A formulation and methods for making high energy organic fuels that incorporate suspended metal particles with metal particle sized ranging from 33 nm to 5 micron. The hybrid organic fuels contain superior density and/or energy content to conventional liquid organic fuels. These hybrid organic fuels used in combination with metal particle afford fuels with 5 to 80% more net heat of combustion (based on volume). These fuels should extend the distant range for jets, liquid rocket engines, SCRAM jet engines, and improve energy content in fuel-air explosive applications such as fuel-air explosives and in the Multi-Effects Weapons System (MEWS) where the fuel is used both for propulsion and explosive effects.
