# SDA Pursues PWSA Ground Interoperability

The Space Development Agency (SDA) is exploring ways to make the Proliferated Warfighter Space Architecture (PWSA) ground network more open and interoperable. In September 2026, SDA issued an industry inquiry on interoperability and is also acquiring ground stations for later PWSA stages. The activity could create opportunities for suppliers of optical ground stations and interoperable communications equipment, although the signal provides no solicitation number, contract value, or procurement contact.

- Companies with optical ground station or interoperable communications capabilities can use SDA’s industry engagement to assess how their equipment may support the PWSA ground network.
- Contractors should review SDA procurement notices for the later-stage ground station acquisitions; no specific solicitation or deadline is identified in the signal.
- The focus on open interfaces and interoperability may be relevant to suppliers positioning equipment to integrate with a broader, multi-provider ground network.
