Brunei Weighs Fast-Jet Options Amid Rising Regional Security Threats

"to deliver responsive air power in securing Brunei Darussalam’s territorial integrity and national interests."

Security context and the RBAirF’s stated mission

Brunei’s 60-year-old air force is adapting to "major power rivalry, regional and global conflicts, radicalization, and rapidly advancing disruptive technologies," according to the nation’s recent defense white paper. The Royal Brunei Air Force (RBAirF) has responded by planning upgrades across air defense and combat aviation, including medium-range ground-based air defense and a squadron of fast-jet combat aircraft to better protect sovereign airspace and the exclusive economic zone (EEZ).

Current fleet, immediate shortfalls, and training gaps

The RBAirF currently flies a small fleet of modern turboprops and helicopters. In May Brunei received the final two CASA (Airbus) C295W medium-airlift aircraft originally ordered in 2022, replacing older C235s in No. 15 Squadron for territorial and maritime surveillance, airlift, and humanitarian assistance. Rotary-wing assets include 12 S-70i Black Hawk helicopters and a handful of ageing BO105s slated to be replaced by six Airbus H145M multirole helicopters. Basic flight training rests on four Pilatus PC‑7 Mk.II aircraft that entered service in 1997 and are described as "in dire need for replacement."

Light turboprops as an affordable, multipurpose stopgap: Embraer A‑29 and Textron AT‑6

Embraer’s A‑29 and Textron’s T‑6/AT‑6 line are presented as dual-purpose choices: modern turboprop trainers that can also perform light combat roles. Both manufacturers market missionized, armed variants with electro‑optical/infrared sensors, laser-track sensors, gun and rocket pods, and precision-guided munitions. The report argues these aircraft could cover counterinsurgency, close air support (CAS), combat search-and-rescue, airborne forward air controller duties, helicopter escort, and border and maritime surveillance more efficiently than current RBAirF platforms—while also replacing the ageing PC‑7 fleet and keeping training largely domestic.

Advanced jet-trainers and light combat jets: Leonardo M346F and KAI FA‑50

For true fast-jet capability, the analysis recommends multirole advanced jet trainers with light-combat variants—specifically the Leonardo M346F Block 20 and the KAI TA/FA‑50 Block 70 family. Both come equipped with AESA radar, targeting pods, datalinks, helmet‑mounted sights, large‑area displays and the ability to carry air‑to‑air and air‑to‑ground weapons. Crucially, the FA‑50 family uses an afterburning F404 powerplant and can achieve supersonic speeds, giving it a range-and-speed advantage over the subsonic M346 for Quick Reaction Alert (QRA) duties across Brunei’s EEZ. Both types also serve Phase 3 (advanced) jet training and, with their sensors and weapons, can be used in lead‑in fighter training (Phase 4).

Training modernization: VLC, overseas training, and the time cost of fast-jet proficiency

Entering fast-jet operations will require a revised syllabus and modern training aircraft. The RBAirF could send pilots overseas for Phase 3–4 jet training—echoing the Singapore model—or join courses in Italy or Canada while keeping basic training at home. Alternatively, a turboprop-to-jet domestic pathway is possible. The report highlights Virtual, Live, and Constructive (VLC) training aids embedded in modern trainers as a force-multiplier: they can emulate radar and beyond‑visual‑range engagements so that a small number of live aircraft and simulators can deliver complex, large-force training at lower cost. The Philippine Air Force’s experience is cited as a caution: after returning to fast jets with 12 FA‑50PH delivered between 2015 and 2017, Manila only placed a follow-on order for 12 FA‑50 Block 70 aircraft in 2025, and the PAF’s recovery of fast-jet skills took years—illustrating that building operational proficiency can take a decade or more.

What this means for the Royal Brunei Air Force, the Philippine Air Force, and OEMs

• The Royal Brunei Air Force: faces a choice between a cost-effective, rapid pathway to enhanced surveillance and CAS with turboprop light combat trainers, versus a longer, more resource-intensive commitment to supersonic jet operations that will require new training regimes and sustained investment.
• The Philippine Air Force: serves as a regional reference point showing both the attraction of FA‑50‑class aircraft and the time required to regain and expand fast‑jet capability after a pause in fighter operations.
• Original equipment manufacturers (Embraer, Textron, Leonardo, KAI): will find a market pitch focused on training‑to‑combat synergies, VLC integration, and counter‑one‑way‑attack‑drone capabilities—features the report highlights as increasingly relevant.

Fast jets are understandable for a country that must defend a maritime EEZ and require QRA, but the route Brunei chooses should reflect more than platform-to-platform comparison. The pragmatic path on offer—modern trainers that double as light combat aircraft—promises immediate gains in training, persistence, and cost efficiency; a leap to full fighter status offers greater reach and speed but demands a decade of sustained training and investment. Brunei’s decision will define not only the RBAirF’s aircraft but the air force’s operational tempo and industrial relationships for years to come.
