According to Spaceflight Now, SpaceX is preparing for a rescheduled Falcon 9 launch from Vandenberg Space Force Base to deploy 21 Space Development Agency data satellites. The attempt follows an auto-abort 58 seconds before a previous launch window, after which the rocket was lowered for troubleshooting. Designated Tranche 1 Transport Layer A, the mission is part of the military’s Proliferated Warfighter Space Architecture constellation intended for missile tracking and secure communications. The Northrop Grumman-manufactured satellites are projected to begin operational service in 2027.
