The Protector-class corvette is a vessel used primarily to protect internal trade routes in the Nivenian Empire. Perhaps the most numerous ship in the Nivenian Navy, they are the only ships that typically do not participate in national wars, and they are also the only ship to work closely with the security forces of the various corporations within the Nivenian Empire. Their main purpose in battle is the usage of missiles and flak artillery to intercept would-be pirates and prevent missiles from reaching trade ships.

While the ship is almost invulnerable to plasma weapons, and has a strong defense against kinetics, it is weak against lasers and electron beans. Due to the nature of this ship's role in combat, it is unlikely that two of these would ever fight each other head-to-head. Still these ships are usually taken out by imparting massive amounts of momentum through thermonuclear bombardment until the crew of the ship is killed from the massive accelerations.
