List of stoffs

During World War II, Germany fielded many aircraft and rockets whose fuels, and oxidizers, were designated (letter)-Stoff. The following list of stoffs refers to the World War II aerospace meanings if not noted otherwise.

Meaning of stoff[]

The German word Stoff (plural Stoffe), like the English word stuff, derives from Old French estoffe, however the meanings are somewhat different. Stoff has a fairly broad range of meanings, including "chemical substance" or "matter", "fuel" and "cloth", depending on the context.^[1] The German names of the common elements hydrogen, oxygen and nitrogen are Wasserstoff, Sauerstoff and Stickstoff ("hydrogen" being a scientific Greek neologism for "constituent of water", "oxygen" for "constituent of acids", "nitrogen" for "constituent of nitre", i.e. saltpeter). Stoff was used in chemical code names in both world wars. Some code names were reused between the wars and had different meanings at different times; for example, T-Stoff meant a rocket propellant in World War II, but a tear gas (xylyl bromide) in World War I.
