After '' Card '' was sunk , North Vietnam made use of the incident for propaganda purposes . On October 20 , 1964 , the North Vietnamese government issued a postage stamp which proclaimed an " Aircraft Carrier of America sunk in the Harbor of Saigon " , to praise the Viet Cong commandos who carried out the attack . The US Navy refused to admit '' Card '' had been sunk even for a brief period of time , instead stating '' Card '' was damaged and quickly repaired . For the remainder of 1964 , the VC launched further attacks on US targets such as the Brinks Hotel and Bien Hoa Air Base , but there were no significant responses from the US military . '' Card '' returned to service December 11 , 1964 and remained in service until 1970 , when she was placed in the Reserve Fleet
