My Take on Clan Sea Fox
The Khanates have seem to have their own territories, with the 'borders' of them being fairly porous to their neighbours. The ilKhanate can move wherever it likes, and probably is centred on the Republic of the Sphere territories and/or the Clan OZ's in order to capitalize on the most markets and to defend Twycross, Itabiana, and Trondheim.
Each nation has probably 1-3 enclaves, consisting of areas no bigger than a small continent (ie: Australia or smaller), in the various Inner Sphere States which they use for local manufacturing, spare parts for the Khanates, and raising of civilians and sibkos. After all, while being spacebourne has its advantages, it is ALWAYS better to spend SOME time on an actual world for the human body.
Each Khanate is organized similar to a Galaxy, with Aimag's taking the place of Clusters. As such, there is probably an average of 5 Aimags to each Khanate, each with the equivalent of 1 Cluster of troops on hand. Each of these Aimag's would probably form a Transport Binary, centred around the CargoShip of the Aimag. Alpha Aimag, the "Keshik" Aimag, would have an ArcShip flagship instead of the usual (presumably smaller) CargoShip.
Each Cluster attached to the Aimag would probably consist of 3 Binaries/Trinaries of Aerospace fighters and 2-3 Supernova's of Ground Forces. These are probably 1 Supernova of mechs/Battle armour, and one of armoured vehicles/Infantry.
As such, Clan Sea Fox PROBABLY has:
20 CargoShips
5 ArcShips
25 Clusters of Troops
Not bad for a group with only 3 planets of their own!
