Britain’s global ambitions have entered a new phase in 2025, as the Royal Air Force cements its posture as a forward-deployed, networked, and agile force within the Indo-Pacific region. The year has been marked by a series of high-profile operations and multinational exercises, with the RAF’s participation exemplifying the United Kingdom’s strategic tilt toward the Indo-Pacific.
In this context, operations such as Highmast, exercises like Talisman Sabre, and the dynamic Mobility Guardian deployment have underscored both the UK’s commitment to regional stability and its capacity to operate with allies and partners—including Australia, Japan, Canada the United States, the Republic of Korea, Singapore, and New Zealand—in a complex, contested environment.
The UK’s 2025 Integrated Review reaffirmed the Indo-Pacific as a region central to the nation’s security, prosperity, and global influence. Amid changing security threats like great power rivalry, navigation disputes, and state coercion, the RAF has adjusted its activities to strengthen deterrence, reassurance, and cooperation with partners. This strategic pivot is not merely symbolic; it is operationalised through persistent engagement, a robust exercise programme, and the deployment of cutting-edge capabilities such as the F-35B Lightning and the fleet of Air Mobility Force assets including Voyager, C-17 and A400M.
Operation Highmast, initiated in early 2025, stands as the RAF’s principal deployment in the Indo-Pacific. The majority of the fleet—including Typhoon FGR4s, Poseidon P8s, A400M Atlas, C-17 Globemasters, Voyager tankers, and F-35B Lightnings aboard HMS Prince of Wales, actively ensures safe passage, executes carrier resupply, and facilitates troop movement.
The explicit aims of Highmast are to demonstrate rapid reinforcement capability, to assure allies of Britain’s enduring commitment, and to refine the logistics required for sustained operations at range.
Participation in Operation Highmast has included Exercise Med Strike where the RAF deployed a contingent of Typhoon FGR4s, Voyager air-to-air refuelling tankers, and A400M Atlas transport aircraft to the Mediterranean theatre, where they trained alongside allied forces from NATO and regional partners. The exercise focused on integrating air power in joint maritime and land operations, simulating scenarios ranging from high-intensity combat missions to humanitarian assistance and disaster response. RAF crews engaged in dynamic air combat manoeuvres, coordinated precision strikes, and executed rapid deployment and extraction of personnel and materiel. Notably, Exercise Med Strike tested and enhanced the RAF’s interoperability with coalition partners, strengthening command and control structures, improving information sharing, and reinforcing the United Kingdom’s commitment to collective security in a strategically vital region. The lessons learned from Med Strike not only sharpen the RAF’s operational readiness but also fortify alliances that underpin stability across the Mediterranean and beyond.
Highmast has also tested the RAF’s ability to generate combat power from dispersed and minimally equipped airstrips, a skill crucial for survivability in a high-threat Indo-Pacific environment; F-35B’s short takeoff and vertical landing capability was especially valuable in these scenarios.
The backbone of all UK Operations and Exercise – the air mobility force (AMF) assets, including A400Ms, Voyager and C-17s, provide ongoing critical support as well as rapid response to seasonal cyclones and natural disasters anywhere in the world.
Operation Highmast’s success has strengthened defence ties and interoperability with partner nations, while providing the RAF with invaluable lessons on operating at range, managing logistics chains, and integrating with diverse command structures.
The biennial Exercise Talisman Sabre is the largest bilateral military exercise between Australia and the United States, but in 2025, it has reached a new milestone with expanded British participation and the inclusion of key Indo-Pacific partners such as Japan, the Republic of Korea, New Zealand, and Canada. For the RAF, Talisman Sabre presents a unique opportunity to operate alongside not only the Royal Australian Air Force (RAAF) and the US Air Force (USAF), but also the Japan Air Self-Defense Force, the Republic of Korea Air Force, the Royal Canadian Air Force, and the Royal New Zealand Air Force.
RAF contributions to Talisman Sabre include the deployment of F-35Bs and AMF assets such as Voyager aircraft embedded with allied squadrons, conducting combined air operations from forward-deployed locations across northern and western Australia. Integrated exercise ‘strike missions’ saw F-35Bs and Voyager fly complex sorties alongside coalition F-35s, F-22s, F-18s, and indigenous platforms, practising suppression of enemy air defences, dynamic targeting, and contested airspace operations. British Joint Terminal Attack Controller teams coordinated close air support missions, ensuring seamless communication and precision effects on the ground in support of allied land forces, while RAF specialists contributed to the joint cyber cell, simulating offensive and defensive operations against a sophisticated peer adversary. Notably, Talisman Sabre 2025 exercised a distributed command and control approach, with the RAF’s Air Battle Management teams integrating and fusing data from multiple domains, enhancing tactical skillsets and reinforcing the bonds of trust and interoperability that underpin the security architecture among partner nations.
Mobility Guardian, hosted by the United States Air Force Air Mobility Command, is a premier annual exercise focusing on logistics, air mobility, and sustainment that underpin operational success across the Indo-Pacific’s vast distances. The RAF’s involvement in Mobility Guardian 2025 is ongoing with the deployment of an A400M and specialist personnel currently in location. RAF transport aircraft have flown thousands of miles, moving personnel, equipment, and humanitarian supplies between partner nations and austere locations, often in close coordination with the USAF, RAAF, and JASDF to ensure operational reach throughout the region. The exercise showed the RAF can quickly set up and run operations from basic airfields, help coalition missions in tough situations, and work closely with allies on moving supplies, medical evacuations, and command tasks.
Mobility Guardian's focus on overcoming the “tyranny of distance” in the Indo-Pacific directly supports the RAF’s ability to reinforce allies and deter adversaries by enabling the rapid movement and sustainment of credible combat power.
Central to the success of the RAF’s Indo-Pacific operations in 2025 is the integration of advanced technologies and new operational concepts. Multi-domain integration has enabled RAF elements to operate as part of combined force, linking air, land, maritime, space, and cyber effects into a coordinated campaign. These innovations have not only advanced technology but have also led to doctrinal shifts, transforming how the RAF conceives of air power projection and operational endurance at strategic distances.
2025 has seen the RAF deepen its relationships with Indo-Pacific partners not only through operations and exercises, but through defence diplomacy initiatives as well. Popular exchange programmes and embedded billet opportunities have allowed personnel to serve as liaisons and planners within the headquarters of partner air forces, facilitating the sharing of best practices and harmonisation of procedures. The RAF has supported partner capability development through joint training and professional military education, particularly with smaller regional air forces such as those of Malaysia, Brunei, and the Philippines. Rapid response teams from the RAF have worked with ASEAN nations to deliver emergency aid and medical support in the wake of natural disasters, building trust and reinforcing the UK’s commitment to regional resilience. These efforts have strengthened the UK’s reputation as a reliable and proactive partner, further anchoring its influence within the Indo-Pacific alongside a constellation of committed nations.
While 2025 has been a year of progress, the RAF faces a dynamic threat environment in the Indo-Pacific, with evolving capabilities of potential adversaries contesting freedom of navigation and airspace, logistical complexities posed by geography and infrastructure limitations, and the necessity of constant adaptation in the face of rapidly advancing technologies and hybrid threats. Nonetheless, the RAF’s experience on Highmast, Talisman Sabre, and Mobility Guardian has yielded operational insights and strengthened partnerships that will shape British air power for years to come. By maintaining a forward posture, investing in interoperability, and embracing innovation, the RAF is well positioned to support the security and stability of the Indo-Pacific. The RAF’s operations and exercises in the region in 2025 have demonstrated the United Kingdom’s resolve and capability as a global air power, and through persistent engagement, technological innovation and commitment to partnership, the RAF continues to play a pivotal role in shaping the security environment of one of the world’s most dynamic and strategically significant regions.
