Before the Royal Navy had enough communications specialists for permanent staffs, officers such as Somerville moved between Vernon, exercises, and flagships as operational needs demanded.

The conclusion invites viewers to look beyond ship-type labels and identify other communications specialists who reached senior command in the Second World War.
A defence review can look decades ahead while basing its initial equipment and force structure on the next five to ten years and testing new technology under realistic conditions.
