The launch of a United Launch Atlas V 551 rocket carrying the STP-3 mission for the U.S. Space Force’s Space and Missile Systems Center (SMC) has been delayed to enable the customer to evaluate the launch readiness of the STP Satellite-6 spacecraft.

ULA’s next launch is Boeing’s CST-100 Starliner, Orbital Flight Test-2 (OFT-2), aboard an Atlas V rocket, planned for no earlier than March 25, 2021, from Space Launch Complex-41 at Cape Canaveral Space Force Station.
