As a Combat Systems Specialist (CSS) you work in a team to operate military radars and sonars, building a picture of the environment surrounding a warship. You locate, track and classify surface ships, submarines, aircraft and other contacts to inform action and engage threats using ship‑board and airborne weapons such as Phalanx CIWS, Typhoon, Mini‑Typhoon and remotely‑controlled weapon systems. You also direct maritime helicopters during search and rescue or anti‑submarine warfare operations.
