The Nova class,was a Science vessel designed for short range planetary research.(from Equinox) has a crew of 80.
Al thought compared to Voyager it seems like a weak very inferior vessel tactically according to Janeway it was able to survive a beating from Voyager.
so its clearly a tough little ship kinda like the Intrepid as well.
in Endgame a Nova class refit the Uss Rhode Island was able to distract 2 Neg'hvar class Battle cruisers and damage them,it also displayed high maneuverability.
