LF2/Ammonia Liquid Fluorine is the highest performance oxidiser and in the early 1960's it seemed in both American and Russia that a new generation of higher performance engines would emerge. However although test engines were built, fluorine was found to be just too toxic and reactive to be safely used as a propellant. Ammonia (NH3) is a colourless gas and liquid with a strong irritating characteristic odour. More...
