Far and away the most well known WarShip, the McKenna battleship has served for over 400 years as a symbol of martial power and prowess. The class was designed and introduced by Blue Nose Clipperships of Mars in 2652 and quickly became the pride of the fleet, winning two Martial Olympiads in a row (in 2696 and 2700) and considered by many to be the highlight of their military service. An astounding 280 McKennas, nearly two per year, were put into service before the fall of the Star League, but by the time General Aleksandr Kerensky left on the Exodus only 18 remained to leave with him. Carrying the heaviest arsenal ever mounted on a WarShip and some of the heaviest armor of the time, this time-tested battleship would only begin to be outclassed in the late 3050s.[3]


In the forward arcs the McKenna carries primarily Naval Autocannons and Lasers of the largest order, able to smash almost any other vessel in a single strike. Several AR-10 Capital Missile tubes, capable of launching any type of missile available, dot the surface of the McKenna and give the ship the armor piercing power necessary to face off with other Battleships and heavy Cruisers. The broadsides are where the real firepower lies, with 24 Heavy Naval PPCs on each side. Able to strike targets hundreds of kilometers away with extreme precision, they are split into groups of four to help concentrate their firepower against enemies. The aft quarters are similarly armed and directly aft are additional NAC/40's, NL55's, and AR-10's to deter pursuit and flanking maneuvers.[3]

Six docking collars provide the McKenna with an integral, dedicated DropShip escort. These small craft are backed by a full wing of 50 aerospace fighters. The ship carries no small-caliber close-in weaponry. This reflects the prevailing design philosophy of the period, in which such secondary armament was considered irrelevant to the battleship's chief role in ship-to-ship engagements and larger fleet actions. The "McKennas" relied instead on their fighters and small craft to defend the fleet from threats posed by small, maneuvering targets.[3]
