Why joint plans cannot be assigned to another service

The Baltic concept depended on an army being available in the correct place and willing to serve a naval landing scheme. The same problem appears in proposals to use the British Expeditionary Force as a projectile for naval strategy without first securing Army agreement. A pre-Second World War Royal Air Force plan assigned Royal Navy carriers to ferry aircraft east before returning for the Fleet Air Arm. That unilateral approach was one of several factors in the interservice dispute over control of naval aviation and the Inskip Award. A service therefore needs a staff that can work with other staffs, build political support, and produce a common plan open to criticism and revision.
