Vulcan was trialled with a PWII fit - there is a photo somewhere of one with three PW mounted at the forward end of the bomb-bay, and IIRC, the potential load was for seven such weapons.
Also, if you look at the evidence which has since emerged via a commemorative seminar held at the purple learning centre, Admirals Lewin, Fieldhouse, Leach and Woodward were very keen on the thought of a Vulcan bombing the airfield, even though CAS had informed the war cabinet that to shut the runway he'd want to send at least 25 sorties and preferably more.
The reason for eagerness on the part of the senior dark blue was because of the signal that might be sent to the junta by carrying out a long range raid.
