USS George H. W. Bush (CVN-77) is the tenth and last Nimitz class supercarrier of the United States Navy.[1] She is named for former President George H. W. Bush, who was a naval aviator during World War II.

She is the second United States aircraft carrier to be named after a naval aviator (Forrestal was the first). Other naval vessels named for aviators include frigates McClusky and Thach, and destroyer Massey, all named for aviators who commanded formations in the Battle of Midway. George H.W. Bush is also the second aircraft carrier, following Ronald Reagan, to be named after a living former President (although former President Ronald Reagan has since died). A Nimitz class ship, George H. W. Bush differs from her predecessors even more than CVNs 68–70 did from CVNs 71–76.[citation needed]

Early history

Construction began in 2001 by the Northrop Grumman Newport News shipyard, at a cost of $6.2 billion.[2] The aircraft carrier was christened on 7 October 2006, and delivery was set for late 2008.[1] She left Northrop Grumman Ship Building for the first time on 23 December 2008 and was commissioned 10 January 2009 at Norfolk Naval Station[8] prior to her completion. The carrier completed her acceptance sea trials on 10 April 2009[9] and was delivered to the Navy on May 11.[10] The first fixed-wing flight made history May 19, 2009, after safely landing an F/A-18F Super Hornet. The Hornet was flown by Lt. Patrick McKenna and Cmdr. Beau Duarte, from Air Test and Evaluation Squadron (VX) 23 at Naval Air Station Patuxent River, Md. And, the first arrested landing, known as a "trap," was made at 2:07 p.m.EDT.[11] This launch and trap is part of the flight deck certification process going on in the Atlantic Ocean.[12]

George H. W. Bush is the final Nimitz class aircraft carrier with the Gerald R. Ford class of aircraft carriers succeeding the Nimitz class.

Features of CVN-77

Section ref: Global[13]

There are several features differentiate CVN-77 from other ships in the Nimitz class. A smaller island design has be changed significantly to improved flight deck access and reduced signature and electronic self-interference. The signature reduction of the ship was improved with a curved flight deck edges and an enclosed antenna farms. A bulbous bow provides more buoyancy to the bow and, combined with new hull coatings, makes the hull more efficient. The ship has a new propeller design.[14] The passive jet blast deflector has been redesigned and the new materials mean reduced maintenance costs. A new configuration in the aircraft pit stop process; semi-automated refueling and servicing with a new deck location provides faster, more efficient air wing pit stops and requires fewer personnel. A newly designed hangar bay has reduced clutter. A new manpower reduction plan consisting of the latest electronics and communications technology, space rearrangement, operational procedure changes, advanced sensor technologies and condition-based maintenance systems all allow for a smaller, and specially-trained crew will provide cost-savings in the ship. A new zonal electrical distribution systems will isolate the potential for problems and minimizes the effect on the rest of the ship. An automation insertion plan consisting of material movement devices, semi-autonomous, gravity compensated weapons handling devices, damage control automation systems and components will reduce the ship's crew and costs. Other improvements will implement Vacuum Collection / Marine Sanitation Device (VC/MSD): Most ships in the U.S. Navy utilize a Collection Holding and Transfer (CHT) system to handle sewage waste. Several ships add a vacuum collection capacity or VCHT. A Septic systems, when used aboard ships, are referred to as Marine Sanitation Devices, often used in U.S. Coast Guard ships. Bush is the first and only aircraft carrier in the U.S. Navy to combine the two technologies. The "VC/MSD" system onboard CVN 77 is one of a kind. The next class of U.S. Navy aircraft carriers are likely to use plasma arc waste disposal systems.
