Being designed for military purposes, it is not a kerosene based fuel.
Developed to be a gas turbine fuel for cruise missiles,[1] it contains mainly exo-tetrahydrodicyclopentadiene (exo-THDCPD) with some endo-isomer impurity.
[3] Exo-THDCPD is produced by catalytic hydrogenation of dicyclopentadiene and then isomerization.
[5] Since the lack of volatile methylcyclohexane makes its ignition difficult, a separate priming fluid PF-1 with about 10-12% of this additive is required for the engine start-up.
The high energy density of 39.6 MJ/L makes it ideal for military aerospace applications - its primary use.
