The Project 636 submarines come with a double hull structure divided into multiple compartments. Among their significant attributes is the "Kalibr" missile system they are fitted with.

Another impressive feature is the rapidity with which they can recharge their torpedo tubes — a mere 15 seconds. These submarines boast impressive underwater endurance, capable of covering 400 miles at 3 knots and a whopping 7500 miles at 7 knots.

Their operational autonomy lasts up to 45 days. Adding to their stealth capabilities is their advanced navigation system that retains parameters for extended periods without necessitating correction.

In comparison to older versions, the modernized Project 636.3 submarines outclass in several aspects such as generator power, underwater speed, and submerged range.

Their ability to remain undetected thanks to low noise levels grants them the upper hand in detecting and launching preemptive strikes on enemy vessels using their anti-ship cruise missiles.

In recent history, the Russian Black Sea Fleet added six of these submarines between 2010 and 2016. Following this, the Pacific Fleet of Russia saw the addition of six submarines, with construction wrapping up in 2023.

The Navy boasts submarines from the Project 636 line, hailing from Russia. Four such vessels are part of the fleet, namely Messali el Hadj, Akram Pacha, El Ouarsenis, and El Hoggar. These submarines have been commissioned over a period spanning from 2010 to 2019.

Moving on to the Project 877EKM submarines, their origin can be traced back to the Soviet Union era. The fleet includes two of these submarines, the Rais Hadj Mubarek and the El Hadj Slimane.

These vessels, representing the original Kilo-class, made their debut in the late 1980s, with deliveries in 1987 and 1988. Not resting on the initial design, these submarines underwent a series of refits and upgrades in the mid-1990s.
