From 2056-2058 all of the Fleet's major combatants underwent a series of Mk II upgrade refits. The most important component of this upgrade series was the exchange of each ship's older Magneto-Plasma drives for the new, much more powerful Internal Confinement Fusion Drives. Pound for pound, the ICFD offers a 25% improvement in thrust over an equivalent Magplas drive. Each ship also received major upgrades in sensors and fire control. All military ships save the Akizuki now utilize Ceramic-Composite armor, and the Moray and Luna now feature shield generators as well.
The Mark II upgrade to the Akizuki-class missile boat utilizes a compact Longbow-series fire control system. The tonnage saved from this upgrade was used to add 5 additional box launchers.

The Mk II upgrade to the Broadsword-class corvette utlilizes more potent armor protection and upgraded sensors and fire controls. Enough tonnage was saved with these upgrades to increase the laser battery from 3 to 4. It is among the fastest of the Republic's large warships.

The Moray-class frigate benefited greatly from its Mk II upgrade. The improved fire control and sensor systems offer a 50% improvement in range for half the weight of previous models. Armor protection has been slightly improved for less overall weight. An array of shield generators provide a further layer of protection. The Mk II upgrade also adds a trio of 10cm railguns.
Most importantly, the improved "Flash" anti-missile missiles represent a vast improvement over the anemic Dart AMMs.

The Luna-class destroyer is currently the largest fighting ship in use by the Fleet. Although some planners have argued over whether the Republic's largest combatant should be classified as a mere destroyer, Space Command has plans for much larger ships in the future.
The Mk II variant of the Luna is considerably stronger than the original version. Armor protection has been increased by 25% for less overall weight, and five shield generators were added as well. The 10cm railguns have been replaced with 12cm railguns, which offer the same rate of fire but with longer range and more damage potential. The Luna uses the same common pool of upgraded sensors and electronics that are in use throughout the Fleet.

The Red Oak Victory-class Fleet Support Vessels are technically not warships, although they are built to military standards. Still, this class has provided vital service during several extended naval operations. The Mk II upgrade features enhanced ICFD engines, but all other systems remain the same. While moderately armored, this vessel should avoid combat because its large magazines are vulnerable to shock damage.
The onboard hangar bays are primarily intended for reloading Akizuki-class missile boats in the field. However, because the Republic currently lacks dedicated carriers, on several occasions these ships have been used to deploy Starhawk squadrons.
