How the Su-30MKI flies up to 8,000 kilometres using mid-air refueling
The Su-30MKI extends its 3,000-kilometre base range to 8,000 kilometres using mid-air refuelling. By connecting to Il-78MKI tankers, the jet safely sustains 10-hour flights for combat missions.
3,000 Kilometre Base Range
The Su-30MKI possesses a large internal fuel capacity that provides a standard unrefuelled flight range of 3,000 kilometres. To execute deep penetration strikes or long border patrols, the fighter relies on mid-air refuelling to stay airborne much longer.
1 Retractable Refuelling Probe
To receive fuel mid-air, the fighter is equipped with one retractable refuelling probe located directly in front of the cockpit. When approaching a tanker, the pilot extends this probe to securely connect with the fuel hose while flying at high speeds.
Connecting To Il-78MKI Tankers
The Indian Air Force primarily uses Ilyushin Il-78MKI tanker aircraft to supply aviation fuel during extended combat missions. The tanker extends a specialised drogue hose, allowing the fighter jet to safely dock and receive thousands of litres of fuel.
Sustaining 10 Hour Flights
Receiving aviation fuel without landing reduces pilot fatigue and increases overall mission efficiency. With consistent aerial refuelling support, the heavy twin-engine fighter can safely remain airborne and fully operational for 10 hours at a stretch.
8,000 Kilometre Maximum Reach
With the assistance of just two in-flight refuellings, the maximum operational range of the Su-30MKI expands to 8,000 kilometres. This strategic capability allows the Indian Air Force to project tactical aerial power far beyond national borders.
