Editing Kitty Hawk-class aircraft carrier (section)

==Improved ''Forrestal'' carriers==
The biggest differences from the ''Forrestal''s are greater length, and a different placement of [[elevator]]s; two are forward of the [[Aircraft carrier#Flight deck|island]], one is aft of the island and another on the portside stern. The movement of the No. 4 elevator from the forward to the aft end of the angle made it useful for aircraft movement, since the forward-end elevator in the ''Forrestal''s was sited in both the landing path and in the launch path of the waist catapults.

Three different [[shipyard]]s were used to construct the ships. ''Kitty Hawk'' was built at [[New York Shipbuilding]] Corporation, ''Constellation'' at [[New York Naval Shipyard]], ''America'' and ''John F. Kennedy'' at [[Newport News Shipbuilding]]. ''John F. Kennedy'' is similar to the earlier units in flight deck arrangement and propulsion, but has enough differences that she is placed in her own class. Propulsion consisted of four Westinghouse geared turbines, {{convert|280000|shp|lk=in}}, four shafts with eight {{convert|1200|psi}} [[Foster Wheeler Corporation|Foster Wheeler]] boilers.
