The Guardian — A Simple Box

Caylym's Guardian system enables hundreds more available aircraft to join the fight against wildfires, from the air, twentyfour hours a day.

Using well established cargo delivery procedures, the Guardian allows formations of aircraft to attack wildfires safely, from higher altitudes, at lower cost.

The Guardian is a significant advancement in Aerial Firefighting. Caylym’s development team, based in Fresno Ca., has designed a patented firefighting system that is simple and universal. The Guardian is an 8-ply, continuously wound corrugated container that holds 264 gallons or 1000 liters of liquid. Unlike other systems, no aircraft modifications are required to use The Guardian.

This advanced system is deployed using the well-established Container Delivery System (CDS) procedures from any rear-loading cargo aircraft. Each Guardian releases its contents below and behind the aircraft in an overlapping pattern creating an instant and accurate rainstorm. The Guardian has demonstrated the ability to deliver a payload designed for a direct attack or for laying a long, consistent, solid line for retardant.

An Aerial Firefighting Fleet

— When You Need It

Using existing military aircraft, The Guardian expands a country’s aerial firefighting capabilities without the need to perform any aircraft modifications. Local and national governments no longer need to maintain and store a single-mission firefighting fleet. For example, the United States only has a dozen or so high capacity water bombers, yet the ANG has hundreds of military C-130s capable of delivering the Guardian. These military aircraft, operated by State Air Guard Units, can serve their home or neighboring states in times of need. This potential aerial firefighting fleet is operated and maintained by the ANG and is mission ready.

Fast, Smart, Cost Effective Deployment

— Where You Need It

The Guardian can be assembled, filled and loaded in minutes with just two workers. Though the Guardian is 100% recyclable and 90% biodegradable each individual Guardian unit and its components remain tethered land inside the drop zone for easy clean up. Units can be collapsed into their space saving shipping configuration and recycled.

There Is A Better Way

  • No airframe modification on any aircraft is required to accommodate the Guardian.
  • The Guardian can be dropped from any rear-loading aircraft including:
  • C-27J, C-130, and C-17, C-295, CN-235, C-123, CV-22, CH-47, CH-53
  • The Guardian transforms rear-loading cargo aircraft into a firefighting platform.
  • Units hold 264 gallons (1,000 liters) of liquid (fresh/salt water, gel, foam, and retardant).
  • A C-130 carrying 16 units can drop any combination of units or the entire cargo, increasing flexibility and utility of each sortie.
  • Crews use standard Container Delivery System (CDS) procedures to deliver the Guardian.
  • Aircraft can fly and release payload at higher altitudes if safety is a concern.The ability to release payload at higher altitudes may allow for day and night operations.
  • Currently, aircraft start/stop flying during dawn/dusk.
  • Using CDS procedures increases aircraft and crew safety.
  • Delivery profile ‘gentle’ on aircraft.
  • Empty, tethered boxes fall in the drop zone.
  • The Guardian’s coverage delivers the payload at or above industry requirements.
  • The Guardian releases contents below and behind the aircraft eliminating liquid contact with the airframe reducing cleaning and maintenance costs.
  • 7 Guardian can lay out a line 550 x 65 meters.
  • The Guardian’s 8 layer, wound sidewalls lack any seams or joints and provide a solid, reliable container.
  • The Guardian weighs 105lbs empty and can easily hold 2400+lbs; a 23:1 one liquid to system weight ratio.
  • The Guardian contains no metal, pyrotechnics, sharp edges, seams or weak spots
  • Each unit requires only 2 workers and minutes to assemble, fill and load. No specialized hardware or skill required.
  • The Guardian ships in a collapsed configuration to minimize shipping and storage footprint.
  • 90 Guardian can be shipped in a 80ft container.
  • The Guardian can be prepositioned in high risk areas for quick response.

To ensure readiness of the Air National Guard, the National Guard Association of the United States supports:

  • “Highlight the need to the Interior Department and the Forest Service for development of additional fire fighting systems”
  • “Development and procure new system to disperse fire retardant and airdrop capability generic to all C-130 units. This capability would ensure that all C-130s could contribute to the Fire Fighting mission.”
  • “Codify the operational firefighting mission in Title 32”
  • “Provide survivor benefit parity between Title 10 and Title 32”
  • “Adjudicate firefighting services by allowing immediate employment of Modular Aerial Fire Fighting”

“Phase I National Air Tanker Study (NATS) Recommendation: A national fleet of 41 large airtankers (greater than 1000 gallons)”

  • The Guardian transforms hundreds of rear-loading aircraft into large airtankers without the need for airframe modification. For example a C-130 can deploy 16 Guardians with a total of 4224 gallons of liquid.
  • Since the Guardian can be used by the ANG the need to purchase additional, modern aircraft and aircraft for spare parts is addressed since the ANG aircraft are maintained at the highest standards.
