INTRODUCTION:

THIS IS A SOURCES SOUGHT ANNOUNCEMENT to identify potential sources that can provide PEREGRINE Sentry capabilities. PEREGRINE Sentry will support the SDA resilient missile warning and tracking (RMWT) low Earth orbit (LEO) operational mission within the PWSA Ground Program. The government intends to evolve the current PWSA ground segment into a loosely-coupled Modular Open Systems Architecture (MOSA)-compliant ground segment framework (GSF) and a secure, multi-tenant common development environment (CDE). The potential contractor will serve as the lead platform integrator responsible for ingesting new and existing third-party application developer (3PAD) capabilities, working with ground segment contractors, and managing the software ecosystem framework lifecycle on the GSF. The contractor will work in collaboration with mission partners and under the governance of the government’s enterprise system’s engineering and integration team, establishing the technical baseline using model-based systems engineering (MBSE) as the authoritative source of truth (ASOT), and executing a low-risk legacy capability transition under a strict “do no harm” paradigm.
SDA seeks sources with demonstrated technical capabilities in the core areas outlined below, with a specific preference for respondents with demonstrated, production-proven experience architecting and operationalizing systems for distributed space or ground environments that can serve as the foundation for the PEREGRINE Sentry ecosystem: •

Hybrid Cloud Infrastructure & Edge Compute: Designing, provisioning, and managing resilient platforms spanning native Commercial Cloud Enterprise (C2E) resources and on-premises physical footprints. This includes physical hardware provisioning, network transport design, and Contractor-Furnished Equipment (CFE) edge compute configuration at Operations Centers to ensure continuous data synchronization and Continuity of Operations (COOP).

•

Modern Software & Modular Open System Architecture (MOSA): Architecting looselycoupled microservices architectures.

•

Common Development Environment (CDE) & DevSecOps Automation: Developing and operating scalable CDEs/Software Factories with automated CI/CD pipelines. This
