industrial growth, creating jobs and building expertise in advanced aerospace technologies,” said Habib Boukharouba, Chief Executive Officer of PT ESystem Solutions Indonesia, a statement that encapsulates Jakarta’s determination to align force modernisation with domestic industrial deepening under its Minimum Essential Force doctrine.

Carlo Gualdaroni, Co-General Manager Business of Leonardo and Chief Commercial and Business Development Officer, reinforced the strategic framing by stating, “The M-346 F Block 20 is a game-changer for air forces seeking versatility in training and operations,” adding that Leonardo is “proud to partner with Indonesia in this modernization journey, leveraging our proven platform to meet the evolving demands of Indo-Pacific security.”

Taken together, these statements reflect more than a procurement milestone, instead signalling a deliberate recalibration of Indonesia’s airpower architecture at a time when regional air forces are fielding fifth-generation fighters, long-range precision munitions, and integrated air defence systems that challenge legacy training and light-attack platforms.

For Indonesia, the M-346 F Block 20 acquisition intersects directly with its expanding fleet of advanced combat aircraft, including 42 Dassault Rafale fighters ordered at an estimated cost exceeding USD8.1 billion (approximately RM38.1 billion), creating an urgent requirement for a training ecosystem capable of replicating high-end combat conditions without imposing excessive cost or airframe fatigue on frontline assets.

As Southeast Asia’s largest archipelagic state, responsible for policing more than 17,000 islands and vast exclusive economic zones, Indonesia faces a uniquely complex air sovereignty challenge that demands rapid response, dispersed basing, and high pilot proficiency across diverse operational theatres.

Against this backdrop, the LOI signed at Singapore Airshow 2026 represents the foundation of a long-term capability transformation rather than a simple aircraft purchase, embedding training, light combat, sustainment, and industrial localisation into a single strategic framework optimised for Indonesia’s evolving security environment.

Replacing the Hawk: Closing a Critical Capability Gap in TNI-AU Training and Light Combat

The impending retirement of Indonesia’s BAE Systems Hawk 109/209 fleet has long represented a looming vulnerability in the TNI-AU’s force structure, as these aircraft, introduced in the 1990s, were designed for an era of permissive airspace and limited electronic warfare threats that no longer reflects the Indo-Pacific operational reality.

While the Hawk has served Indonesia reliably in advanced jet training and light attack roles, its analogue avionics, limited sensor fusion, and constrained weapons integration increasingly restrict its ability to prepare pilots for modern multirole fighters operating in contested electromagnetic environments.

Maintenance challenges, spare-parts availability, and escalating lifecycle costs have further eroded Hawk fleet readiness, particularly in a region where sanctions regimes, global supply chain disruptions, and geopolitical frictions routinely affect legacy Western and Russian platforms.

The selection of the M-346 F Block 20 directly addresses this gap by introducing a platform purpose-built to bridge the divide between basic jet training and frontline fighter operations, enabling Indonesia to compress pilot training pipelines while improving operational realism.

Unlike legacy trainers, the M-346’s embedded tactical simulation allows pilots to rehearse beyond-visual-range engagements, cooperative targeting, and electronic warfare scenarios without the need for extensive external assets, dramatically enhancing training efficiency and survivability awareness.

For the TNI-AU, which operates a heterogeneous fleet including Su-27/30 Flankers and F-16 Fighting Falcons alongside Rafale, standardising advanced training around a NATO-compatible digital backbone reduces doctrinal fragmentation and improves interoperability.

This is particularly relevant as Indonesia expands participation in multinational exercises with ASEAN partners and extra-regional powers, where data-link compatibility, sensor fusion, and mission command proficiency are increasingly decisive.

In operational terms, the M-346 F Block 20’s light combat capability further allows Indonesia to offload lower-intensity missions—such as maritime patrol augmentation, counter-insurgency, and air policing—from high-end fighters, preserving expensive airframe hours and reducing overall operating costs.

By replacing the Hawk with a platform optimised for both training and limited combat, Jakarta closes a long-standing capability gap while simultaneously future-proofing its pilot development pipeline against the rapidly advancing technological baseline of regional air forces.

M-346 F Block 20: A Digital-Era Trainer-Fighter for High-Threat Environments

At the core of Indonesia’s selection is the M-346 F Block 20 itself, an advanced evolution of Leonardo’s M-346 Master family that has accumulated more than 150,000 flight hours across nearly 160 aircraft operated worldwide, validating its maturity and reliability.

Unveiled in 2024, the Block 20 configuration represents a substantial technological leap, integrating digitalisation, artificial intelligence-enabled training functions, and enhanced mission systems designed to replicate the cognitive and tactical demands of next-generation air combat.

The redesigned cockpit replaces six traditional multifunction displays with two Large Area Displays per seat, complemented by a low-profile Head-Up Display optimised for night vision goggle compatibility, augmented reality overlays, and high-density data presentation.

This architecture allows pilots to train in environments closely mirroring fifth-generation fighter cockpits, improving human-machine interaction, decision-making speed, and situational awareness under high information load conditions.

The integration of an Active Electronically Scanned Array radar introduces true beyond-visual-range engagement training, allowing simulated and live employment of medium-range air-to-air missiles such as the IRIS-T while familiarising pilots with modern sensor management.

Link 16 connectivity further embeds the M-346 within network-centric operations, enabling participation in composite air operations with F-16s, Rafales, and allied aircraft, a critical requirement for coalition interoperability in the Indo-Pacific.

Electronic countermeasures and self-protection systems provide exposure to contested electromagnetic conditions, ensuring pilots develop survivability instincts before transitioning to frontline platforms.

Powered by twin Honeywell F124-GA-200 engines producing 6,280 pounds of thrust each, the aircraft achieves a maximum dive speed of Mach 1.15, a climb rate of 22,000 feet per minute, and supports a payload of up to 3,000 kg across seven hardpoints.

For Indonesia, this combination of performance, sensors, and systems positions the M-346 F Block 20 as both a training asset and a credible light combat platform capable of operating across the country’s vast maritime and littoral spaces.

Ground-Based Training and Rafale Integration: Building a Seamless Pilot Pipeline

One of the decisive factors underpinning Indonesia’s M-346 selection is Leonardo’s integrated Ground-Based Training System, which fuses Live, Virtual, and Constructive environments into a single ecosystem designed to maximise training output while controlling costs.

This approach allows pilots to rehearse complex missions involving multiple aircraft, airborne threats, and command-and-control elements, with virtual entities seamlessly integrated into live sorties.

For air forces transitioning to advanced fighters, this methodology dramatically reduces the number of expensive flight hours required on frontline aircraft while accelerating tactical proficiency.

Indonesia’s acquisition of 42 Rafale fighters, valued at over USD8.1 billion (approximately RM38.1 billion), amplifies the importance of such a system, as preparing pilots for the Rafale’s sensor fusion, electronic warfare suite, and networked operations demands a high-fidelity training environment.

The M-346’s ability to emulate Rafale mission systems and tactical workflows ensures a smoother transition, reducing conversion timelines and operational risk.

Leonardo’s experience operating the International Flight Training School, where pilots from multiple nations train on the M-346, further underpins the credibility of this model.

For the TNI-AU, the integration of the M-346 into its training continuum enables a coherent progression from basic jet training through advanced tactical preparation to frontline deployment.

This coherence is essential as Indonesia balances a mixed fleet of Western and Russian-origin aircraft, each with distinct operational philosophies and support ecosystems.

By anchoring training around a digitally advanced, interoperable platform, Jakarta reduces fragmentation and builds a pilot cadre capable of operating effectively across diverse mission sets and coalition frameworks.

Industrial Localisation and Strategic Autonomy under the MEF Doctrine

Beyond operational considerations, the LOI’s emphasis on localisation, maintenance, and human capital development reflects Indonesia’s broader strategic objective of enhancing defence industrial autonomy under its Minimum Essential Force doctrine.

PT ESystem Solutions Indonesia’s role in establishing local maintenance, repair, and overhaul capabilities for the M-346 family has the potential to create a sustainable aerospace support ecosystem, reducing reliance on overseas facilities and shortening turnaround times.

Such localisation aligns with Jakarta’s long-standing push to embed technology transfer and domestic participation into major defence acquisitions, ensuring that capital expenditure translates into long-term industrial capacity.

From an economic perspective, local MRO and training infrastructure can generate skilled employment, stimulate ancillary industries, and position Indonesia as a regional support hub for other M-346 operators.

This industrial dimension also carries strategic weight, as self-reliant sustainment mitigates the operational risks associated with sanctions, export controls, or geopolitical pressure from supplier nations.

In an Indo-Pacific environment increasingly shaped by great-power rivalry, Indonesia’s ability to maintain operational readiness independent of external political dynamics represents a significant strategic advantage.

The M-346 programme therefore functions not only as a capability upgrade but as a catalyst for deeper industrial and technological integration within Indonesia’s defence sector.

As negotiations progress toward a formal procurement contract, the scale and scope of localisation commitments will be closely watched as an indicator of Jakarta’s leverage and long-term intent.

Ultimately, the Singapore Airshow 2026 LOI signals Indonesia’s determination to pair advanced airpower capabilities with industrial resilience, reinforcing its position as a strategically autonomous actor in Southeast Asia’s evolving security architecture.
