Why do fighter jets rarely fly at their advertised top speed? This video examines the engineering and combat tradeoffs behind the F-15 Eagle and F-35 Lightning II, explaining how fuel consumption, supersonic intake design, stealth, and maneuverability shape the speeds pilots actually use.
Follow the airflow through the engine intake to understand shock waves, variable intake ramps, and the F-35’s diverterless supersonic inlet—the smooth bump ahead of its intake. The explanation connects afterburner fuel demands with aerodynamic heating, radar-absorbing coatings, and infrared detection, showing why reaching a high Mach number and sustaining it are different challenges.
Project Red Baron’s analysis of Vietnam air combat provides context for corner velocity, turn radius, and John Boyd and Thomas Christie’s energy-maneuverability theory. The video explores why speed can widen a fighter’s turning circle, while short supersonic bursts remain useful for repositioning and missile launches. The SR-71 Blackbird provides a comparison with an aircraft designed for sustained high-speed reconnaissance.
