control systems (WCSs). A vertical launching control systems (WCSs). A vertical launching system (VLS) accommodates missile stowage and system (VLS) accommodates missile stowage and launch on ships. On all attack submarines, launch on ships. On all attack submarines, missiles are launched from torpedo tubes (with missiles are launched from torpedo tubes (with stowage in the torpedo room); in addition, some stowage in the torpedo room); in addition, some attack submarines have VLS located forward, attack submarines have VLS located forward, external to the pressure hull, which will handle external to the pressure hull, which will handle both stowage and launch. both stowage and launch.

The Fire Control Systems (FCS) on both ships The Fire Control Systems (FCS) on both ships and submarines perform communications and submarines perform communications management, database management, management, database management, engagement planning, and launch control engagement planning, and launch control functions. These systems provide the interface functions. These systems provide the interface between the missile and FCS for missile between the missile and FCS for missile initialization and launch as well as environmental initialization and launch as well as environmental protection. protection.
