The underwater detonation of explosives has been modeled using the one‐dimensional code SIN. Conditions for the modeling are carefully chosen so that equilibrium product isentropes calculated with BKW equation of state can be used with enough accuracy. The characteristics of the shock wave and gas bubble pulsation are used for the evaluation of underwater energies. Values of the shock wave and bubble parameters obtained, and of the shock and bubble energies, are compared with data available from literature for both ideal and non‐ideal explosives. The modeling appears to be able to predict fairly accurately the underwater energies of explosives with quasi‐ideal behavior, while it overestimates energies of non‐ideal compositions, particularly the shock energy.
