Triumph-class destroyer

Triumph-class destroyer

The Triumph-class is a class of twenty-two Invenian Navy guided-missile destroyers. With 32 ships planned, an overall length of 160m to 175m, displacement ranging from 8500 tons to 11000 tons, and weaponry of 90 - 120 missiles, the Triumph-class is significantly larger and more numerous and powerful than any other destroyer class of the Invenian Navy. They are designed to replace the 6000-ton Hunter-class destroyer built in the 1970s.
The lead ship, USIS Triumph, was commissioned in 2002.

Characteristic

---

Variant
The Triumph-class have 5 separate variants, refers to as Flights. Each flight incorporate new technology learned and is incrementally larger and more powerful than previous flights.
Flight I: DD-62 to DD-65
Flight IIA: DD-66 to DD-69
Flight IIB: DD-70 to DD-74
Flight III: DD-75 to DD-79
Flight IV: DD-80 onwards

Structure
The Triumph-class ships are the largest destroyers built in Inven, with the Flight IV ships almost doubled in tonnage compared to the previous 6000-tons Hunter-class. The class's design incorporates stealth techniques such as angled surfaces and reduced usage of right angles. Due to fire concerns, the ships in the class are constructed using steel instead of aluminium, unlike the Hunter-class.

Development

Origin and Flight I
From the 1990s it was clear to naval analysts that the Hunter-class was becoming outdated and obsolete in terms of armament compared to VLS-equipped vessels and in terms of protection against newer models of sea-skimming missiles. As stopgap measures, the Hunter-class Block II was introduced in 1990 featuring a new vertical launch system and improved sensors and electronics before a new class of destroyers could be designed.
In 1991 the Invenian Navy initiated design studies with four contractors: Sanaii Heavy Industry, Invenian Shipbuilding Company, Naris Shipbuilding and Howe Navy Yard. By 1994, it was decided that the new class of destroyers would be built in flights, in which each flight is incrementally larger than the previous flights in tonnage and dimension and incorporate new technology as well as lessons learned from the construction of previous ships. It was envisaged that the final flights of this new class of destroyer would have a displacement of more than 10,000 tons.
Budget shortage lead to design restrictions for Flight I, including a displacement capped at 8500 tons and the absence of aviation facilities. In 1996 the Navy contracted the Invenian Shipbuilding Company, Naris Shipbuilding and Howe Navy Yard for the construction of the first four ships of the class, Triumph, Intensity, Victory and Tenacity. USIS Triumph was laid down by the Invenian Shipbuilding Company in 1999, launched in 2000 and commissioned in 2002.

All four Flight I ships were upgraded twice, in 2012 and again in 2022 to incorporate new sensors and weaponry.

Flight IIA
With the introduction of the rather controversial Military Expansion Act of 2000, the displacement limit was lifted. Nevertheless, the Navy was still limited to the production of one destroyer per year. Thus, it was announced that Flight IIA (at the time referred to as Flight II) would be built with a larger hull and equipped with aviation facilities that could accommodate Hornet drones and/or Penguin ASW helicopters, and better datalink enabling it to communicate with other warships or important military assets. The first Flight IIA ship of the class, USIS Impulse was laid down by the Naris Shipbuilding in 2003, launched in 2005 and commissioned in 2006.

All four Flight IIA ships were upgraded in 2016 to incorporate new sensors and weaponry.

Flight IIB
The Flight IIB design was introduced in fiscal year 2004 as a modest upgrade to the Flight IIA iteration of the ship. Newer radar and electronic systems were installed, and the Orca Combat System's interface was improved. The first Flight IIB ship of the class, USIS Dauntless was laid down in 2007 by Howe Navy Yard, launched in 2008 and commissioned in 2010.

All five Flight IIB ships were upgraded in 2021 to incorporate new sensors and weaponry.

Flight III
The Flight III design was announced in fiscal year 2010 as a scaled-up Flight IIB design with new and more powerful machinery, which made them the first Invenian Navy destroyers to exceed 10,000-ton displacement and the first Invenian warship to be equipped with more than 100 missiles. The flight featured for the first time a touchscreen interface for the Orca Combat System. The Flight III ships use AESA radars with larger radar antennas instead of the earlier PESA radars installed on previous ships, which improved sensitivity to targets and resistance to jamming. The first Flight III ship of the class, USIS Express was laid down by the Naris Shipbuilding in 2012, launched in 2013 and commissioned in 2015.

Flight IV
Flight IV was announced in fiscal year 2015 to be the final enlargement of the Triumph-class designs. At 11,000 tons and 175m long, they are equal in size and armaments as contemporary guided missile cruisers. The Chief of Staff of the Invenian Navy noted the reason why 11,000 tons is the limit "Any additional increase in displacement will compromise the class' flexibility and incur additional cost to the program".

Other than its heavy armament, Flight IV ships features increased amount of protection compared to previous ships of the class. Vital areas were up-armoured significantly to improve survivability. For instance, the new Mark 4 VLS featured armour for anti-splinter protection, an evolution of the unarmored Mark 3 installed on older ships.

Flight IV vessels are the first vessels in the Invenian Navy to feature an integrated AI system codenamed "Compass" with the Orca Combat System, allowing commanders to have greater situational awareness on the battlefield. The AI is capable of suggesting the best course of action and controlling other autonomous assets on the ships such as the Hornet UAVs. In the scenario where the captain and the command staff are killed in action with no one in charge and communication with Navy Headquarters and other warships has been completely cut off, "Compass" can take control of the ship and authorize orders. With a high degree of automation, crew size is reduced compared to flight III ships.

Datalink between ships and other assets are improved significantly, especially between Compass-equipped ships. This means that these ships can shares target data with each other and jointly determine the best firing solution.

After the introduction and passing of the even more controversial 2020 Military Expansion Act, also called the Second Military Expansion Act which lead to the 2020-2021 Invenian political crisis, the Invenian Navy was able to accelerate its destroyer construction, increasing to 2 destroyers a year from 1 destroyer a year by expanding shipyards and remove the 1-year break between the launching of completed ships and laid down of next ship. As such, Sanaii Heavy Industry was included in the contract for the production of Flight IV ships starting in 2020.

The first Flight IV ship of the class, USIS Pioneer was laid down by the Invenian Shipbuilding Company in 2017, launched in 2018 and commissioned in 2020.
