They're talking about this prototype doing mach 0.7, so it's a safe bet they intend it to have a turbofan. That's much faster than a MQ-1/MQ-9 and also faster than a (turbofan) MQ-20. Dismissing this design because it requires a jet engine just seems bizarre. Like okay, it doesn't work with piston props... so what?
