Corvette's detailed below are the smallest class of warship in a modern fleet. Often used as coastal or littoral combat vessels, the Corvette can defend shallow water areas against surface vessel and submarine incursion. Equipped with radar and sonar technologies, these naval units will be very useful in the defense of your coastal provinces in anticipation of a fleet approach.
