USS Hailey (DD-556) was a Fletcher-class destroyer of the United States Navy. She was launched on 9 March 1943 and commissioned on 30 September 1943.
Parke H. Brady became her captain on the day she entered commission. The Second World War was still underway, and Hailey began her career as a destroyer in that wartime navy. Brady's command covered her opening months at sea in the conflict.
She remained in commission through the rest of the Second World War. The destroyer survived the war and was still afloat when it ended.
She continued in United States service after that war. Joseph E. Reedy took command on 27 April 1951. Two stars marked her service in the Korean War.
On 20 July 1961 the United States loaned her to Brazil. In the Brazilian navy she served as Pernambuco (D-30). Under that name she was present for the Lobster War of 1961.
Around 1982 Brazil sank her as a target. One of her five-inch guns was later placed on view at the naval base in Rio de Janeiro.
