> There is not a single F-16 variant used anywhere in the world that has the full capabilities of their American counterparts ... The same holds for any other advanced fighter platform, including the F-35. This includes nuclear carry capability.

To be clear, I sourced that statement. Relevant bit from the article:

> In essence, the nuclear sharing agreement provides for member states of the military alliance without nuclear weapons to partake in planning and training for the use of nuclear weapons by NATO. ... Germany, Belgium, the Netherlands and Italy are all part of the sharing agreement. ... This agreement — American bombs guarded by American soldiers on a German base but flown by crews and planes of Germany's military forces, the Bundeswehr — dates back to the Cold War and NATO's nuclear deterrence strategy

Italy and Germany have the tornado. Belgium only has F16s which could possibly fulfill that role and will soon have the F35. Same goes for the Netherlands. So they do or will have DCA US made aircraft.

NATO's website:

> NATO’s nuclear deterrence posture also relies on the United States’ nuclear weapons forward-deployed in Europe, as well as on the capabilities and infrastructure provided by Allies concerned. A number of NATO member countries contribute a dual-capable aircraft (DCA) capability to the Alliance. These aircraft are central to NATO’s nuclear deterrence mission and are available for nuclear roles at various levels of readiness. In their nuclear role, the aircraft are equipped to carry nuclear bombs in a conflict and personnel are trained accordingly. The United States maintains absolute control and custody of their nuclear weapons forward deployed in Europe, while Allies provide military support for the DCA mission

And wikipedia:

> In 2022, after the Russian invasion of Ukraine, Germany announced that it would buy 35 F-35 jets to replace the Tornado in its nuclear sharing role. On 10 June 2013, former Dutch prime minister Ruud Lubbers confirmed the existence of 22 shared nuclear bombs at Volkel Air Base. ... In 2022, after the Russian invasion of Ukraine, reports appeared about the possible inclusion of Poland in the NATO nuclear sharing program.

That last bit is something I didn't know, but given Poland is also acquiring F35s, it makes sense.
