Twin Agent Unit Fire Fighting System for the River Class Destroyer

The Twin Agent Unit (TAU) is a self-contained dual-agent firefighting system designed for rapid response to helicopter crash incidents aboard the River Class Destroyer, requiring the simultaneous or independent discharge of Purple-K dry chemical and a non-fluorinated foam (F3) without dependency on shipboard utilities. The system must be installed with two independent hose reel stations—one forward in the hangar and one aft below the flight deck—to ensure full operational coverage of the flight deck and surrounding areas, with manual operation feasible by a single firefighter wearing full protective gear. Performance requirements include extinguishing a 3,000 square foot flammable liquid fire within 90 seconds, delivering foam at a rate of approximately 227 liters per minute with an effective range of 6 to 12 meters, and discharging dry chemical at 2.27 kilograms per second with a minimum range of 8.2 meters, maintaining simultaneous agent discharge for at least two minutes per station. All components must meet stringent naval environmental standards, including MIL-DTL-901E Grade A for shock resistance and MAP 01-470 Class 1 Zone C for vibration and noise, and comply with NFPA 11 and NFPA 17 for firefighting system design. The system must be designed to endure crash-on-deck impacts and operate reliably in harsh maritime conditions, with proprietary foam stored in pressurized nitrogen cylinders allowing for replenishment. The procurement is being conducted under solicitation number W847S-25DR061 by the Department of National Defence of the Government of Canada as a Request for Information (RFI), not a formal solicitation or contract, meaning no pricing, award criteria, or delivery schedule has been established. Submission of technical responses is required by May 30, 2026, at 4:00 PM EST via email to Felix D'Aoust, the designated point of contact, and must include detailed diagrams, Bill of Materials, performance test data, and evidence of compliance with all referenced standards. Proprietary information must be clearly labeled, and all submissions are subject to Canada's Access to Information Act. No Industrial and Technological Benefits obligations apply, nor are there requirements for security clearances, key personnel, or socioeconomic certifications. The place of performance is aboard RCD vessels under construction in Canada, with no packaging, preservation, or marking specifications beyond general confidentiality labeling, and no invoicing, payment, or accounting details are provided as the
