USS Hayter ( DE - 212 ) USS " Hayter " ( DE - 212 / APD - 80 ) , a " Buckley " - class destroyer escort of the United States Navy , was named in honor of Lieutenant Commander Hubert M . Hayter ( 1901 - 1942 ) , who was killed in action , while serving aboard the cruiser during the Battle of Tassafaronga on 30 November 1942 . Lieutenant Commander Hayter was serving as damage control officer when " New Orleans " received a torpedo hit , and as Central Station , his battle post , filled with asphyxiating gas he ordered all men without masks to leave the compartment giving his own to a partially stricken seaman . After clearing the compartment of all personnel , Lt . Cmdr . Hayter was finally overcome by the fumes . For this extraordinary act of heroism he was posthumously awarded the Navy Cross . " Hayter " was launched by Charleston Navy Yard , con 11 November 1943 ; sponsored by Mrs . Maurine K . Hayter , widow of the namesake ; and commissioned at Charleston on 16 March 1944 , Lieutenant Commander H . H . Theriault in command . Service history . " Hayter " departed Charleston on 1 April 1944 for shakedown training off Bermuda , and subsequently was assigned to an escort division for Atlantic duty . Between 1 June and 30 November 1944 , she made three voyages to Europe , two from Norfolk , Virginia to Bizerte and one from Casco , Maine , to Bizerte . During the voyages " Hayter " provided anti - submarine protection and transferred the division doctor to many merchant ships in the convoy needing medical assistance . " Hayter " sailed on 2 January 1945 on a special duty in the Atlantic , with other units of Escort Division 62 . Their assignment to find and sink , which had been sending vital weather reports to Axis units from the Azores area . The ships conducted several search sweeps before " Hayter " made contact with the submarine on 16 January , and after a series of lethal depth charge attacks lasting two hours the submarine was sunk . " Hayter " patrolled the Azores for a time , then joined a convoy screen for the voyage back to Norfolk , arriving on 5 February 1945 . Departing Casco Bay on 17 March , " Hayter " and her escorts proceeded into the north Atlantic for anti - submarine sweeps in the Iceland area . The ships made a depth charge attack on 10 April , but did not score a definite kill . The group returned to NS Argentia , Newfoundland , on 14 April , and departed four days later for anti - submarine barrier patrol , cruising between escort carrier s to the south , and , to the north . Contact was made on 23 April and all ships searched without avail until the next day , when escort reported contact on her starboard bow . As " Hayter " maneuvered to attack , " Frederick C . Davis " was struck by a torpedo on her port side amidships , breaking her in two . As the stricken ship settled and sank , " Hayter " began rescue operations , and despite rough seas , sharks , and the threat of further attacks , managed to save 65 survivors and recover 12 of the dead from the sea . Three of the survivors were revived by artificial respiration given by members of " Hayter " s crew . In the meantime , the other escorts had closed in on the submarine , , and forced it to the surface . Guns quickly sank the U - boat and her captain was later made prisoner . " Hayter " arrived Argentia on 6 May and sailed two days later for Philadelphia Navy Yard via Boston . She arrived on 22 May and began her conversion to a " Charles Lawrence " - class high speed transport , her designation becoming APD - 80 on 1 June 1945 . Emerging as a high speed transport , " Hayter " departed Philadelphia on 13 August 1945 for her refresher training off Guantanamo Bay . She subsequently operated out of Norfolk and Newport in training operations until 30 October , when she departed Norfolk for Jacksonville , Florida . Decommissioning and sale . At Jacksonville , " Hayter " was placed in the Reserve Fleet at Green Cove Springs , Florida , decommissioned on 19 March 1946 and was later moved to the Texas group , where she remained until struck on 1 December 1966 . Transferred to South Korea on 23 July 1967 , the ex - " Hayter " was commissioned into the South Korean Navy in August of that year as gunboat ROKS " Jonnam " ( PG - 86 ) ( also spelled " Jon Nam " ) . Reclassified as escort transport APD - 86 in 1972 , " Jonnam " was purchased outright by South Korea on 15 November 1974 , redesignated APD - 827 in 1980 , and again to DE - 827 in 1982 . She was stricken in 1986 .
