We also gotta remember, Star Trek is almost always focuses on the big ships. Enterprise, Voyager, Cerritos, they are all important, but I highly doubt the federation needs to deal with a major galactic event every other Tuesday. I doubt the USS Luna had as much adventure as the TItan. Most are standard surveying ships, like a Steamrunner with a crew of 24.
If they did, the Federation does a shockingly good job.
