of multiple MiG-29KUB aircraft for AEW coverage. The MiG-29KUB may also be enhanced in areas such as electronic warfare and long-range interdiction. The MiG-29KUB two-seat variant took its first flight on 20 January 2007, followed by the MiG-29K on 25 June 2007. Design The MiG-29K is drastically modified from the Mikoyan MiG-29M for naval operations. The airframe and undercarriage are reinforced to withstand the stress experienced upon landing. Folding wings, an arrestor hook, and catapult attachments were added for carrier operations; the aircraft's undercarriage track was also widened. The MiG-29K, unlike the early MiG-29, can both conduct aerial refueling and "buddy" refuel other aircraft. The MiG-29K has two widely spaced RD-33MKs. The early prototypes were fitted with two RD-33K turbofan engines, each with afterburner thrust of 86.3 kN (19,800 lb) and a possible take-off thrust of 92.2 kN (20,723 lbf) for shipborne operations. The RD-33MK engine features 7% higher power over the base RD-33, enabled by the usage of improved materials for the turbine blades. Internal fuel was increased from , to give a combat radius of 850 km (531 mi). The combat radius can be increased to with three underwing fuel drop tanks. The maximum weight of the aircraft grew from , to allow for increased payloads. The MiG-29KUB two-seat fighter, intended for pilot training, can also conduct combat missions identical to the single-seat fighter. Cockpit and avionics The aircraft is equipped with three multifunctional color liquid-crystal displays (seven LCDs on the MiG-29KUB), a four-channel digital fly-by-wire flight control system, passive homing system for anti-radar missiles, Sigma-95 GPS receiver, TopGun helmet-mounted targeting system and electronic countermeasures (ECM). Additionally, an onboard oxygen generating system eliminates the need for heavy oxygen canisters. The types of combat missions undertaken by the MiG-29K can be increased by adding optronic/infrared imaging reconnaissance pods. The Zhuk-ME is a development of the N010 Zhuk radar, introducing functions such as terrain mapping and following. The radar, weighing , features improved signal processing and a detection range of up to vs a 5 m2 RCS target for the export variant. In the air targeting mode, up to ten targets can be tracked and four targets engaged simultaneously. In air to surface mode the radar can detect a tank from up to away and a bridge from away, a naval destroyer could be detected up to away, while up to two surface targets can be tracked at once. The
