Speed

Speed is a number used to determine how fast a ship travels.

Base Speed and Effective Speed

Each ship in Starfleet Commander has a Base Speed, which is the speed it will travel at if its engines have not been upgraded through researched technologies.

Jet Drive, Pulse Drive, and Warp Drive research all increase the speed of ships powered by those drives by 10%, 20%, and 30%, respectively. The increased speed as a result of the engine upgrades is called the Effective Speed.

Example:

A Poseidon Class has a base speed of 15,000. It also has a Pulse Engine and requires Level 4 of that to be built. Pulse Engine Tech gives a speed boost of 20% for each level, so in this case 80%. Thus a Poseidon's Effective Speed is 1.8 * 15,000 = 27,000

Any fleet travels at the speed of the slowest ship in that fleet. Therefore if you send out an attacking fleet containing some Poseidon Class ships and some Hercules Class ships, the fleet will travel at the much slower speed of the Hercules Class.

Travel Times

The time it takes, in hours, to travel from one planet to another is equal to the Distance divided by the fleet's speed.
