Speed

Oversized Thrusters Tier 1
It's simple: bigger thrusters equals faster ship speed, at the cost of higher power use.

Ship: Increased Speed Research: Optimized Catalyst Scrambler

Optimized Catalyst Scrambler Tier 2
Optimizing the thruster scrambler to better use the catalyst gives a cleaner burn, increasing ship speed.

Unlocks
Ship: Increased Speed Research: Vectored Thruster Upgrade

Vectored Thruster Upgrade Tier 3
Adding mechanical vectoring to the main ship engine gives the ability to turn much sharper, as well as angling thrust to the exact vector required - speeding up the ship immensely.

Ship: Increased Speed Research: Oversized TurboJets Research: Turret Fire Control Research: Quantum Ship Fuel

Quantum Ship Fuel Tier 4
Passing the ship fuel through a quantum filter increases the usable energy potential - pushing the speed limits of the ship to the maximum.
