The v-90 Protector, a product of Kuat Drive Yards, represented a specific ion cannon design intended for safeguarding planets. As one of the three well-regarded models within KDY's v-series, this medium ion cannon possessed the ability to engage targets from the ground up to low orbit, proving effective against capital ships. It was frequently deployed as a defensive armament to protect numerous fortified locations. While a full crew of ten was optimal for operation, the Protector could function with a minimal crew of four.
