The new destroyers were intended to fulfill a niche within Antoran naval doctrine that had never been addressed: long-range independant vessels with heavy armaments capable of engaging any threat. This mission profile, the result of increased pressure via the Royal Cabinet for the Armada to escort domestic shipping long distances, required many complicated changes and additions to the ''Nežeren'' class hulls. The most extensive and prominent of these were the addition of many new weapons systems and entirely new power plant and propulsion architecture. The Tavari-made 76 mm deck gun was exchanged with a 100 mm HerCan Armas-6/T cannon derived from the armament of the [[Gracia de Régne|''Gracia'' class]] helicopter cruiser. The 12-cell [https://en.wikipedia.org/wiki/Vertical_launching_system VLS] missile system was replaced with a larger 18-cell launcher compatible with Antoran anti-air missile designs. This anti-air capability was supplimented by the addition of a Guacamayo TEA-05/Mk2 [https://en.wikipedia.org/wiki/Close-in_weapon_system Close-In Weapons System] on the rear superstructure. In order to perform anti-ship and long-range surface strike missions, four missile tubes with four cells each were added forward of the CIWS on the top of the superstructure. These tubes, also derived from the ''Graciai'' classes armament, can carry sub-and-super-sonic cruise missiles with ranges of up to 700 km. As a final weapons package, two turrets mounting triple torpedo tubes were installed on either side of the helicopter pad, two Porcupíné [https://en.wikipedia.org/wiki/Anti-submarine_mortar anti-submarine mortar] launchers were added to either side of the helicopter hangar, and space for depth charge racks was allocated on the rear boat launch. These armaments, in conjunction with the new ElectroBeam ISSD-5 sonar, provide substantial protection against submersibles for situations where the destroyers are not operating alongside [[Régeñe Natalia Romero class|''Régeñe Natalia Romero'' class]] frigates.
The power plants of the ships were reverse-engineered and redesigned to run cooperatively but independantly from the populsion systems, boosting the available grid capacity of the ships from 1.8 to 6.6MW. The extra power is shunted to capacitors when not in use to provide auxiliary electricity in case of power failure. Another benefit of the increased electrical power is the potential to include more demanding weapons systems in the future. The populsion systems were removed and replaced with a [https://en.wikipedia.org/wiki/Combined_diesel_or_gas Combined Diesel or Gas] (CODOG) drive. The tandem 16-cylinder Ultíma 10kDG-16 diesel engines and the 36kGTG gas turbines provide an overall kilowattage of
Most of the Tavari-made sensor systems were removed in favor of domestic Antoran alternatives to ensure the destroyers were compatible with existing Armada networks. New models of radar, tactical suites, and [https://en.wikipedia.org/wiki/Electronic_warfare electronic warfare] systems were included in this package. The new systems are tied together by the SVA computer architecture, allowing the missiles, guns, and subsurface munitions to each have a dedicated subsystem within the ETRS-8 tactical systems suite. The Lima Alto Maestro system and the AQUILA countermeasure suite are both new developments exclusive to the ''Rége Arturo'' class. They allow the crew of the vessel to detect, infiltrate, and decrypt enemy communications, encrypt and protect shipboard electronic systems, and deal with incoming aircraft and munitions with a variety of [https://en.wikipedia.org/wiki/Countermeasure#Softkill_measures soft kill/hard kill] options.
