The carrier remains one task unit even though it performs several functions for the group. Its roles include strike aviation, air defence, airborne early warning, extra helicopters for anti-submarine warfare, and probably search and rescue. A Type 45 destroyer has a narrower primary task: stopping air attacks that penetrate the outer defensive line. Its helicopter can also support surface patrol and anti-submarine work. Ships with very different ranges of responsibility can occupy the same level in the organizational hierarchy.
