The Project 877EKM is equipped with a combat information system consisting of a multi-purpose MVU-110EM computer which allows for five targets to be tracked simultaneously, with two automatically and three manually. The Andoga navigation system feed the course and speed data into the combat data system.

The Project 636 features an improved C4ISR system with a high speed computer capable of processing information from the surveillance equipment and display it on the screen. It can also automatically determine the surface and underwater target data and calculate firing parameters, provide automatic fire control, and provide information and recommendation on the manoeuvres and deployment of weapons.

The Project 877EKM is fitted with a MGK-400 Rubikon (Shark Teech) dual-channel sonar providing echo target ranging, detection of active sonar signals, and underwater communication. The Project 636 has an improved MGK-400EM digital sonar with better performance.

The submarine is also fitted with an MRK-50 (Snoop Tray-2) active surface search radar working in periscope and surface modes to provide information on the underwater and air situation, radar identification, and navigational safety.

Countermeasures include electronic support measures (ESM), radar warning receiver and direction-finder.
