トンキン湾事件
Even after the Gulf of Tonkin incident, the DESOTO patrols continued. On 11 September 1964 the Director of the Naval Security Group, Pacific (DIRNAVSECGRUPAC) informed the Director of the NSA (DIRNSA) of plans for an intercept team, SIGAD USN-467P, to be aboard . The patrol was conducted by USS "Morton" and approximately one month after the Gulf of Tonkin incident. During this patrol "Morton" fired upon five fast closing targets, but was unable to confirm the targets visually. Based on radar surveillance the patrol claimed hits on three of the targets.
