White House Nominates Lt. Gen. David Miller to Lead U.S. Space Command

The nomination signals a push to integrate offensive space-control capabilities as SPACECOM prepares a phased move to a new Redstone Arsenal headquarters.

Overview

  • The White House formally nominated Lt. Gen. David N. Miller Jr. on Wednesday, Sept. 30, 2026, to become commander of U.S. Space Command, a move reported and confirmed by multiple defense outlets and SPACECOM.
  • Miller is currently the Space Force’s deputy chief for strategy, plans, programs and requirements and is a career space operator who led Space Operations Command and served in senior SPACECOM operations roles.
  • His promotion and assignment require Senate confirmation and a formal hearing has not yet been scheduled, leaving the change of command dependent on Senate timing and procedures.
  • If confirmed, Miller will oversee integration of new offensive and space-control capabilities, implementation of a developing Space Warfighting Concept, and the multi-year relocation of roughly 1,800 SPACECOM personnel to a purpose-built headquarters at Redstone Arsenal.
  • The nomination would make Miller the fourth commander since SPACECOM’s 2019 reestablishment and reflects a broader Pentagon emphasis on treating space as a contested warfighting domain with tighter joint-service coordination.
