Starfighter
Starfighters are vehicles commonly found in science fiction. Usually having a single pilot, armed with guided and unguided weaponry, agile and fast, they are the science fiction equivalent to modern-day jet fighters.
Practicality
As was discussed at Atomic Rocket and at this Stardestroyer.net thread, starfighters are probably not a logical vehicle to use in space combat, as they have no real advantages that a larger ship doesn't already have.
