Although the term "operational research" was not coined until 1938, this application of science and engineering to sound ranging and flash spotting in 1914-18 certainly established the spirit of this emerging discipline. At the same time, sound ranging will practically not be able to ensure the sufficient accuracy of coordinates for intensive artillery fire in the course of a combat operation; aerial reconnaissance will not ensure the prompt presentation of data for missile forces and long range artillery (it takes at least four hours to process aerial imagery), while the determination of the coordinates of highly mobile targets will be almost impossible. Advanced sound ranging also detected enemy artillery fire to an accuracy of about 100 meters at a range of 60 kilometers. |
