The threat posed by the Japanese assault demolition boats proved very real. Early in the mid watch on 4 May 1945, one of the ships in Lynx's task unit, her sister ship "Carina", was hit by a suicide boat. A Flash Red at 02:04 sent ships in the vicinity back to general quarters and making smoke, evolutions ended with a Flash White at 04:52. Underway at 07:41 to rendezvous with Ulithi-bound Convoy OKU 3, "Lynx" went to general quarters upon receipt of a Flash Red ten minutes into her voyage, 07:51, remaining at battle stations through her rendezvous with the convoy one hour later. Standing down from general quarters at 09:24, the cargo ship took departure from Okinawa at 09:35. Another Flash Red, however, came through within a quarter of an hour, with "Lynx" noting shipping under attack and antiaircraft fire shooting down several planes. OKU-3 escaped unscathed and proceeded on its voyage unmolested, reaching Ulithi at mid-day on 9 May.
