The Skira Sk.37 (Yuktobanian: Скира Ск.37; Osean reporting name: Flanker-B2; popularly nicknamed "Decimator-B") is a single-seat, twin-engine, supermaneuverable air superiority fighter, designed by the Sukhoi Design Bureau and built by the Sukhoi and Skira. It is a Compared to the older Skira Sk.27 that it improves on at a high cost, it has significantly improved maneuverability and two more hardpoints, but sacrifices all air-to-surface weapons except gun pods. The Sk.37 is a direct competitor to the Osean F/S-15 Eagle and F-15 S/MTD. The Sk.37 started as an internal development project in the Skira Sk.27. The design plan was revamped and the name was made official by the Yuktobanian Defense Ministry in 2002. Of the Skira Flanker family, the Sk.27, Sk.30, Sk.33, Sk.34 and Sk.35 have been ordered into limited or serial production by the Yuktobanian Defense Ministry.

Like the Sukhoi Su-37, the Sk.37 features canards, and thrust vectoring. In addition, it was modified with updated avionics and more weapons. The Sk.37 keeps the same weapons-control system from the Su-37, the N011M Bars (literally "Panther") pulse-Doppler phased-array radar, it provides the aircraft with simultaneous air-to-air and air-to-ground capability.

The Sk.37 carries the 23mm Gryazev-Shipunov GSh-23L instead of the 30mm GSh-30-1 on the Su-37, making it slightly lighter than Su-37 even it is slightly larger, it also helps the Sk.37 to overheat slower than the Su-37 by carrying smaller rounds. And smaller rounds makes it more accurate and have longer range than the 30mm.


Upgraded Sk.27[]

The first aircraft design to receive the Sk.37 designation had its origins in the early 2000s, at a time when the Sk.27 and Su-37 was being introduced into service with the Yuktobanian Armed Forces. The definitive production version of the Sk.27, which had the factory code of To-1G, started mass ("serial") production with the Komsomolsk-on-Amur Aircraft Production Association (KnAAPO) in 2003. The following year, this Sk.27 version reached initial operational readiness with the Yuktobanian Air Force. Having begun work on an upgraded Sk.27 variant in 1991, the Sukhoi Design Bureau was instructed in October 2001 by the Yuktobanian Council of Ministers to use the Sk.27 as the basis for the development of the Sk.27G (To-1G). Nikolav Nikolay would lead the design effort throughout much of the project's existence, under the oversight of General Director Mikhali Simov, who had been the chief designer of the Sk.27 along with Mikhail Pogsyan.

While sharing broadly the blended wing-body design of the Sk.27, the Sk.27G is visibly distinguished from the basic version by the addition of canards, which are small lifting surfaces, ahead of the wings. First tested in 2005 using an experimental aircraft, the canards, in complement with the reshaped wing leading-edge extension, redirected the airflow in such a way so as to eliminate buffeting at high angles of attack and allowed the airframe to sustain 10-g manoeuvres (as opposed to 9 g on the Sk.27) without the need for additional structural reinforcement. More importantly, when working with the relaxed-stability design and the accompanying fly-by-wire flight-control system, the aerodynamic layout improved the aircraft's manoeuvrability and enabled it to briefly fly with its nose past the vertical while maintaining forward momentum. Because of this, theoretically, during combat the pilot could pitch the Sk.27G up 120 degrees in under two seconds and fire missiles at the target. Other notable visible changes compared to the To-10G design included taller vertical tails, provisions for in-flight refuelling and the use of two-wheel nose undercarriage to support the heavier airframe.
