REINVENTING HOW
WE FIGHT WILDFIRES

We depend on aerial fire retardants to slow the spread of flames and to give firefighters on the ground the tactical advantage they need to move into position and fortify fire barriers. The continual increase in wildfire activity in the western United States has seen a proportional increase in the amount of retardant that’s required to keep fires at bay. Now, with tens of millions of gallons dropped every year, the chemical content, efficacy, and environmental impact of fire retardants is more important than ever before.

A Giant Leap Forward
in Retardant Technology

Fire retardant technology is overdue for an upgrade. Environmental researchers have known for a long time that industrial fertilizer doesn’t belong on our wildlands or in our natural water systems, but it has been the only long-term fire retardant fully qualified for use by the United States Forest Service. We’re working hard to change that. Fortress fire retardants are based on an entirely new formulation that provides superior fire control while eliminating the harsh environmental side effects of fertilizer-based retardants.

COMPREHENSIVE FIRE Protection

When we started Fortress in 2014, we started with a simple problem statement: can we develop an alternative fire retardant that’s more effective and better for the environment? Through extensive research, lean product development and rigorous testing, we’ve answered with a comprehensive offering of innovative retardant formulas for aerial attacks, utility applications, residential defense, and commercial protection.

Products

Our first-generation aerial formulations have recently passed the full battery of laboratory tests performed by the U.S. Forest Service (USFS) at its Missoula laboratory facilities, making Fortress the only new entrant in over two decades to achieve placement on the USFS Qualified Products List (QPL). Our unique chemical formulations bring new features to the frontlines of firefighting.
