Long-Range Guns

Nature volume 101, pages 8485 (04 April 1918) | Download Citation



THE appearance of a gun with a range of something like seventy or eighty miles has naturally aroused considerable interest, and the question is often asked as to how such long ranges are attained. The answer is that if the shot is to travel far it must get outside the atmosphere, or rather to a height where the density of the air is very small, and that it must be started with such a velocity that in spite of the air resistance in the first part of its course, its remaining speed, after having reached the upper air, shall be sufficient for its further progress.
