Simplex unveiled its newly developed 850-gallon internal Fire Attack system for the Black Hawk (S-70i, S-70A, UH-60A and UH-60L) at the Tangent Link Aerial Firefighting North America conference held at McClellan Airfield in Sacramento, California.

The 850-gallon internal tank utilizes a single dispersal door that drops water through the cargo hook well with minimal modifications to the aircraft. Installing the tank in the aft cabin increases the depth of the water, compared to belly-mounted tanks, provides a powerful gravity fed water drop.

Simplex also offer a 1,000-gallon internal Fire Attack system with three dispersal doors requiring minimal modifications to the aircraft skin. Both internal tanks systems are made from lightweight composites providing superior corrosion and fatigue resistance compared to historic metal tanks providing decades of maintenance-free operational service.

Both the 850- and 1,000-gallon models use a 1,000 gallon-per-minute hover refill system capable of being mounted on either side of the tank. Each model has dual ground fill ports, so the tank can be easily refilled when circumstances required ground fill and during night operations. The entire Fire Attack system can be installed or removed in less than 15 minutes, according to Simplex.
