Originally, the Martin Mars flying boats were produced for the US Navy and were used as troop and cargo transports among the islands of the Pacific. Firefighting certainly wasn’t what the aircraft’s manufacturer, Glenn L. Martin had in mind. however, all four aircraft, the Marianas, Philippine, Hawaii and Caroline Mars were ferried to British Columbia where three were fitted with 7,200 gallon (27,276 litres) water tanks and converted to waterbombers!
Flying Tankers operate on the philosophy of “gallons per hour”. Simply stated, this means a direct assault on the fire by dropping the largest possible amount of water or gel in the shortest possible time. This philosophy, combined with the Mars excellent initial attack and outstanding ability for sustained operations are the keys to our success – they are scoopers and, working in tandem, they are able to deliver 14,000 US gallons (54,500 litres) of suppressant for the initial attack and continue delivering as much as 7,200 US gallons (27,276 litres) every seven minutes thereafter in sustained operations if needed.
