The Myeong and Lyang MyL-23 (CDI reporting name: Frostbite) is a twin-seat, twin-engine variable-geometry carrier-capable fifth-generation all-weather carrier-capable fighter aircraft developed by the Myeong and Lyang Design Bureau. It uses advanced stealth technology in its design. It was designed primarily as an interceptor, air superiority fighter, but is able to perform many additional roles such as ground attack, electronic warfare, and signals intelligence making it a true multirole aircraft. All variants are designed to destroy aerial and surface targets with guided and unguided weapons at day and night under all-weather conditions in individual and group continental and maritime operations aimed at gaining air superiority and conducting air reconnaissance. The aircraft grew out of a need for Air force and Naval requirements for a new fighter design.

The Joint Next-Generation Tactical Fighter (JNTF) was a combination of the Naval Aviation's Advanced Navy Tactical Fighter (ANTF) program and the Air Force’s Experimental Heavy Fighter Program (XHFP) these programs were undertaken by the Anikatian Air Force and Naval Aviation to develop a next-generation heavy fighter interceptor and a air superiority fighter to counter emerging worldwide threats, including Arthuristan Spitfire, Emmerian F-31 and F-29 fighters under development in the 1990s. Myeong and Lyang Design Bureau and Kyzyma Aerospace were selected in 1992 to develop the model X-17 and the model Y-23 demonstrator aircraft. These aircraft were evaluated in 1995 and the Y-23 was selected and later developed into the MyL-23K.

History

In 1983, the Anikatian People's Air Force began forming requirements for a new heavy air interceptor fighter intended to replace the capability of the smaller lighter Ay-04 fighters. In November 1983 a request for information (RFI) for the Experimental Heavy Fighter Program (XHFP) was published by the Air Force. Design concepts were provided by defense contractors. The common areas among concepts were Stealth, STOL, high speed, high altitude, and supercruise. It was envisioned that the XHFP would incorporate emerging technologies including advanced alloys and composite material, advanced fly-by-wire flight control systems, higher power propulsion systems, and low-observable, or stealth technology. Before the program could advance beyond this stage it was combined with the Navy program. In January 1985 the Navy begun finalising its plans for first supercarrier, in response to emerging threats within the world. The Motykov class were seen as insufficient to defend and project Anikatia’s naval power. Thus with a new much larger more traditional aircraft carrier the need for a larger carrier capable aircraft to compliment the lightweight Ay-05 designs since the Ay-04s were already reaching the limits of their development potential and were fast becoming unable to face up against these emerging threats of stealth technology. In 1985 the Navy begun forming their own program called the Advanced Navy Tactical Fighter (ANTF) while similar to the Air Force requirement the navy called for carrier operations needing stronger landing gear, and slower landing speeds, weight would be a critical issue that the Air Force did not have any requirements regarding. However, the government saw potential cost issues of developing two distinct aircraft when there were so many similar requirements between the two programs.

Thus in 1986 the Air Force and Navy began combining their requirements under the Joint Next-Generation Tactical Fighter (JNTF) and another request for information (RFI) was issued July 1987 taking into account the new requirements from both forces. Following the first flight of the Arthuristan Spitfire in 1990 a new request for proposal (RFP) was issued by January 1992. It called for a carrier capable, two-seat, twin-engined air-to-air and some limited air to ground ability fighter with a maximum speed of Mach 2.5 or above, supercruise speed of Mach 1.0 or above, a mission radius of 1,400 km or above, maximum takeoff weight of no more than 29,000 kg. In May 1992, proposals by Nykov, Aymovski, Tubong, Myeong and Lyang, Yukimoh, and Kysunah. Two contractors, Myeong and Lyang Design Bureau and Kysunah Aerospace were selected in September 1992 to undertake a 25 month demonstration/validation phase, culminating in the flight test of two prototypes, the Y-23 and the Y-17. Under terms of agreements between Kysunah, Aymovski, and Nykov, the companies agreed to participate in the development jointly if only one company's design was selected. Myeong and Lyang, Tubong and Yukimoh had a similar agreement.

The first Y-23 made it’s maiden flight on 27 July 1995 and the first X-17 on the 29 August 1995. The first X-17 with DN Group engines supercruised at Mach 1.42 and the second Y-17 with Bulgakoh engines reached Mach 1.56. The Y-23 with DN Group engines achieved Mach 1.68 in supercruise and the second Y-23 with Bulgakoh engines reached Mach 1.57. Following flight testing, the contractor teams submitted proposals for JNTF production.

Following a review of the flight test results and proposals, the Air Force and Navy announced the Myeong and Lyang Y-23 with the DN Group engines as the competition winner on 23 March 1997. While Y-17 was far more agile, the Y-23 was more stealthy and faster. It was believed that the Y-23 with it's variable wing design was far better suited to the Naval requirements than the Y-17 design with featured a conventional wing layout.

Design

The MyL-23 was designed as both an air superiority fighter and a long-range naval interceptor. It features variable geometry wings that are controlled by the computer flight systems and automatically adjust to flight conditions reducing pilot load, although there is a manual override option. For high-speed stealth intercept, they are locked in a swept back configuration, they will swing forward for lower speed flight operations such as takeoffs and landings. The wing included leading edge slats and double slotted flaps over its full length. It was designed to improve on the Ay-04 interceptors air combat performance and on carriers complement smaller Ay-05 fighters.

The MyL-23's design and high performance engines allow it to climb faster than the older Ay-04s, or even power the Yuk-25 interceptors, while the twin-tail arrangement offers better stability. The twin engines are housed in nacelles, spaced apart by 1 to 3 ft (0.30 to 0.91 m). It was powered by two DN Group DF-41-S-400L turbofan engines with each in a separate engine nacelle on either side of the aircraft's spine. The wide spacing of the engines is used to store fuel and avionics systems such as the wing-sweep mechanism and flight controls. On the underside of the fuselage between the nose and main landing gear. The internal weapons bay can carry bombs, a removable 20 mm Esk-20-K1 autocannon, or auxiliary fuel tanks.

Variants

Y-23 ("Frostbite")
Initial preproduction prototype version used for JNTF testing and evaluation. Only one was built.
MyL-23A ("Frostbite-A")
A two-seat carrier-capable, pre-production evaluation testbeds.
MyL-23L ("Frostbite-B")
planned single-seat variant, this was a lighter land-based version of the with changes for the air force but was dropped in 1998 to save development costs. The MyL-23L was lighter via removing carrier landing capability. Only 2 built.
MyL-23K ("Frostbite-C")
A two-seat carrier-capable, production version, entered service in 2011.
MyL-23DKX ("Frostbite-D")
A two-seat carrier-capable, export version. It was originally given the designated MyL-23DKI originally but has been re-designated under the new systems as the current MyL-23DKX.
