I have been told that the standard RAF Hangars were indeed a design factor for many RAF aircraft including the Vulcan. Not sure about the Victor 2 that was 9 feet greater.
The hangars were extremely advanced buildings incorporating split power supplies and utilities, blast doors and blow out roofs. Trenchard, I was told, was keener to get the RAF Infrastructure right and in the right places too, knowing that new aircraft would be transient whereas the hangars would persist for a long time.
Shame Sir Basil Embrey didn't plan ahead when he concreted east Anglia.
