Information About Us

Features

The aircraft carrier continues to be the centerpiece of the forces necessary for forward presence. Whenever there has been a crisis, the first question has been: "Where are the carriers?" Carriers support and operate aircraft that engage in attacks on airborne, afloat, and ashore targets that threaten free use of the sea; and engage in sustained operations in support of other forces.

Aircraft carriers are deployed worldwide in support of U.S. interests and commitments. They can respond to global crises in ways ranging from peacetime presence to full-scale war. Together with their on-board air wings, the carriers have vital roles across the full spectrum of conflict.

The Nimitz-class carriers, nine operational and one under construction, are the largest warships in the world. USS Nimitz (CVN 68) was the first to undergo its initial refueling during a 33-month Refueling Complex Overhaul at Newport News Shipbuilding in Newport News, Va., in 1998. The next generation of carrier, the GERALD R. FORD Class (the lead ship hull number will be CVN 78), is programmed to start construction in 2007 and is slated to be delivered in 2015 to replace USS Enterprise (CVN 65). CVN 79 is programmed to begin construction in 2012 and to be placed in commission in 2018. 

Background

The Carrier Mission is:

  • To provide a credible, sustainable, independent forward presence and conventional deterrence in peacetime
  • To operate as the cornerstone of joint/allied maritime expeditionary forces in times of crisis
  • To operate and support aircraft attacks on enemies, protect friendly forces and engage in sustained independent operations in war

Capability

  • Powered by two nuclear reactors that can operate for more than 20 years without refueling
  • Expected to operate as Navy warship for about 50 years
  • Typical Nimitz-class ship carries 80-plus combat aircraft
  • Three two-inch diameter arresting wires on the deck bring an airplane going 150 miles per hour to a stop in less than 400 feet
