Birkenhead illustrates how support capacity can exist outside the dockyard fence. A Royal Naval Reserve headquarters across the Mersey has a gym, controlled access, and space that might anchor temporary accommodation for a carrier's personnel. Boats could move sailors across the river for duty rotations, making the arrangement possible in an emergency. The dock's proximity to a public road leaves a security weakness, limiting the arrangement to emergency use.
