Our recent editorial lambasting the Fox Trot Alpha article on the Civil War Tank got us thinking about steam power and tanks. While steam is certainly not the ideal way to propel a tank, it has been looked at a number of times, and as recently as the 1960’s. The document “Engine-Transmission Power Plants for Tactical Vehicles” by the Research Analysis Corporation from 1967 includes a chapter on steam power for military vehicles. It’s a relatively short chapter but it makes for interesting reading. We have reposted it below as individual images, or it can be downloaded as a PDF file here: Steam engine tanks.
