A new acquisition office gets its leader
The U.S. Space Force has formally announced Gurpartap “GP” Sandhoo as the head of its new Missile Warning and Tracking Portfolio Acquisition Executive office, while he continues serving as director of the Space Development Agency. The move formalizes a structural change that had been under way inside the service and places one official at the center of several of its most important missile-warning procurement efforts.
According to the supplied reporting, Sandhoo took on the dual role on May 11. The announcement also elevated him from acting director of the Space Development Agency to permanent director. That matters because it consolidates authority over an expanding and increasingly interconnected set of space-based missile warning and tracking programs.
The Space Force framed the change as part of a broader effort to align authority with accountability. In practical terms, the service is reorganizing around mission portfolios rather than managing major satellite systems as more isolated programs.
What the new office will oversee
The Missile Warning and Tracking Portfolio Acquisition Executive office was announced on March 17. It is set to encompass several major efforts. These include the Space Development Agency’s Tracking Layer in low Earth orbit, the Next-Generation Overhead Persistent Infrared constellation, and the Resilient Missile Warning and Tracking Medium Earth Orbit program.
Each of those efforts serves a related but distinct role in the architecture for detecting and tracking missile threats. The candidate material describes Next-Gen OPIR as the successor to the six operational Space-Based Infrared System satellites, with two satellites planned for geosynchronous orbit and two for polar orbit. The medium Earth orbit program is described as being optimized for tracking hypersonic missiles.
Bringing those activities under a single portfolio structure is significant because missile warning and tracking are no longer being treated as a narrow, single-constellation problem. The architecture is being spread across multiple orbital regimes and acquisition pathways. That makes integration, budgeting, and oversight more complex, and it helps explain why the service is concentrating responsibility.
Sandhoo’s dual role reflects a broader transition
Sandhoo has led the Space Development Agency as acting director since September 2025, according to the supplied SpaceNews text. Under the new arrangement, he continues overseeing SDA’s Tranches 1 and 2 of the Proliferated Warfighter Space Architecture while also taking responsibility for future missile-warning tranches as they move into the Space Force’s new structure.
This is not simply a title change. It indicates that the Space Force is using the new office to manage a transition from SDA-led development into a more mature acquisition framework tied directly to mission portfolios. That transition is important because SDA has often been associated with faster, tranche-based development cycles and a different organizational culture than traditional defense acquisition offices.
The reporting also notes that the Transport Layer portion of the Proliferated Warfighter Space Architecture will not continue into Tranche 3. Instead, that mission is being folded into a larger initiative called the Space Data Network under another portfolio executive. That separation further clarifies the Space Force’s attempt to organize programs by mission function instead of by legacy organizational boundaries.
Why missile warning and tracking now occupy center stage
The creation of a dedicated portfolio executive for missile warning and tracking reflects the strategic weight of the mission. Global missile warning has long been foundational, but the addition of new tracking demands, especially for hypersonic threats, is forcing changes in both architecture and management.
Low Earth orbit tracking layers, medium Earth orbit systems, and next-generation infrared satellites are all being developed in a context where resilience, persistence, and responsiveness matter more than relying on a small number of exquisite platforms. The new structure appears intended to reduce fragmentation as those systems proliferate.
The Space Force’s own explanation underscores that point. Thomas Ainsworth, performing the duties of Air Force assistant secretary for space acquisition and integration, said the reorganization reflects a “strategic commitment” to accomplish the global missile warning and tracking mission. That language suggests the service sees organizational design as an operational issue, not just a bureaucratic one.
The future of SDA remains a live question
The leadership reshuffle also comes with uncertainty about the long-term status of the Space Development Agency as a standalone organization. The supplied SpaceNews report says the future of SDA remains under review and cites previous remarks indicating it may eventually be folded into the missile warning and tracking portfolio executive structure.
If that happens, it would mark another step in the integration of SDA’s development model into the Space Force’s mainstream acquisition system. The current arrangement already points in that direction. Sandhoo is simultaneously managing the agency and the portfolio office, which gives the service continuity during a period of institutional change.
Michael Eppolito’s move into the SDA deputy director role adds another layer of continuity. The agency is preserving leadership depth even as its responsibilities and reporting relationships evolve.
A restructuring with operational consequences
The significance of the announcement lies less in the personnel move alone than in what it says about Space Force priorities. Missile warning and tracking are being organized as an integrated mission portfolio spanning multiple constellations and orbital layers. The service is trying to tighten lines of responsibility before these systems become even larger and more central.
That choice reflects a recurring lesson in modern defense acquisition: architecture and management cannot be separated for long. Once programs become distributed across different orbits, vendors, and timelines, fragmented oversight can become a mission risk.
By placing Sandhoo over both SDA and the new portfolio office, the Space Force is attempting to keep that risk under control during a transition period. Whether the structure ultimately delivers faster fielding or better integration remains to be seen, but the direction is now clear. Missile warning and tracking are being treated as a unified strategic portfolio, and the service is reshaping its acquisition system to match.
