Space Systems Command (SSC) awarded Geost LLC of Tucson, Arizona an $89,510,556 contract modification (P00040) to contract FA8819-21-C-1001 on May 13, 2026, for work on the Oculus Host program. The modification brings the cumulative face value of the contract to $195,977,490. Fiscal year 2026 research, development, test, and evaluation (RDT&E) funds of $60,823,739 were obligated at the time of award. All work will be performed in Tucson, Arizona, with a period of performance running through May 13, 2033. The contracting activity is Space Systems Command, Los Angeles Air Force Base, California.
Space Systems Command and Its Acquisition Mission
Space Systems Command is the U.S. Space Force's primary acquisition organization, responsible for developing, acquiring, launching, and sustaining military space systems. Established in 2021 as the successor to Air Force Space Command's Space and Missile Systems Center, SSC manages the procurement of satellites, ground control systems, launch vehicles, and the associated research and development programs that underpin national security space operations. Its contracting activity is based at Los Angeles Air Force Base in El Segundo, California, which has served as the hub of military satellite acquisition for more than half a century. SSC works closely with the National Reconnaissance Office, the Intelligence Community, and combatant commands that depend on space-based capabilities for communications, navigation, surveillance, and missile warning. The command oversees a portfolio spanning hundreds of programs at any given time, ranging from low-earth-orbit communications constellations to highly classified systems whose existence is publicly acknowledged only through contract announcements like this one.
The use of RDT&E funding — rather than procurement appropriations — for this modification indicates that the Oculus Host program remains in a development or advanced technology demonstration phase rather than full-rate production. RDT&E dollars are used to mature technologies, build prototypes, conduct testing, and demonstrate that a system meets military requirements before the government commits to buying it in quantity. The size of the RDT&E obligation, more than $60 million in a single modification, suggests a program of meaningful scale and technical complexity, even if the full scope of what is being developed is not publicly disclosed.
Geost LLC and the Oculus Host Program
Geost LLC is a Tucson-based defense technology company focused on space domain awareness and national security space applications. The company has positioned itself in the market for systems that monitor, characterize, and respond to activity in the space environment — a mission area that has grown significantly in priority as the U.S. military has formalized its approach to space as a contested operational domain. Geost's work falls within a category of programs that are sometimes referred to as space situational awareness or space domain awareness, though the specific technical scope of the Oculus Host program has not been publicly characterized in detail by the Department of Defense.
The Oculus Host program name does not appear extensively in publicly available contract databases beyond the contract announcements themselves. The program has characteristics consistent with a restricted or sensitive acquisition — SSC manages a number of programs with limited public disclosure, particularly those touching on intelligence functions, offensive or defensive space operations, or capabilities whose technical parameters would be sensitive if widely known. The DoD contracts announcement confirms the contractor, the location, the dollar value, and the period of performance, but does not describe the specific hardware or software being developed. This is not unusual for SSC programs in certain portfolios, where even the existence of a program may be acknowledged without its technical details being released.
The cumulative contract value of nearly $196 million, built up through forty modifications since the original award in 2021 (as indicated by the FA8819-21 contract number prefix and the P00040 modification designation), confirms that this is a long-running program with sustained government investment. A modification count that high over the span of a few years indicates active ongoing development — requirements are evolving, scope adjustments are being made, and the government is continuing to fund new phases of work. This pattern is common in space development programs where hardware and software mature iteratively and the acquisition strategy is structured to accommodate technical risk rather than locking in a fixed design at the outset. The long performance period stretching to May 2033 reinforces that SSC is planning for this program to remain in active development for years to come.
What It Means for Contractors
For small and mid-size contractors interested in national security space work, the Geost Oculus Host award illustrates several dynamics that define SSC's current procurement environment. First, SSC is actively funding development programs through 2033 and beyond, signaling sustained demand for space technology services through the end of the decade. Companies with relevant technical capabilities — particularly in space situational awareness, satellite payload development, ground system software, or RF systems — should be monitoring SAM.gov for SSC solicitations and attending the command's industry days, which are the primary venues where unclassified program requirements are communicated to potential offerors.
Second, the geographic concentration of Geost's work in Tucson points to the growing role of the Southwest corridor — Tucson, Albuquerque, and the surrounding region — as a center for national security space contractors. Companies in this region have access to a talent base with backgrounds in sensors, optics, and defense electronics that aligns with SSC's requirements. For businesses outside this region considering expansion, proximity to a major SSC program performer can create subcontracting opportunities that are harder to access from a distance.
Third, the RDT&E funding profile of this contract is important context for companies evaluating whether to pursue SSC work. Development programs funded through RDT&E are structured differently from production contracts — they require engineering staff comfortable with evolving requirements, government technical reviews, and test campaign support. Firms with production-only backgrounds may find the development environment more demanding, while engineering-focused small businesses with prototype experience are well positioned. Contractors interested in SSC development programs should review the Federal Procurement Data System for related contract histories and engage SSC's small business office at Los Angeles Air Force Base to understand set-aside opportunities within this portfolio.
