Improved Forrestal carriers

The biggest differences from the Forrestals are greater length, and a different placement of elevator

s; two are forward of the island, one is aft of the island and another on the portside stern. The movement of the #4 elevator from the forward to the after end of the angle made it useful for aircraft movement, since the forward-end elevator was useless as it was in both the landing path and in the launch path of the #3 and #4 catapults.

Construction and design differences

The first three units were constructed with a Terrier
RIM-2 Terrier
The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile , and was among the earliest surface-to-air missiles to equip United States Navy ships. Originally, the Terrier had a launch thrust of 23 kN , and weight of 1392 kg...

AN/SPG-55
The AN/SPG-55 was a tracking / illumination radar for Terrier and RIM-67 Standard missiles . It was used for target tracking and Surface-to-air missile guidance on numerous ships including s,s, s and Farragut class destroyers. It was also used on the nuclear powered single units , and...

 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

America had several differences from the lead units of the class. Instead of two forward anchor
Anchor
An anchor is a device, normally made of metal, that is used to connect a vessel to the bed of a body of water to prevent the vessel from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα .Anchors can either be temporary or permanent...

. America was the only post-World War II U.S. carrier to be built with sonar, though it was removed in the early 1980s. She also had a narrow smokestack compared to prior units.

John F. Kennedy class

was originally scheduled to be the fourth Kitty Hawk-class carrier, but because she received so many modifications during construction, she formed her own ship class and is often listed as a single-class carrier. Kennedy had similar design changes regarding the anchors to accommodate a sonar array, but the sonar was never installed. There were also plans to make her nuclear powered, but since Congress would not authorize it, Kennedy was constructed as a conventionally powered carrier. Her smokestack is also different and tilts outboard to send stack gas away from the flight deck. The angled end of the waist is also different than the other Kitty Hawks, bearing a closer resemblance to that of the Nimitz-class

. Kennedy is also 17 feet (5.2 m) shorter in length than the other Kitty Hawk-class carriers.

Decommission

From 1987 to 1991 Kitty Hawk was overhauled for $785 million under the Service Life Extension Program (SLEP) at Philadelphia Naval Shipyard

The Philadelphia Naval Business Center, formerly known as the Philadelphia Naval Shipyard and Philadelphia Navy Yard, was the first naval shipyard of the United States. The U.S. Navy reduced its activities there in the 1990s, and ended most of them on September 30, 1995...

. From 1990 to 1992, Constellation received her $800 million service life extension also in Philadelphia. The program was intended to add 15 years to the life of the ships. John F. Kennedy was not overhauled as part of SLEP. Instead, from 1993 to 1995, she received a $491 million overhaul. It was the final project of Philadelphia Naval Shipyard prior to its closing. America had been scheduled to be overhauled under the service life extension program after Constellation, but she was decommissioned 9 August 1996 instead, during a time of budget cuts after the Cold War

Constellation was decommissioned 7 August 2003. John F. Kennedy was decommissioned on 23 March 2007. Only Kitty Hawk remained in service as of early 2008 and was replaced by as the forward-deployed carrier in Japan. Kitty Hawk returned to the United States after the turnover. She was decommissioned on 31 January 2009.
