The USS Haynsworth (DD-700), was an Allen M. Sumner-class destroyer of the United States Navy. The ship was launched on 15 April 1944 by the Federal Shipbuilding & Drydock Co., Kearny, New Jersey; sponsored by Mrs. Haynsworth, widow of Commander Haynsworth; and commissioned on 22 June 1944, with Commander Robert Brodie, Jr., in command. The USS Haynsworth (DD-700) departed New York on 20 September 1944 escorting Queen Mary with Prime Minister Winston Churchill on board. Rendezvousing with British escorts, the ship returned to New York and sailed on 26 September via the Panama Canal Zone and San Pedro, arriving at Pearl Harbor on 20 October. During the next three months, it operated with the 3rd and 5th Fleets as part of the screen for the Fast Carrier Task Force. Asbestos is a highly toxic material that has a high resistance to heat. It was a very popular material that was used widely in the shipbuilding industry in the United States for decades. It wasn’t until the material was discovered to be very dangerous in the 1970s when its use was stopped. Exposure to asbestos can result in many health conditions, which can include lung cancer, asbestosis, and mesothelioma.
