Prior to WWI, American military scientists projected ideas of what weapons would be used in the upcoming conflict.
Since battles would be fought on land, in the sea and up in the air, there were many ideas about what new technologies would emerge and be used in the fight to dominate other nations.
Scientific American published these images originally in 1913 and again last week.
We have compiled these images into a PDF ready for your classroom use.
