Firefighting, CO2 bomb maybe?

A couple of years ago, a firm was working on research and development of a Tomohawk-style cruise missile that would be filled with water and/or fire retardants. The missile would navigate via GPS and detonate over forest fires, dispersing its payload and putting out the flames. Initial estimates put the cost of such a device at $400,000 per unit. Not too bad when you stop and consider that the initial cost of a modern fire engine is $400,000 plus an additional $6,000,000 to staff and maintain for 20 years. These firefighting cruise missiles could, in theory, be prepped once and kept in a launch facility until the time comes to deploy them.

Some feel that wildfire fighters could also utilize high explosive bombs to crater areas around an uncontrolled blaze, denying a fire the fuel it needs to cross that barrier. This is already done by hand--back burning--but it time consuming and can be dangerous to the firefighters.

Jam it back in, in the dark.
