One thing to note, the Monofan isn't a Jet Fighter, it's a Fan Fighter. That's a high performance electric Ducted Fan propelling it. Power is supplied by a Fuel Cell running on compressed natural gas.

Of course, since it's fuel is flammable, all you need are additional fuel lines and an ignition system to give it an afterburner. 50% more thrust when active. Unfortunately it also increases fuel usage by150%.
