2026.06.03 AMEND 0001 - REVISE TITLE TO: Request for Information (RFI): Fire Control Sensor Market Availability 1. Introduction The United States (U.S.) Army Contracting Command-New Jersey (ACC-NJ), Picatinny Arsenal, NJ 07806-5000, on behalf of U.S. Army Combat Capabilities Development Command (DEVCOM) Armaments Center (AC), is conducting market research to identify potential sources for a sensor system capable of tracking both outbound projectiles (7.62mm, .50 cal) and inbound threats from small Uncrewed Aircraft Systems (UAS) (Group 1 and 2). This RFI is being issued to gather information on existing concepts and technologies that can meet this need. The ideal solution will be small, lightweight, and affordable. The proposed sensor, which may include radar, Electro-Optical/Infra-Red (EO/IR), or other active/passive technologies, must be suitable for both stationary and on-the-move operations. It should be configurable for mounting on a variety of Army ground combat vehicles, including: High Mobility Multipurpose Wheeled Vehicle (HMMWV) Bradley Fighting Vehicle Stryker Abrams Tank Joint Light Tactical Vehicle (JLTV) Next-Generation Combat Vehicles ITAR RESTRICTION NOTICE: The subject matter of this RFI may be considered a “critical technology” and is therefore subject to International Traffic in Arms Regulations (ITAR) restrictions. DISCLAIMER: For Informational Purposes Only This notice is for market research and is NOT a Request for Proposal (RFP). This RFI does not constitute a solicitation or a commitment by the U.S. Government. Responses are not offers, and the Government is under no obligation to award a contract or provide funding for any information submitted. All participation is strictly voluntary, and no funds are available to pay for the preparation of responses. 2. Technical Requirements The following outlines the minimum (Threshold) and desired (Objective) capabilities for the sensor system. Inbound Threat Tracking Threshold (Minimum) Requirement: The system must be able to search, detect, and track multiple inbound Group 1 & 2 UAS while the vehicle is on the move. This capability must be provided without any external cue. A self-cuing system with an alert/cue mode or sensor, coupled with a higher accuracy tracking mode or sensor, is an admissible solution. The optimal angular search region is 360° in Azimuth and 60° or more in Elevation; achieving this with multiple, limited-coverage sensors on the same platform can be a solution, depending on size and cost. For the purposes of this RFI, “on the move” is defined as the vehicle traveling with constant linear motion on a flat roadway at speeds up to 35 mph. The response should comment on the system's capability to accept external INS data and operate under conditions of both moving platform and remote weapon system kinematics. Objective (Desired) Requirement: The system should independently detect threats without an external cue and provide the required information to the s…
