Cruisers

Cruisers are the big, tough, go-anywhere, do-anything ships of Star Trek Online. Every variant of the NCC-1701 has been a cruiser; pictured is my personal starship, the U.S.S. Paladin. Ain't she a beaut?

Cruisers can take an enormous amount of damage without batting an eye and then dish it right back out. They are dangerous from every direction, their large warp cores give them power to spare, and defeating a skilled Cruiser captain will often take concentrated effort from multiple opposing ships over an extended period of time--and if you don't put forth that effort and focus on other targets instead, they'll transfer power and send engineering teams to their allies, keeping a whole task force afloat.
