Per WoR: the Stone Lions were preparing to activate the last two vessels in the Horses’ naval cache, the Cobras pulled three ships out of mothballs, the Sharks only had one vessel in their Vinton cache that worked (the rest were too heavily damaged by a passing comet) and managed to get one of two vessels in their Babylon cache activated, and the Adders’ cache was emptied out. No word on the rest.
It doesn’t ultimately matter, though, because even with just what all sides have on paper right now, the Home Clans vastly outnumber the Scorpions in WarShips (and in offensive ground forces, too, honestly). Despite the overly-rose-tinted-glasses some are using to view the Empire’s capabilities, they’d still be at a massive disadvantage in any sort of honest-to-goodness war with the Home Clans.
