The Project 677 submarine is designed to engage surface and underwater combatants in the assigned area, strike land targets by cruise missiles, and sustain littoral anti-submarine defense.

The ship is 68 m long and has a submerged displacement of 2,650 t. The submarine features a full underwater speed of 21 knots and a surface range of 6,000 nautical miles at a speed of 7 knots.

The combatant is armed with six 533 mm torpedo launchers and has a 37-strong crew. Unlike underwater combatants of previous generations, the Project 677 submarine can fire cruise missiles in salvo mode against sea targets.

The ship is fitted with a modern combat management system, cutting-edge sonar unit, new anti-sonar coating, and externally mounted extendable subsystems.
