On 24 June, during an air raid by Japanese G4M "Betties", "Phaon" suffered a near-miss on the starboard side. The damage to the ship was not very serious but the shrapnel fragments killed two of her men and injured eleven others. That day, she worked on a PCS and two LCIs, also repairing other small craft in preparation for the invasion of Tinian. On 24 July, the morning of the Tinian invasion, the destroyer came alongside, with numerous dead and wounded officers and men. She had suffered several direct hits from a Japanese shore battery and her bridge was practically torn away. While "Phaon"s medical department cared for the wounded, her repair department patched up the ship, enabling "Norman Scott" to pull away two days later.
