Triton-class destroyer

"Tough ol' girl's got some life in her yet."

- Captain John Bradley, commander of the HMS Watchman, during the Battle of Acheron

The Triton-class Heavy Destroyer was a heavy warship class in service with the Allegiance Navy during the Swarm War. it was the staple of the Allegiance's naval anti-armour capabilities as well as a fast and powerful warship. Introduced in 2685, the class was a leap forward in terms of ship design, the class influenced the design for every Allegiance warship for the next two hundred years as well as helping to establish Allegiance Naval power. The pinnacle of design and technology at the time of her conception, the Triton-class served with distinction for over two hundred years from the very first to the very last battle.

Role
The Triton-class was designed by Frasier Fleet Industries to fill the role of a fast, mobile ship-destroyer. it was capable of intercepting and destroying the majority of enemy warships. It had another role of supporting larger warships in battle, such as the Ares-class Battleship and Athena-class Cruiser. Its primarily offensive armament gave it a high kill/death ratio against other warships, specifically smaller ones such as frigates. It was able to receive a large amount of punishment thanks to powerful shields and thick armour, and provided a swift weapons platform for destroying enemy ships. It was capable of rivalling most ships in its class and also larger ships such as capital ships. All of these factors made it one of the most powerful Allegiance ships for her tonnage as well as a sought after command. Often these ships were accompanied by smaller vessels such as the Apollo-class Frigate and Aurora-class Light Frigate. It could also function as a rapid power projection platform, able to quickly deploy to trouble areas and subdue conflict with its presence, or at the very least, maintain the situation until the arrival of larger, more powerful vessels.

External Layout
Externally, the Triton-class was fairly standard for Allegiance ship design. She featured a long, narrow prow, supporting the main Heavy Particle Cannons. These were grouped into three groups of two, with cannons firing alternately. The prow was broken up into two sections, the larger upper one, housing four cannons, and the smaller lower one, with two cannons. Along this lower prow were six heavy missile tubes.

Aft of the prow, the ship was bulked out into the main hull. This section housed the vital ship's systems. Port and starboard of the main hull were two 'arms' which jutted out, and allowed space for the six Heavy ship cannons. The arms stretched aft and provided a platform for the sixteen Heavy Particle Cannon turrets, eight on each side, four above and four below.

Below these was the opening for the hangar, flanked on either side by the deployment bays. These provided shelter and protection for the exposed hangar. On the inside of these deployment sections were numerous hangars, containing Sabre Dropships or ground vehicles. Like all openings these were protected by powerful blast doors as well as energy shielding holding in the atmosphere.

To the rear of the vessel were the engines. These were mounted in two pillar-like formations and provided the immense thrust necessary to push the ship through space.

External bulkheads throughout the ship operated on failsafes and helped to keep the ship intact during heavy firefights.

Internal Layout
Inside the ship, the prow was mainly dominated by the Particle Cannons, their power capacitors and cooling systems. However, on the upper and lower prows where they met the main hull, were the majority of crew quarters.

Inside the main hull was the main ship systems and areas. The Bridge, or Command Centre, was one of the most important locations on the ship. From there, the commanding officer and command crew controlled the ship's functions, ranging from movement to weapons fire. It was situated right in the heart of the vessel, in the least vulnerable location. Situated throughout the ship were various smaller terminals from where the ship could be controlled, with the correct access codes.

Directly behind the bridge, though a few hundred meters further aft, was the main power core. Here, the Zero-Point energy used to fulfil the ship's immense power requirements was produced. The reactor was 123.8m across, 145.7m high, and took the form of a semi-spherical chamber with the core in the centre and struts forking symmetrically in.

The main cargo bay was located to the rear of the ship, holding large amounts of ammunition and supplies. The main ammunition store for the ship itself was located between the upper and lower prow, protected by thick armour plate and several metres of other ship functions.

The prow heavy cannons took up more than a third of the ship's overall length, with little else besides in that area. The cannons had an almost direct connection to the core, meaning that their charge-up time was drastically reduced. Special capacitors prevented the cannons from being overloaded by the core's massive energy outputs.

Main engineering was located immediately above the power core. Catwalks and access-ways from engineering allowed access to the core. If the core ever shut down, to do so would take 40 hours. Similarly, to start up the core again, a minimum of 24 hours would be needed.

To the rear of the Triton-class were the engines. These provided the thrust necessary for the Triton-class to out-manoeuvre hostile warships. Like the Particle Cannons, they were stopped form direct linkage with the power core only by a massive capacitor, which allowed the regulation of energy to the engines.

Forward of the engines were the barracks and vehicle housings. These could accommodate an entire Army or Marine company and their attached vehicular force.

To the port and starboard of the barracks were the 16 Light Particle Cannon turrets and their controls. These had an indirect link to the power core unlike most energy-intensive systems.

On the ventral side of the ship was an opening protected on either side by large structures. The opening was the hangar bay, a long deck with a drop bottom at the end. Inside the structures to the port and starboard of the hangar were various other support hangars. On the bottom surfaces of these were HALO orbital insertion pods for getting troops quickly onto the battlefield. There were two rows of six tubes in total, with three pods stored in each tube on magnetic retracting racks. When one pod was launched, another immediately slid down in its place.

Located throughout the ship were arms lockers which provided access to small arms. They were guarded by armed marines at all times.

Each door of the ship was automatic in opening, however could be opened manually if the situation needed. The doors were large and heavy metal ones and could withstand heavy small arms fire or explosive decompression. They could be manually shut from the door itself, from command terminals situated throughout the ship, or from the bridge, or by the shipboard AI upon the detection of decompression or advancing hostiles.

The main ship functions, such as navigation, targeting, and sensory data were controlled by independent AIs which had no purpose other than to perform their specialised function, for example firing every weapon mounted on the ship. The AIs were AIs in the broadest sense of the word, they were considered 'dumb' and were not able to learn anything beyond their area of function. The targeting, sensor and navigation controls were all operated by separate AIs, which essentially acted as advanced computer programs. Overseeing the entire ship was a smart AI which acted as an interface between the human crew and the ship.

The navigation, sensor and targeting systems all had independent sensor grids, although the primary sensor grid was much more advanced than the targeting or navigation grids. The 'nav' grid operated on long-range telemetry alone and could not be used as a short-range scanner. The targeting grid. picked up telemetry pertaining to enemy movements only and relayed this information to the targeting AI, which instructed the correct batteries to open fire. It detected long-range threats only with assistance from the Nav AI which would relay information about incoming threats to the targeting AI. The primary sensor grid picked up all data excluding targeting and long-range information pertaining to navigation. It was also responsible for communications.

The majority of the ship's interior was surprisingly spacious. Many of the corridors were wide enough to get more than five people past each other side by side. This meant that the ship was much less vulnerable to Swarm boarding parties than other, more cramped ships. Generally, once Swarm forces entered a ship, it was doomed, because the close confines of the ship were a natural setting for the hive-oriented Swarm, and perfect for savage melees and brutal ambushes.

Armament
The Triton-class Heavy Destroyer had a large armament geared towards defeating enemy cruisers and other warships. Mounted on the prow were six Strategic Instruments DDP-278 Linear Particle Cannons, powerful and long range anti-armour energy weapons. The cannons each had an individual output of 50,000,000 Terajoules, 23,100 times the power of standard MAC rounds and enough to destroy many ships with just a salvo or two. As for the rate of fire, power was not the issue, but rather cooling. The weapons, unlike MACs, were prone to overheating. A single cannon could fire seven times before needing to pause to cool, but it could pause at any time in between. After a full firing sequence, the cannon would remain inoperable for three minutes at least before the barrel was cool enough to allow another firing sequence. The group of six cannons were arranged in 'fire groups' of three groups of two, each cannon firing alternately. In this way, a fire group could fire 14 shots before needing to pause. The three groups could together fire 42 shots before needing to pause, although they could extend this by leaving slightly longer periods of time between each shot. They had a range of around 360,000,000km, or approximately 20 light minutes. The weapon's faster-than-light nature meant that they had no chance of missing their target, even over astronomical ranges. The Triton-class' heavy frontal armament was an excellent example of it being geared towards offensive actions.

On the port and starboard bows each were two rows of four turrets, 16 in all. These were MG9 Heavy Particle Cannon turrets, designed to blast through ship battleplate in broadside and long range. They excelled in large fleet engagements where they beat larger but less numerous cannons, with the ability to fire on many more targets and suppress them. They fired in a fashion much like a semi-automatic weapon, one shot, then a period of 4 seconds to cool. The cannons were far less powerful than the main guns, though made up for this with their numbers. They had a power output of around 1,250,000 terajoules per blast, which was 40 times smaller than the main cannons. Their primary purpose was as heavy turreted weapons able to engage ships at both long and short range, especially those out of the main cannon's field of fire. The turrets were the primary engagement weapons after the internally-mounted stationary forward weaponry, and had two tracking modes. The first, precise, long-range tracking mode, the turrets could hit a target five meters wide at a range of four light minutes (107,925,285 kilometres). During close-range combat and fleet engagements, the turrets could rotate fully in under six seconds with their fast-tracking mode, able to hit the majority of slow and fast-moving vessels.

In addition, the ship's prow featured ten heavy missile tubes, firing a wide range of anti armour missiles, with the ability to launch tactical nuclear missiles, often DECIMATOR ACSMs or VINDICATOR ACSMs. This powerful but variable armament gave the Triton-class a unique and powerful weapon with short, medium and mid-long ranges.

The Triton-class' frontal armament was supported by 14 M119 Heavy Naval Cannons. These heavy 900mm cannons, although a widely outdated armament, contributed to the class' heavy frontal armament, and were especially useful for engaging armour once the Particle Cannons had defeated any shielding. They were a relatively short range weapon, still used alongside the Particle Cannons for their variability. The cannons could be loaded with several weapon types (from RAPID, HEPAB, APFSTDS, HPSDAP, HPHE, HEPA and HVS/AP-HE), while the variability of Particle Cannons was restricted to the power of the blast, which could be selected from anything up to 100%. As a result, the cannons could quickly be changed from anti armour rounds to high fragmentation proximity shells almost instantly, in order to suit the threat faced, whereas the prow Particle Cannons were nowhere near as adaptable.

Even still, there were still signs that the weapons, which had clearly seen more prominent days, were on the way out. The Triton-class was initially fitted with six 900mm cannons on the sides of the ship, three on each side. However, later models, from around 2730 onwards, replaced these with modified MG9 Heavy Particle Cannons, in non-movable mounts, with their range extended by 30% to allow adequate frontal usage. Earlier ship classes had featured these 900mm cannons in large turrets as their primary turreted antiship armament, however these were largely phased out for the MG9 in the mid-2600s.

Bridging the gap between the larger MG9 turrets and the smaller M252 Point Defence turrets were 30 MD12 Particle Cannon turrets. These weapons were designed to complement the larger and smaller cannons, by supporting them in combat. They could act equally as point defence guns or as powerful anti armour weapons. They were roughly a third as powerful as the MG9 Cannon, though far more numerous and more effective at taking down smaller warships. They had a power of around 415,000 terajoules, and a range of about 50 million kilometres.

Providing a variable but powerful armament were 20 M125 Missile Launchers. The weapons were used as a versatile, powerful weapon able to engage multiple enemy types. Of the Triton's arsenal, these missile launchers were probably the most responsive and variable, able to be changed between high fragmentation antifighter missiles to long range antimatter missiles in a matter of seconds, in accordance with the ever-changing battlefield. They were utilised in two main roles; point defence, using precision or area-damaging missiles to defeat incoming fighters at short and short-medium ranges, and anti-armour, for engaging all smaller warships and many of the larger ones too. In the latter role, the turrets often employed the DECIMATOR Anti Capital Ship Missile, which could easily overpower a cruiser or carrier with thirty to forty hits.

The weapon consisted of an armoured box-like multi tube missile launcher mounted on a fast-tracking turret. Powerful but compact sensors specialised for picking out missile targets were located inside the ship, underneath the armour. To reload, the fully retractable turret would descend down into its stowage space below the vessel's armoured hull, where the empty missile box, acting similarly to a magazine, was swapped out for a fully loaded one. This dramatically increased loading times over more conventional methods and provided protection for the turret and explosive ammunition during their vulnerable reloading cycle. Typically a turret could go from just having fired its last missile to having a full load in under 25 seconds. Inside the ship, there were different types of 'boxes' holding different missiles. These were selected according to the type of enemy the turret was tasked with engaging. The fire control room was located inside the vessel out of harm's way, but control could be transferred to a remote station inside the ship, or given over to an AI or dedicated weapon program which could select targets, fire the weapon and reload it independently.

Augmenting the Triton-class' power were 40 M252 Area/Point Defence Weapon Systems, which could engage starfighters and very quickly destroy them. They offered both point and area defence against starfighters and incoming projectiles, and proved highly effective against larger targets in numbers, such as frigates, destroyers and some cruisers. The weapons were comprised of three DX52 Particle Cannons, arranged in a triple battery. The weapon had a range of 4 million kilometres, and a combined power of 7,500 terajoules, enough to tear through ship armour and vaporise starfighters.

In addition to these were 40 M253 Area/Point Defence Weapon Systems. These were fast-tracking armoured turrets mounting quadruple DP41 Light Particle Cannons. These were extremely effective against incoming ordnance, such as missiles and projectiles. As a secondary function they could engage and destroy fighters, but were not individually capable of posing a threat to vessels larger than frigates. They had a range of 250,000km, and a combined rate of fire of 5,200 shots per minute. Their combined power output was roughly half that of the M252, though in a continuous stream of shots instead of one large blast.

Weaknesses
As the Triton-class focused on large targets, naturally the smaller ones were overlooked. Although possessing a decent amount of anti-starfighter weaponry, the ship was still vulnerable to starfighters, particularly bombers and heavy fighters. This problem was exacerbated by the small starfighter complement the Triton-class itself possessed. The largest warships such as Heavy Cruisers and Battleships could generally outgun the Triton-class.

The ship's engines were highly exposed to enemy fire. These ships were also incapable of prolonged in-atmosphere operations unless the planet's gravitational strength was noticeably lower than that of Earth or Thera, mainly because the anti-grav engines would overload.

The ship had a small onboard ground force complement, meaning it could not mount large scale operations without support.

Shielding
The Triton-class gained shielding abilities from its the shield projectors, mounted at equal intervals along the ship's length. Powered directly from the core, the shields used up a phenomenal amount of energy- more than some planets.

Given that the shields of the Triton-class could withstand up to 3,500,000 Terajoules of energy per minute before falling, and a standard MAC round of the UNSC possessed approximately 21,580 Terajoules of energy, the shields of this vessel would be able to withstand 162 standard MAC rounds within a minute. Super MAC rounds deliver 21.6 zettajoules (21,600,000,000 Terajoules) of energy, meaning that the shields could withstand 0.000162 Super MAC rounds per minute. In other words, Super MAC rounds could utterly destroy the Triton-class with one round. Nevertheless, the shields were remarkably powerful and able to withstand huge bombardments.

The three shield generators could operate independently of each other, or in unison. This meant that even if one shield generator was taken offline, the two remaining ones could power the shields, if only at two thirds of full power.

The shields could stop projectiles entering the shields by them impacting on the surface, until the shield succumbed to the volume of fire. However, weapons could be fired from inside the shields without impacting on them.

Fighters could also not penetrate the shields, with the exception of Allegiance fighters. They emitted an encoded databurst to the ship's integrated AI, facilitating the dropping of the shield in a small area just big enough for the fighter's profile to slip through. This could be done by the AI within a few nanoseconds and prevented enemies getting a proper firing solution through the gap.

The shields could also offer protection from collisions with other stellar objects, although it put an immense strain on the shields and the Triton-class' structural integrity. If a vessel was rammed purposely during a battle, the chances are that it would not survive.

Armour
As the primary armour system used by the Triton-class, the vessel made use of an advanced new technology called ERA or Energy Regenerative Armour. ERA consisted of two layers of armour. The first was an energy-ablative, superconductive nanomaterial layer impregnated with electrical circuits. This layer effectively trapped almost all of the energy from enemy fire, whether that be kinetic, chemical or others. While not providing the perfect defence, its primary function was to feed this energy to the layer below. This was a variable property, energy reactive layer of extremely advanced nanomaterial whose properties changed when exposed to massive energy. In short, the armour became stronger when under fire. This extremely adaptable and useful ability stemmed largely from the Forerunners, who employed a similar technology in their Keyships, renowned for their ability to withstand concentrated, localised fire even without shielding. This technology was only successfully reverse-engineered in 2642.

The secondary layer relied upon the primary layer functioning efficiently for it to operate. As protection was only a secondary function for the primary layer of armour, it did not have an incredible resistance to enemy fire, leaving that to the lower levels. As a result, over time the effectiveness of the first and second layers decreased. The more damage the primary layer took, the less effective the second layer was. Eventually, after heavy and concentrated fire, the effectiveness of these layers was rendered nil. However, units armoured with ERA rarely exposed themselves to so much fire to allow this to happen, only rarely occurring in extended and intensive combat arenas. ERA was employed on all Allegiance warship designs from 2651 onwards. While its power requirements were easily met by the huge Zero-Point Generator the Triton-class relied upon for power, it also offered huge advantages when engaging in combat with other spacecraft. It could splinter MAC rounds, shrug off high explosive and armour piercing rounds and harmlessly absorb directed energy weapons. When antimatter and nuclear weapons were used against ERA, the resulting energy increased the impregnability of the armour by several hundred times. However, it was very occasionally possible to overload the armour by concentrated antimatter weapons or directed energy weapons of a colossal scale.

It was only ever used as an addition to more conventional armour technologies, for instance ACE Armour. As ERA was dependent on energy sources and was only effective with strong armour layers underneath, vehicles only capable of mounting ERA or ACE usually chose the latter for its low maintenance and reliability, not to mention its non-existant energy requirements.

Underneath these primary protective layers were more conventional armour materials, which, underneath the removable first two layers, were modular and easily replaced. They were part of an armour technology system called ACE Armour or Advanced Composite Endurance Armour.

The ACE Armour system was several layers of advanced materials, combining to form an incredibly resilient composite. It was capable of surviving devastating and extended hostile fire, and was equally effective against directed energy weapons, ballistics and explosive weapons. The Triton-class employed a modified version to allow it superior protection when facing enemies in naval combat. Fighters and other single ships were armoured with lesser amounts, though still able to take heavy damage before exposing the craft to danger. It also offered huge advantages when engaging in combat with other spacecraft. In large enough amounts, such as on te Triton-class, it could splinter MAC rounds, shrug off high explosive and armour piercing rounds and harmlessly absorb and dissipate directed energy weapons.

The first layer of the composite modular armour helped hold the outer armour together, and allowed some slight flexibility yet superior density to engage various threats. Resin-impregnated carbon nanotube fabric was wrapped around the composite armour to allow the best small arms protection and structural strength. Below the outer layer was the primary defense in the event the energy-ablative armour was penetrated; a single piece poured Ceramic DCP plate.

The Ceramic Plate was sandwiched between two plates of CVT (Chromium Vanadium Tungsten) and Austenitic Steel alloy. The whole assembly then underwent a triaxial-prestressing method in which the preformed, porous ceramic material was soaked in a bath of molten metal, resulting in super-dense material. As the metal cooled, the composite of three plates (one of ceramic, and two of alloy) compressed, increasing both the density and compressibility of the composite dramatically. This process worked at relatively low temperatures and therefore was more economical than most comparative methods. The resulting compound could be molded into complex shapes and offered improved protection at significantly lower weight. This by itself was rather effective but was only secondary to the ablative layers and was superseded by other armour layers beneath.

Below the outer plate were several overlapping Ceramic chevron-shaped panels. These chevrons forced any round that happened to penetrate the outer plate to then penetrate the chevrons at a much higher oblique angle than the outer plate. This increased the armour's effectiveness not only by changing the penetrator's vector, but by increasing the thickness it had to penetrate before reaching the interior and disrupting even tandem warheads and delayed timer high explosive rounds. These chevrons were suspended in an elasticised rubber-like polymer that reduced the shock to the overall plate and transferred much of the impact energy outwards, reducing the stresses on the impact plates and feeding the energy-reactive armour layers. This material also helped break up penetrating HEAT warheads and KE penetrators by causing the chevrons to move around under the force of impact, deforming it and degrading its overall performance. In addition, it provided a reliable defence against HESH rounds, which were still in utilised despite a decline in usage.

Backing the composite materials was a second composite Alloy/Ceramic plate forcing the penetrator to again punch its way through at a different vector, forcing the round to fold or break up before it can defeat the final plate. The whole composite was then sealed in a wrap of carbon nanotube fibres to absorb any remaining spall and attached to the non-modular, base armour of the Triton-class's hull in sections for easy replacement.

The underlying, non-modular base armour for the Triton-class was produced using a process in which sets of inexpensive, thermodynamically compatible ceramic powders (Boron Carbide and Titanium Carbide) were blended with thermoplastic polymer binders, then co-extruded to form a fibre. This fibre composite was first braided then woven into the shape of the desired component. The fabricated component was then stacked and pyrolyzed to remove the polymer binder and hot-pressed to obtain the base preformed ceramic material for final processing.

This preformed ceramic matrix was still somewhat porous, and, though it was extremely hard and rather ductile, it was still rather fragile. The preform was then soaked in a liquid metal alloy bath. The preform absorbed the liquid metal, which then reacted with the ceramic powder to form a new ceramic compound that filled in pore spaces. The result was a plate with a larger internal solid volume, but the exact same external shape and dimensions as the original preform. This method required reaction temperatures of only around 1,300°C, compared to the 2,000°C required for traditional methods to form high melting point covalently-bonded ceramics. Because the final plate maintained the shape of the original porous ceramic, the need for post-process reshaping was removed.

Following this, the material was condensed using gravitational field manipulation, achieving a 82% smaller material for the same weight. This meant that the material was much more usable and more resistant to enemy attacks. Kinetic and chemical weapons had absolutely no effect on the material. The finished composite was extremely dense, lightweight (comparable to a similar strength material) and was ductile enough to resist severe impact stress, while providing excellent thermal properties and being easy to manufacture and replace when installed in a modular system.

Afterwards, the material was softened, or in some cases (where then material was composed of few or no individual components) liquefied by ion fusers. Then, as the resulting alloy cooled, it was bombarded by charged-particle vibrating waves. This dramatically improved the bonding strength of the molecules and gave the armor incredible resiliency. This again contributed to the sheer impenetrability of ACE Armour.

Underneath this, the Triton-class also mounted an extra layer to allow it better survivability in spatial combat. This was a layer of Titanium carbide, impregnated with latticed neutronium filaments, a microscopic latticework of strands throughout the metal alloy. This was coupled with a layer of boron nitride, which could withstand almost any assault and protected the ship from dangerous radiation emitted from many celestial bodies, as well as the thermal energy generated from the ship’s re-entry into atmosphere. This final dual layer increased the structural integrity of the ship and allowed it to remain intact despite any heavy bombardments or gravitational forges that the ship may be exposed to. It also acted as the base armour of the vessel, its last line of defence before the hull was breached.

Engines
For sublight propulsion, the Triton-class employed a tandem engine layout. Standard ion thrusters were used to provide low sublight speeds, as well as sole propulsion in atmosphere. The drives provided a rapid acceleration, which made them useful for slower evasive actions and movement in atmospheric conditions. However, they had a relatively low top speed, of around 12,000kph.

The concept of Ion Drives was nothing new, and most spacefaring vessels employed a similar such system. Propellant gas was passed through an alternating electric field, ionising the gas. It was then expelled out of the engines at near the speed of light. The electric field used was massive in terms of power, meaning higher efficiency and less propellant gas needed. The colossal power for the field came from the near-limitless amounts of energy generated by the zero-point reactor.

For higher sublight speeds, the Triton-class utilised Graviton Drives, which, although were much slower accelerating than ion drives, had a hugely different top speed. Their top speed was near 20% the speed of light, though speeds of more than 5% were rarely used due to the associated relativistic effects. When going at higher speeds, the ion drives were used to quickly accelerate the ship to the drive's maximum speed, where the graviton drives took over for a slower acceleration and higher top speed.

These Graviton Drives used a much more advanced method of propulsion. Using graviton manipulation, they were able to slowly achieve unheard of speeds, though at the expense of fast acceleration.

The Triton-class also possessed numerous anti-gravity engines which allowed it to hover in-atmosphere. These engines were similar, though more advanced, to the ones employed by the Covenant, which were reverse-engineered from Forerunner engines. The ship was not designed for prolonged operations in atmosphere and was required to return to space for 6 hours for every 24 hours of operation. This was due to a design flaw that did not allow the engines to properly radiate excess thermal energy.

Complement
The Triton-class possessed a small onboard complement for its size, as it was not needed for the ship's primary functions. In spite of this, the ship carried a Marine or Army detachment of one Company, or 96 men. This was mainly for boarding parties and onboard defence, but, if the situation needed, all 96 men could be transported to a planet's surface for deployment.

The ship's deploying complement of 96 men was in addition to the 400 or so Marines whose purpose was to protect the ship itself from boarding. These troops were rarely if never used during planetary assault missions.

Providing close air support and troop movement were twelve ATL-772 Sabre Dropships. They were each capable of carrying a maximum of 16 personnel (twelve seated, four standing). To transport all of the troops down to a planet, each dropship would carry eight soldiers. The dropships were capable of transporting armoured units in atmosphere but not through re-entry, unless they were small enough to be stowed in the troop bay. To deploy larger units, the ship also possessed a single CT-40 Vanguard Heavy Transport, however this could not take every unit down to ground in one trip. The Triton-class would either get another vessel to mount a land offensive or simply enter atmosphere itself and deploy troops that way.

Providing the ship's fighter forces was a squadron of AL-56 Flashfighters. They were capable of both spatial and atmospheric operations, and with even numbers fared well against the Swarm fighters. Unfortunately, the Swarm mainly employed starfighters in massive numbers. From 2741 onwards, when all the Triton-class were refitted and updated, the number was increased to 24 starfighters (2 squadrons). As the Swarm War dragged on, some ships replaced their Flashfighters for newer fighters such as the AL-61 Valiant Interceptor and F-307 Blackbird as the older fighters were lost in combat. However, some Triton-classes kept their original starfighter classes as replacements for the lost fighters.

Construction
Triton-class Heavy Destroyers generally took between seven and nine months to complete at the Allegiance's primarily-automated shipyards, according to availability of components. With all components present and labour-intensive building, the ship could be built in four months, though placing a great strain on other projects in need of un-automated workers.

The ship was the fastest ship build for its tonnage due to its simple design and construction. It could be built in half the time of a Hera-class Carrier, but Apollo-class Frigates were smaller and cheaper and therefore were constructed quicker.

Operational History


The Triton-class was first introduced in 2685, after years of planning and building prototypes. The first ship, HMS Triton, was completed on 22nd August, 2685. At the conclusion of the Swarm War in 2878, some ships of the class were nearing 200 years of service.

These ships, making up the staple of the Allegiance's anti-armour capabilities in space, and supported by large but less numerous ships such as the Ares, Hera and Athena-class, saw combat during every major battle during the Swarm War. They generally fared badly against the Swarm, which employed swarming tactics with starfighters, something the Triton-class was vulnerable to. By 2741 all Triton-classes had their starfighter complement increased to 2 squadrons of Flashfighters and an increased number of point-defence and CIWS, lessening but not eliminating the class' weakness to large volumes of starfighters.

The class saw action during the first battle of the Swarm War, the Battle of the Antaeus Nebula. It participated in virtually every battle during the Swarm War, including the Battle of Acheron and the Battle of Chiaras.

Battle of the Antaeus Nebula
This was the first battle of the Swarm was and a severe defeat for the outgunned Allegiance warships. The early stage of the battle proved the effectiveness of the Triton-class' devastating prow weaponry, but its severe weaknesses against hordes of fighters and bombers. The battle concluded with losses of two of three Triton-class Heavy Destroyers for the Allegiance and the loss of six of nine Swarm vessels.

Battle of Acheron
When the Swarm launched an assault on the Allegiance-held world of Acheron, the Allegiance Navy mustered all it could to aid in its defence. As a result, the Triton-class ships present were largely relegated to a support role, due to the large numbers of heavy warships, such as Athena-class Cruisers, Ares-class Battleships and Hera-class Carriers. However, this did not impact on their performance, and they still accounted for more kills than any other class. They were defended from the Swarm starfighters by a defensive screen of Apollo-class Frigates and Artemis-class Patrol Ships, intercepting or holding back starfighters from engaging the more vulnerable warships. Both sides took heavy casualties but the Allegiance prevailed.

Battle of Chiaras
Six hundred and forty three Triton-class Heavy Destroyers took part in a massive thrust into the Swarm territory of Chiaras, designed to show the aggressors that the Allegiance was a foe not worth engaging. Swarm losses were total but Allegiance losses were greivous. For the first time, Allegiance ships were boarded by Swarm vessels, as soon as this happened, contact was lost. Such vessels were destroyed by the Allegiance after the engagement. Fewer than fifty Triton-class ships survived.

Refit
The class's first refit was in 2741-2, when the class was approximately 56 years old (despite production never having ceased). The class gained an expanded array of point defence weapons, upgrades to shields and sensors, and a heavily rearranged hangar allowing for 60% more capacity. All ships were subjected to a full systems and hull diagnostic- every inch of the ship was scanned in depth. This took roughly a month for each ship, after such time repairs were made. The hull's heat/energy-ablative surface was replenished to combat any erosion which may have occurred. The powerplant was also modernised and updated to higher standards.

The majority of individual ships have some other replacements, form barrels of energy weapons to bulkheads to wiring. The HMS Triton herself had her observation deck replaced. The class also had its hangar refitted to handle the extra dropships and starfighters. Continual refits throughout the decades ensured this old ship was never outclassed. The class was finally retired in 2892, fourteen years after the end of the Swarm War and two hundred and seven years after the first ship entered service.

Behind the Scenes
This ship was designed with a very human style in mind. It's supposed to be reminiscent of the UNSC ship designs with its prow heavy weaponry and vertical, column shape. It's also a bit like the USS Sulaco from Aliens. It's supposed to look like what humans would build ships like if they were as advanced as the Covenant. Basically, it's an advanced warship whilst still retaining typical human design characteristics.
