Abstract: A firing circuit that is used for a lightweight launcher for propelling rets is disclosed. The firing circuit generates a pulse for firing the rocket launcher and comprises first and second capacitor banks. The first capacitor bank acts as low impedance energy source, in which power is developed to supply sufficient energy to initiate the rocket motor squib which, in turn, ignites the rocket motor of the rocket. The second capacitor bank acts as a high voltage, low impedance source whose energy is used to charge a capacitor internal to the rocket. The capacitor internal to the rocket, is part of the rocket warhead fuse. The capacitor internal to the fuse is used to initiate the detonator of the rocket warhead when the rocket terminates flight at target.
