The Carrier Battle Group

First, it is important to note that there really is no real definition of a battle group. Battle groups are formed and disestablished on an as needed basis, and one may be different from another. However, they all are comprised of similar types of ships. Typically a carrier battle group might have:

• a carrier – The carrier provides a wide range of options to the U.S. government from simply showing the flag to attacks on airborne, afloat and ashore targets. Because carriers operate in international waters, its aircraft do not need to secure landing rights on foreign soil. These ships also engage in sustained operations in support of other forces.
• two guided missile cruisers – multi-mission surface combatants. Equipped with Tomahawks for long-range strike capability.
• a guided missile destroyer – multi-mission suface combatant, used primarily for anti-air warfare (AAW)
• a destroyer – primarily for anti-submarine warfare (ASW)
• a frigate – primarily for anti-submarine warfare (ASW)
• two attack submarines – in a direct support role seeking out and destroying hostile surface ships and submarines
• a combined ammunition, oiler, and supply ship – provides logistic support enabling the Navy's forward presence: on station, ready to respond

The Carrier Battle Group (CVBG) could be employed in a variety of roles, all of which would involve the gaining and maintenance of sea control:

• Protection of economic and/or military shipping.
• Protection of a Marine amphibious force while enroute to, and upon arrival in, an amphibious objective area.
• Establishing a naval presence in support of national interests.
