This is just made up off the cuff so don't bash it too hard.
Perseverance-class interplanetary exploration vehicle.
Length: 593 ft.
Width: 320 ft.
Height(without landing gear): 100 ft.
Powerplant: Sustained Fusion reactor(needs to be refueled every two years).
Speed: 0.409c(slower when in mediums other than a vacuum)
Propulsion: Twelve+ gravity field projectors/manipulators(these also provide inertial dampening and earth-like gravity for the ship).
Sensor array: Is composed of optical(view over 99% of the spectrum), radiation(virtually anything thats radiated is detected), subspace(very primitive and virtually incapable of detecting anyhting in subspace or hyperspace that isn't at least the size of a large city).
Shields: intense gravity fields geared to move objects around the ship.
It was developed and built in secret by a group of scientists that had no connection with or affiliation with the stargate program or alien races. It was meant to explore the solar system in its entirety(as well as putting other's experiments into space). It was designed to operate in virtually any large medium(except for underground) including underwater.
I hope this is interesting for you guys/girls.
