When required, we must be able to respond with appropriate firepower from our carrier, surface, submarine and amphibious forces to take the battle to the enemy. Sea control is a fundamental function of the Navy and is defined as the ability to control designated areas in, over and under the sea as necessary to perform our mission. It does not necessarily mean permanent control of an entire ocean. Instead, it is selective, requiring that we control specific portions of the ocean whenever needed. We must be able to strike an enemy at sea and affect events ashore.
Power projection is the use of naval forces to launch strikes against the enemy.
It includes attacks by carrier aircraft, strikes by cruise missiles, amphibious assaults by embarked U.S. Marines, bombardment by naval gunfire, mine operations and landing of supplies and equipment by sealift vessels. Power projection is an offensive arm of operations which helps us to defeat the enemy on land. Balanced naval forces. Because of the many tasks the Navy must be able to accomplish, we require balanced forces. While some may be more necessary than others in specific situations, we need them all to perform our mission.
