Description & Notes
Fleet Data: As the second of the Perimeter Defense Directive ships, the Steamrunner-class Heavy Frigate drew on the design elements of its bigger cousin, the Akira-class Heavy Cruiser. Like that ship, the Steamrunner uses an aft mounted rollbar-like structure, though in this case its pod holds the ship's deflector rather than its warp drive system. Like the Defiant and, Saber classes, the Steamrunner pulls its warp nacelles in, reducing their vulerability by dispensing with the standard nacelle-pylon configuration.
The Steamrunner-class was designed with a relatively specific set of mission profiles in mind. These include perimeter patrol & defense, long-range threat responce, covert operations, & combat support. To help fullfile the latter role, the Steamrunner, like the Akira, has a large through-saucer shuttlebay used to carry Starfleet attack fighters & other-small vessels into battle. Fighters leave through the two large shuttle doors on the forward side of the saucer, then circle back to the aft side to land when they ready to return.
With its size, powerful engines, & ofensive strength, the Steamrunner has proven itself a capable & durable combatant. Ships of this class played a major role on many battles durring the Dominion War.
