Development
The lessons learned from operations with the large converted battlecruiser Lexington class in comparison with the smaller purpose-built Ranger had taught the Navy that large carriers were more flexible in operational terms and were more survivable than smaller ones. As the result of this experience, the U.S. Navy built Yorktown (CV-5) and Enterprise (CV-6), commissioned in 1937 and 1938 respectively. These were fast and versatile carriers able to carry and operate over 80 warplanes which was almost as many as the much larger Lexington class.
With the addition of the 14,700 ton USS Wasp (CV-7), a scaled down version of the class, the U.S. Navy used up its full 135,000 ton Washington Naval Treaty limit of aircraft carrier tonnage. The abandonment of the arms limitation treaties system in 1937 allowed the US to begin building more carriers, and the first of this new carrier program was Hornet (CV-8), another of the class, commissioned in 1941. Improvements to the Yorktown design and freedom from the Washington Treaty limitations brought about the Essex-class carriers.
Like the earlier ships of the Lexington-class, the Yorktowns carried a seldom used catapult on the hangar deck level. This catapult was subsequently eliminated from U.S. carriers as it was relatively useless in operation. The hangar deck catapult was removed from Enterprise and Hornet in late June 1942.
All three ships of the Yorktown class were built at the Newport News Shipbuilding Company, Newport News, Virginia.

Famous quotes containing the word development:
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
—Lawrence Kutner (20th century)
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
“As long as fathers rule but do not nurture, as long as mothers nurture but do not rule, the conditions favoring the development of father-daughter incest will prevail.”
—Judith Lewis Herman (b. 1942)
