FFAR rocket motors : Mk4 (fixed wings) and Mk40 (rotary wings)

Mk40 and Mk4 rocket motors are 4 Folding-Fin Aerial Rockets (FFAR) and have a double base solid propellant grain. Both are fully compatible with all available FZ rocket launchers and warheads.

The Mk4 rocket motor has been especially designed for use on fixed wings aircraft. Mk40 is very similar to the rocket motor Mk4, but for use on rotary wings aircraft.

As for all FZ rocket components, the minimum shelf life for Mk4 or Mk40 rocket motor is 10 years under normal storage specification (i.e. temperature between 10°C and 30°C and hygrometry according to FZ specification).
