The United Launch Alliance (ULA) Atlas V rocket launch carrying the AEHF-6 mission for the U.S. Space Force’s Space and Missile Systems Center is delayed due to an off-nominal valve reading during launch vehicle processing.

Additional time is needed for the team to replace and retest the valve. Launch is now scheduled for no earlier than March 21.
