Iran's Kilo submarines reportedly unable to stay submerged

According to several corroborating sources, the 3 type 877 EKM Kilo submarines acquired by Iran from Russia in 1991, and modernized in 212 by Iran, would no longer be able to remain submerged beyond a very short time, forcing submersibles to navigate with a snorkel the majority of the time. In fact, their batteries have reached their limit of potential, and should have already been replaced several years ago. However, Russia maintains the international arms embargo against Tehran, preventing the Iranian authorities from obtaining spare parts, including batteries.

In addition, Iranian engineers seem not to be able to master the complex technology of heavy submarine batteries, such as the Kilo. Thus, tests this spring led to the death of 3 engineers when the battery tested exploded.

The Kilo submarines probably represented the most significant naval threat to Iran in the Persian Gulf. Their inability to maintain a sustained dive therefore represents excellent news for Western naval forces responsible for protecting commercial traffic in the area.

This information, which must however be confirmed before being taken as a guarantee, also shows the limits of Iranian engineering in certain key areas, as well as the crucial role that modern battery technology represents today for strategic autonomy. of a country. Indeed, beyond submarines, batteries are used in a wide range of equipment, ranging from communication systems to drones.

It remains to be seen whether Iran will not succeed in acquiring these batteries from other countries, such as North Korea or China, which have already provided the country with critical missile and radar technologies.
