Re: A (hopefully) interesting fanfic discussion topic!
If it was TOS era-ish (2250s-60s), I would think that an Archer-Class ship (the 50m long scout from Vanguard) would be assigned to the region. It's outwith Federation space and Starfleet jurisdiction, but seeing as how there out be UFP citizens heading out there, I would think that the Fleet would want to make sure they were alright--whilst also scouting out the immediate area as well, as a site for possible future exploration.
A small ship like an Archer would make sense to me. But then again, I love small ships.
