GeoCalibur looks very much like it's relative. The GeoSword. It has a cockpit and a gunners seat. It has the same fins, design, and shape as GeoSword. It has the same underside double-barreled canon as GeoSword, but with another one attached at the top. The weapon system has a different operating mechanism than that of GeoSword though as they act as an automatic weapon. The weapons fire faster than GeoSword though they aren't as powerful.
- In StarBlade: Operation Blue Planet the form of GeoCalibur is never really seen.
