Yes, at least six Swift F.2s were sent out to be used on the Maralinga range for Atomic proofing tests in op ‘Buffalo’.

I guess a subject like this will always have politics and tricky subjects (a later realisation of the effects on personnel of atomic tests example) attached, the subjects shouldn’t be avoided but certainly not solely dwelled on.

edit, just found this site (http://www.adf-serials.com/aa31.shtml) which lists the Swifts as F.1 WK199, F.2s WK215-‘217, ‘229, and ‘231. Probably alot more other relevant info on there aswel.
