Abstract:

Hangfire problems encountered in M61 gun installations on USAF aircraft dictated the need for a moisture-indicating system which could be used to screen 20 mm ammunition. This report describes the development of such a system utilizing a color-producing reaction between ferric ammonium citrate and gallic acid. When formulated into a suitable lacquer system and applied to a cartridge case, water contamination was indicated by a color change from gray to black.
