C-sUAS 4925 RFFE Retrofit

Background
The contract is issued by the National Guard Bureau (NGB) for the procurement of the 4925 RF Front End Retrofit specifically from Black River Systems Company. The NGB's mission includes providing operational support to the United States Air Force (USAF) and Air National Guard (ANG).

The goal of this contract is to update the RFFE for the NINJA system, which is currently the program of record for Counter-small Unmanned Aircraft Systems (C-sUAS) capability. The legacy RFFE model has become outdated due to supply chain issues impacting warranty and maintenance contracts, as well as reduced engagement capability compared to the new model. Black River Systems is identified as the sole manufacturer of this device for the NINJA system.

Work Details
The specific item to be purchased under this contract is the 4925 RF Front End Retrofit. This retrofit is essential for maintaining and enhancing the capabilities of the NINJA system. It must be procured exclusively from Black River Systems Company as per NGB A4S Memo dated June 7, 2024.

Place of Performance
Newington NH 03801 UNITED STATES

Bidder Requirements
The opportunity is set aside for Small Business Set Aside - Total (SBA). Bidders must be authorized distributors or manufacturers of Black River Systems products.

Incumbent Analysis (see Incumbents section for more detail)
The prior awards indicate a confirmed incumbent, Black River Systems Company, with multiple NGB contracts for NINJA RF Front End Retrofit and related sustainment. For example, Black River Systems received awards valued at $187,463 (09/30/25–04/30/26) for “NINJA SOFTWARE, SUSTAINMENT AND RFFE UPGRADE,” $174,265 (09/29/25–09/29/26) for “NINJA SYSTEM RADIO FREQUENCY FRONT END RETROFIT” including 1-year sustainment warranties, and $82,999 (09/06/24) for an “RF FRONT END RETROFIT” upgrade to an existing NINJA system. These efforts appear to align closely with the current requirement to procure the 4925 RF Front End Retrofit for the NINJA C-sUAS program as a continuation of prior RFFE retrofit work.
