Federation Aircraft Carrier

The Federation Aircraft Carrier is the defacto flagship of the United Federation of Nations' 5th naval fleet and by extension, the flagship of The Order of the Black Knights.

Design and Specifications
The Federation Aircraft Carrier unlike the ones used by Britannia which were all Carrier-Battleships, is true, full-blown aircraft carrier in the literal sense.

As such, it was capable of launching and housing more aircraft and knightmare frames than any other type of carrier-battleships, at the expense of leaving the ship itself, grossly underarmed for its size. As such, the aircraft carrier is dependent on carrier battlegroups to defend it such as a small fleet of Federation Destroyers and Federation Cruisers.

Operation History
During the events of Code Geass: Lelouch of the Re;surrection, the UFN called in the 5th fleet to engage a campaign against the Kingdom of Zilkhstan to retrieve Nunnally vi Britannia from the clutches of Shamna. Due to the actions made by Lelouch beforehand which crippled the leadership structure of Zilkhstan, the Kingdom was unable to mount a proper defense, allowing the aircraft carrier along with its battlefleet to achieve air supriority and safely land its marines issue UFN control.

Trivia

 * The design of the aircraft carrier, although difficult due to the lack of screen time and awkward camera angles, seems almost like a carbon copy of the real world Nimitz-class Supercarriers.
