Strike groups comprise a principal element of U.S. power projection capability;[3][4] a single supercarrier holds enough firepower to rival the air forces of entire nations.
[5] The carrier strike group is a flexible naval force that can operate in confined waters or in the open ocean, during day and night, in all weather conditions.
Thus, from a command and control perspective, carrier strike groups are combat organized by mission rather than by platform.
The peacetime mission is to conduct forward presence operations, to help shape the strategic environment, deter conflict, build interoperability with allies, and respond to crises when necessary.
The SCC performs these duties from aboard the carrier due to its superior command and control capabilities.
In addition, supporting the CWC and the subordinate warfare commanders are coordinators who manage force sensors and assets within the strike group.
USS Theodore Roosevelt did not have an embarked CSG while the carrier was going through its four-year-long Refueling and Complex Overhaul (RCOH)[11] which was expected to be completed by August 2013.
Theodore Roosevelt was assigned to Carrier Strike Group Twelve subsequent to deactivation of USS Enterprise on 1 December 2012.
USS Abraham Lincoln was shifted to Newport News, Virginia, for its Refueling and Complex Overhaul, in August 2012[12] which was delayed until March 2013.
[13] On 14 January 2014, the U.S. Navy announced that USS Theodore Roosevelt would shift its home-port to Naval Base San Diego, California, becoming part of the U.S. Third Fleet.
[13] As of January 2012[update] the U.S. Navy was committed to maintaining 11 carriers, but only had 10 active until USS Gerald R. Ford went into service in 2017.
[14][15] On 4 August 2017, George Washington entered dry dock in Newport News, Virginia, for a four-year Refueling and Complex Overhaul (RCOH).
In 2014, CSFTLANT was again redesignated as Carrier Strike Group 4, retaining its role as the training and certification command for all US Fleet Forces assigned warships.
