Given that S2 won't be spending too much time on Gwyn's efforts to unify Solum (or at least, we were told this), I suspect that the Dauntless could be used to ferry her to Solum and wait nearby (doing other things) to see if her efforts are successful.
We were told S2 won't be spending too much time on Gwyn/Solum? When/where? AFAIK, the only thing we were told is that Keven Hageman confirmed (in a Youtube interview) we will follow Gwyn during S2, but no word on how much or how little time we would spend with her. Such details on S2 have not been released, I think. The only other thing we know is a hint from Jameela Jalil that Gwyn and Ascencia will develop a more complicated relationship (as opposed to the very clear hostility there is now).
I suspect the Voy-A will also have a form of advanced FTL propulsion technology that might rival QS... if not Quantum Slipstream itself... possibly even the Proto drive technology?
It would be a shame if a vessel named after Voyager did not have one of the "ludicrous speed" drives, given its predecessor was among the fastest ships of its time in Starfleet and it was known for its ultra-long voyage.
It was suggested that A ship might be sent through the wormhole to go rescue Chakotay and his crew... meaning that no other vessels besides VOY-A will go through the wormhole
Has that been suggested? There are hints the Voyager-A will be Janeway's ship or flagship (in the meaning of the vessel that has an admiral on board who is in command of a specific mission, or of a group of vessels like a task force or fleet) for S2 and that Dal and co will likely be on it. However, Dal's actor has stated they will be training along other Starfleet trainees, so we are likely looking at either a large vessel or a ship with a dedicated training mission, or both.
Moreover, Starfleet has classified the temporal rift under the temporal prime directive (see
) with it being implied that this may mean Janeway has no permission to go rescue Chakotay, at the time the log was recorded.
So, it seems more likely to me that the Voyager-A, if it is indeed quite full with various Starfleet trainees, will not be risked for this mission (which may even be undertaken clandestinly by Janeway, in the best Kirk-tradition) and they may use a shuttle/runabout/Delta Flyer/Defiant-class/Protostar-class instead. If Janeway goes in without or against orders, she will need volunteers who are loyal to her, and who better than her young protégés (and maybe a few others she trusts)? Especially since the show is supposed to be about them, rather than about those who already are proven within Starfleet.
It's possible the Voyager-A will go in, but in light of those considerations, I think it is more likely this vessel and its crew will not be risked. Especially since Janeway may have more than one vessel at her disposal (admirals usually do, the situation in S1B notwithstanding), and even if they go in small on a shuttle they could potentially make it out and back with the original Protostar prototype (if that is still on Solum, that is to say, if they arrive in the future at a point where Chakotay hadn't sent it back yet).
