When a fighter jet needs to accelerate instantly and efficiency is completely abandoned, they just dump unburnt fuel directly into the superheated exhaust stream. This is called an afterburner. Since jet exhaust still contains unused oxygen, the raw fuel ignites immediately, creating a secondary explosion that forcefully expands the gases. It heavily increases thrust while simultaneously chugging fuel fast enough to drain the tanks in minutes.
