The Space Force is adding $4.4 billion to its contracting pool for the Andromeda program, lifting the vehicle’s award ceiling from $1.8 billion to $6.2 billion.
Why the service widened the Andromeda pool
The Space Force said the fiscal 2027 Pentagon budget request was “significantly increased” shortly before the original award in April in order to meet “the escalating threat environment projected for CY 2030+.” The additional funding expands the Andromeda Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle so it can support multiple, next-generation space domain awareness efforts beyond the initial tasking.
RG-XX: a planned successor to GSSAP
The original Andromeda award set up competition among 14 companies to design a new constellation, RG-XX, intended to replace the current Geosynchronous Space Situational Awareness Program (GSSAP) neighborhood-watch satellites. The RG-XX birds are described in the budget documents as smaller, lower-cost commercial satellites with more mobility, a refueling capacity and a longer life span than the GSSAP sats. The Space Force requested $355 million in FY27 to start RG-XX development, and counted on $2.8 billion over the five-year budget cycle to field the constellation.
Budget documents schedule RG-XX launches in three “increments,” with the first set slated for early FY29 and the final set in late FY30.
SG-XX and SILENTBARKER: moving a classified capability under Andromeda
Monday’s announcement makes clear the Andromeda IDIQ will also fund a future replacement for the classified SILENTBARKER space surveillance constellation that the Space Force operates in tandem with the National Reconnaissance Office (NRO). Space Systems Command revealed in December that the service would not partner with the NRO for the replacement birds. The SG-XX replacement is expected to carry wide-field-of-view cameras to perform broad surveillance of the space environment.
The FY27 request includes $370 million to begin SG-XX development, and the service programmed $1.7 billion through FY31. The budget documents show a first SG-XX launch planned for FY30 and a plan to loft two prototype birds, designated YSG-XX, in FY28. The service has not yet issued a request for proposals for SG-XX.
Contract mechanics and industry competition
Andromeda is established as an IDIQ vehicle designed to field multiple task orders over time. The original award brought 14 companies into the competition pool to vie for future task orders tied to the RG-XX constellation; with the ceiling expanded to $6.2 billion, the vehicle can now accommodate a broader set of taskings — including the SG-XX work — and larger aggregate spending as the Pentagon’s FY27 request increased.
The expanded ceiling changes the scale of the procurement: rather than a narrower, $1.8 billion pool, the Space Force now holds a multi‑billion dollar contracting vehicle intended to support both constellations and associated prototyping, launch and sustainment work spanning FY27 through FY31 and beyond according to the budget documents.
How the Space Force, the NRO, and the 14 contractors may respond
- The Space Force: With higher FY27 funding requests and a larger IDIQ ceiling, the service has signaled it intends to accelerate development and fielding timelines — including prototype launches in FY28 and incremental deployments through FY30 — to address the “escalating threat environment projected for CY 2030+.”
- The National Reconnaissance Office (NRO): The Space Systems Command disclosure that the service will not partner with the NRO on SG-XX means the NRO’s role in SILENTBARKER replacement will change; the NRO’s next steps are not detailed in the announcement.
- The 14 contractors: Firms named to the original Andromeda award will compete for task orders tied to both RG-XX and the newly folded-in SG-XX work. The expanded ceiling increases the available contracting opportunity and could broaden the scope of proposals those companies pursue under the IDIQ.
The facts on the table are specific: a $4.4 billion injection raising the Andromeda ceiling to $6.2 billion, FY27 budget requests of $355 million for RG-XX and $370 million for SG-XX, prototype launches in FY28 and incremental deployments through FY30. The next concrete steps to watch are the issuance of a request for proposals for SG-XX and the task orders that will flow to the 14 awardees under the enlarged IDIQ — milestones that will determine how quickly the new, smaller, refuel-capable satellites move from budget line to orbit.
