As Biggus says this is a gesture deployment, the air component FW, and to a limited extent RW, aircraft to counter the drone threat are fulfilling the necessary roles.
A BM threat to the Sovereign Bases would almost certainly originate from Hezbollah acting as a proxy rather than Iran itself as is suspected of the drone attack, and is unlikely to materialise.They are believed to have a limited number of Fateh-110s. As I have implied before, the presence of the US's noisy, black "weather balloon" probably made Akrotiri a legitimate target in the eyes of the IRGC, I suspect the drone was a one off and won't be repeated.
