The Project 17100 destroyer, sometimes known as Aribango-class destroyer is a family of guided-missile destroyers (DDGs) in service of the Unifying Navy. The class was conceived in late 1980s as a secondary effort in designing primary capital ship of the resurgent Navy, capable of conducting anti-aircraft warfare, anti-submarine operations, anti-surface combat in sustained actions, ground-strike missions, and long-range surface raiding operations. Design effort included study of Zacapine, Rezese, Redisan, and Elatian capital ships and their surface actions, and involved technical assistance from the Oxidentali nations.

All ships of the class are named after the cities in the Two Basins, including both the Autocracy and Amayana Makgato Federation cities. The lead ship, Aribango, was built in Gallentica Naval Works shipyard in Orun Redisus, while all other ships were built on the Shipbuilding Plant No.113 in the Imo Basin. Seven have been completed by 2024, with another three to enter service in the next five years, replacing older Project 14460 destroyers in service.

Development

The Unifying Revival, spearheaded in the lower Karana by the Solar Temple of Yanbango was characterized, among other things, by intense, lengthy, and often heated discussions in the internal periodic papers of the Temple Missions in various countries. The recurring theme was the composition of the future navy of the Temple State, with discussions involving priests, apprentices, a few students training in various military academies, and occasional invited experts from the navy of the country the particular mission was situated. Most vocal proponents in the Elatian and Zacapine missions eventually took the upper hand, while debating between themselves about the composition of their desired fleet. By the time the Itayana Navy was re-established in 1988, the priesthood and the Captains' Council of the Navy were unified in that the blue-water navy would need three types of combat ships: an aircraft carrier as a C3I, air defence, and strike ship; a frigate as the main multi-role ship of the fleet; and a capital ship.

The desired frigate formalized as the Project 15470 program, and its design process, based entirely around proven and tested systems, met the least difficulties between the three. The carrier program, while initially considered economically impractical, unexpectedly materialized with the help of the Burning Sun initiative in 1996 as the Project 11431, a reconstruction of an unfinished Elatian aircraft cruiser. Clauses of the Burning Sun funding included provisions to test certain systems to be employed in the Zacapine Navy, a decision that led to numerous problems in ship's sea trials. The capital ship program materialized as the Project 17100.

Requirements for a future capital ship of the Navy were debated and discussed through late '60s, '70s, and '80s. Said debates involved extensive analysis of the Belfro-Mutulese War of 1928, Second Belfro-Elatian War, and Third Uhlangan Civil War, as well as the state and development of capital ships around the world from the various sources the priests could have found. Proponents of the surface raiding doctrine, centered around the Elatian mission, argued that Itayana would never be able to establish a fleet that could oppose numerically superior fleets in open combat, meaning the possibility of raiding hit-and-run tactics was the way to deter possible naval aggression, carefully studying the Second Belfro-Elatian War and surface actions of the Elatian Navy. Their opponents, centered around the Zacapican mission, argued that Elatian raiding doctrine based around submarines and surface raiders, ultimately failed through a series of engagements where outgunned solitary raiders were destroyed piecemeal, and that a few surface raiders complemented with submarines would ultimately prove more expensive than a balanced, if weaker, surface fleet. The discussion fluctuated between doctrinal matters, naval operations studies, and technical studies for over 15 years, and became a notorious point of contention within the Temple ranks.

The final design requirements represented a consensus between the opposing factions. They were made possible by advancements in the propulsion systems, radar and helicopter technology, and introduction of vertical launch systems on the Zacapine destroyers in 1980s. In 1988, with the re-establishment of the Itayana Navy, a set of requirements was made demanding a capital ship that could conduct both the surface raiding operations and the sustained missile combat in the fashion of the evolved battle line tactics, fusing the two points of view. Details on the design process are sparse; it is known that several heavy cruiser and battlecruiser designs from 1920s to 1950s were used as technical templates, as well as more modern guided-missile vessels in size of the capital ships. The final design resembled Elatian heavy cruiser raiders mixed with Zacapine guided missile air defence nuclear-powered destroyers.

The first ship was ordered to the Gallentica Naval Works, the same yard that constructed the first batch of Project 15470 frigates, and under the same 1995 contract. Further ships were built in an expanded Shipbuilding Plant No.113, where three slipways were constructed in late 1990s to accommodate the localized orders.
