Aliquot
Alongside a single flight of B-1B "Lancer" bombers from RAF Fairford, the other visitors to Iran yesterday were a flight of B-2A "Spirit" bombers from Whiteman AFB (KSZL) in the mainland US. At present it's unclear how many bombers exactly (I'm sure we'll hear from CENTCOM at some point), but based on analysis of the tanker assets involved in the mission compared with previous B-2 runs, I believe 4 or more bombers is likely.
