The Project 11356P Admiral Grigorovich-class frigates represent a formidable addition to the Russian Navy’s surface warfare capabilities. These multi-purpose guided missile frigates have been designed to undertake a wide range of missions, including anti-submarine warfare, anti-surface warfare, and anti-aircraft warfare. Their advanced systems and armaments make them versatile assets for both bluewater operations and littoral environments.

Armament

Kalibr (SS-N-27 Sizzler) cruise missile

The Admiral Grigorovich-class frigates are equipped with an array of powerful armaments. One of their primary weapons systems is the Kalibr (SS-N-27 Sizzler) cruise missile, which can engage targets both on land and at sea. The Kalibr missile has a range of up to 2,500 kilometers and can carry either conventional or nuclear warheads. With its long-range and precision capabilities, the Kalibr missile provides the frigates with significant offensive firepower.

In addition to the Kalibr missiles, the frigates carry an assortment of other weapons. They are armed with anti-submarine torpedoes, which can be launched from their onboard torpedo tubes to engage submarines. The frigates also feature anti-aircraft missiles, providing them with defense against aerial threats. These missiles are capable of engaging aircraft, helicopters, and unmanned aerial vehicles (UAVs). Furthermore, a 100mm main gun is installed on the frigates, which serves as their primary naval artillery for engaging surface targets.

Sensors and Systems

The Admiral Grigorovich-class frigates are equipped with advanced sensor systems, enabling them to effectively detect and track targets in various environments. These frigates feature long-range surveillance radars for air and surface target detection, allowing them to identify and track threats from a considerable distance. They also have surface search and fire control radars for precise targeting and engagement of surface vessels.

In terms of underwater detection, the frigates utilize advanced sonar systems. These sonar systems include hull-mounted sonars for detecting submarines and bow-mounted sonars for detecting underwater obstacles. The frigates are also equipped with towed array sonars, which can be deployed behind the ship to enhance their submarine detection capabilities.

To enhance their situational awareness and electronic warfare capabilities, the Admiral Grigorovich-class frigates feature electronic support measures (ESM) systems. These systems enable the frigates to detect and analyze enemy electronic emissions, providing valuable intelligence and aiding in the identification of potential threats. Additionally, the frigates are equipped with electronic countermeasures (ECM) systems, which can disrupt or deceive enemy radar and communications systems.

Propulsion

The propulsion system of the Admiral Grigorovich-class frigates combines gas turbine and diesel engines, providing a balance between speed and endurance. They are equipped with gas turbine engines for high-speed operations, allowing them to reach speeds of up to 30 knots (approximately 56 km/h). The frigates also have diesel engines, which are more fuel-efficient and provide greater range for extended patrols. At a cruising speed of 14 knots (approximately 26 km/h), the frigates have a range of approximately 4,850 nautical miles (approximately 9,000 kilometers).

Crew and Accommodation

The frigates have a crew complement of around 200 personnel, including officers and enlisted personnel. They are designed to provide comfortable living conditions and facilities for extended operational deployments. The frigates feature modern living quarters for the crew, including cabins and berths. They also have mess areas for dining, medical facilities for providing healthcare services, and storage spaces for supplies and equipment.

Export Variants

In addition to serving in the Russian Navy, the Admiral Grigorovich-class frigates have also been exported to other countries. For instance, India has acquired four frigates of a modified variant known as the Talwar-class frigates. These frigates incorporate certain Indian-specific modifications and enhancements while retaining the core capabilities of the Admiral Grigorovich-class.

The Admiral Grigorovich-class frigates have emerged as formidable naval assets, contributing to the Russian Navy’s maritime capabilities. With their advanced armaments, sensor systems, and propulsion, they can undertake a variety of missions effectively. These frigates serve as potent platforms for long-range strike capabilities, anti-submarine operations, and air defense, bolstering the operational capabilities of the Russian Navy and its partner nations.
