More than would be required to shuttle the crews to a suitably remote location on a nearby habitable planet.
Except the crews are already off the ships, the timeline for Raging Justice is already a few months behind what the latest book set it to.
And the SLN is already committed to both (not) sending additional superdreadnoughts into action, and sending battlecruisers on raids. Even if those Solly BC's have the similar crews to the latest Haven Sector podnoughts it's still going to be relatively small groups at a time, compared to Filareta's Folly.
