The Trimaxion Drone Ship is a spacecraft that appeared in the movie, Flight of the Navigator, commanded by the AI computer Max, from the planet Phaelon.
The ship is silvery chrome in color. It usually has a shell-like appearance, but when needed, it can change its shape into a somewhat arrow shape for its First Class Manuever. It is also capable of traveling underwater.
It is equipped with a faster than light drive of an undisclosed nature and time travel function, allowing Max to return samples exactly as found without a second missing in-between abduction and return. This means he does not disturb the environment he came to observe.
