Fighters are the basic fighting unit of AstroEmpires. Armed with lasers, they are unable to move between planets without a hangar unit.
Fighters are strong against unshielded units. Most fleets include fighters due to the low cost and low technological requirements. Fighters can be used for swarm attacks. They can also "soak up" enemy fire, reducing damage to more expensive ships.
Fighters are limited by an inability to travel between astros without hangar units. Low power makes them very weak against shielded units, except in large numbers or at a high laser technology level.
