Overview
- Exercise RUMMY, which took place on 20–21 October, saw RAF Typhoon fighters escort French Rafales in a simulated nuclear strike mission over France and the Mediterranean.
- French and British officials said the drill followed strict safety and security procedures, did not involve any real nuclear weapons, and kept decisions about use under national control.
- The flight marked a shift from British observers at prior French drills to active participation and implements the Northwood Declaration signed in July 2025 to coordinate independent nuclear forces.
- The exercise demonstrates conventional support for nuclear operations (CSNO), meaning non‑nuclear aircraft provide escort and protection without taking custody of weapons.
- Officials framed RUMMY as a deterrent signal responding to rising security threats in Europe and the story to watch next is whether more regular joint drills or wider European participation follow.
