Abstract : Composition H6 is a widely used main charge filling for underwater blast weapons such as mines, depth charges, torpedoes and mine disposal charges. In weapon applications, computational models require experimental data to determine certain specific output parameters of H6 to predict various underwater blast scenarios. To this end, the critical diameter dc, which is the minimum diameter which will sustain a stable detonation, and the limiting value of the velocity of detonation at infinite charge diameter D-infinity, were determined for unconfined cylinders of H6. An ionization probe technique was used to measure the velocity of detonation (V of D) of the H6 over a range of charge diameters (d).
