Rocket propellants with fluorine compounds

Propellants and Explosives. Hydrazine fuels include anhydrous hydrazine (AH), monomethyUiydrazine (MMH), and unsymmetrical dimethyUiydrazine (UDMH) for military and space programs. These compounds are used mainly as bipropeUant fuels, ie, with oxidizers, in rockets such as the Titan, MX missile, and the Ariane (UDA4H7X30. Using oxygen or fluorine as the oxidizer, hydrazine is exceeded only by hydrogen in specific impulse, ie, kilograms of thmst developed for each kilogram of fuel consumed per second (196). 

Noble Gas-Oxygen Compounds. Since the discovery in 1962 that the noble gases are not truly chemically inert, propellant chemists became intrigued with the possibility that they could serve as excellent carriers of oxygen (and fluorine) and thus generate a new family of chemical propellants. While the importance of this discovery to chemistry cannot be underestimated, so far it has not led to the preparation of new compounds as significant rocket oxidizers.
