The WARHAMMER CLASS is a versatile federation runabout.
These are the Ferrari's of the Runabouts. They are equipped with small a conference/dining area, and even small quarters for resting on long journeys.
It incorporates integral nacelles, much like the DEFIANT CLASS.
The impulse engines have been modified to give extra speed at sublight speeds, so it is highly manouverable and fast in combat.
A unique feature of this vessel is its ability to traverse sub-aquatic environments. Even more unique is the experimental Fusion-Prop (FUPRO) drive located at the rear. This is essentially a propellor-driven form of propulsion, which can be activated if travelling at extreme depths where sub-thrusters become useless. Thus, this craft can go deeper than almost any existing space-faring vessel. When in sub-aquatic mode, 2 stabilizer fins are extended from the front of the ship, giving it superb manouverability underwater as well.
In short, this is an awesome support craft to have stashed in your hanger decks, and at least one WARHAMMER CLASS Runabout is currently being assigned to the hangars of newly produced starships (that are large enough to accomodate them).
Some carriers have whole squadrons of WARHAMMER CLASS runabouts in their bays, as do various space stations and research bases.
This craft is capable of a planetary & sub-aqua landings, and is equipped with Space/AquaSuits for unhospitable atmospheres.
