Vetrov-Kazakov VeK-44

The Vetrov and Kazakov VeK-44 (Stasnovan: Ветров-Казаков ВеК-44) is a Stasnovan canard delta wing, twin-tailed, 4.5-generation generation air superiority multi-role all-weather tactical fighter utilising stealth technology developed by the Vetrov-and-Kazakov Design Bureau during the 90s and entered service with the Stasnovan Revolutionary Air Force in 2006.

Origins and development
The 90s brought a new type of fighter into play; the stealth fighter. The Stasnovan VVS had no fighter of such type in its arsenal, though several experimental projects existed since the 80s. However, expensive fighters were against the Stasnovan doctrine of cheap, reliable, mass produced while capable aircraft. As years passed however, the Stasnovan leadership saw that if they wouldn't develop a fighter of their own, they would be left behind in a new arms race. Thusly, funding was granted to the Vetrov-Kazakov and Lyukov Design Bureaus to begin the development of an advanced multi-role fighter with stealth characteristics.

Airframe
The airframe of the VeK-44 is a canard delta wing, twin-tailed design, utilising some stealth characteristics. The delta wing design provides a high stall angle, and is also much more simple and cheap when comparared to conventional designs. The canards allow for significantly lower minimum landing and flight speeds, enabling the VeK-44 to operate from both standard and STOBAR aircraft carriers without the need for modifications. The canards also have a leading-edge sweep of 58° and a prominent dogtooth which improve airflow over the wings at high alpha (angles of attack). Meanwhile, the delta wings have a wing leading edge sweep of 52°. The VeK-44 airframe makes extended use of aluminum-lithium and steel and titanium alloys, and composites. The airframe's unconventional design increases the aircraft's maneuverability, however, it makes it almost impossible to fly without fly-by-wire (VeK-44A) or fly-by-optics (VeK-44M) systems to make it controllable.

Stealth
The nozzle's inner petals were lined with ceramic tiles to reduce infrared signature. Active cooling of the exhaust gas emitted by the VeK-44 Krasna AL-50M afterburning turbofan engines also significantly reduces the infrared signature of the aircraft. The unorthodox design, use of radar-absorbent materials (RAM), and internally mounted weapons, give it a very effective RCS.

Engines
The VeK-29s uses the Krasna AL-50M afterburning turbofan engines, vector thrusting in three dimension, which is an improved version of the AL-41, which were originally used on the original VeK-44A. The AL-50M provides the aircraft with a maximum speed of Mach 2.5. The AL-50M also provides the ability to the VeK-44 to supercruise at Mach 2.24.

Electronics and Avionics
The original VeK-44A used the Irbis-E multi-mode, hybrid passive electronically scanned array. Meanwhile, he VeK-44M main sensor system is the N040 Nalka advanced active electronically scanned array radar. The N040 consists of the main nose-mounted N040-1-01 X band AESA Radar and two side-looking N040 B-1-01 X-band AESA radars embedded in the cheeks of the forward fuselage for increased angular coverage. The suite also has two N040L-1-01 L band arrays on the wing's leading edge extensions that are not only used to handle the N040Sh friend-or-foe identification system but also for electronic warfare purposes. When working in concert with one another, the system provides the VeK-44 an azimuth of 360°.

The VeK-44M also features the ESRA-M1 electro-optical Distributed Aperture System (DAS). The ESRA-M1 is a multifunctional missile warning, ultraviolet and infra-red search-and-tracking, missile reporting and aircraft detection system, that consists of multiple, infra-red, ultraviolet and electro-optical sensors in such a way as to provide unobstructed spherical coverage and functions around the aircraft without any pilot input or aiming required.

Stasno-Dagelian War
VeK-44M were used both in interdictor/strike and air superiority roles during the conflict. In the first initial aerial face of Operation Kogot (the rapid deployment of Stasnovan troops to Dagelia), VeK-44M provided top cover for strike groups of Lu-24M2s and Lu-34s.

On the second day of operations, a strike formation was jumped by four Dagelian ViS-60Bis fighter-interceptors. A flight of five VeK-44M broke formation and engaged the ViS-60s, shooting three of them down with K-77M medium-range missiles, while the remaining Dagelian fighter turned about and left the area of operations. These were the first official air-to-air kill of the VeK-44 against a fixed-wing aircraft.

Other air-to-air kills by VeKs were 2 Lu-22M4, 2 ViS-70MLs, 1 Lu-25KM, 1 Si-24P, 1 Si-17 and 1 Ye-28. One VeK-44M flown by Major Ilya V. Nikarov was damaged by 9K37 Buk surface-to-air missile system, when the projectile exploded several feet away from the left wing. The VeK-44M succesful returned to base, though its left landing gear leg broke on the landing process, resulting in the aircraft's left wing getting ripped from the plane. The aircraft was later repaired and returned to service.
