The United States has reportedly returned nuclear weapons to British soil for the first time since 2008, marking a significant shift in NATO’s nuclear posture and the UK’s own strategic deterrent capability. As reported by The Times UK, a U.S. military transport flight from Kirtland Air Force Base in New Mexico to RAF Lakenheath in Suffolk is believed to have delivered B61 nuclear gravity bombs—tactical weapons capable of being deployed by Britain’s new F-35A fighter jets.
The ten-hour flight by a C-17 Globemaster, tracked with its transponders switched on, appeared to be a “one-way drop-off,” according to William Alberque, a senior fellow at the Pacific Forum and former NATO nuclear non-proliferation director. He said the deliberate visibility of the flight path may have been intended to send a message to Russia, amid heightened tensions following the invasion of Ukraine and ongoing geopolitical instability.
RAF Lakenheath, the largest U.S. airbase in Europe, has undergone extensive upgrades in recent years—including hardened shelters and nuclear storage enhancements—to accommodate the return of American nuclear assets. The base previously hosted U.S. nuclear weapons throughout the Cold War, and was the first European site to do so.
A newly released UK Ministry of Defence policy document confirmed that American nuclear weapons will be stored at RAF Lakenheath and will be compatible with F-35A aircraft to be based at nearby RAF Marham in Norfolk. “This decision reintroduces a nuclear role for the RAF for the first time since the UK retired its sovereign air-launched nuclear weapons after the Cold War,” the statement read.
The UK’s procurement of 12 F-35A jets—capable of deploying B61 bombs—represents the country’s biggest expansion in nuclear delivery capability since the Cold War. Until now, the UK’s nuclear deterrent has relied solely on the Trident missile system aboard Vanguard-class submarines.
“This is significant both in terms of the basing of U.S. nuclear weapons at Lakenheath and in the broader strategic implications,” said Dr. Sidharth Kaushal, a military sciences expert at the Royal United Services Institute (RUSI). “It reintroduces a level of flexibility in NATO’s nuclear posture and marks the UK’s return to dual-capable air platforms.”
Analysts also pointed to symbolic cues that support the conclusion of a nuclear delivery. A recent “challenge coin” from the U.S. Air Force’s 493rd Fighter Squadron at Lakenheath reportedly features a mushroom cloud—interpreted as a nod to the unit’s nuclear mission.
Though neither the U.S. nor UK governments have confirmed the presence of nuclear weapons at Lakenheath, the circumstantial evidence and years of preparation suggest a clear return to Cold War-era nuclear arrangements, this time in response to modern threats from Russia and China.
“This isn’t just about deterrence,” Alberque added. “It’s about making sure our allies and adversaries alike know that NATO is rearming itself for the realities of today’s world.”
The UK is currently the only nuclear-armed state among the nine known powers to rely on a single delivery system. The return of a tactical air-based nuclear option marks a historic evolution in British nuclear policy—and a reaffirmation of the country’s role in NATO’s strategic defence.
