By 2023, no officer has been nominated as CJTF-SO commander. Meanwhile, plans shifted for the Space Force to create a new component field command to U.S. Space Command, the United States Space Forces – Space (S4S). It would be commanded with a three-star officer with the director of staff of the Space Force being downgraded to a two-star billet to make way for it. On 17 October 2023, U.S. Space Force Major General Douglas Schiess was nominated for promotion to lieutenant general and assignment as the first commander of S4S. As S4S commander, he would also serve as the combined joint space component commander (CJFSCC).[7]
Following the confirmation of Schiess's nomination, S4S was activated on 6 December 2023 by redesignating Space Operations Command West as S4S. CFSCC and JTF-SD were also inactivated.[8][9][10] On 31 January 2024, a ceremony presided by General B. Chance Saltzman and General Stephen Whiting was held to commemorate the activation of S4S.[11]
Generally, the missions of the two deltas can be understood as Space Delta 5 / CSOC, a multinational ("combined") body controlling activities which are going on in space, primarily satellite control; and Space Delta 15, NSDC, carrying out space warfare. Space warfare or space superiority can involve activities actually underway in space; anti-satellite missile launches (historical U.S. systems have included the Program 437 and the ASM-135 ASAT); and jamming of communications by ground-based means.
