The United States holds significant leverage over Canada’s fighter jet selection through control of the Link 16 data-sharing system, essential for NATO and NORAD operations. If Prime Minister Mark Carney’s government opts for Sweden’s Gripen over additional F-35s, Washington could deny access to this critical technology.
Proven Interoperability in NATO Missions
Danish F-35s and Swedish JAS-39 Gripen-Cs operate seamlessly during NATO’s air policing mission in Iceland. Commanders from both air forces confirm strong performance during joint training at Keflavík airfield.
The aircraft share data via Link 16, a U.S.-developed system featuring advanced anti-jamming and encryption through the Multifunctional Information Distribution System (MIDS). Nations must secure U.S. approval to integrate this technology.
Potential US ‘Red Card’ on Gripen Integration
Lt.-Col. Johan Legardt, commander of Sweden’s NATO detachment in Iceland, warns of risks. “If Canada is the first country where the U.S. draws the red card then we have a problem,” he states, invoking the soccer referee’s ejection signal. Legardt notes no prior denials for Gripen buyers.
Trump administration officials indicate reluctance to share classified data on networks including Gripens, particularly within NORAD. U.S. Ambassador to Canada Pete Hoekstra warns that a Gripen purchase would require NORAD adjustments, prompting the U.S. to acquire more F-35s and increase patrols over Canada.
Defence expert Rob Huebert views this as plausible under current U.S. leadership. “Under the Trump era, is anything possible? Absolutely,” he says, while expressing hope for continued Canada-U.S. cooperation on NORAD modernization.
Saab Defends Gripen Capabilities
Saab asserts the Gripen-E meets Canada’s interoperability and security requirements, validated in the 2021 competition where it placed second. Spokesperson Sierra Fullerton highlights data exchange among Gripens, Saab’s Global Eye, and F-35s in Europe.
Former Saab pilot Jussi Halmetoja emphasizes no technical barriers exist with Link 16 installation. “They are very keen in keeping — and doing — interoperability, interconnectivity with all the allies, and with Canada,” he says, deeming U.S. denial unlikely.
Swedish Air Force commander Maj.-Gen. Jonas Wikman confirms joint exercises with Danish F-35s and German Eurofighters. “I expect the Gripen-E to be able to integrate in any co-operation when it comes to sensors and sharing information,” he states.
Royal Danish Air Force chief Maj.-Gen. Jan Dam echoes this: “We’ve made each other better and I think that’s what we’re gaining.”
Canada reviews its F-35 commitment amid trade tensions, with payments underway for 14 more jets and assembly started on 16 others. Saab proposes over 70 Gripens, promising thousands of local manufacturing jobs.
