330-PS-6146  (USN 708982):  U.S. Navy’s New Miniature Fire-Fighting Truck.   A miniature fire truck, capable of negotiating rough terrain to fight forest and brush fires is being added to fire-fighting equipment for naval bases and air stations.    The new vehicle, nicknamed “Ranger” is about half the size of standard Navy fire truck, and can pump 500 gallons of water a minute at a pressure of 120 pounds per square inch.  Its booster tank carries 150 gallons.  Built by Willis Motors, Inc. and Mobile Fire Apparatus, Inc., it will be tried out as a replacement at bases where buildings are widely separated and as auxiliary equipment at large installations.   During a preliminary test of a prototype model at the Naval Ordnance Laboratory the “Ranger” extinguished four separate fires in less than two minutes.  Two pairs of firemen simultaneously attacked an open pit and a tank fire each ablaze with nearly 2,000 gallons of flaming oil.  Quickly smothering these blazes, one pair then turned to blasting a brightly-burning wall filled with oil-soaked excelsior, while the other team rushed into a smoke-filled two-story building.  All four fires were out in less than two minutes.   Photograph released September 3, 1953.  (4/21/2015).
