The Nerys Ní Maoláin-class destroyer is a class of destroyers, built for and serving with the Royal Ossorian Navy (RON) starting in 2008. The class was the sixth and latest class of guided-missile destroyers built by the RON and represents the most advanced and heavily-armed guided-missile destroyer in Ossorian service.
Design
General characteristics
The Nerys Ní Maoláin-class ships have an overall length of 166 m, a beam of 21.4 m, and a draught of 6.25 m. They displace approximately 8,500 t at standard load. Each of the class' two steam turbines drive a single 5-bladed Variable-pitch propellers and are powered by a single CS-4 LFTR and are rated at 100,000 shaft horsepower. This gives ships of the class a reported speed of approximately 30 knots.
Protection
The Nerys Ní Maoláin-class design makes extensive use of various stealth techniques, such as much of the external hull being sheathed in a continuous all-steel superstructure to minimize the number of protrusions and the resulting exposed surfaces being canted at an angle rather than left presenting a flat surface to reduce the ships' radar cross-section. To reduce combat damage, the class incorporates a variety of passive defenses in its design, including double-spaced armor around the vital spaces of the ship to reduce the effect of modern explosive warheads, and kevlar spall liners being applied on the interior surface of the outer hull to reduce splinter production in the event of the hull being violently breached The class is also designed with an air-filtration system to protect the crew against nuclear, biological, and chemical (NBC) agents and is hardened against electromagnetic damage.
Sensors
The Nerys Ní Maoláin-class ships were designed and built around the Caer Warfare System and its omni-directional active phased array radar. The ships are also equipped with a hull-mounted sonar system and a towed sonar array.
Armament
- One 115 mm/55 calibre gun for use against surface, airborne, and shore targets, mounted on the foredeck.
- Two 30 mm autocannons for use against close-in surface targets, mounted amidships on either beam in single mounts.
- Four 12.7 mm machine guns for use against close-in surface targets, mounted fore and aft of the superstructure on either beam in single mounts.
- Two 30 mm close-in weapon systems for use against close-in surface and airborne targets, mounted fore and aft of the superstructure.
- Two batteries of vertical missile launchers totaling 128 cells capable of launching a variety of surface-to-air missiles, surface-to-surface missiles, and anti-submarine missiles for use against standoff-range airborne, surface, and subsurface targets, with one battery of 48 cells mounted on the foredeck and a second battery of 80 cells mounted on the afterdeck.
- Four quad-canister anti-ship missile launchers for use against standoff-range surface targets, mounted amidships between the forward and aft superstructures and trained outward of either beam.
- Two triple torpedo tubes for use against close-in subsurface targets, mounted on the afterdeck on either beam.
Aviation
The Nerys Ní Maoláin-class ships are outfitted with a helicopter hangar and a flight deck on the stern and are capable of operating two helicopters. The ships were additionally outfitted with the launch and retrieval system for a set of five reconnaissance UAVs.
