UK Expands Nuclear Capability with Purchase of F-35A Stealth Jets

In a historic move, the United Kingdom announced on June 25, 2025, that it would purchase 12 F-35A stealth fighter-bombers during the ongoing NATO summit in The Hague. This acquisition marks the UK's renewed capability to deliver nuclear weapons via air, a role it had all but retired since the Cold War concluded. With this addition, the UK seeks to bolster its nuclear deterrent alongside its existing Trident submarine fleet, which can launch cruise missiles.

These advanced aircraft, capable of carrying both conventional and nuclear munitions, enhance Britain's response options during crises, particularly in light of heightened tensions in Europe. Furthermore, the UK will partake in NATO's airborne nuclear mission, which involves utilizing American B61 bombs stored in Europe. This transition, according to Downing Street, represents a significant enhancement of the UK's nuclear posture in over 25 years and responds to uncertainties regarding America's commitment to defending Europe against potential aggressors like Russia.

Other NATO members, including Germany and Italy, have similar dual-capable aircraft positioned within Europe, highlighting a broader alliance strategy to maintain a credible nuclear deterrent. The UK’s existing fleet of F-35B jets, although capable of operating from aircraft carriers, does not possess the ability to deploy nuclear warheads, making this new purchase a critical integration into the nation's defense capabilities as it evolves its military strategy in an increasingly complex geopolitical environment.
