WASHINGTON — In a move that has shaken the defense world to its core, Australia is reportedly withdrawing from its multi-billion dollar F-35 commitment — and quietly targeting the Swedish Gripen as a replacement. What seemed like a decided alliance decision is now no longer certain.

The news, first reported by defense industry sources late yesterday, has sent shockwaves through the Pentagon and raised urgent questions about the future of the U.S.-Australia military partnership. For nearly a century, Australia has been Washington’s most reliable ally in the Pacific. That assumption is now crumbling.

Insiders say this strategic pivot depends on multiple factors, but the unexpected change aims to break free from dependence on U.S. systems. If true, this is not a minor adjustment in procurement. It is a strategic signal — one that Washington did not anticipate.

The F-35 has long been the crown jewel of Western air power. Built by Lockheed Martin, it is the most advanced fifth-generation fighter in existence, used by the U.S. Air Force, Navy, and Marine Corps, as well as over a dozen allied nations. But the aircraft has also been plagued by cost overruns, maintenance challenges, and availability rates that have disappointed several international partners.

What about the Gripen? Built by Swedish aerospace giant Saab, the JAS 39 Gripen offers a different philosophy entirely. Cheaper — at roughly $60 million per unit compared to the F-35’s $110 million. Faster to deploy, with significantly lower maintenance requirements. And critically, it is designed for autonomous operation from highways and remote airstrips, making it far less dependent on vulnerable fixed airbases.

A different philosophy. A different game.

The causes of this potential shift are deeply rooted in Australia’s evolving defense strategy. On Wednesday, Defense Minister Richard Marles unveiled the government’s 2026 National Defence Strategy, which emphasizes “self-reliance” as a core principle . While Marles publicly defended the U.S. alliance as “indispensable,” the strategy makes clear that Australia can no longer assume unconditional American support .

“Self-reliance should not be confused with military self-sufficiency,” Marles told the National Press Club. But he also acknowledged that the U.S. increasingly expects its allies to invest more in their own defence and reduce their reliance on American military power . The F-35, as a platform deeply dependent on U.S. logistics, software updates, and weapons systems, suddenly looks like a vulnerability rather than an asset.

The effect of this potential rejection would be catastrophic for American defense contractors. Australia had been expected to purchase up to 100 F-35s over the life of the program, representing billions in revenue for Lockheed Martin and its supply chain. Losing that order would not only harm the bottom line — it would signal to other allies that American technology is no longer the default choice.

And here is the interesting point: if Australia truly changes strategy, other U.S. allies might begin asking the same uncomfortable question. Do we need American technology — or just an alliance with the United States? Nations from Canada to Germany, from Japan to the United Arab Emirates, are all watching Canberra’s decision closely.

The Gripen offers particular advantages for Australia’s vast geography. With a shorter takeoff distance, lower fuel consumption, and the ability to operate from roads, it aligns perfectly with the “strategy of denial” that Canberra has adopted — defending the northern approaches from dispersed, resilient bases rather than relying on a handful of major airfields that could be targeted by Chinese missiles .

Industry sources say Saab has already begun informal discussions with Australian officials. The Swedish government, which maintains a policy of non-alignment, is seen by some in Canberra as a more predictable partner than an increasingly erratic Washington. “The U.S. has become unreliable,” one Australian defense insider told this newspaper. “We need platforms we can control, not platforms that can be turned off from Colorado Springs.”

Washington’s reaction has been muted but anxious. The Pentagon declined to comment on what it called “speculative reporting.” But privately, officials acknowledge that losing Australia on the F-35 would be a devastating blow — not just financially, but symbolically. The alliance that won World War II, fought in Korea, Vietnam, Iraq, and Afghanistan, is showing cracks that no missile defense system can patch.

The coming weeks will determine whether this is saber-rattling or genuine strategy. Australia remains committed to AUKUS and the Virginia-class submarine program, suggesting that Canberra is not abandoning the U.S. entirely. But on fighter aircraft, the calculus appears to be shifting. And if Australia goes Gripen, the question will echo from Oslo to Tokyo: if not the F-35, then what?
