US-FED-00000385873 - MH-139 Defensive Weapon System - Deadline August 10,2026

This Request for Information (RFI) is issued for informational and market research purposes only in accordance with Federal Acquisition Regulation (FAR) Part 10. It does not constitute a solicitation, a Request for Proposal (RFP), or a promise to issue an RFP in the future. The Government will not reimburse any company or individual for expenses associated with preparing or submitting information in response to this RFI. The information provided may be used by the U.S. Air Force in developing its acquisition strategy, Statement of Work (SOW), and performance specifications. Interested parties are responsible for adequately marking proprietary or competition–sensitive information.BACKGROUND AND SCOPEThe Air Force Life Cycle Management Center (AFLCMC), MH–139A Program Office (AFLCMC/WIH), is conducting market research to identify sources capable of designing, integrating, and testing a modernized Defensive Weapon System (DWS) for the MH–139A aircraft.The objective of this effort is to upgrade the current M–240D DWS to better meet operational requirements. Proposed solutions must be rapidly acquirable, using components that are commercially available or within military supply wherever possible. The primary objective is to acquire a DWS that meets or exceeds operational requirements defined below. In order to meet requirements, the solution may modify or replace components, including but not limited to, the existing weapon, mounts, weapon cradle, and ammunition handling systems. Another significant objective is to acquire a weapon–agnostic mounting capabilitycomparable to the military–fielded Dillon Aero Huey Mount (UHMNT) to allow the interchangeable use of multiple standard DoD weapon systems; however, the Government will also consider integrated, weapon–specific mounting solutions if the proposed weapon system provides a significant tactical advantage in lethality and capacity.This effort is targeted strictly as a post–production field retrofit of the fleet of MH–139A helicopters. Technical support is expected during the initial implementation and testing of the new configuration, followed by subject matter expert support for a to–be–defined post–integration period. (For current configuration, see attachment “Figure 1: Current Configuration.“)Key requirements for the modified system include:System & Mounting ConfigurationSystem Quantity: Two (2) weapon systems per aircraft (one per side).Weapon–Agnostic Mounting: The system must feature a universal pintle mounting solution capable of supporting standard DoD crew–served weapons (e.g., comparable to the military–fielded Dillon Aero Huey Mount (UHMNT)).Structural Integration: The objective is to leverage the aircraft`s existing external weapon mounting points in Figure 1 attachment.Ammunition & LogisticsAmmunition Capacity: The system must support a continuous firing rate of at least 650 rounds per minute for at least one minute with a 30 second or less reload time.Servicing & Reload: The crew must be able to safely clear weapon malfunctions and perform full ammunition reloads both in–flight and on the ground without the use of specialized tools.Casing & Link Ejection: The system must safely expel spent casings and links overboard without causing damage to the aircraft and without the use of a collection device.Performance & OperationField of Fire: Provide a maximum field of fire in all directions without damage to the aircraft (minimum of 85 degrees forward, –85 degrees aft, 4 degrees elevation, and –65 degrees depression from the “zero“ position). The zero position is defined as the gun pointing straight out perpendicular to the side of the aircraft.Armed Configuration: The weapon must be capable of being in a fully armed (loaded and cocked) configuration with cabin windows and doors closed. Note: the weapon does not need to be fired with windows and doors closed.Power: If required, the system must be capable of using existing aircraft power and/or a separate battery power source to allow full operation both in–flight and on the ground with or without rotors turning.Lethality: Provide performance data demonstrating the hit percentage / ability to immobilize personnel and light vehicles at a minimum distance of 800 meters.Crew Interface & Airworthiness
