On 14 April 1969, tensions with North Korea flared again as a North Korean aircraft shot down a Lockheed EC-121 Warning Star that was on a reconnaissance patrol over the eastern Sea of Japan from its base at Atsugi, Japan. The entire 31-man crew was killed. The US responded by activating Task Force 71 (TF 71) to protect future such flights over those international waters. Initially, the Task Force was to comprise "Enterprise", , , and with a screen of cruisers and destroyers. "Enterprise" arrived on station with TF 71 in late April after completion of repairs. The ships for TF 71 came mostly from Southeast Asia duty. This deployment became one of the largest shows of force in the area since the Korean War.
