How Fighter Jets Fight
Move past cinematic dogfight myths to understand how modern fighter aircraft actually wage air combat. Learn how pilots manage energy-maneuverability, defeat incoming missiles using pure geometry, and execute lethal beyond-visual-range radar intercepts.
Like Duolingo, but for How Fighter Jets Fight. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Winning the Close-Range Dogfight and Dominating the Beyond-Visual-Range Arena. It assumes you already know the basics.

Key ideas in How Fighter Jets Fight
- Positive Ps means engine thrust exceeds total drag at the current G-load.
- With surplus energy, a fighter can climb or accelerate while turning.
- Negative Ps forces a pilot to lose speed or altitude to sustain the turn.
- Corner airspeed sits right at aerodynamic lift and airframe G limits.
- Above corner speed, structural G-limits force a wider turning circle.
- Below corner speed, the fighter stalls before reaching maximum G.
- In a one-circle fight, both jets turn toward the same side into each other.
- Two-circle fights turn away from each other and reward pure turn rate.
- Tighter radius wins one-circle, while higher degrees-per-second wins two.
- Pitching up trades forward airspeed for altitude, reducing closure rate.
- Gravity assists the fighter's nose rotation back down toward the target.
- Diving back down trades potential energy back into pursuit speed.
- HOBS missiles allow lock-on well outside the fighter's direct nose line.
- Helmet sights let pilots cue seeker heads simply by turning their head.
- Lethal snapshot envelopes make entering prolonged turning fights risky.
- Head-on target closure adds combined speeds, greatly extending the missile's unpowered reach
