An arsenal ship is a naval concept for a warship intended to serve as a floating missile launcher platform with as many as five hundred vertical launch bays for large-sized guided missiles, most likely cruise missiles. In current U.S. naval thinking, such a ship would initially be controlled manually by an Aegis Cruiser, although plans that have long since been scrapped included control by AEW&C aircraft such as the E-2 Hawkeye and E-3 Sentry.
