The launch supports the USSF-259 mission.
Following stage separation, the rocket's first-stage booster landed on the Of Course I Still Love You droneship stationed in the Pacific Ocean. It was the 13th flight for the booster, which previously launched Sentinel-6B, Twilight, NROL-172, Transporter-17, and eight Starlink missions.
The launch was originally scheduled for Tuesday night, but SpaceX says its team decided to stand down to troubleshoot an issue.
