The Firespray-31-class patrol and attack craft, also known simply as a Firespray-class interceptor, was a patrol ship manufactured by Kuat Systems Engineering. Firesprays were used to guard and patrol the prison moon Oovo 4, while bounty hunters Jango Fett and Boba Fett piloted a customized Firespray named Slave I throughout their career, which Jango had stolen from Oovo IV.
