USS Excalibur

Specifications - USS Excalibur


Before the Concorde had even been formally approved Starfleet already realized some of its problems, while it had proven incredibly capable in both combat and exploratory operations it would likely face significant problems if engaged with a foe without support vessels due to a lack of offensive weapon systems beyond the fighters carried. Furthermore, with only limited production facilities any fighters lost in combat would be difficult to replace. With a return to deep space operations that could strongly benefit from fighters, these flaws were deemed unacceptable and development began of a new type of vessel that could carry an equal or only slightly lower amount of fighters without compromising on weapons systems and the general capabilities of other vessels. In essence what was envisioned as a complete platform capable of prolonged offensive and exploratory operations with little or even no support.

With this mandate the Corps of Engineers went to work on new designs, in this they were heavily inspired by the Akira Class which had shown itself as a very strong vessel with size being its primary issue and the Admiral Kuznetsov class Aircraft Carrier of the 20th century Earth’s Soviet Union which carried a significant amount of aircraft while preserving more traditional offensive capabilities.

After a year the initial design had been completed, the Ascension Class was to be a carrier with weapons systems dwarfing even the strongest foes while being able to carry the same amount of fighters as the Concorde. Additionally, facilities were included for replacement fighters to be produced if the ship were to be cut off from reinforcements for a prolonged period. With the ship capable to fight off foes with its more basic systems the decision was also made to dedicate significant parts of the aft section to flight operations so that in combat the ship could serve as cover while the fighters deploy from the primary hangar bay. Designers chose to go with a large single hangar rather than multiple smaller ones intentionally to allow for greater customization depending on the needs of the mission and greater emergency capacity. A much smaller secondary shuttlebay remains primarily for shuttles and runabouts while being capable of limited fighter operations as a measure of last resort.

The first vessel, the USS Ascension, was completed in 2386 and exceeded the expectations of many as it managed to defeat the Sovereign and Concorde classes in different trials with only a coordinated force of a Concorde with several capital support vessels being capable of defeating it. While not as fast in exploration as the Concorde had shown in trials it nevertheless defied expectations. In 2387 the class was officially approved and entered production with plans of at least 10 ships to be completed by 2395.
