This was a concept model of a Martian ship for one of my old story ideas. It was the Martian equivalent of an F-22 Raptor, designed for space and atmospheric combat. Not visible on the model are two Pulser cannons, which can be aimed straight ahead for dogfights or angled downward for ground bombardment. The lime glass sections represent the vehicle's anti-gravity turbines, which generate a field of anti-gravity around the ship, allowing it to move in all directions, like a VTOL.
