Gettysburg class

The Gettysburg class heavy command cruisers were a type of starship on active duty in Starfleet during at least the late 23rd century. 

Similar in appearance to heavy cruisers, the Gettysburgs first appeared (in the Star Fleet Battles timeline) in 2286. The primary hull was an experimental design that was warp-capable. There was also a 20 percent increase in phaser firepower.

The standard crew complement of a Gettysburg was 388 plus 95 surface action specialists.
