Gunstar
A Gunstar is a heavy starfighter employed by the Star League in the movie The Last Starfighter.
Specifications
A Gunstar is a two-seat starfighter operated by a navigator who pilots the vehicle and a "starfighter" who operates the weapons. A Gunstar is heavily armed with beam weapons and missiles, although the exact payload wasn't specified. Gunstars have four engines for sublight propulsion, and they are capable of at least some FTL travel. The Gunstar's beam weapons are located in multiple turrets around the vessel give it the ability to attack any enemy ship nearby it with almost all of it's weapons meaning that there is no safe direction to approach the ship from. It's missiles, while only launching forward, can target and hit targets from any direction. The only way to effectively attack a Gunstar is to overwhelm it with targets.
Threat Assessment
The Kodan Armada considered Gunstars so superior to their own ships and fighters that they deemed a single Gunstar to be a serious threat to their invasion of the Star League, and they would not have invaded had not a traitor assured them that he could destroy the entire Gunstar fleet in its hangar and assassinate all of the crews.
How Gunstars would compare to the starfighters and warships of other settings is difficult to determine.
