The 1,092-foot, $4.5 billion aircraft carrier USS Ronald Reagan arrived at Pearl Harbor this morning for a port visit following a seven-month deployment.

The Reagan carrier strike group includes the guided-missile cruiser Chancellorsville and the guided-missile destroyers Preble and Higgins, the Navy said.

After leaving its home port of San Diego on Feb. 2, the ships of the Reagan strike group provided aid in Japan following a magnitude 9.0 earthquake and tsunami that struck March 11.

The Navy’s 7th Fleet repositioned its ships and aircraft away from the stricken Fukushima Daiichi nuclear power plant March 13.

The Reagan and 21 other U.S. Navy ships, 132 aircraft and more than 15,000 U.S. personnel helped with relief operations, delivering more than 260 tons of supplies to people ashore, the Navy said.

The Reagan and its strike group ended relief efforts in early April and took part in Malabar 2011, an exercise involving the U.S. and Indian navies. The exercise wrapped up April 9 and involved the Pearl Harbor frigate USS Reuben James, which was not part of the carrier strike group.

The strike group later operated in the Middle East with missions in Iraq and Afghanistan.
