US Navy deploys 2nd aircraft carrier to Gulf

The US Navy says it has deployed a second aircraft carrier to the Persian Gulf amid rising tensions with Iran over its nuclear program.

Cmdr. Amy Derrick-Frost of the Bahrain-based 5th Fleet said on Monday that the deployment of the nuclear-powered USS Enterprise along the Abraham Lincoln carrier strike group marks only the fourth time in the past decade that the Navy has had two aircraft carriers operating at the same time in the region.

The two carriers will support the American military operations in Afghanistan and anti-piracy efforts off Somalia's coast and in the Gulf of Aden.

The warships also patrol the Gulf's strategic oil routes that Iran has threatened to shut down in retaliation for economic sanctions.

The deployment of the second aircraft carrier is "routine and not specific to any threat," Derrick-Frost added. She did say how long the Navy will keep the increased military presence in region.

It was in June 2010 that the U.S. had two carriers operating in the region. Before then, the carriers were deployed in March 2003 during the U.S.-led invasion of Iraq and in February 2007 in support of wars in Iraq and Afghanistan.

The Enterprise is based in Norfolk, Va. It is the Navy's first nuclear-powered aircraft carrier that is now on its last mission.

The Enterprise was commissioned in November 1961. The carrier is scheduled to be deactivated this fall.
