The Mheadhain-class vessels are a series of patrol vessels designed and produced by Pereda Construción Naval Consolidada of Temuair for the Imperial Navy of Temuair. The Mheadhain-class first entered service in 1988, and its newest version, the Mheadhain III-class, is currently in service with the Imperial Navy. These vessels are designed for high speed, high-maneuver operations within the nation's littoral zone. The Mheadhain-class is highly capable in shallow wasters due to its advanced thrust vectoring controls.
Mheadhain-class
The Mheadhain-class first entered service with the Imperial Navy in 1988.
Though the original plan was to equip the Mheadhain-class with the Srad CA.301 30 mm automatic cannon, it was not yet ready for production when the Mheadhain -class was approved. The Dnieguan EfKan m/38 20 mm cannon was chosen instead. In addition, both light or heavy machine guns can be fitted, depending on the vessels intended mission
Mheadhain II-class
The Mheadhain II-class entered service with the Imperial Navy starting in 1996, and completely replaced the original Mheadhain-class vessels by 2012.
The vessels also saw a significant increase in top speed, increasing from a maximum of 37 knots to 52 knots. The vessel has a marine aluminum alloy planing hull in order to maintaining high standards of sea-keeping, maneuverability and static/dynamic intact/damaged stability in adverse environments.
The Mheadhain II-class is equipped with the lightweight 30 mm Srad CA.301 automatic cannon on a lightweight stabilized platform. The cannon can be operated independently, or slaved to the vessels mast-mounted electro-optical targeting system, which is capable of day or night operations in any sea state. The vessel also retained its mountings for light or heavy machine guns, as well as automatic grenade launchers.
Mheadhain III-class
The Mheadhain III-class entered service in 2010, and is in the process of replacving the Mheadhain II-class vessels in service. It features refinements to the hull design to allow the vessels to reach and maintain high operating tempos. Its hull geometry provides constant sea keeping at all speeds, and a dry deck throughout high-speed runs. The advanced HydroDrive-2000 thrust-vectoring propulsion system allows vessel to function in shallow waters at draughts of 1.2 metres (3.9 ft) facilitating special operations forces delivery on enemy shores and catastrophe relief missions.
The vessels are equipped with a variety of electronic systems including radar targeting and warning systems, as well as intelligence gathering systems and self-defense suite which includes chaff and flare dispensing equipment.
The Mheadhain III-class retained the armament options of the predecessor, but also incorporated a four tube surface to surface missile launcher for engaging coastal targets and light vessels. Currently, the vessels are equipped to fire the Areiva Puñal anti-tank missiles, which is effective against a variety of targets. All weapons systems can be operated independently or remote controlled from the vessels command center, and slaved to the vessels mast-mounted electro-optical targeting system, which is capable of day or night operations in any sea state.
