F-35 fighter jet faces scrutiny over cost and dependence

The F-35 stealth fighter jet, developed by Lockheed Martin, continues to be a major focus in military procurement, with the Pentagon recently announcing an order for at least 850 additional units over ten years. Despite concerns about its high costs and the strategic dependence it creates on the United States, the aircraft has become a key asset for many European allies.

F-35 used by multiple NATO allies

About twenty U.S. allies, including the United Kingdom, Italy, the Netherlands, and Germany, use or have ordered the F-35 Lightning II. The aircraft is designed to replace older models and is considered more stealthy than European competitors like the French Rafale and the Swedish Gripen, thanks to its reduced radar signature and advanced data-sharing capabilities.

Belgian defense official highlights F-35's advantage

In 2025, Belgian Defense Minister Theo Francken emphasized that the F-35's stealth capabilities make it a superior aircraft compared to European alternatives. He stated that Russian President Vladimir Putin is not afraid of European fighters but is concerned about the F-35's ability to remain "invisible" on the battlefield.

Denmark faces criticism over F-35 purchases

In May 2025, Eric Trappier, CEO of Dassault Aviation, criticized Denmark for continuing to buy F-35s despite U.S. threats related to Greenland. The controversy has reignited concerns about military dependence on Washington, with some officials questioning the long-term benefits of the purchase.

Denmark underestimates F-35 costs

In June 2026, the Danish Audit Office found that the cost of acquiring and operating 27 F-35s over 30 years was underestimated by 14 billion Danish crowns, or about 1.9 billion euros. This has added pressure on the government to re-evaluate its military spending and cooperation with the U.S.

Canada reviews F-35 procurement

In March 2025, Canada initiated a review of its order for 88 F-35s due to trade tensions with the U.S. and threats from former President Donald Trump. Ottawa is now considering a mix of aircraft, including the Swedish Gripen, but has not abandoned its initial commitment to the first 16 F-35s.

F-35 sales to multiple NATO and non-NATO countries

The U.S. has sold more than 623 F-35s to 13 NATO allies and several non-NATO countries, including Japan, Australia, and South Korea. Despite criticism of its high operating costs and potential limitations in a Pacific conflict, the F-35 remains popular due to its stealth and interoperability with American forces.

F-35's development and production challenges

The F-35, produced by Lockheed Martin with engines from Pratt and Whitney, is often called a technological marvel. However, its development has faced challenges, particularly with software and system integration. Critics question its long-term sustainability and effectiveness in distant conflicts like those in the Pacific.
