Drone Speed

Oversized TurboJets Tier 1
By simply adding a larger turbojet to each drone, speeds can be increased significantly. Care is taken to ensure the power drain remains the same.

Drones: Higher Speed Research: Rotary PowerTrain

Rotary PowerTrain Tier 2
Advances in unmanned vehicle powertrains filter down to automated drones - the rotary motor reduces weight and increases power, allowing even greater speeds for drones.

Drones: Higher Speed Research: Fusion Elimination Circuit

Fusion Elimination Circuit Tier 3
Scavenging the kinetic power lost in the turbine combined with the thermal power lost in the exhaust, engine efficiency can be increased up to record levels - allowing the drone to push it's speed limits even further.

Drones: Higher Speed Research: Quantum Fuel

Quantum Fuel Tier 4
Sure, passing fuel through a quantum field before igniting it in a fusion chamber might sound risky - but it gets the job done. This gives drones the fastest speed ever.
