C-sUAS 4925 (RFFE) Radio Frequency Front End

The 117th Air Reserve Wing seeks to procure the NINJA C-sUAS 4925 Radio Frequency Front End (RFFE) from Black River Systems Company, which has been identified by the National Guard Bureau A4S as the sole manufacturer of this specialized device for the NINJA counter-small unmanned aircraft system. This pre-solicitation notice is for informational purposes only and represents an intent to make a sole source award rather than a competitive procurement. The 4925 RFFE provides enhanced counter-drone capabilities by enabling transmission and reception across multiple frequency bands (400 MHz, 900 MHz, 2.4 GHz, 5.8 GHz) in a single consolidated package, offering higher peak transmit power for more effective countermeasures and RF band agile configuration for defending against swarm and mass attack scenarios. The device replaces legacy RFFE components due to supply chain issues and reduced engagement capabilities with older models. This notice was posted on September 17, 2025, with a response deadline of September 24, 2025, though responses appear to be for informational feedback rather than competitive proposals.

No set-aside designation applies to this procurement, as it represents a sole source acquisition from Black River Systems Company, the identified incumbent and exclusive manufacturer of the RFFE component for NINJA systems. The supporting documentation indicates that the National Guard Bureau has allocated specific funding to respective Wings for procuring these RFFE devices, though no specific contract value or budget range is disclosed in the pre-solicitation materials. The procurement addresses a critical capability gap, as the legacy 284501 RFFE was fully phased out by October 1, 2023, making the 4925 model the only viable replacement option. The timeline shows that Black River Systems made the 4925 Retrofit Kit available beginning September 1, 2022, and provided it at no cost to all Gen 2 systems ordered after June 1, 2021. The device consolidates three separate Line Replaceable Units into one integrated package and includes advanced features such as Built-in-Test capabilities, remote health monitoring, and an externally accessible main fuse for enhanced operational efficiency.
