The Trident-class frigate refers to a multi-mission configurable frigate class designed and constructed by the Argis-Marenesia Maritime Industries, a joint Iverican and Gallambrian consortium for naval technology developers and shipbuilding services. The project was known within AMMI as AMMI PROJ. FF-71918; and known as the Future-Frigate Program by the Gallambrian and Iverican governments. Member states of the TRIDENT also committed varying amounts of financial assistance to the project.

Though the Trident-class refers specifically to a base frigate design that can be mounted with differing mission configurations, 3 different pre-configured variants were stipulated as an additional objective of the Future-Frigate programme. All variants contracted had a baseline capability to conduct Air-Defence and Anti-Submarine Warfare with the potential for ship-to-ship engagement depending on what missiles were loaded in the vertical-launch and amidships hardpoints. Flight I-A features surface combat systems and anti-submarine equipment. Flight I-B specialises in mine-laying, mine-countermeasures, in-land fire support, and anti-submarine warfare. Flight I-C is a command ship equipped with enough instrumentation, processing, and intelligence suites to serve as a small flagship; Flight I-C also features several Electronic Warfare systems like radar jammers and electro-optical jammers.

Currently, three variants are designated Flights: I-A, I-B, and I-C. All three passed trials and are in production in the Súbic Naval Yards with production licenses granted to Gallambrian builder Mainwaring Trent. The designation "Trident-class" is an internal one and might be re-named depending on the military employing the ship.

Development

FFG-222 Trident in earlier stages of construction

The Trident-class was initially designed with the goal of providing TRIDENT nations with a flexible, configurable, and affordable hull design. In 2014, Iverican naval shipbuilder Manille Consolidated Maritime and Gallambrian peer company Mainwaring Trent began a project to design a large frigate hull that was compatible with the existing Iverican MIMiK. The design parameters also called for the use of newer 17-7PH stainless steel for cast and panelled sections of the hull and bulkheads. Likewise, parameters also required the use of light-weight precision-tooled cupro-nickel for internal fixtures and some surfaces. The joint-project delivered a test model in 2016, to much success. The hull design received positive remarks for its relative mass to size ratio—largely thanks to Manille Consolidated use of its new stainless steel and cupro-nickel alloys.

In June of 2016, both Manille Consolidated and Mainwaring Trent began a joint effort after receiving identical Requests for Proposal (RFP) from both Gallambrian and Iverican governments. The RFPs of both governments were consolidated as the Future-Frigate Programme later that month and outlined the requirement of a flexible Future-Frigate design that could be equipped for Anti-Submarine Warfare, Mine Warfare, and Command roles. In August of 2016, the keels for three test units were laid in the Súbic Naval Yard, Dock Complexes C, D, and E.. Construction of the test units were conducted within Súbic's special projects area and within covered docks and proceeded quickly thanks to the complex's access to mechanised gantries and retractable scaffolds.

By April of 2018, both companies underwent a merger into a jointly-owned consortium, Argis-Marenesia Maritime Industries, which would officially continue development and pre-production. In May 2018, both governments oversaw trials by competing companies expecting entries to be in the near-finished state of development. After a 3-day run of trials, AMMI was announced as the contracted party for the consolidated Future-Frigate RFP. Part of AMMI's contract included an order to begin building a further 5 vessels of the same design, to be commissioned if test units passed Armada review.

In July of 2018, limited details released to the press stated that the AMMI test units were "nearing completion". The development stage of the project had gone over-budget by an estimated $100 million standard units. To cover the concern and mindful of further budgetary needs, AMMI extended private placement, corporate bond, and other issue offerings to members of the TRIDENT.

Though the shipbuilding phase of the project began in 2016, the Trident-class development would experience a number of delays and re-designs. The test units completed sea trials and pre-production in early 2019, almost a year behind schedule. Initial requirements placed on the project by the Iverican Armada were far too ambitious; total vertical launching cells had to be reduced, along with the total cancellation of the proposed collapsing helicopter pad for the AMMI Snow Cub unmanned rotorcraft. Successes and innovations were also noted by the team. Extensive use of 3D modelling, printing, and new simulation software allowed the team to correct structural faults well-before pre-production; arguably, this measure saved time and capital.

Nevertheless, three hull configurations passed the Armada Iverica review. In April of 2019, one functional test unit per configuration was delivered to the Súbic Naval Proving Zone. These were: Test Unit variants I-A, I-B, and I-C; dedicated surface combatant, shore-warfare ship, and command ship respectively. All variants had a baseline capability to conduct Air-Defence and Anti-Submarine Warfare; though each of the variants also possessed specialised modules or equipment that others did not. All flights passed a shakedown series of manoeuvres and live-fire exercises conducted over the course of 3-days. 1 month following the Iverican admiralty submitted a request to have several allegedly "redundant" test modules removed from the final pre-production models. As a result, the Trident-class carries a number of empty mounting points which were to carry modules classified to be "Fitted-For But Not With" (FFBNW).

All 3 test units were commissioned into the Armada Iverica in June 2019. During this time the 5 additional Trident-class frigates on-order were already being built in Súbic Naval Yards, Manille Yards, and in Altaria Shipworks.

Flight II

A second flight had been planned in 2018 after a design review by the joint Gallambrian-Iverican committee for the Future Frigate Programme. Published commentary following the review expressed concerns over the application of some weapon and sensor systems. The Future Frigate Committee decided that withholding some of these systems for a second flight would be more practical. A secondary point of contention was on the design of the aftward deckhouse. Among the 2 proposed designs, the committee decided to approve the asymmetric deckhouse design for Flight I, holding future reconsideration for a redesign as a possibility pending Flight I's actual performance data. The asymmetric design would be competing against the initial mirrored deckhouse design initially favoured for its lower Radar Cross-Section. Before pre-production in September 2018, the mirrored deckhouse

The Armada Procurement Office also decided that it would limit its orders of Flight I Tridents to 13 ships. A tender for 3 Flight II demonstrators was signed early to keep the shipbuilders in constant operation with provisions to commission the demonstrators if they met review standards.

Production of the demonstrators began in January 2020 and was completed in November 2022. On average, this was exceptionally quick for the Manille Yards which had taken more than 3 years to complete the demonstrators for the second flight of Verde Sea-class frigates. The timeline had been expedited by AMMI's use of 3 already-finished Flight-I hulls. A further factor hastening the process was the presence of 2 partially completed aftward deckhouses, which had initially been built in anticipation of the mirrored deckhouse design. With 2 ships complete, the committee pushed trials ahead from the initially planned July schedule, counting on the performance of the 2 sister flight variants to stand in for the then-unfinished Flight II-A. A TRIDENT press release cited the growing tensions in the Adlantic Ocean as a factor in the alterations to Flight II's timeline.

In January of 2023, both the Flight II-B and Flight II-C demonstrators were commissioned as the VRI Ronconé (FFG-235) and VRI Sarissa (FFG-236) respectively.

II-A: Surface Warfare, Multirole

II-B: Shore Warfare, Mine Warfare, Anti-Submarine Warfare

II-C: Air-Defence, Electronic Warfare, and Command & Control

Flight II featured a new mirrored deckhouse design which simplified production and decreased the ship's overall RCS at the expense of slightly greater mass. New electronic systems integrated were the RI/WSC-9 broad-frequency system, the RI/SLQ-45 communications frequency jammer, the SPY-203 AESA radar, and electro-optical fire-control systems. New armament improvements were the Diluvio Internal Magazine Torpedo System, the TORINT Submarine Munition Countermeasure, the Hydra combined gun-missile CIWS, and the Salamander Launcher - standardised class-3 missile deck launchers for the waist-mounted missiles.

Other major changes included the removal of 2 of the 4 boat bays, the full integration of the TKWA MASS countermeasure system for all flights, the integration of electro-optical dazzlers for all flights, repositioning of the 3x 16-Cell VLS systems, and the installation of an amidships mast to mount the SLQ-45 jammer. There were also Flight-specific changes. Flight II-B was equipped with a 155 mm naval gun to enhance its shore bombardment mission and was given a dedicated hull-mounted sonar on the bow. Flight II-Cs were built with an additional tower for the SMART-L radar and had an additional forward mount for the RI/SLQ-101 Sirena directed jammer. All mounts for continuous-wave illuminators like the SPG-62 on Flight I ships were removed as Flight-II ships would switching their air-defence missile loadouts to units with active radar guidance.

Variants

Three veriants that had passed trials were initially designed, built, and tested in Iverica. The Flight I-A, Flight I-B, Flight I-C. According to Armada Iverica ship classification conventions, ship "flight" alphanumeric designations are set by one aroman numeral (e.g. I, II, III, IV) denoting the series of the hull and its major physical features; and one letter (A, B, C, D) denoting a configuration of equipment. All variants contracted had a baseline capability to conduct Air-Defence and Anti-Submarine Warfare with the potential for ship-to-ship engagement depending on what missiles were loaded in the vertical-launch and amidships mounts.

The Excalibur Subclass of the Trident referrs to Trident class baseline units finished in Gallambria by shipbuilder Mainwaring Trent. Excalibur-class units are nearly identical but typically differ in type of armament. Requiem missiles are usually not present on Excalibur models. Likewise, Orthros CIWS units on the Excaliburs are typically replaced with Gallambrian systems.

After trials, the Iverican Ministry of Defence chose not the re-designate the class. The Tridents entered Armada service under the same name. Beginning with FFG-222, most Iverican ships are named after Polearms or significant TRIDENT operations. FFG-225 Atgeir, is named after the Atgeir joint naval exercise, the first organisation-wide training event. An Atgeir is also the name of a Northern-Argic hewing-spear. Currently, the Iverican Armada operates 6 out of the 12 active units, with 36 more units on order. The Ministry of Defence is considering opening a second shipyard in Nou Stille to expedite production.

While technically a subclass, the two test ships FF(X)-220 and 221 are not considered fit for military service. FF(X)-220 suffers an irreparable warp to its keel sustained from testing manoeuvres during its earlier iterations. FF(X)-221 served as a testbed for an entirely different interior layout that used aluminium parts. Upon review, AMMI determined the the currently available aluminium shipbuilding materials were unable to meet their corrosion resistance and cost cieling standards. FF(X)-220 is due to be scrapped by the end of 2021, while FF(X)-221 is due to be redesignated a research and exploratory vessel for the Iverican Ministry of Applied Science and Technology.

Thanks to the MIMiK system, all variants have the ability to be quickly refitted to fulfil some degree of another variant's role.

Stock systems that are equipped on all flights:

• Armaments:
  • At least 1 x Orthros CIWS- a variant of the Sagittario CIWS using 25mm autocannons and 2 x octo-racks of MVI-66 instead of the Sagitarrio's 30mm and 2 x quadracks of MBI-90.
  • G-42, Mod 2- a 32-cell Vertical-Launch System.
  • 2 x G-42, Mod 4- an 8-cell Vertical-Launch System.
  • 25mm ARX Chainguns
  • 12.7mm Remote Machineguns

  • Fortis Defence Electronics Masted EW & ESM System
  • Manille Systems RI/SQS-53 (hull sonar)
  • Manille Systems Multi-function Variable-Depth TAILS 2087- a towed radar array with the ability to be deployed at selected depths in the water column.
• Countermeasures:
  • Chaff and Decoys- to counter radar, active-laser guided, and infrared-seeking systems.
  • Sonar Decoys- trailing decoys receiving, amplifying, and returning "pings" from an enemy torpedo, presenting a larger false target to the torpedo.

Flight I-A

Broadside illustration of a Flight I-A vessel.

A dedicated surface combatant with air-defence and anti-submarine capabilities. Flight I-A was conceptualised as a cost-effective solution to fielding destroyers. Much of its armaments and systems are comparable to that of a small destroyer. Given that the Flight I-A production cost is approximately half of an Ancile Combat System General Luna-class destroyer, it is argued that the Flight I-A provides the quantity of ships needed for comparable roles while also being much less of a financial loss if damaged or destroyed. Recent commentary at press events suggests that the Iverican Armada plans to minimise future production of destroyers and lighter frigates, fully focusing on deploying formations of heavier frigates like the Trident-class.

Flight I-A carries all baseline modules that her sister ships carry. Though it is equipped with considerably more anti-ship missiles and missile interceptors.

Notable Sensor Systems

• KG/SPG- Gallambrian built dedicated fire-control radar that searches a narrower beam but yields high targeting-quality radar data and is rated to track small, very fast moving surface and aerial targets.

Notable Armaments

• 76mm ARX Rapid Gun- a naval gun capable of firing 120 rounds per minute. Utilises different ammunition types making the gun ideal for engaging swarms of surface targets or fast-moving aerial targets.
• MVS-84 Block II- a near-sonic sea-skimming missile armed with a variety of electronic countermeasures and evasive programming. A cost-effective, short-range (280 km), anti-ship missile. Trident-classes may carry 2x quad-launchers amidships. Though the amidships hardpoints are capable of bearing the launchers, most Trident-classes will carry the MVS-220 triple launchers instead.
• MVS-220- Armada designation for the supersonic, ramjet Requiem Missile. A much faster, but much larger sea-skimming missile for engagements at medium range (650-700 km). Trident-classes may carry 2x triple-launchers amidships.
• ME-DE-1 (MVS-101)- a vertically-launched, supersonic, sea-skimming, anti-ship missile fired from a G-42 Vertical-Launch System. Trident-classes may have any number of these inside its 40 cells carried.
• ME-DE-2 (MVS-102)-a vertically-launched, supersonic, sea-skimming, anti-submarine missile. It consists of three stages, one booster with a thrust vector nozzle, one conventional booster, and one anti-submarine light torpedo. The system does not require an exact lock; the third-stage torpedo is capable of seeking sonar signatures independently over a small area.
• TVU-54- a light, short-range (9.1 km) torpedo capable of active, passive, or semi-active acoustic guidance. Trident-classes may carry 2x triple tubes amidships or in in the quarterdeck. If amidships anti-ship launchers are removed, Tridents can carry 4x triple tubes for a total of 12 torpedoes.
• MVI-201- also known as the ANCILE-1 missile; supersonic interceptor missile capable of shooting down missiles or aircraft. Is also known to be capable of an anti-ship role, but suffers from a slow, gliding terminal stage and high-angle of attack when in this mode.
• MVI-80DE- also known as the Golondrina missile; a compact surface-to-air missile designed to counter supersonic manoeuvering anti-ship missiles. May be quad-packed into one G-42 VLS cell. Usually equipped on all Trident-classes

Notable Countermeasures

• 2 × Towed decoy array (acoustic and magnetic)

• Flight I-A systems
•

• 

  TVU-54 torpedo launched from a Trident-class frigate

• 

  KG/SPG-62 fire-control radar

• 

  an Orthros CIWS; armed with twin 20 mm guns and 2 octo-racks of MVI-66.

•

Flight I-B

An AMMI Snow Cub loitering.

Flight I-B was conceptualised out of the perceived necessity to maintain an ocean-going vessel capable of keeping up with carrier formations and then providing mine-sweeping and countermeasures capability once in the Area of Operation. Its mine warfare and anti-submarine specialities were integrated as a cost-saving measure; both missions require an indexed capability to deploy sonar sensors effectively. The decision to include an in-land fire support role came out of I-B's perceived operating environment; noting that mine-warfare operations already happen in and around littoral zones, the Trident design team decided to integrate the mission with I-B's already expansive capabilities.

Flight I-B fulfils the role of a group escort that could provide the baseline roles (air-defence, escort) while armed with specialised sonar sensors and land-attack armaments for its primary roles of mine warfare, anti-submarine warfare, and in-land firesupport. I-B carries a hull sonar, towed variable-depth sonar, sonobuoys, torpedoes, unmanned underwater vehicles, and a rotorcraft equipped with mine detection and mine-neutralisation modules; I-B may also carry 2-4 unmanned, mine-countermeasures equipped rotorcraft in place of the manned utility rotor. These rotorcraft and sensors are also used for anti-submarine warfare; the I-B comes further equipped with a RI/SQQ submarine warfare system that acts much like the ANCILE Combat System, allowing for the quick communication of surveillance sensors and guidance sensors to neutralise an enemy submarine. For in-land fire-support, this configuration is also armed with land-attack versions of the Requiem missile in addition to its 12.8 cm naval gun. Its vertical-launch system may also be equipped with land-attack versions of the ME-DE cruise missile.

Notable Sensor Systems

A dipping sonar being lowered from a SUR-31V helicopter

• RI/SQQ-89 Submarine Warefare System- The system presents an integrated picture of the tactical situation by receiving, combining and processing active and passive sensor data from the hull-mounted array, towed array and sonobuoys. SQQ-89 is integrated with the ANCILE combat system and provides a full range of undersea warfare (USW) functions including active and passive sensors, underwater fire control, onboard trainer and a highly evolved display subsystem. It provides detection, classification, and targeting capability.
• Detection Systems on Rotorcraft and Underwater Vehicles- Snow Cub, SUR-31V, and a UUV can provide laser or sonar surveillance. Rotorcraft use an airborne laser mine detection system for sea-mines and a dipping sonar for submarines. The UUVs mount a RI/AQS-20A sensor system; they are capable of magnetic and acoustic detection.

Notable Armaments

ME-DE-2's third-stage vertically-launched torpedo.

• 128/64 ARX GNL- a long-range naval gun for main-line surface warfare combatants. Can engage aerial and surface targets. Can be loaded with a satellite-guided rocket-assisted munition for in-land fire-support at a range of up to 100km.
• MBT-220- a land-attack version of the Requiem Missile. Trident-classes may carry 2x triple-launchers amidships.
• ME-DE-2 (MVS-102)-a vertically-launched, supersonic, sea-skimming, anti-submarine missile. It consists of three stages, one booster with a thrust vector nozzle, one conventional booster, and one anti-submarine light torpedo.
• TVU-54- a light, short-range (9.1 km) torpedo capable of active, passive, or semi-active acoustic guidance. Trident-classes may carry 2x triple tubes amidships or in in the quarterdeck. If amidships anti-ship launchers are removed, Tridents can carry 4x triple tubes for a total of 12 torpedoes.
• Airborne Mine Neutralisation System- carried by rotorcraft; the RI/ASQ-235 uses a handling system and a neutraliser vehicle carrying an armour-piercing warhead. Once a threat is detected, the system is deployed by rotorcraft and lowered to the vicinity of the mine. The warhead is fired and the mine is detonated.
• Snow Cub Guided Rockets- the AMMI Snow Cub may be fitting with a pair of rocket pods containing 4 semi-active laser homing rockets each.
• G-65A Airborne Sea Mine- a magnetic sea mine which can be dropped from the ship's rotor complement.
• G-66R Sea Mine- a 200 kg remotely controlled mobile mine deployed from the aft slip bay.
• G-67T Torpedo Mine- Comprised of a torpedo canister, cable, and anchor, the G-67T sinks when deployed until its computerised acoustic or magnetic fuzes are triggered. The G-67T then fires a light-weight, short-range homing torpedo at its target.
• I-B may also carry any other missile system that is compatible with the G-42 VLS.

Notable Countermeasures

• Additional Towed Acoustic and Magnetic Decoys
• Fortis Defence Electronics Electro-Optical Jammer and Laser Warning Suite (Flight I-B)
• TKWA/MASS (Multi Ammunition Softkill System)- originally designed to come stock on all Trident-class configurations, the Soft-Kill system was later removed as a cost-saving measure. It remains on the I-B as the ship is the most likely to encounter small rocket or missile weaponry while conducting its close-to-shore operations.

Flight I-C

Flight I-C features expanded Command & Control facilities.

The Flight I-C Trident-class is a command configuration of the Trident-class. While retaining the capability to be armed with anti-ship missiles and torpedoes, I-C also carries a wide array of signals equipment and command & control facilities. Additional surface and air search radars permit the I-C to constantly monitor an area of operations. ESM equipment allow for intelligence gathering while additional operations rooms allow more command or intelligence staff to operate synchronously.

This configuration is also equipped with radar jammers, expanding its role to include electronic warfare. Within a group, the I-C can support units by jamming enemy aircraft, drones, or nearby ships and land installations. I-C's Sirena jammer can also be used to cause a communications blackout over a certain area; limiting the use of radio or cellular communications. Additionally, the I-C can act as a missile instrumentation ship, tracking long-range launches.

Notable Sensor Systems

SMART-L Radar

• ANCILE Baseline C- a much more sophisticated radar suite comprised of the SPY radar, an additional surface and aerial search radar, and instrumentation and designation radar.
  • SMART-L Radar (additional)- for long-range, high-volume search.
• GAe Systems Occulus ESM- a passive listening suite that allows for analysis of a variety of different frequencies and bands of detected signals.
• Fortis Defence Electronics Noosphera Shipboard Command Suite.
  • Capable of HF, UHF, VHF, SHF, and encrypt/decrypt.
• Dedicated space for additional command & control facilities.

Notable Armaments

an IR lamp part of the Electro-Optical jamming suite

• 76mm ARX Rapid Gun- a naval gun capable of firing 120 rounds per minute. Utilises different ammunition types making the gun ideal for engaging swarms of surface targets or fast-moving aerial targets.
• MVI-201- also known as the ANCILE-1 missile; supersonic interceptor missile capable of shooting down missiles or aircraft. Is also known to be capable of an anti-ship role, but suffers from a slow, gliding terminal stage and high-angle of attack.
• MVI-80DE- also known as the Golondrina missile; a compact surface-to-air missile designed to counter supersonic manoeuvering anti-ship missiles. May be quad-packed into one G-42 VLS cell. Usually equipped on all Trident-classes
• I-C may also carry any other missile system that is compatible with the G-42 VLS.

Notable Countermeasures

• Electro-Optical Jammer and Laser Warning Suite- Infrared dazzlers and Directed-Infrared Countermeasures. Can be used to
• RI/SLQ-101 Sirena Jamming System- intended to jam AWACS/AEW&C aircraft or drones. Can also be used to jam communications.

Additional Systems Carried

• The I-C has space for an additional 2 RHIBs or two armed ROVs launched from an aft slip bay below the helicopter landing deck. The slip bay can also house a single narrow-body assault boat in place of 2 smaller boats. The I-C can carry a total of 6 boats, making this configuration capable of larger than normal amphibious sorties.
