Containerized Aerial Fire Fighting Systems (CAFFS) are airdrop-capable containers for water or fire retardants used to put out major fires.

These containers are used around the world but are not legal in the U.S. This—may soon change as David Valadao’s bill H.R. 3389, the Emergency Wildfire Fighting Technology Act has advanced in the House Natural Resources Committee.

“Wildfires have devastated California homes, businesses, and ecosystems – displacing entire communities and destroying critical infrastructure across the state. As we approach fire season, we must ensure our firefighters have every tool available to combat these deadly wildfires and protect our communities,” said Congressman Valadao.

One Fresno company, Caylym Technologies International focuses on "The Guardian," a large cardboard package that contains water or fire retardant allowing planes to drop the boxes from the sky into a fire releasing 264 gallons or 1000 liters of liquid.
