RNAS Yeovilton was used as a V Bomber dispersal airfield
When I was at RAF Honnington with 90 Sqn Valiants from 1961 until the fleet was grounded we always dispersed to RNAS Yeovilton on a regular basis until we converted to in-flight refuelling role. We never actually dispersed in anger and if I remember correctly it was normally for exercise Mayflight.
The normal overseas base for 90Sqn during such operations or exercise Sunspot was RAAF Butterworth.
