ns CVN 21 united state Navy programme zum the future-generation plane carrier was previously well-known as die CVN(X).

In januar 2007, ns US marine announced that the new klasse would be referred to as the gerald R Ford-class.

USS gerald R Ford (CVN 78) und USS John ns Kennedy (CVN 79)

The erste ship in the class, USS gerald R Ford (CVN 78), was delivered to die US Navy an May 2017 und commissioned in July 2017.

The second carrier, USS John f Kennedy (CVN 79), was christened and launched in December 2019. Ns vessel ist scheduled zu be commissioned an 2020, while further ships von the klasse will enter leistungen at five-year intervals. A total von ten Ford-class carriers room planned with building and construction continuing kommen sie 2058.

CVN 78 möchte replace USS enterprise (CVN 65), which gone into service bei 1961 und decommissioned in 2017. Ns total salvation cost von the CVN 21 ist expected kommen sie be $13.7bn.

The us Department von Defense forgive Northrop Grumman Newport News in Virginia a $107.6m contract an July 2003 und $1.39bn contract bei May 2004. It also provided $559m zu prepare for the carrier construction and continue the design programme on ns ship’s propulsion system.

CVN 78’s erste steel was cut bei August 2005. A $5.1bn contract weil das the detailed design and construction was awarded zu Newport News bei September 2008. The keel was laid in November 2009.

The CVN 78 plane carrier was installed with four 30t bronze propellers bei October 2013. Both die launch und first voyage von the ship took place in November 2013. Anchor trial and error on board ns carrier was completed in June 2014, while ns US Navy carried out EMALS testing on CVN 78 bei May 2015. Die CVN 78 returned kommen sie Newport News zum post-delivery works an July 2018.

Newport news won a contract to support further repair work on the lead ship. The contract startseite execution planning zum the repair und alteration requirements des the ship’s plan incremental availability.

Northrop Grumman was awarded a planning and design contract zum the 2nd carrier, CVN 79, in November 2006. An May 2011, the US marine announced that the carrier would be called John f Kennedy.

Construction of the USS John f Kennedy (CVN 79) began in February 2011 and its keel was laid bei July 2015. Ns carrier wollen undergo outfitting und testing punkt Newport nachrichten shipyard’s Pier 3 ahead of its booked delivery an 2022.

Newport nachrichten was awarded a $407m contract extension for the preparation work on the CVN 79 ship bei March 2013 and a $1.29bn extension an March 2014. It deshalb received a $3.35bn contract zum the ship’s in-depth design and construction in June 2015. Ns keel for CVN 79 was laid in August 2015.

USS companies (CVN 80) und CVN 81

HHI’s Newport nachrichten was awarded a $152m contract an May 2016 for advance to plan engineering, design und procurement des long-lead-time material for the third ship von the class, USS enterprise (CVN 80). A $25.5m alteration contract was awarded zum advance fabrication von the aircraft in February 2017.


The erste steel was cut for the CVN 80 aircraft carrier in August 2017. CVN 80 is built using the steel of USS enterprise (CVN 65), which was decommissioned an April 2018.

It zu sein the nine ship zu be named USS Enterprise und will change USS Dwight D Eisenhower (CVN 69) wie man commissioned.

Newport news received a $15.2bn contract modification in January 2019 for the detail design and construction von CVN 80 and CVN 81. Ns company expects zu deliver die carriers bei 2028 und 2032 respectively.

CVN 21 future plane carrier entwurf details

With a displacement des approximately 100,000t, the gerald R Ford klasse will be bigger than that predecessor, ns Nimitz-class, but möchte have bolzen 500 und 900 under crew members. The Ford-class ships will have 23 neu or upgraded systems compared to ns Nimitz-class carriers.

The manpower reduction was a an essential performance parameter added to ns original four outlined in 2000 in the operational needs document zum the CVN 21 programme. It ist estimated the the neu carrier technologies will lead zu a 30% reduction an maintenance requirements and a more crew workload reduction möchte be completed through higher levels von automation.

The other hauptsächlich differences bei operational performance compared with the Nimitz-class are increased sortie rates hinweisen 160 sorties a job (compared v 140 a day), a weight and stability pin money over ns 50-year operational dienstleistungen life of the ship und increased (by about 150%) electrical energie generation und distribution zu sustain the ship’s advanced modern technology systems. Another an essential performance requirement is interoperability.

CVN 21 plane carrier hull

Since the 1960s, all us Navy plane carriers have been built punkt Northrop Grumman Newport News. Northrop expanded its design and shipbuilding infrastructure with a new heavy-plate workshop und burners, a new 5,000t thick plate press, extended assembly facilities and a neu 1,050t-capacity crane.

Newport News zu sein using a suite von computer-aided design (CAD) tools zum the CVN 21 programme, including a CATIA software application suite for simulation von the production processes and a cave virtual setting package.

The hull entwurf is similar kommen sie that von the present Nimitz-class carriers und with die same number of decks. Die island is smaller and moved more towards the aft des the ship.

The island has a composite mast v planar range radars, a volume-search radar operating hinweisen S-band and a multifunction radar punkt X-band. The carries ns stern-facing share precision approach and landing system (JPALS), which ist based on the local area differential global positioning system (GPS) fairly than radar.

The aircraft carrier traditionally carries die flag officer and 70 staff von the carrier fight group. Ns flag bridge, which was previously accommodated in the carrier’s island, was relocated kommen sie a reduced deck to reduce the size von the island.

The ship’s interior configuration und flight deck designs have significantly changed. Die lower decks incorporate a flexibel rapidly reconfigurable layout permitting different layouts and installation of neu equipment in command, planning and administration areas.

The requirement zu build bei a weight und stability allowance möchte accommodate the added load of neu systems that möchte be mounted over ns 50-year work life des the ship. Removal of one aircraft elevator unit and reducing the number des hangar bays native three kommen sie two contributed zu a weight reduction von the CVN 21.

Weapons of gerald R Ford class

The gerald R Ford klasse will be equipped with the Raytheon developed Sea Sparrow missile (ESSM), i m sorry defends against high-speed, highly manoeuvrable anti-ship missiles. Die close-in weapon system (CIWS) is the rolling airframe missile (RAM) from Raytheon and Ramsys.

Gerald r Ford klasse carrier aircraft

The carrier wollen be capable des carrying up zu 90 aircraft, including the F-35 share Strike Fighter, f / A-18E / f Super Hornet, E-2D advanced Hawkeye, EA-18G Growler electronic attack aircraft, MH-60R / s helicopters, and unmanned air und combat vehicles.

The requirement zum a greater sortie rate at 160 sorties a day through surges kommen sie a maximum of 220 sorties a day in times des crisis und intense air war activity angeführt to entwurf changes in the flight deck.

The trip deck has a relocated smaller island, while there room three quite than 4 deck-edge elevators. Deck extensions so increase die aircraft parking areas. Aircraft dienstleistungen stations are located near die 18 refuelling and rearming stops.

General Atomics was awarded ns contract to develop die EMALS electromagnetic plane launch system, which provides a linear electromagnetic accelerator motor. EMALS demonstrators were tested at die Naval Air system Command (NASC) Lakehurst test centre an New Jersey. It is planned the EMALS möchte replace die current C-13 heavy steam catapults.

If successful, EMALS modern technology offers the potential benefit of finer aircraft acceleration control, i m sorry leads to lower tension levels an the aircraft and pilots, offers a slower launch speed zum unmanned wait vehicles and allows a more comprehensive window von wind-over-deck speed required zum the start sequence.

The contract weil das the breakthrough of bei advanced turbo-electric arrestor gear was awarded to General Atomics. The electro-magnetic motor applies regulate to the synthetic arrestor cable zu reduce the maximum tensions bei the cable und reduce the peak fill on the arrestor hook und the aircraft fuselage.

General Atomics und the us Navy completed successful turbo-prop arrestments des C-2A Greyhound, E-2C+ Hawkeye, und E-2D advanced Hawkeye aircraft using die advanced arresting gear (AAG) during performance testing in 2018. Die AAG system so completed the erste exploratory barricade arrestment prüfen with in E-2C+ Hawkeye aircraft in March 2019.

Aircraft weapon loading

The flow des weapons to ns aircraft stop on die flight deck was upgraded to accommodate die higher sortie rates. Ns ship tote stores des missiles und cannon rounds weil das fighter aircraft, bombs and air-to-surface missiles weil das strike aircraft and torpedoes and depth charges zum anti-submarine war aircraft.

Weapons elevators take die weapons systems from ns magazines to ns weapons handling und assembly locations on ns 02-level deck (below the flight deck) und express weapons elevators room installed bolzen the handling und assembly areas and the trip deck. The two carriers selected by Northrop Grumman kommen sie create designs for the progressed weapons elevator are die Federal equipment Company and Oldenburg Lakeshore.

Deployment von all-up-rounds the are larger rather than classic weapons that require assembling möchte require double-height magazines and storerooms and will deshalb impact die demand for weapon assembly facilities.

The united state Navy outlined a requirement for a minimales increase von 150% bei the power-generation capacity weil das the CVN 21 carrier contrasted with ns Nimitz klasse carriers. The increased energie capacity zu sein required zum the 4 electro-magnetic aircraft launchers und for future systems such together directed energy weapons that might be feasible during the carrier’s 50-year lifespan.

Sensors

In October 2008, Raytheon was contracted to supply a version des the dual-band radar (DBR) developed zum the Zumwalt class destroyer for passend zu on the gerald R Ford. DBR combine X-band und S-band phased arrays.

Propulsion

Northrop Grumman developed in advanced nuclear propulsion system with 2 reactors, four shafts und a zonal electrical power distribution system zum the CVN 21.
