The U.S. Navy had proposed building destroyer flotilla leaders as early as 1917, but Congress had refused funding for the ships, and it was not until 1927 that the proposal was revived. A preliminary design was drafted by January 1932 for a fast, powerful destroyer with some splinter protection and armed with the then-new 5"/38 dual-purpose gun. The displacement was fixed at 1850 tons, the treaty limit. Authorization for construction of eight ships of the Porter class was given in 1933 and they were completed in 1936-1937.
Unfortunately, the final design mounted the main
guns in twin turrets with only a 30° maximum
elevation, making them useless against
they had superior fire control against surface targets. These
were finally replaced with high-angle turrets in 1944. Extensive
modification was required to reduce top weight enough to
permit increased to the light antiaircraft battery, though most of
work was completed before war broke out.
