The Su-35S, a highly agile 4++ generation fighter, reportedly achieved a remarkable increase in range due to a deliberate reconfiguration of its internal fuel storage. This improvement has been highlighted by Rostec, the state corporation overseeing defense ventures.
According to the government agency, the aircraft demonstrated a record range exceeding 3,500 kilometers. The optimization comes from strategically placing fuel tanks within the fuselage and along the wing consoles, a layout that minimizes drag while maximizing flight endurance.
Addressing concerns about fuel movement under high g-loads, engineers implemented a sponge-like polyurethane foam that stabilizes kerosene during aggressive maneuvers. This solution reduces the risk of fuel shifting and ensures reliable engine performance under stress.
Rostec also noted that the Su-35S aligns with fifth-generation fighter characteristics across most of its performance metrics. The AL-41F-1S powerplant is capable of achieving near-supersonic speeds without a full afterburner, thanks to efficient engine management and advanced propulsion control.
In related developments, Russia reportedly introduced a new drone suppression system designed to counter hostile unmanned aerial vehicles and protect critical airspace assets. This system complements the Su-35S platform by broadening the defensive capabilities of modern air fleets.
