Design Evolution
As finally built, the Clemson class would be a fairly straightforward expansion of the Wickes-class destroyers. While the Wickes class had given good service there was a desire to build a class more tailored towards the anti-submarine role, and as such several design studies were completed mainly about designing the class with better range. These designs included a reduction in speed to between 26 and 28 knots, freeing up displacement for depth charges and more fuel.
Upgrading the gun armament from 4" to a 5" system was also considered. In addition the tapered stern of the Wickes-class destroyers resulted in a large turning radius and a correction to this defect was also sought. In the end the General Board decided the 35 knot speed be retained so as to allow the Clemson class to be used as a fleet escort. The pressing need for destroyers overruled any change that would slow production compared to the proceeding Wickes class. Wing tanks for fuel oil were installed on either side of the ships to increase the operational range. This design choice meant the fuel oil would be stored above the waterline and create additional vulnerability, but the Navy felt a 4900 nm range was worth the risk. Additional improvements included provisions for 5" guns to be installed at a later date, an enlarged rudder to help reduce the turn radius, and an additional pair of 3" anti-aircraft guns on the deck-house.

Famous quotes containing the words design and/or evolution:
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
