- West of Ulithi, Japanese submarine I-48 with its deck loaded with four Kaitens was spotted on the surface by US Navy Lt Frank Yourek flying a PBM-3D Mariner. The patrol aircraft released two depth charges and one Mark 24 FIDO acoustic homing torpedo that severely damaged I-48. Two days later north of Yap, destroyer escorts USS Conklin and Corbesier made a Hedgehog attack on I-48 and the submarine was sunk with all 118 hands plus the four Kaiten pilots. ww2dbase [PBM Mariner | Mark XXIV | Caroline Islands | DS]
