The Motyekkoyu-class (Anikatian: 뫁옠오유) is the main aircraft carrier of the Anikatian Navy Forces. It was conceived and designed in the 1960s as a replacement for the Gwokkantya light carriers which was the flagship of the newly independent Anikatian state. This was the nation's first attempt at building an aircraft carrier. while considered a small carrier by international standards it was still far larger than the carriers it replaced . It did not follow the traditional standards instead follows a mixed cruiser carrier design. Following the collapse of the socialist regime this carrier design has been successfully exported through the Anikatian International Trade and Export Corporation (ANKITEC).

History and development

The new DSRA People's Navy lacked a substantial naval aviation force, instead relying on outdated and rapidly ageing Gwokkantya light carriers, acquired during the Great Eastern War. After the end of the civil war the new naval command objectives required the development of a full-fledged aircraft carrier to expand and vastly improve the navy's operational force projection. Initially, the new design was envisaged as a low cost multirole 50,000-60,000 tons conventionally powered aircraft carrier. The first new naval aircraft carrying ships of the DSRA was the Taesun-class helicopter carrier. Even during its construction, work began on the new project for the development of a universal aircraft carrier.

In response to the requirements set out by the there were several arrangements considered. Including a smaller VTOL aircraft and rotorcraft layout, a significantly larger design with a traditional fixed wing layout with a nuclear power plant. Ultimately a smaller, cheaper and less risky conventional powered design with a traditional fixed wing layout was chosen for production. While the design was set up much like a conventional aircraft carrier with an air deck on the port side and aft and superstructure shifted to starboard it was however far more heavily armed than the Western equivalent designs. The construction of ships of this size, while adapting to modern naval aviation, involved overcoming an unprecedented number of challenges for Anikatian shipbuilding. The technical project was approved by the DSRA Ministry of Defence, Ministry of Shipping and other organisations.

The ships were initially constructed in the shipyard of Seoeunju, Ulsanghae, While a new shipyard was constructed in Anjul, Akyannya this allowed for concurrent production from Akyannya subclass onwards. The manufacturing process was completed via prefabricated sections, a technology which sped up the construction process. The Keel for the construction of the first ship of the series, which was given the name "Motyekkoyu" (뫁옠오유) put on July 1972. The vessel was launched in April 1977, Before being entering service, Motyekkoyu passed acceptance tests and naval trials. It was during this time that it the first Ay-04 fighter aircraft were tested on the ship, it was demonstrated to the Minister of Defence and other high officials. The ship completed the first stage of tests and was taken by the state committee on December 1979, it entered service with Anikatian People's Navy, although some further adjustments and minor improvements had to be made before the vessel was accepted by the navy. However, over it's long service life numerous redesigns, upgrades and further development changes were implemented. They formed the bulk of the DSRA's ocean-going force projection until the larger Albyekreu class aircraft carriers were built.

Evolution

The Motyekkoyu and second of her class Pyongtya were fitted with a steam turbine system which generated 130,000 kW (174,334 hp). However following the new governments review of the vessel. Numerous changes were implemented and led to the new Akyannya subclass, these featured an updated and increased armaments, improved and more powerful steam turbines generated 134,000 kW (179,697 hp) which allowed the vessel to reach flank speeds of 31 knots (57 km/h). While the designs of the final seven ships (beginning with ANV Byeuksun) are slightly different from those of the earlier ships, the Anikatian Navy considers all the carriers as a single class. These later vessels of the Byeuksun subclass feature noteworthy technological advances. Changes from the previous Motyekkoyu design include: CODOG propulsion, all-electric auxiliaries, an advanced machinery control system including throttle control from the bridge, water mist fire protection systems. It is suspected that at least one vessel may have been outfitted with a nuclear reactor for trials to provide data that would feed into the development of the full size nuclear Albyekreu class aircraft carriers then underdevelopment. During refits and modernisation earlier vessels were brought up to the armament standards of the Byeuksun subclass. which has further modernisation the carriers by removal of the SV-070M Gyrnta anti-ship missiles, to provide greater hangar and fuel storage space along with update of the SQ-034MK Toryu-K SAM system and SQ-130M2 30mm CIWS.

Air Wing

Operating as the main stray of the naval aircraft projection power it has operated a large number of aircraft in its service life, the main tactical aircrafts flown by the Motyekkoyu carriers were Ay-04 variable sweep wing fighter-bombers, Ay-05 multirole fighters, most recently the Ay-105 stealth fighters. MyL-23 heavy multirole interceptors initially thought too heavy to operate from the carrier have achieve success in testing. Helicopters, VTOL and auxiliary aircraft operated on the Motyekkoyu consist of Tsk-14 multirole medium helicopters, Tsk-18 VTOL for logistics; transports and IV-62EW is used for airborne early warning.

Exports

While this type was exported in limited numbers during the period of the DSRA, it was only provided to the closest most trusted allies of the regime. Since its collapse of the DSRA in 2001 and subsequent opening of its markets along with the creation of Anikatian International Trade and Export Corporation (ANKITEC), it has once again been an export product.

Temuair

A 2014 review indicated that Kystia was surplus to operational requirements and she was offered to the Imperial Navy of Temuair. In 2015, Kystia took part in a combined exercise with the Imperial Navy of Temuair, during which the carrier was visited by senior Imperial Navy of Temuair officers and Anikatian government officials, while Temuair Ay-05 Fragors practised landings on the carrier. The offer was made to sell Kystia and a squadron of Ay-05NGs to Temuair. However, instead of being decommissioned, the carrier was immediately transferred to the Imperial Navy of Temuair where she continues to serve as Ceannlaidir, the only aircraft carrier currently serving in Temuair.
