The Helena-class is a class of air warfare guided missile destroyers in service with the Meridonian Navy. Designed from the ground up as specialized air warfare escorts for the upcoming Sistine-class aircraft carriers using lessons learned in the 1980s, the Helena-class pioneered a number of new technology systems for the Navy. They are named after territories, districts, and large settlements. They were built starting in the early 1990s, and the first ship, Helena, was commissioned in 199X, with the last ship Caster Ridge commissioning in 201X.
The Helena-class was commissioned shortly after the Otapara-class destroyers began construction when naval planners realized that the Otapara-class would not be able to meet the anticipated fleet needs for a air defense platform, currently provided by the Mystere class of destroyers. Due to the Otapara's general purpose requirements of being capable of anti-air, anti-submarine, and surface warfare and the design of its hull it was determined the class would be better suited to a destroyer leader and multirole destroyer. This was critically important with the development of the Sistine-class aircraft carriers, who were to make up the core of the naval fleet into the 21st century. The Helena-class was also to be a testbed for technology critical to not only the coming carriers, but to the Defense Force as a whole with the advent of the Common Air Defense System, which serves as its principal armament.
The Helena-class is optimized for air defense and operates primarily as an escort destroyer, acting as the Carrier Task Group's principal anti-aircraft platform with supporting roles in anti-submarine warfare with MSU-14 antisubmarine rocket-propelled torpedoes and embarked anti-submarine helicopter, and anti-ship warfare with its eight MSS-33 anti-ship missiles.

The design of the Sistine-class carriers, due to a number of shifting requirements during its development, took a period of nearly ten years from conceptualization to construction. Key to its requirements from the design was the capability to meet or exceed the airwing size carried by the Atlantia-class, have a higher top speed, be capable of landing and launching aircraft simultaneously, and modularity to accommodate emerging technologies and aircraft. Sistine was originally designed to feature integrated electronics propulsion, but the design was altered to operate off of nuclear propulsion.
One of the most recognizable features of the Sistine-class is its dual-island configuration, which is primarily a holdover from the diesel-operated design. The forward island is responsible for ship operations, including navigation, defensive systems, radar operations, and other such functions, while the rear island conducts coordination of air operations, including launches, landings, air battle management, and airspace control. Both bridges are redundant and each bridge can conduct operations of both if one of the bridges is damaged.
Sistine is a CATOBAR carrier that features 4 steam catapults and 4 arresting wires on an angled flight deck.
