Sal, do you have a mission statement for the force, accompanied by a series of prioritised task statements?
Eg:
Mission
The X Sub-sector fleet is to provide an ongoing High Guard for the prevention of disruption to trade and travel between the worlds of X.
Groupings and Task
Battle Squadron
1. Provide First Response component to check or channel foreign invasion force.
2. Maintain interoperability capability with neighbouring Sub-sector fleets
3. Be prepared to operate as part of a IN relief TF or TF element.
Cruiser Squadrons
1. Provide a battle escort force for Battle Squadron
2. Provide TF command components for concentrated Escort squadrons
3. Be prepared to adopt primary subsector protection role on BatRon attachment to IN or multi-Sub-sector TF
If you play around with what you want each of the elements to actually do, starting off with a big list of what needs to be done then prioritising it and working out which bits can be done by what (hey, this can be done by DEs, we don't need BBs for it at all!...) then some of what needs to be worked out just drops into place.
