The United Kingdom has announced plans to acquire 12 F-35A stealth fighter jets capable of carrying nuclear weapons, marking the return of a nuclear air-strike capability for the Royal Air Force for the first time since the Cold War.
The decision, revealed ahead of the NATO summit in The Hague, represents a major shift in Britain’s defense strategy and nuclear posture. Once delivered, the aircraft will provide Britain with a second nuclear delivery platform in addition to its existing Trident submarine-based deterrent.
The move brings the UK closer in line with allies like France, who already maintain both sea and air-based nuclear capabilities.

The F-35A fighters, unlike the UK’s current F-35B jets which operate from aircraft carriers but are not nuclear-capable, will be integrated into NATO’s airborne nuclear mission. These aircraft are designed to carry American B61 nuclear bombs, which are stored at key NATO locations across Europe. The United States will retain control over the use of these warheads.
With this acquisition, Britain becomes the latest NATO member to field dual-capable aircraft alongside Germany, Italy, and others. Downing Street described the move as “the biggest strengthening of the UK’s nuclear posture in a generation,” reinforcing NATO’s European defense pillar amid growing uncertainties about American nuclear guarantees in the event of a Russian aggression.
The announcement came alongside a wider government security review, which warned of a shifting global order and rising threats.
The review called for expanded defense capabilities, highlighting the need for “greater lethality, warfighting readiness, and deeper munitions stockpiles.” It also flagged the potential for future armed conflict directly affecting British territory.
The renewed emphasis on defense was also underscored by Prime Minister Keir Starmer’s commitment to a new NATO spending target. Britain will allocate 5 percent of its GDP to national security by 2035, with 3.5 percent dedicated to military expenditures and 1.5 percent to other related infrastructure and security areas.
The strategic shift was informed by a recent defense report led by former NATO Secretary-General George Robertson, which identified Russia as a primary threat and called for expanded naval capabilities and renewed investment in nuclear deterrence.
However, the increased defense spending comes amid domestic financial strain and public concern over cost-of-living issues. Critics have questioned how the military commitments will be funded and whether they may impact other national priorities.
Despite these concerns, the government insists that in today’s “era of radical uncertainty,” national security must take precedence to ensure long-term peace and stability.
