Editing Kitty Hawk-class aircraft carrier (section)

==Construction and design differences==
The initial design for the class was known as [[Ship Characteristics Board|SCB 127]], and ''Kitty Hawk'' and ''Constellation'' were completed to design SCB 127A.<ref name=Friedman>{{cite book |title=U.S. Aircraft Carriers: An Illustrated Design History |first=Norman |last=Friedman |pages=274–280, 317 |location=Annapolis, Maryland |publisher=United States Naval Institute |date=1983 |isbn=0-87021-739-9}}</ref>

The first three units were constructed with a [[RIM-2 Terrier|Terrier]] [[surface-to-air missile]] system. The supporting missile launchers and [[AN/SPG-55]] radars consumed a large amount of space, while at the same time duplicating the capabilities of the air defence escorts, and were later removed. ''John F. Kennedy'' did not have Terrier and was built with the shorter ranged [[Sea Sparrow]], Basic Point Defense Missile System (BPDMS). All were eventually equipped with NATO Sea Sparrow (NSSM) and [[Phalanx CIWS]] for self-defense.<ref name=MNC>{{cite book |title=Modern Naval Combat |first1=David |last1=Miller |first2=Chris |last2=Miller |pages=116–17 |location=London, New York |publisher=Salamander Books |date=1986 |isbn=0-86101-231-3}}</ref> In 2001, ''Kitty Hawk'' received two [[RIM-116 Rolling Airframe Missile|Rolling Airframe Missile]] launchers replacing the forward Sea Sparrow and Phalanx CIWS equipment.<ref>{{cite web|first=Doug |last=Huddy |url=http://www.stripes.com/01/jul01/ed072501f.html |title=USS ''Kitty Hawk'' gets upgrade with Rolling Airframe Missile weapon system |work=Stars and Stripes |date=25 July 2001 |url-status=dead |archive-url=https://web.archive.org/web/20081211005248/http://www.stripes.com/01/jul01/ed072501f.html |archive-date=11 December 2008 }}</ref> The [[SLQ-32 Electronic Warfare Suite]] was added as part of the Service Life Extension Program (SLEP) on ''Kitty Hawk'' and ''Constellation''.<ref>{{cite web |url=http://www.fas.org/man/dod-101/sys/ship/weaps/an-slq-32.htm |title=AN/SLQ-32 Electronic Warfare (EW) system |website=fas.org |date=30 June 1999 |access-date=4 May 2016}}</ref>

''America'' was designed under project SCB 127B and so had several differences from the lead units of the class.<ref name=Friedman/> Instead of two forward [[anchor]]s, one on each side, ''America'' had no port side anchor and an additional anchor astern, a change made to accommodate the AN/SQS-23 [[sonar]]. ''America'' was the only post-World War II U.S. carrier to be built with sonar, which was however removed in the early 1980s. She also had a narrow smokestack compared to prior units.<ref name=MNC/>

===''John F. Kennedy'' class===
{{USS|John F. Kennedy|CV-67|2}} was originally scheduled to be the fourth ''Kitty Hawk''-class carrier,<ref name="donation">{{cite press release |url=http://www.navy.mil/search/display.asp?story_id=49825 |title=Navy Announces Availability of ex-John F. Kennedy for Donation |publisher=US Navy |number=NNS091123-04 |author=Naval Sea Systems Command Office of Corporate Communications |date=23 November 2009 |access-date=4 May 2016 |archive-date=29 June 2011 |archive-url=https://web.archive.org/web/20110629190149/http://www.navy.mil/search/display.asp?story_id=49825 |url-status=dead }}</ref> but because she received so many modifications under project SCB 127C,<ref name=Friedman/> she formed her own ship class<ref name="donation"/> and is often listed as a single-vessel class. ''Kennedy'' had similar design changes regarding the anchors to accommodate a sonar array, but the sonar was never installed. There was also a proposal to make her nuclear powered under competing project SCB 211A,<ref name=Friedman/> but since Congress would not authorize it, ''Kennedy'' was constructed as a conventionally powered carrier.<ref name=MNC/> Her smokestack is also different and tilts outboard to send stack gas away from the flight deck. The angled end of the [[Angled flight deck|waist]] is also different from the other ''Kitty Hawk''s, bearing a closer resemblance to that of the {{sclass|Nimitz|aircraft carrier|4}}. ''Kennedy'' is also {{convert|17|ft|m}} shorter in length than the other ''Kitty Hawk''-class carriers.
