The paper deals with an adaptation of the satndard interior ballistics model for the case of amphibious rifle firing ammunition under water. Besides, influences of the powder mass, barrel length and material of the underwater projectile on the underwater interior ballistic processes are studied. The presented mathematical model is validated and experimentally verified for the 5.56 mm underwater projectile fired from the 5.56 mm amphibious rifle. The results of this research can be applied for the design of the underwater ammunition, underwater rifle and amphibious rifle.
