The domestically developed supercavitating torpedo, unveiled for the first time at the 2025 Maritime Defense Exhibition! Let's explore the hidden technology behind this supercavitating torpedo, which is more than twice as fast as a standard torpedo. The Soviet Union, the first to develop supercavitating torpedoes! The Soviet supercavitating torpedo, the Shkval, realized the innovative concept of creating an air layer on the surface of the torpedo. It boasted an incredible speed of 400 km/h, but it failed miserably in practical application. What was the reason? The solid rocket propellant used as fuel for supercavitating torpedoes. It is said that water is used instead of an oxidizer to keep the fuel burning underwater... but how is that actually possible? The speed of the domestically developed supercavitating torpedo, as revealed by the Agency for Defense Development, is approximately 185 km/h. While this speed is lower compared to previously released supercavitating torpedoes, the reason for lowering the speed is not actually a lack of technological capability, but rather due to various strategic intentions.
