The Krotos-class Heavy Destroyer, also known as the Krotos-class Fleet Destroyer, is the workhorse of the Unified Ionian Navy. Designed and constructed by Hydar Fleet Systems as part of the Ionian League’s New Navy Modernization Programs of the early 3400’s, the Krotos-class was designed to replace the aging Nikon-class Destroyer and signaled a shift for the UIN from a destroyer-squadron mentality to independently operating destroyers serving in a long-range, patrol focused role. 

The Krotos-class Heavy Destroyer has seen use in a myriad of operations since its inception in 3400's, and has steadily earnt its place as the poster-child warship of the Unified Ionian Navy, romanticised alongisde the likes of the Hyperion-class Battleship in Ionian modern fiction and holoseries.

Development History


In the decade running up to the turn of the 35th century the Ionian New Navy Modernization Program was in full swing. The Krotos-class Fleet Destroyer is the the fourth starship in the new line of warships coming out of the New Navy program, following the Mikros-class Corvette and the Pilikari-class Heavy Frigate. Designed by Hydar Fleet Systems, the Krotos-class is intended to improve upon the already successful yet outdated systems of the Xiphos-class Destroyer as well as to improve the cost effectiveness of the UIN. 

Since the end of the Ionian Wars the Ionian League had relied upon squadrons of destroyers and frigates to patrol its borders. In the decades immediately following the Great Ionian War these large clusters of starships fulfilled their roll of re-establishing and maintaining order within a war weary Ionian League. However as the 35th century fast approached it became painfully evident that the Ionian League could no longer array such large sections of warships simply to patrol shipping lanes and border posts. Thus the Krotos-class was developed to act completely independently of its assigned battle fleet.

Already contracted by the Ionian government to produce naval hardware for the UIN, the Carthagus based corporation of Hydar Fleet Systems was contracted to further design and develop a new line of Destroyer class vessels with this sole purpose in mind. With the Mikros-class Corvette and Pallikari-class Frigate already in full production by Katena Heavy Industries, Hydar Fleet Systems built upon the previous classes of starships whilst taking over and improving upon the already existing and proven systems of the Krotos-class’ predecessor; the Xiphos-class Destroyer.

Operational History


Though performing an active role in the UIN prior to 3410, the Krotos-class made a name for itself during the Peripherian League backed Tolean Intervention, serving as a long range deterrent to recidivist Tolean hit-and-run actions along Peripherian supply routes in and out of system.
