For player use, the ISS Gunboat is capable of using an Afterburner, Antimatter Reactor, and two Targeting Unit-assisted Small Tachyon Beams, that can make it very powerful.
- Non-veterans use two Laser Cannons and are very lightly armoured. Hardly dangerous.
- Veterans have a Tractor Beam, an Energy Siphon, a Vampiric Ray, and an AI-only Vampiric Ray M2. Strong foes at close range.
- Double Veterans use dual Targeting Unit-assisted Small Tachyon Beams. They should be attacked with caution; ranged weapons such as the railgun help to kill them.
- A Gunboat in real life is a small and maneuverable ship designed to carry one or more guns for coastal bombardment, or to ferry troops and supplies to shore.
