 Also new was the fire-control system, at the heart of which is the N011 pulse-Doppler radar, which could track up to 15 aerial targets simultaneously and guide up to six missiles simultaneously. The tail "stinger" houses the Phazotron N-012 rear-facing radar. The aircraft could carry various bombs (including napalm, dumb and Cluster munitions) and both air-to-air and air-to-surface missiles; and had two additional underwing pylons. The cockpit was modernized, equipped with multi-function colour LCD screens, and fitted with a K-36DM ejection seat inclined at 30°to improve pilot g-force tolerance. Range was increased to 4,000 km (2,222 nmi), the adoption of an aerial refuelling probe enables further range extension. The aircraft was characterized by its twin nose wheel – as a result of higher payload – and larger tail fins with Carbon-fiber-reinforced polymer square-topped tips.
