Airspeeders depend on gravity-control technology to fly in both planetary atmospheres and in outer space. An airspeeder tends to be very fast in both environments.
Larger spaceships which are too big to land on planets and moons rely on airspeeders.
Very few airspeeders are equipped with Hyperdrive of their own, and so rely on larger ships equipped with hyperdrive to travel interstellar distances faster than light.
Starfighters are a sub-class of airspeeder.
Airspeeders are generally from 10 to 25 feet long.
