SDA Posts Request for Information related to Tracking Layer for Tranche 3 of Proliferated Warfighter Space Architecture

Posted On: June 28, 2024

Response Date: July 29, 2024, noon ET

SDA released a request for information (RFI) to gather input for the Tranche 3 (T3) Tracking Layer of the Proliferated Warfighter Space Architecture (PWSA). The RFI provides an opportunity for industry to review and offer feedback in advance of solicitation posting. The T3 Tracking Layer will accelerate the proliferation of missile defense capability to provide low-latency fire control-quality data, while continuing to provide global, persistent indications, detection, warning, tracking, and identification of conventional and advanced missile threats, including hypersonic missile systems.

SDA plans to purchase and deploy approx. 54 – and potentially more – space vehicles (SV) with infrared (IR) sensors in six orbital planes using one or more vendors. SDA may also acquire additional satellites and sensor payloads under this other transaction authority (OTA) agreement to inform requirements and constellation design. The first orbital plane of the T3 Tracking Layer constellation will be launched no later than April 31, 2029, with the launches of subsequent orbital planes expected to follow on one-month intervals. 

SDA requires each SV and communications system to be interoperable with the SVs and systems developed by all other PWSA performers. Additionally, all SVs must operate in an integrated fashion through a common ground system.

Information gathered through this RFI may inform future solicitations. View the full request for information at the link for additional details and submission instructions. Industry feedback is requested by July 29, 2024 at noon ET.
