Well, the implication is 4 extra shuttles, but given the Miranda went for them too and it's likely to make a big part of any task group it's just a rather small drop in any bucket (assuming 1x Fed with a shuttlebay and 4x Miranda with equivalent sized ones you'd be looking 40 shuttles, and with a cargo Fed and the same number of Miranda 36).
Quite, and something that (if Starfleet were willing to) could also help with provisioning somewhat during wartime (by an explicit word of god), though at the cost of about half the usable volume of the cargo bay.
I don't think we're quite at TNG era tractors where a ship can pull thousands or tens of thousands of times its mass with a beam, but that should be doable, especially if they've been cut up during battle.
Thanks, that clears quite a bit up.
