The Fletcher category destroyer used to be the results of the 1940 normal Board experiences which sought a alternative for the Sims and Benson type destroyers of the overdue Thirties, which had displayed a few deficiencies within the components of balance and velocity. a brand new layout used to be had to preserve speed with the recent providers and battleships then at the drawing forums. After rejecting an preliminary sequence of proposals according to the sooner designs, the overall Board obtained from the Bureau of development and service 3 new proposals which extra heavily met its acknowledged standards. The features of this new layout incorporated a flushdeck hull of approximately 2050 plenty displacement mounting 5 5in/38 twin goal weapons, a unmarried 1.1 in A A weapon, and quintuple 21 in torpedo tubes.
From this preliminary layout, the vintage Fletcher classification destroyer emerged. Early examples retained the rounded bridge constitution of the sooner Benson category. whereas this association used to be compatible for ships whose fundamental challenge was once torpedo assault, it quickly grew to become obvious that it was once now not suited for the expanding calls for put on the destroyer kind to supply anti-aircraft security for the proposed speedy vendors. as a result, a brand new bridge used to be designed with angular aspects and an open bridge thoroughly round the enclosed bridge constitution, straight away simplifying building and extending air safeguard capability. whilst, so one can bring up balance and supply for the inevitable raises in topside weight that may come from the call for for extra anti-aircraft guns and electronics, the root for the Mk 37 director used to be reduced approximately six ft. the outcome was once the 'square bridge' Fletcher, the 1st of which wasBrownson (DD 518). It was once to this preliminary batch of'square bridge' devices that The Sullivans belonged.
