Armada 1 Scout
The game Star Trek: Armada has four kinds of ships, that can be considered a scout:
Together with the destroyers they are the fastest ships of the game. They require only small amounts of resources but are generally really weak as actual attacking or defending units. Their large scanning range of 800 is only second to sensor stations. Together with the researchable Tachyon Detection Grid they are the ideal scouting ship.
Depending on the used Techtree the ship may already come with the Tachyon Detection Grid from the beginning. Scouts are available right from the start at the tier 1 yards.
