Yet the importance of the carrier fleet, and the life cycle of its nuclear super-carriers, have kept support for this program strong even as concerns over cost growth have risen. As the successor to the 102,000 ton Nimitz/Theodore Roosevelt Class super-carriers, the CVN-21 program aims to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and a new integrated warfare system that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. full sized image Advance construction on the as yet unnamed CVN 78 is beginning in 2005, allowing shipbuilders to test the design-build strategy before overall construction begins in 2007. CVN 78 will be the first true CVN-21 Class ship, though the transitional Nimitz Class CVN 77 George H. W. Bush will incorporate some elements like the improved nuclear power plant, improved internal electronics and communications, et. al. The target date for CVN 78 commissioning is 2014, whereupon it will replace America's first nuclear-powered aircraft carrier - the 50+ year old USS Enterprise (CVN 65). CVN 78 is also expected to serve for 50 years, from 2014-2064. CVN-77 - George H.W. Bush CVN 77 will enter the fleet in 2008, as the two remaining 47 year-old Kitty Hawk-class carriers are retired. By early 2002 CVN-77 did not have a name yet, though Sen. John Warner, chairman of the Senate Armed Services Committee, had suggested the vessel be called Lexington. The name is rich in naval tradition and held by two illustrious carriers, one of which sank in the Battle of Coral Sea in 1942. On December 9, 2002 Secretary of the Navy Gordon England officially named the Navy's 10th Nimitz-class aircraft carrier, CVN 77, in honor of World War II naval aviator and former President of the United States George Herbert Walker Bush during a ceremony at the Pentagon. Construction of the latest Nimitz-class aircraft carrier, CVN 77 began in 2001 with a projected delivery in 2008. CVN 77 is the first in a three-ship technology-driven transition that will introduce improvements over 18 years from CVN 77 through CVNX 2. A principal focus of this transition is on reducing crew workload by identifying and improving manpower intensive tasks and processes. As in the latest commercial ships, controls on the carrier's bridge and propulsion plant will be automated and combat systems will be integrated into a modernized computing architecture to reduce manpower and improve performance. Antennas will be built into a redesign island to reduce the ship's radar signature. � 2005 Watershed Publishing LLC. All rights reserved.
