Hull Composition:
Double layered semi-organic pliant self-regenerating 2nd Generation Bioskin covering a titanium double hull supported by a steel frame
- Flight 2 and 3 vessels fitted with 3rd Generation Bioskins

Bioskin details:
Anechoic, genetic hullskin developed as an acoustics countermeasure. The genetically-engineered material - a living organism by any other definition - covers the exterior of the hull as two layers, each approximately 3 and a half inches thick. Both layers are highly tensile, densely composed structures which absorb and distort active acoustic signals such as sonar pings, thereby drastically reducing the effectiveness of sonar equipment directed at the vessel.

Secondly, the bioskin attenuates sounds emitted from the submarine - especially from engine machinery. This substantially reduces the passive sonar visibility of the submarine, rendering it effectively completely stealth to passive detection at extended ranges.

Thirdly, the bioskin possesses self-regenerating properties that enable it to seal any external breaches to the pressure hull. Being a second-generation skin, the genetic properties allow a rate of regeneration which can completely seal a compromising hull-breach up to 30 feet wide in just less than 30 minutes, allowing the internal compartments to be isolated, sealed and then siphoned of water to allow extensive internal repairs to otherwise crippling damage without the need for a drydock or harbour facility.

The genetic composition of the hull skin is one of the most classified and tightly controlled secrets in the UEO Navy's bioengineering corps. The degree of effectiveness of the technology is unparalleled by any other navy in the world, and it is reported that the technology has helped in reducing the sonar signature of UEO submarines by up to 85 or 90 percent.

Computer Specifics
The IBM-VI is the 'standard' for small boat systems within the UEO. A fiber optic computer system, it is much faster than silicon processors, and shares many physical similarites to high-end civilian computers. The computer's primary advantage over civilian systems is found in its software - the IBM-VI cores aboard Trident class SSNs make use of a limited AI which radically aids in processor management and resource allocation, streamlining ship operations and allowing the crew to focus on other tasks rather than maintaining computer systems

The IBM-VI Fiber Optic core is considered a low-end computer in the military. They are relatively cheap and easy to maintain - one of the few advantages they have over the neural circuitry of next-generation systems found aboard larger, more advanced ships.

Later boats of the class have been built with the newer IBM type VII core; a smaller version of the type VI carried aboard the larger Defiance class cruisers. It offers faster processing speed, greater integrated systems management capability and better compatibility with current generation military networks.

Internal: Hypersonar; active and passive hypersonar suites
Effective Range : Approximately 70 nautical miles

Hypersonar technology relies on a combination of 'traditional' acoustic monitoring equipment such as active and passive sonar, and laser-based range finding, it stands for Hypersonic Navigation and Ranging; as the name implies, it uses faster-than-sound technology to detect shipping, map terrain and aid in navigation. The Trident class mounts a total of 3 parabolic hypersonar arrays mounted bow, stern and the ventral hull. Flight 1 and 2 vessels maintain a fourth, towed sonar array between the main propulsion units.

Operating passively, hypersonar sensors are able to work in conjunction with the ship's computer to use repeated, low-band particle beams to build up a 3D picture of the environment while an integrated passive array intelligently detects and identifies acoustic signatures within that environment. This is the preferred method of operation, as it maintains complete stealth capability for the submarine while still providing at least a marginal picture of the environment around the vessel - while there is no guarantee that a submarine will be detected by the passive components of the array, the laser array ensures that even if targets cannot be identified, they will be detected, ranged and targetted. Only next-generation active camouflage systems employed by Macronesian vessels have the capacity to evade passive hypersonar entirely.

Used actively, hypersonar becomes a double edged, but ultimately infallible sword - First sweeping the area with a high-sensitivity laser array to gather preliminary data, the ship's computer then isolates targets of opportunity which are then battered with a series of uni-directional audio pings, the system literally bounces sound waves off specific solid objects in the water repeatedly and reflects them back to the array, with each ping building up an incredibly detailed picture of the target in real time. The only draw back to this system is that the target being 'illuminated' will also have access to the same information - active acoustics work both ways.
Nonetheless, the system is a marked improvement over first-generation active sonar technology used throughout the later part of the 20th century where a single ping could be detected by any submarine in the area. The new directed-array used in hypersonars will limit the 'saturation' of the ping to one specific vector, thus maintaining the submarine's stealth against any other target in the area. Only a sophisticated inter-ship battle network (Such as the encrypted, globe-spanning communications system used by the UEO military) would be able to make use of another ship's sensor information in real time, and forces which do posess such communications ability are very rare; most certainly, the Battlenet has been one of the UEO's major advantages over the Macronesian navy's own (and significantly less advanced) command and control network.

Combining active hypersonar on a single ship with such a network between a taskforce would enable an entire battlegroup to receive real-time and incredibly detailed target information without revealing their locations.

The Trident class was the workhorse of the UEO Navy's submarine force during most of the 2020s. One of the first "next generation" submarines utilizing technology born of the third world war and the subsequent seaQuest class DSV, Tridents are both durable and effective warships that to this day form the largest arm of the submarine fleet. They are armed with 6 auto-loading 21-inch torpedo tubes and a pair of SMR-70 medium range pulse laser cannons. Their magazines can stock up to 50 torpedoes, and their laser batteries are powered by the ship's nuclear reactors. (On earlier submarines of the class, this meant that power to the 20-megawatt lasers was limited by what the Fission core could provide)

EVA Assets:
Negligible; air locks can support 2 externally-docked shuttles

Crew Complement:
124 (Includes 21 officers and 103 crew)


Development history and class background...

The oldest and most abundant UEO Attack Submarine still in service to the fleet are the Trident class SSNs. First launched in 2023, the Trident was designed to provide the UEO with a submarine that could hold the line of UEO Interests in places where larger fleet assets were unavailable. They were the last submarine of any navy in the world to be powered by fission reactors, as the Tokomak Fusion cores quickly began to push conventional nuclear reactors out of service. Initially, the Trident held dual roles as both Nuclear Attack Submarine and exploration vessel in her earliest days. They were built with many of the design features of the seaQuest in mind such as the feature of a bio-organic hull skin and many of the same Sonar systems. In addition, the Trident was built with many of the design characteristics of NORPAC's Virginia and Seawolf class SSNs

The 2030's saw the introduction of newer UEO submarines to counter the massive build up of Macronesian Orion-class submarines which, in many respects, outclassed the Tridents. As such, the Trident within only 6 years of operation was becoming redundant as the Nuclear Reactors of the submarines limited the power that could be provided to its engines and power-hungry laser weapons systems. It was not helped by the fact that the new Defender class would be coming in to service within only a couple of years.
"Flight II" and "Flight III" versions of the Trident submarine featuring updated sonar and weapons systems. Fusion reactors have begun to appear in the fleet and make the Trident stand as one of the more capable Attack Submarines on the world's oceans.

Despite playing underdog to the UEO navy's faster and more reliable assets, the Tridents have nonetheless shown they are capable of holding their own in many a situation. From the years of 2025 through to 2040, the Tridents held the one thin blue line that kept the Macronesian Alliance from invading the UEO's borders and even with the advent of the UEO-Alliance war, the presence of the Trident along many backwater trade routes of the United Earth Oceans has kept Macronesia from taking advantage of otherwise udefended trade convoys and supply lines.

Trident class SSNs were among the fleet that defended the withdrawal of UEO forces from Hawaii in early 2041, and many of their number (especially flight-one Tridents) were lost in the battle.
