Hyperion-class destroyer

"They're the perfect wolfpack ship - fast enough to keep up with scouting corvettes, modular enough to quickly respond to new threats, and deadly enough to overwhelm any enemy they encounter."

- Anonymous UNSC crewman.

The Hyperion-class destroyer (hull classification symbol: DD), colloquially dubbed the pocket destroyer by sailors because of its small size, is a next-generation destroyer utilized by the UNSC Navy in the last decade of the Human-Covenant War. Introduced as a cheaper, more effective warship to relieve the UNSC's aging fleet, the Hyperion is a response to the combat data of its' immediate predecessor, the. While it is true they are not as durable and lack some of the endurance displayed by previous destroyers, they make up for this with a modular design that allows them to be quickly refitted to counter new threats, a far smaller target profile, more advanced defensive subsystems, and enhanced armaments.

Key to the Hyperion 's success lies mainly in two fields; its size and larger-than-average fusion reactors. By shedding off some of the armor and redundant superstructure of its predecessor, the Hyperion is able to reduce its weight by nearly four hundred thousand tons and correspondingly reduce its target profile. This already increases its speed by a large margin, which is further enhanced by three massive fusion reactors. These allow it to support not only more powerful propulsion systems, but also allow it to utilize more MACs than previously thought possible. These two strengths ensured that a battle group of Hyperions could evade more shots and dish out more damage at range than even larger ships.

First commissioned in 2541, the Hyperion would see some early action in 2546, yet issues with its streamlined supports and power output would limit production until after 2553. Constructed alongside other 'frankenships,' they would serve in only a number of campaigns centered around human colonies due to their small numbers. However, continued development would see the Hyperion reach and surpass all areas of the Halberd. Even as they took over from the most elderly ships in the UNSC fleet, they would only exceed the annual production of their predecessor by 2556.

Origins
When the Human-Covenant War erupted first, the entirety of the UNSC was held in a state of shock. After centuries of searching, humanity's discovery that the first advanced sapient life they encountered was determined to see them destroyed put them on the back foot. This was best cemented during the first decade of the war; disregarding Vice Admiral Cole's campaigns, the took an unprecedented stretch of losses which forced them only to make stands at key colonies. The Covenant's ingenious invasion strategy, which often resulted in a number of colonies and habitats being attacked at the same time, was the main reason for this. However, their sheer technological superiority and unfamiliarity of their ships meant that once engaged there was very little chance for the UNSC to finish the battle without taking severe losses. These engagements meant that many fleeing ships would be picked off long before they arrived at their designated rally point, with even entire fleets being lost when they underestimated Covenant fleet numbers.

Eventually, within the decade the UNSC admiralty was forced to accept that they were facing a threat to their very existence. While all other branches of the UNSC began to address ways aimed at increasing their effectiveness, the UNSC Navy was seen as being extremely passive when adopting new technologies and armaments. Either out of habit or continual downplay of the Covenant threat, the Navy continued their doctrine of quantity over quality, with only their tactics and strategies actively changing. This encouraged their suppliers to make incremental improvements with some fleet-wide refits, or in the case of SinoViet's products even cutting out entire subsystems to deliver them sooner. This is in spite of studies consistently arguing that all existing ship classes, especially those which predate the Insurrection such as the Charon-class light frigate, required a minimum of three ships to beat their Covenant equivalents. The Admiralty's preference not to adopt more expensive replacements meant that the bulk of the fleet was made up of the exact same ships throughout the entire war.

Not all of this was the Admiralty's fault, however. Despite the risk to their very existence, many shipbuilding corporations were reluctant to offer replacements for their very successful products, believing that in time the Navy would learn how to best deploy their ships to offset their ineffectiveness. As this became less and less likely, they took to developing expensive starship designs, always drastically marking up their cost to keep existing classes of warships attractive in spite of the ever-worsening expected outcome of the war. Reports about how badly their ships are to their Covenant equivalents were carefully reworded to make them seem more reasonable; for example, Halberd-class destroyers were compared to Covenant frigates. Despite these measures, shareholders continued to grow less confident in the major suppliers' ability to offer a means to better protect them even as their revenue slowly grew, flocking to smaller companies eager to offer better alternatives. With the reality of smaller private entities wielding a disproportionate amount of influence on the company's decision-making making small steps closer, some of these companies began to seriously work on the development of successors - in the case of SinoViet, the pressure reached this point by at least 2535, when the design phase of the Hyperion-class began.

Role
As a modernised adaptation of the Halberd-class destroyer, the Hyperion-class destroyer inherits its intended use as a conventional ship of the line, supplementing the capital ships with its diverse range of weapons, protecting the carriers, and providing overwatch for the rest of its unit - a role they share with frigates.
