In the gray, often overcast skies above Lincolnshire, a crucial series of tests recently concluded that could shape the future of air combat survival for NATO and its allies. In a significant display of defense cooperation, Sweden’s Defence Materiel Administration (FMV) joined forces with United Kingdom defense officials to wrap up the “Viking Flame” campaign. This weeklong evaluation, conducted in mid-November out of RAF Coningsby, wasn’t just a standard training exercise; it was a high-stakes data-gathering mission focused on the next generation of fighter jet self-protection systems. As military authorities describe it, the effort was a complex blend of radar technology, electronic warfare (EW), and threat simulation designed to prepare allied air forces for the increasingly dangerous environments they face today.
To understand the importance of Viking Flame, one has to look at the broader initiative behind it: Project Easyrider. Led by the Royal Air Force’s Air and Space Warfare Centre (ASWC) in close collaboration with the UK Defence Science and Technology Laboratory (DSTL), Easyrider is not your typical defense program. It is a classified, multifaceted effort born out of necessity. Modern warfare is changing rapidly, with adversaries developing sophisticated radar-guided and infrared missile threats that can lock onto aircraft from vast distances. Traditional procurement cycles—which can take years to move a technology from a blueprint to the cockpit—are simply too slow to keep up with these evolving dangers. Project Easyrider was designed to break that mold, serving as a fast-track platform that brings together operational users, scientific researchers, and international partners to test and field survivability technologies at a breakneck pace.
The Viking Flame campaign served as the latest proving ground for this initiative. Unlike standard drills that might focus on aerial dogfighting or ground attack runs, this campaign was entirely focused on the invisible war of electrons and sensors. The architecture of the tests was robust, utilizing both ground-based threat emulators and airborne assets to simulate near-peer threat conditions. In layman’s terms, the pilots and engineers were simulating a worst-case scenario where aircraft have to operate inside “Anti-Access/Area-Denial” (A2/AD) zones—airspace heavily defended by advanced Surface-to-Air Missile (SAM) networks designed to keep allied jets out.
Central to these trials were two Saab JAS 39 Gripen fighter jets from FMV Test and Evaluation (FMV T&E Luft). The choice of the Gripen for this campaign was strategic. Known for its ruggedness and smart design, the Gripen features a modular architecture that allows engineers to rapidly integrate new systems. This flexibility made it the perfect testbed for evaluating novel defensive systems, including new types of expendables (flares and chaff), jamming pods, and advanced sensor-fusion software. During the trials, these Swedish jets played a high-tech game of cat-and-mouse against simulated threats, testing how well the new digital electronic warfare suites could detect, jam, or decoy incoming missiles.
The execution of the campaign was no small feat. Over the course of five days, the teams successfully conducted six instrumented flights, battling the notoriously difficult November weather in the UK. Each sortie was meticulously tailored to simulate operationally relevant engagements. The pilots performed specific electronic attack maneuvers and countermeasure deployments, allowing the teams on the ground to collect high-fidelity data. This data is invaluable; it provides a foundational reference that will determine how these systems are integrated not just into the Gripen fleet, but potentially into other NATO fighter platforms, including both legacy jets and next-generation designs.
This collaboration highlights a deepening bond between Swedish and British forces. Planning and execution were a joint effort led by ASWC and DSTL, with heavy lifting provided by the Swedish Defence Research Institute (FOI) and the Swedish Air Force. The seamless technical interoperability demonstrated during Viking Flame reinforces the shared commitment to collective security. As Sweden integrates further into the NATO framework, exercises like this prove that their technology and doctrine can mesh perfectly with UK and broader alliance standards.
Ultimately, the Viking Flame campaign reflects an urgent push by Western forces to future-proof their air capabilities. The resurgence of peer-level threats means that air superiority is no longer guaranteed. By validating the performance of emerging countermeasures on a proven, export-ready fighter like the Gripen, Sweden and the UK have established a crucial baseline for joint air defense modernization. The results of these trials will ripple out far beyond RAF Coningsby, helping to shape survivability upgrades that ensure pilots can enter contested airspace, complete their missions, and return home safely.
