On 4/9, USAF C-17 AE4F12 as RCH4614 departed Kirtland for Kleine Brogel AB, Belgium. It refueled with a KC-135 as FLAM## along the way, indicating it possibly had a hazardous cargo on board and arrived at Kleine on the 10th.

Kleine AB is home to the 701st Munitions Support Squadron whose primary mission is handling B61 nuclear weapons.
Today (4/14) USAF C-17 AE1239 as RCH4614 departed Volkel AB en route to Kirtland AFB, NM. It likely refueled along the way (as indicated by the lack of a fuel stop) possibly indicating a hazardous cargo on board.

Given the above, this was likely a mission to swap out B61s in storage at Kleine & Volkel ABs with freshly maintained weapons direct from Kirtland.
As of 0500z, 11 states had declared states of emergency and 1 state (Texas) has issued a preemptive disaster declaration.

These actions are taken to trigger emergency powers that allow executive leadership to bypass certain requirements (such as competitive contracting rules) in order to swiftly and effectively manage the emergency.

I believe the first flight of B-61 nuclear weapons were delivered to the newly updated facility at RAF Lakenheath, UK yesterday by US Air Force C-17A Globemaster III #AE2FAC as RCH4574 following the pattern of similar nuclear swaps.
