from the "Plausibility" of the chapters near or passing through the gothic sector, to the TT rules.
personally however, I am under the impression the UM, IF, BA, DA, SW, are the few remaining chapters still stocked well enough with Space Marine ships like Battle Barges, and Strike Cruisers, most other chapters lost their great warships in too great numbers to be represented fully.
totally false. we don't know the precise fleet count of many chapters, but we do know the fleet count for Blood Angels, Ultramarines, Dark Angels, Space Wolves, and Grey Knights.
before I go further, I'm gonna note that space marine chapters are generally divided into two lose types. Fleet Based chapters, that have no real home world, and are based off their fleet. (example: Dark Angels, Imperial fists, Black Templars, Blood Ravens, just to name a few) and "Domain based chapters" that posess a homeworld (Ultramarines, Blood Angels, Space Wolves, Grey Knights would also fit there) fleet based chapters are noted as having larger fleets then domain based chapters.
so, how are the fleet sizes?
let's look at them..
Grey Knights: 4 Battle Barges, 12 strike Cruisers, 8 Rapid Strike Vessels (the offical name for SM escorts)
Ultramarines: 3 Battle Barges, 8 Strike Cruisers, 12 Rapid Strike Vessels (it's worth noting Ultramar maintains it's own defence fleet as well. we can't be sure how big it is but it's proably a few lunar class cruisers or something)
Dark Angels: 8 Battle Barges, 16 Strike Cruisers, 21 rapid strike vessels
Blood Angels: 2 Battle Barges, 7 Strike Cruisers, 16 rapid strike vessels
Space Wolves: 8 battle Barges, 30+ Strike Cruisers, 40+ rapid strike vessel Squadrons (don't think too hard about the logistics of how they'd maintain a fleet of this size with a single feral world as their holding)
ignoring the space wolves as an outlier, it would seem that domain based space marine chapters likely average just under a dozen capital ships, with a chapter with 9 or less capital ships likely being "somewhat under supplied" from a transport sense (they ideally need a transport for each company after all) fleet absed chapters proably have double the average, and the dark angels numbers bear this out
