The Halberd-class destroyer (hull classification symbol: DD) is a well-armed warship model that has been used by the UNSC throughout the Human-Covenant War. Brought into service to phase out the ad hocGorgon-type destroyers, the Halberd is a modular starship that's designed to put down any civil wars it participates in any condition. These destroyers have become a favourite of many UNSC captains, being considered the most powerful and balanced warship of it's type ever to be manufactured. As the first destroyer to be fitted with two Magnetic Accelerator Cannons, the Halberd is capable of delivering unavoidable destruction even at long range, and it's unusually-thick hull allows it to easily brush off the firepower from any destroyer before it. This does not mean it's slow however, as it's equipped with a powerful set of fusion drives which ensures it's capable of chasing down Insurrectionist vessels before they can jump to safety.
The Halberd-class destroyer was first introduced in 2517, when SinoViet Heavy Machinery won the contract to manufacture the UNSC's next-generation fleet of destroyers. Operating in rapid-response units led by the Marathon-class heavy cruiser, they would quickly become synonymous with the UNSC's military might. Once the Covenant began their genocide against humanity, the Halberd would become one of the UNSC's most abundant defender, their arrowhead silhouette becoming an icon of the Human-Covenant War. Despite their solid construction and capabilities, the sheer technological superiority of Covenant weaponry led to these ships suffering some of the highest casualties of all vessels used by the UNSC Navy. Very few Halberds would survive the war, and while they continued to serve, they would largely be supplemented and replaced by the Strident-class light destroyer.
"My team weren't designing a ship; we were designing the future of the UNSC."
―Dr. Johannes Rafferty, during a press release.
The origins of the UNSC's most successful line of destroyers lies in 2511. The UNSC Gorgon had proven time and time again to be a game-changer in naval operations, displaying a level of versatility and reliability that no other ship has ever exhibited before. Despite this, the Gorgon was not without it's issues. It's design borrowed heavily from the old Hillsborough-class heavy destroyer, which as proven by the lead ship's experiences against the Bellicose, was not manoeuvrable enough to effectively utilise it's MAC against smaller threats. As a result, the UNSC recognised that an original-new design was needed in order to spread the MAC technology across their fleet of frigates and destroyers. Seeing their previous endeavour had resulted in the adaptable Charon-class frigate, the UNSC released another competition for a well-armoured destroyer equipped with two MACs. It was required for all designs entered to be a generalist ship that's effective against targets of all sizes and is capable of participating in escort and assault operations. They also stressed that the new ship had to be cheap and require a small amount of manpower to operate.
The final conceptual sketch of the destroyer.
As expected, SinoViet Heavy Engineering would jump on this competition, placing Doctor Johannes Rafferty in charge of the development of the new destroyer. Although not the oldest or most experienced person within SinoViet's design division, Rafferty held a reliable history with his most recent success being the Orion-class assault carrier. However, he was forced to work with up-and-coming engineers he had never worked with before, as Rafferty's previous team were reassigned to other projects or lobbied for heightened influence in the corporation. As a result, Rafferty's team was directionless and divided, taking different paths on how the final product should look and perform. These issues would be seen throughout all of 2511, although fortunately he had enough experience with the strengths and weaknesses of those below him. This meant that once he decided on the final specifications and design brief, he divided up the work based on how it suited each of his subordinates' skill sets.
Development would not finish up until 2514, with the last section being finished up is the very front. This portion changed from the characteristic pylon from the standard frigate to a far better-protected arrowhead structure that would become iconic with the class. With the blueprint finalised by Rafferty, the plans were handed over to the primary SinoViet manufacturing facilities above Reach for fabrication. The prototypes were constructed under the careful watch of Senior Engineer Cosima Daniell, and none of the upcoming ships suffered any delays during it's construction.
The original prototype christened the Halberd was launched from it's drydock on July 28th, 2515, and was sent to the UNSC Navy for evaluation. The evaluators discovered that the submitted Halberd-class was not only cheap and easy to man, but it was an effective warship by itself. These qualities saw the UNSC Navy contracting SinoViet to produce 1,340 destroyers to bolster their fleet.
An annotated layout of the Halberd-class destroyer.
Stockier yet somehow more compact to many other light-tonnage ships after it's introduction, the Halberd-class' hull structure has more in common with larger ships. It's sloped bow, for example, is clearly reminiscent of the Orion-class assault carrier, while it's lack of conformity to a stripped-down design is born from larger cruisers. This maximises it's reactor volume and increases it's structural integrity at the cost of additional mass. In fact, this focus on protection permeates through the entire destroyer's design; while it does have some obvious design oversights such as the vulnerable position of it's bridge and hangar, it's missile silos, engines, escape pods and crew segments are all hidden behind protruding slabs of armour. This makes them less vulnerable at most angles and means that certain sections can be protected with a minimal change in the destroyer's course.
At the very front of the Halberd is it's primary communications and sensory equipment. Containing a variety of antennae and lens for identifying and processing information at various ranges, these are obvious targets and vulnerable; as a result, most of this equipment is able to be retracted into the hull during close combat, only emerging for calibrating targeting solutions or after the threat has left. Just above this and still on the forward 'face' are the two barrels for it's MAC battery. Interestingly, it is possible to tell which block a particular ship is from, as the organisation can either have the two MACs placed horizontally or stacked on top of each other, with even the barrel tips being different from block-to-block. As these are key to the majority of the Halberd's firepower, massive slabs of Titanium-A battleplate line the bow's sides and top. The bottom is reinforced, but this is covered over with state-of-the-art gravity generators which are capable of de-accelerating dropships and fighters from astonishing speeds. Taking over the bottom half of the bow is a modestly-sized is a large hangar which holds two pelican dropships. A tactical operations centre is fitted within the centre of the hangar segment, with a battle network relay mounted on the bottom that assists in the coordination of planetside assets. The end of the hangar merges directly into the well-armoured Marine barracks, which includes everything from their cryobays and recreational areas to live-fire ranges and simulation pods for pilots.
The bridge of a Halberd-class.
Sitting at the very top of the destroyer is the main command bridge. The bridge is arranged in a u-shape, with a recessed centre floor segment which has either a holotable or command chair, depending on the captain's preference. Each of the monitors on the ceiling are dedicated to monitoring broad statistics of the ship's performance, with specific reports capable of being beamed to the commander's neural interface for private reading.
Unlike frigates and corvettes, the Halberd-class destroyer is intended for one purpose only; combat. This is reflected in it's deployment, where it's generalised well-rounded weapons outfit are effective against both large warships and agile fighter-craft. This makes it useful as a workhorse combat vessel, where it excels in groups; this can be either in escort duties where it would screen fighters, gunboats and missiles approaching the carriers, acting as the ship-of-the-line in large fleets and even leading frigates in rapid-response flotillas. In these instances, the Halberd will usually attempt to close the distance to make itself a more frustrating target, drawing the fire away from the fragile frigates and valuable capital ships. Unfortunately, this does mean that it cannot pursue it's own individual objectives without support, as it is too small to single-handedly route a group of warships by itself.
In the standard configuration, the Halberd's only real contribution outside of combat duties is medium-range reconnaissance, as it lacks much in the way of endurance. Fortunately, it's superstructure is modular and can be easily reconfigured at a large-enough drydock to meet the needs of specific jobs. It can be outfitted with the likes of larger cargo-bays for replenishing the consumables of stations and assault groups, or be equipped with more advanced sensors for searching for hostiles in contested systems. As seen on the UNSC Endeavour, extensive retrofits can allow them to carry a substantial ground force, although this is an unpopular choice and has largely been reserved for the thirteen specialist ships built above Chi Rho.

Propulsion and Powerplant
The aft of the Halberd.
As with nearly every other starship released during the Insurrection, the Halberd-class destroyer is primarily propelled by four large fusion drives and the four flanking secondary exhausts, with actual power provided by two identically-impressive fusion reactors. These two systems easily meet the energy requirements necessary to run the destroyer's systems and propel it through space, so much that it leaves many comparable vessels in the dust. Both of these systems rely on fusing Deuterium fuel in a reaction mass, but for different means; whereas the reactors fuse and break apart to solely generate usable energy, the drives use the immense forces present to fire out propellants at extremely-high velocities.
The twin reactors are both purpose-built V5/Medium-grade Deuterium fusion reactors, abbreviated to V5/M-DFR. Manufactured by the SinoViet-owned subsidiary Naoto Technologies, these reactors are designed for high performance over fuel efficiency. They are designed with four individual sphere chambers with a fifth located in the middle of this cage, each being self-contained with their own supply of Deuterium but are usually opened up to each other to increase efficiency. While this setup is unable to match the power or efficiency of a reactor with only a single chamber, it increases the rate they can shift their output, minimising the period in which the destroyer is vulnerable to ambushes. In theory it's also much more resilient in combat, which is unfortunately offset by Naoto's decision to leave the safety features and ceramic thickness to a minimum.
