This is a Request for Information (RFI) for market research only and does not constitute a solicitation or a promise of a future contract. The US Army seeks information on potential solutions for the Maneuver-Short Range Air Defense (M-SHORAD) Increment 4 system, a mobile air defense capability to protect dismounted forces from drones and aircraft. The desired solution is a vehicle-agnostic, pallet- or SLED-based system that is C-130 transportable, uses a Modular Open Systems Approach (MOSA), and provides strong government intellectual property rights. The Army is interested in solutions that could deliver capabilities in the near- to mid-term, specifically targeting the FY27-29 timeframe. No specific budget or location for performance is detailed in this notice.
