SSC stands up MILCOMM + PNT System Delta

November 13, 2025

New System Delta will support Space Systems Command’s Military Communications & Positioning, Navigation, and Timing (MCPNT) Program Executive Office portfolio. The stand-up synchronizes acquisition efforts for critical space system capabilities with the new SYD working closely with USSF’s Combat Forces Command Mission Delta 31
to improve mission readiness.

Space Systems Command (SSC), the U.S. Space Force (USSF) field command responsible for developing and delivering resilient space capabilities, stood up its latest System Delta (SYD) through an assumption of command ceremony at Los Angeles Air Force Base. The new SYD 831 NAVWAR & Positioning, Navigation, and Timing (PNT) delivers Navigation Warfare and PNT capabilities to the USSF and joint warfighters.

USSF Lt. Gen. Phil Garrant, SSC commander, presides over the ceremony at which USSF Col. Neil Barnas assumes command of Systems Delta 831 on October 2, 2025 at Los Angeles Air Force Base.

Our nation’s PNT has long been the gold standard for reliability, integrity, and consistency, but in today’s threat environment, that is not enough,” said Garrant. “We all must continue to adapt and innovate to counter growing adversarial threats against our PNT systems. This SYD framework will prove to be one that embraces opportunities, energizes unity of effort, and gets after the threat!“

The new SYD 831 includes System Program Directors (SPDs), formerly known as Senior Materiel Leaders, corresponding to PNT and NAVWAR systems. In addition to the SPDs, there are direct report System Program Managers (SPM), formerly known as Materiel Leaders. The SYD 831 SPDs and SPMs are focused on developing and fielding the next generation of integrated Global Positioning System (GPS) satellites and user equipment to deliver robust, resilient PNT capabilities to the joint force, international partners, and civilian users around the world.

Navigation warfare – the ability to assure PNT capabilities – is fundamental to the American way of war,” said Col. Barnas. “GPS is also critical infrastructure to our nation’s economy and transportation networks. In this new era of a contested space domain, we must think differently about how we develop, deliver, and modernize our Navigation Warfare systems to ensure we stay ahead of the threat and secure our way of life.”

SYDs consolidate the design, development, and delivery of systems under a mission-focused command structure for acquisitions. The SYDs are complementary to Combat Force Command (CFC) Mission Deltas (MD), which are responsible for the sustainment of space systems, and will consolidate all aspects of mission-area readiness under SSC’s current PEO organizational construct.

This new alignment combines current SSC Acquisition Deltas into SYDs that have mission sets aligned to CFC MDs performing mission generation, intelligence support, and cyber defense.

The aligned MD and SYD organizations are structured to work together to improve mission readiness, achieve unity of command and effort, and ensure our Nation’s interests in, form, and to space. Additional SSC SYDs are slated for stand-up completing the synchronization of acquisition efforts for new capabilities.

Minimal changes in physical relocation of personnel are anticipated, and the SYD stand ups do not change the core missions of SSC or other field commands. USSF’s field command structure – SSC, CFC, and Space Training and Readiness (STARCOM) remain the same.

SYD 831 brings together the elements of capability development – program management, engineering, intelligence, logistics, finance, and contracting — under a single organization that is laser focused on delivering the gold standard of PNT capabilities,” Col. Barnas continued. “We are the world’s best at developing these Navigation Warfare systems, and this new System Delta construct postures us to develop advanced capabilities the Joint Force needs to deter and win against adversary.”
