C-sUAS 4925 (RFFE) Radio Frequency Front End

The 4925 RF Front End Retrofit is a sole-source procurement authorized under FAR 6.302-1 and supported by 10 USC 3204(a)(1), requiring purchase exclusively from Black River Systems Company due to the proprietary nature of the NINJA counter-small Unmanned Aircraft Systems (C-sUAS) platform. The legacy Radio Frequency Front End has become obsolete due to critical supply chain disruptions that have compromised warranty and maintenance support, resulting in degraded operational capability. Black River Systems is the sole manufacturer capable of providing the 4925 RFFE Retrofit Kit, which is essential to restoring full mission effectiveness for the USAF and Air National Guard’s program of record. The procurement is justified by the NGB A4S Memo dated 7 June 2024, which confirms no alternatives exist due to technical integration dependencies, proprietary design, and lack of viable substitutes. The contract is structured as a Firm Fixed Price arrangement with no competition, no evaluation factors beyond sole-source eligibility, and no pricing details disclosed. The place of performance and delivery is Birmingham, Alabama, with the 117th Security Forces Squadron as the requiring activity. No packaging, marking, inspection criteria, or invoicing procedures are specified, and no offeror representations, certifications, or socioeconomic status information is provided. The procurement relies entirely on the government’s sole-source determination, with no options, renewals, or additional quantities included. Funding is sourced from Operations and Maintenance, Air, though no specific appropriation or account numbers are provided. The solicitation number is W50S6M25QA023, posted on SAM.gov on June 25, 2026, and the contracting point of contact is located at W7MT Uspfo Activity Alang 117 in Birmingham, Alabama.
