In any event, the "Tonkin Gulf Incident" prompted American retaliation. "Constellation" joined "Ticonderoga" off North Vietnam the following day, and together they launched Operation Pierce Arrow, sixty-four sorties against the bases from which the attacks had been launched and against an oil storage depot known to have been used to support those bases. Planes from "Constellation" hit the VPN bases at Hongay and Loc Chao in the north while "Ticonderoga" aircraft went after three targets in the south: the motor torpedo boat bases at Quang Khe and Phuc Loi as well as the Vinh oil storage depot. At the last-named target, American planes set fire to 12 of the 14 oil storage tanks sending almost 10 percent of North Vietnam's oil reserves up in smoke. Of more lasting significance both to the warship and the country, however, the incident prompted the United States Congress to pass the Tonkin Gulf Resolution, the legal foundation for the United States to deploy conventional US military forces and directly confront North Vietnam in open warfare; which would ultimately involve the United States in a bloody and costly war in Indochina for the ensuing eight and a half years. Throughout that period, the "Turner Joy" would serve repeatedly throughout the conflict.
