"Ronald Reagan" and her Carrier Strike Group (CSG) departed North Island, Coronado in San Diego on 27 January 2007 on an unscheduled surge deployment to the Western Pacific, fulfilling the role of the forward deployed carrier while she underwent maintenance in Japan. On 20 April 2007, "Ronald Reagan" and her CSG returned to Coronado. The "surge deployment" was part of the Navy's Fleet Response Plan, which provides the US with the ability to respond to any global commitment with flexible and sustainable forces and the ability to rapidly respond to a range of situations on short notice.
