An IrAero Sukhoi Superjet 100 at Irkutsk Airport

Number '34' visible on nose, signifying squadron/airframe code common in Russian service.

Known by the NATO reporting name 'Frogfoot.' Recognizable by underwing stores and straight wing shape.

The twin-engine, twin-tail configuration and thrust-vectoring characteristics are distinctive features of the Su-27.

The digital pixel camouflage scheme seen here is characteristic of Ukrainian Air Force Su-27s. The airframe cockpit, angle, and camo pattern are strong indicators.
