The Concorde class was a type of Federation command battlecruiser starship in Starfleet service in the early 25th century. The Concorde-class was one of three Starfleet command battlecruisers and had a counterpart in the Klingon Defense Force and the Romulan Republican Force, respectively. All of the command battlecruisers were tier 6 starships and required a commanding officer ranked vice admiral or higher. (STO video game: Delta Rising)
The Concorde class was designed by the Starfleet Corps of Engineers in 2410 and launched in the same year. The development project was a cooperative effort between the Alpha Quadrant Alliance members, which saw the production of a total of nine ship classes, three per member state. One class of each faction was geared towards engineering, tactical and science. The Concorde-class command battlecruiser was geared towards engineering, which was reflected in its bridge officer stations allocation.
The Concorde-class command cruiser was a tier 6 starship type and required a commanding officer ranked vice admiral or higher. The ship's crew complement topped at 750. The ship had four aft and fore weapon slots each. Standard equipment included phaser arrays and photon torpedo launchers but the ship was also able to mount dual cannons. During combat, the command battlecruiser would launch four Type-8 shuttlecraft from its single hangar bay. In addition, standard equipment of the Concorde-class starship included the fleet support platform, a mobile platform able to replenish deflector shields of the starship and nearby allies.
The bridge was staffed by one commanding officer, one tactical officer (lieutenant), one engineer (lieutenant commander), one lieutenant of any department, and one commander specializing in engineering and command division.
A new technology introduced with the command battlecruisers were inspiration abilities. During combat, the Concorde-class starship could inspire nearby allies with several abilities: turn the tide, against all odds, and battle preparation. Other enhancements of the class included absorptive and enhanced plating, enhanced weapon banks, armored hull and improved brace for impact. The command battlecruiser was equipped with a two-geared cruiser communications array, allowing for shield frequency modulation and the ability to attract fire. (STO video game: Delta Rising)
In the 25th century, the design of the Concorde-class command ship allowed its commanding officer to choose from different designs of livery, which could be modified further at starbases. These options were designated Type 1-5 and Veteran. (STO - The Klingon War mission: "Welcome to Earth Spacedock")
Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion. (STO missions: "Coliseum", "Cold Storage", "Boldly They Rode")
