# Base Speed

316pages on
this wiki

The original speed that a ship travels. The speed and distance decides the travel time between planets. Ship speed is increased above base with every level of engine researched.

• Combustion Drive increases the speed of ships using a combustion engine by 10% of base for each level researched.
• Impulse Drive increases the speed of ships using impulse engines by 20% of base for each level researched.
• Hyperspace Drive increases the speed of ships using hyperspace engines by 30% of base for each level researched.

* Small Cargo Ships start out with a combustion engine. Once Level 5 Impulse Drive is researched, all Small Cargo Ships are automatically upgraded to Impulse engines and take advantage of the faster speed.
** Bombers start out with an impulse engine. Once Level 8 Hyperspace Drive is researched, all Bombers are automatically upgraded to Hyperspace Engines and take advantage of the faster speed. *** Recyclers start out with an combustion engine. Once Level 17 Impulse Drive is researched, all Recyclers are automatically upgraded to Impulse Engines and take advantage of the faster speed. ****Once Level 15 Hyperspace Drive is researched, all Recyclers are automatically upgraded to Hyperspace Engines and take advantage of the faster speed.

Duration of Flight

$T=10 + 3500\sqrt{\frac{10\cdot D}{V}}$


$T$ is the flight time of the fleet in seconds, where $D$ is the flight distance as calculated above and $V$ is the speed of the slowest ship in the fleet. Divide the above with the speed factor you have chosen. Please note that due to rounding there might be a small discrepancy between $T$ and "duration of flight" displayed.
