Schiess will succeed Gen. Chance Saltzman, who has served as chief of space operations since November 2022 and is expected to retire later this month. Upon assuming the position, Schiess will be promoted to four-star general, becoming the Space Force’s senior uniformed officer and serving as a member of the Joint Chiefs of Staff.

President Donald Trump nominated Schiess in May following Saltzman’s planned retirement.

Schiess currently serves as deputy chief of space operations, a role in which he oversees the Space Force’s global operations, readiness, sustainment and training. Before joining the Space Force headquarters staff, he commanded U.S. Space Forces–Space, overseeing military space operations and integrating space capabilities in support of combatant commanders worldwide.

Earlier in his career, Schiess served as an Air Force missile officer and held assignments in military launch, GPS and satellite communications before commanding the 21st Space Wing and the 45th Space Wing. His 34-year military career also includes operational, staff and joint assignments supporting U.S. Central Command, U.S. Space Command and multinational operations.

During his confirmation hearing before the Senate Armed Services Committee in July, Schiess told lawmakers the Space Force must continue organizing, training and equipping Guardians to defend U.S. space capabilities, protect the joint force from space-enabled attack and deliver the capabilities needed to support military operations across the full range of missions.

“Our purpose is not confrontation, but deterrence, ensuring no adversary believes aggression against the United States will succeed,” Schiess told the committee.

He said he would work to ensure Guardians remain ready, the service’s capabilities remain resilient and its partnerships remain strong.

In written responses to the Senate Armed Services Committee, Schiess said he would prioritize strengthening the connection between force design, acquisition programs and combatant commanders’ operational requirements.

He also said he would focus on expanding launch infrastructure, improving the Space Force’s testing enterprise and continuing efforts to strengthen the acquisition workforce needed to field new capabilities more rapidly.
