CH-47D Chinook Fire Attack System
Kawak’s CH-47D Aerial Firefighting Tank System turns the legendary Chinook into a Type 1 aerial firefighting machine. Built in collaboration with front-line operators, the system includes two FAA-certified components: the Model 41400 Aerial Liquid Delivery System (ALDS) and the Model 41300 Auxiliary Hydraulic Power System. Together, they deliver unmatched performance, speed, and operational flexibility.
With a 2,500-gallon internal tank and the fastest fill time in the industry, the system refills in under 60 seconds using Kawak’s 4000 GPM hover pump. Automated flow control, split-drop capabilities, and optional foam injection give pilots the precision they need. The system is rated for full VNE cruise, enabling high-speed ferry with the tank installed.
When priorities shift the modular design allows for rapid reconfiguration to external load ops in hours not days so you can take on more missions with fewer aircraft.
Performance isn’t the only reason operators choose Kawak.
- Because you’re not just buying a tank, you’re investing in uptime, adaptability, and gear that holds up under pressure.
- Because we listen, this system was built with operator input, not assumptions.
- Because we back what we build, with real support, fast service, and systems that are easy to maintain in the field.
Kawak products are engineered for simplicity, performance, and support. This isn’t just equipment, it’s a firefighting partnership designed to help you win the mission and keep flying.
