Вот из свежего Джейна про CVNX:
Notes: Construction of CVN 21, the first of a new generation (formerly CVN(X)) of aircraft carrier is to begin at Newport News Shipbuilding in 2007 for delivery in 2014. The displacement is expected to be of the order of 100,000 tons and the design is to incorporate an expanded flight deck, an integrated combat system, a new nuclear propulsion plant, a new electrical power and distribution system, an Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG). AAG is also to be retrofitted to the `Nimitz' class. EMALS is planned to reduce aircraft wear, increase combat capability and reduce flight deck maintenance and crew requirements. CVN 21 will require 800 fewer crewmen than the `Nimitz' class. The new propulsion plant will triple electrical power giving scope for significant advanced in war-fighting capability and future `transformation' enhancements. A new carrier of the CVN 21 class is to be delivered every five years and construction of CVN 22 will start in 2012.

TEXT :
Programmes: Nimitz was authorised in FY67, Dwight D Eisenhower in FY70, Carl Vinson in FY74, Theodore Roosevelt in FY80 and Abraham Lincoln and George Washington in FY83. Construction contracts for John C Stennis and Harry S Truman were awarded in June 1988 and for Ronald Reagan in December 1994. Authorised in FY99, construction contract for George H W Bush awarded in February 2001.
Modernisation: ACDS Block 1 Level 2 in CVN 69. SSDS Mk 2 Mod 0 installed in CVN 68 (to be upgraded to Mk 2 Mod 1 in 2004). This includes fitting RAM, ESSM and SPQ-9B radar vice Mk 23 TAS. SSDS Mk 2 Mod 1 to be fitted to CVN 69 and CVN 76 in 2003. RAM replaces one Mk 29 and all Phalanx launchers. CVN 68 completed a three-year overhaul in 2001 that included refuelling and a reshaped island. A similar refit of CVN 69 is being undertaken 2001-04 and of CVN 70 2004-07. SLY-2 intercept equipment replacing part of the SLQ-32 system from 1999.
Structure: Damage control measures include sides with system of full and empty compartments (full compartments can contain aviation fuel), approximately 2.5 in Kevlar plating over certain areas of side shell, box protection over magazine and machinery spaces. Aviation facilities include four lifts, two at the forward end of the flight deck, one to starboard abaft the island and one to port at the stern. There are four steam catapults (C13-1) and four (or three) Mk 7 Mod 3 arrester wires. Launch rate is one every 20 seconds. The hangar can hold less than half the full aircraft complement, deckhead is 25.6 ft. Aviation fuel, 9,000 tons.
Tactical Flag Command Centre for Flagship role. Mk 32 triple torpedo tubes were fitted for anti-wake homing torpedo trials, but the programme was cancelled and the tubes removed.
Operational: Multimission role of 'attack/ASW'. From CVN 70 onwards ships have an A/S control centre and A/S facilities; CVN 68 and 69 are backfitted. Endurance of 16 days for aviation fuel (steady flying). 15 years' theoretical life for nuclear reactors; greater than 1 million miles between refuelling. Ships' complements and air wings can be changed depending on the operational task.
