On 1 and 2 July 1966, the three torpedo boats from VPN Torpedo Squadron 135; "T-333", "T-336", and "T-339", which had attacked the USS "Maddox" on 2 August 1964, came into the Tonkin Gulf again to attack two more US destroyers, only to be promptly sunk by US jets from the aircraft carriers and . Nineteen VPM sailors were taken as prisoner of war from those sunk torpedo boats, and they made it clear that no VPN torpedo boats had been sunk in 1964. It could well have been that bad weather and freakish radar conditions for which the Gulf of Tonkin is famous, caused radar echoes to appear on "Turner Joy"s screen and prompted her captain and crew to take defensive action in consideration of the events two days earlier.
