A carrier battle group (CVBG or CARBATGRU) or carrier strike group (CVSG) is a fleet of ships in support of an aircraft carrier. Such groups are primarily used by the United States Navy, which has 12 carrier battle groups scattered across the world. Their existence is an important part of the power projection capability of the United States in that they provide the ability to strike quickly almost anywhere in the world. The large number of CVBGs used by the United States reflects, in part, a division of labor allotted during the Cold War, in which the United States assumed primary responsibility for blue water operations and for safeguarding supply lines between the United States and Europe, while the NATO allies assumed responsibility for brown and green water operations.
Ships While an aircraft carrier has the ability to project a large amount of air power, it is vulnerable to attack from aircraft, submarines, and other surface ships. The primary role of the other ships in the battle group is to help protect the carrier from enemy air, surface, and submarine threats. The primary role of the carrier and its air wing is to provide the offensive firepower. These roles are not exclusive. Other ships in the battle group sometimes undertake offensive operations (launching cruise missiles, for instance) and the carrier's air wing contributes to the battle group's defense (through combat air patrols and airborne anti-submarine efforts). CVBGs have no definitive specification and are formed and dissolved on an ad-hoc basis, and one may be different from another. However, they all comprise similar types of ships, and a typical U.S. carrier battle group might include: The Carrier Battle Group (CVBG) could be employed in a variety of roles, most of which would involve the gaining and maintenance of sea control: History The CVBG was first used in World War II, primarily in conflicts between the United States and Japan in the Pacific. CVBGs at the time consisted of a far larger number of ships than current CVBGs, and this marked the only time CVBGs have fought each other, notably at the Battle of Midway. During the Cold War, the main role of the CVBG in case of conflict with the Soviet Union would have been to protect Atlantic supply routes between the United States and Europe. Because the Soviet Union had no large carriers of its own, a situation of duelling aircraft carriers would have been unlikely. The main scenario of interest would have been an attack against a CVBG using large number of anti-ship cruise missiles. The attempted use of anti-ship missiles against a carrier group was part of Argentina's efforts against Britain in the Falklands War. In addition, around the same time, the American navy recomissioned all four of its Iowa class battleships, and at times, used a similar formation centered around a battleship, referred to as a BBBG. In the late 20th and early 21st centuries, most of the uses of CVBGs by the United States have been in situations in which their use has been uncontested. The main scenario involving carriers coming under fire which is of interest to naval strategists has been a conflict between the United States and the People's Republic of China over the Republic of China (Taiwan). There is a consensus among observers that most of the military effort expended by the People's Liberation Army since the 1990s has been to at least complicate the deployment of a CVBG in a Taiwan straits conflict. Debate on future viability There is debate in naval warfare circles as to the viability of carrier battle groups in 21st century naval warfare. Proponents of the CVBG argue that it provides unmatched fire power and force projection capabilities. Opponents argue that CVBGs are increasingly vulnerable to arsenal ships and cruise missiles, especially those with supersonic flight and the ability to do radical trajectory changes to avoid anti-missile systems. It is also noted that that CVBGs were designed for Cold War scenarios, and are less useful in establishing control of areas close to shore. See also Modern naval tactics. | ||||||||
