(USN) Four TDR-1 Assault Drones from Special Task Air Group One (STAG-1) target anti-aircraft guns atop Kangu Hill and the Pororeri River bridge north of Kangu Hill (Mission 2). The first two TDRs hit the lower slope Kangu Hill, on the northeast slope near anti-aircraft gun emplacements and the other 50' from the summit but the bomb did not detonate. One TDR crashes (perhaps hit by anti-aircraft fire). The last is unable to find the target and explodes north of Kangu Hill.
