Akagi II Class XIV Heavy Carrier

Originally intended as an expanded Excelsior class vessel, the Akagi II was reclassified in 2287 shortly after construction had begun. Star Fleet procurement had completed studies of current Carrier designs and felt that the anticipated Trans-warp capability would exceed design tolerances for most current ship hulls. The eventual failure of Trans-warp did not deter designers who eventually finished stress tolerance evaluation of the Akagi, As the Excelsior was eventually adopted into the Federation inventory, designers mounted the experimental FWJ warp system onto the Akagi frame. The decision would have far reaching success when planner request not one, but two main redundant impulse system be installed. The Akagi became one of the first vessels to mount multiple independent impulse drives. A total of 6 separate impulse drives were installed, giving the Akagi unprecedented power survivability. The multiple engines also created significant problems for the design. In early 2288, several impulse configurations were considered, but eventually, the decision to use the well established FID-3 was made. Nearly every other impulse drive created subspace field problems that could not be overcome, and the Akagi her self was nearly lost during tests of various configurations.

While the combined impulse drives provided no more power than other impulse drive configurations, the Akagi class could easily power each of it main weapons from a different impulse engine, alleviating power restrictions on the main warp plasma system. The extensive cost of the multiple impulse drive required designer to create a combat package that marked the Akagi class as a moderate combat platform. The Akagi’s powerful phasers did not have the extended targeting range of other heavy combat vessels, but required fewer internal support systems and less maintenance. In most cases, the Mk I, finally launched in late 2289, was more than a match for comparable Klingon or Romulan cruisers, and could engage multiple enemy cruisers if called upon. The Akagi also maintained two separate internal workshops designed to help repair, modify and recover both shuttles and probes. This capability made the Akagi a popular support cruiser near hostile boarders where it was enlisted to recover probes and listening equipment left by scouting units. The Akagi’s could quickly recover these probes using specially modified shuttles and refurbish them for use by follow-up units. Because of this ability, five of the six Mk Is were eventually transferred from the Romulan/Gorn boarder to exploration duty along the frontier.

Eventually, as greater danger became apparent along the Frontier boarders, and increased tension with the Romulans became a concern, the Akagi was updated to the Mk II variant in 2301. Planners felt that the vessels needed additional firepower to compete with better equipped Romulan designs. The unique impulse system continued to serve the Akagi well despite newer and more powerful carrier designs. Even the updating of older carrier designs did not daunt proponents who secured funding for the construction of three more Akagi’s and the upgrading of all six MK Is. The Mk II would continue to serve for over 40 years until 2343 when the decision was finally made to retire the venerable carrier. In January of 2350, the last Akagi class carrier was decommissioned.

In 2373, all eight remianing Akagi’s were reactivated due to Doinion threat. Most were used as escorts during the conflict, with several seeing extensive combat action. Despite repeated engagements, none were lost during the conflict. However, the Akagi and Bataan were both damaged severely and eventually scrapped. The remaining carriers are now in reserve status pending upgrade or disposal.

The Akagi II were built at the Alpha Centauri VII and Sol VI shipyards.
