The Admiral Grigorovich class (Фрегаты проекта 11356Р/М) is the latest class of frigates ordered by the Russian Navy for the Black Sea Fleet. Six ships (two batches of three ships) have been ordered so far to be built by the “Yantar” shipyard in Kaliningrad. The frigates are based on the Talwar-class frigate, six of which were ordered by the Indian Navy and were built at the same shipyard. The Talwar class is in turn based on the Burevestnik-class frigates. The contract for the construction of three frigates is to be completed in four years. The lead ship, Admiral Grigorovich was laid down on 18 December 2010 and was expected to be in service 34 months from that date (October 2013).
The class’s original gas turbines were made by Ukrainian state-owned enterprise Zorya-Mashproekt. The company was a center of Soviet maritime gas turbine design and production. The last three vessels remain without engines as of November-December 2014.
After the Russian seizure of Crimea and incursions into Donetsk/Luhansk, Ukraine would no longer supply the engines.Instead Russian manufacturer Saturn was initially asked to supply alternative M90FP turbines. However these cannot be completed before 2019-2020, and this delay seemingly means the Navy would rather use the funds elsewhere. Thus Russia is now hoping to find an export customer for the final three vessels. The Defence Ministry is reallocating the money, initially set aside for the other three frigates, to the construction of other ships it badly needs.

The Admiral Grigorovich Class frigates can be deployed in anti-surface warfare (AsuW), anti-submarine warfare (ASW) and anti-air warfare (AAW) missions, and are capable of conducting missions as a single vessel as well as a part of task force.
The Russian Ministry of Defence signed two contracts with Yantar Shipyard between 2010 and 2011 for the construction of six Project 11356 frigates. The keel of the first ship in series, Admiral Grigorovich, was laid down in December 2010 and the vessel was floated out of dry-dock in March 2014.
Russian Navy receives first Admiral Grigorovich-class frigate
The Russian Navy has finally commissioned into service the lead ship of its Project 11356M frigate class, Admiral Grigorovich , over two years behind schedule.
A formal flag-raising ceremony was held at the Yantar Shipyard in Kaliningrad on 11 March, over five years after the vessel was laid down in the same shipyard in December 2010. The vessel is now expected to transit to join the Black Sea Fleet in Sevastopol.
Since it was launched in March 2014, the frigate has been undergoing sea trials in the Baltic and Barents seas. Speaking at the flag-raising ceremony, Igor Ponomarev, vice president of United Shipbuilding Corporation (Yantar’s parent company), said that the vessel had “successfully passed all tests and showed the high quality of its construction”. Ponomarev added that the second and third ships of the class, Admiral Essen and Admiral Makarov , will also be commissioned in 2016. Read rest of article HERE

A dual-mode solid-propellant rocket motor provides the missile with a maximum speed of Mach 4.5. Data @wikiwand.com
|9M39 missiles (SA-18 Igla)|
|The 9M39 missile employs an IR guidance system using proportional convergence logic. The new seeker offers better protection against electro-optical jammers; the probability of kill against an unprotected fighter is estimated at 30-48%, and the use of IRCM jammers only degrades this to 24-30%.|
|9M342 missiles (SA-24 Grinch Iglas-S)|
|The effectiveness of the 9M342 missile against air targets is attributed to the increase weight of the explosive in the missile’s warhead and to the impact/proximity fuze enabling the missile to kill the target both in the event of a direct hit and when it passes at a distance of up to 1.5 m from the target. The target engagement has increased to 6 km compared with the 5.2 km of the Igla (SA-16 / SA-18) system.|

The 53-65 torpedo family are Russian made, wake-homing torpedoes designed to destroy surface ships. The 53-65 became operational in 1965, while the 53-65K and 53-65M both became operational in 1969. The 53-65KE is an exported version. China received an unknown number of 53-65KE torpedoes from Russia after purchasing 4 Kilo class submarines in the 1990s.
The Type 53 torpedo is carried by almost all Russian submarines, including the Kilo class and the Akula-class submarine.
The Type 53-65 torpedo is considered especially threatening by the United States Navy because they do not respond to usual torpedo countermeasures. Normal countermeasures are decoys that use noise to divert homing torpedoes, but the Type 53-65 uses sensors that detect the churn made by ships moving, then follows the chopped water in an S-pattern between the wakes until impact from up to 11.8 mi (19.0 km; 10.3 nmi) away. Wake homing torpedoes have caused the U.S. Navy to develop the Surface Ship Torpedo Defense (SSTD) system that employs a maneuvering Countermeasure Anti-Torpedo (CAT) that seeks and intercepts an incoming torpedo.

Fregat-M2EM air/surface search radar
The Fregat, Top Plate and Top Steer NATO codename, is a family of 3D, 360-degree/full-coverage ship-based radar systems developed for the Soviet Union Navy and designed to provide surveillance and detection of surface and airborne targets and to deliver target designation data to weapon systems. The Fregat radar system can operate effectively in intense jamming and countermeasures environments. Moreover, the radar system also provides identification friend or foe (IFF). The Fregat radar system has been provided to aircraft carrier, amphibious assault, frigates, cruisers, destroyers and special purpose class ships commissioned by the Russian Navy such as Kuznetsov, Neustrashimy, Krivak III, Kirov, Slava, Udaloy and Sovremenny.
The Fregat family of radar systems features automatic target tracking and built-in self-diagnosis system. The radar system is made of line replaceable units that can be removed with ease in the event of a malfunction. The radars developed under Fregat family are tailored for a variety of ships depending on their displacement and purpose. The main differences among them are: air surveillance range, number of channels and frequency bands, and weight. Typically, Fregat radars operate in the E-band excepting the lightest Fregat MAE-4k which operates in the H-band. All variants can detect a surface ship at the line-of-sight while the maximum detection range for an airborne target with the radar cross section of a non-stealth fighter aircraft varies from 58 to 230 kilometers.
The Fregat M2EM radar system is intended for medium and large displacement ships. It is an E-band two-channel radar with a maximum instrumented range of 300 kilometers and a maximum vertical detection range of 30 km. Fregat M2EM can detect a fighter aircraft at a maximum range of 230 km and/or a missile at a maximum range of 50 km. The radar’s equipment and the antenna station weigh approximately 11.75-t (9.25-t and 2.5-t respectively).

3Ts-25E target designation radar is designed to provide ECM-resistant secure information on long-range surface (and partly air) tactical situation using active and passive assets. The radar accomplishes the following tasks:
- acquisition and automatic tracking of sur-face targets, determination of their coordi-nates and movement parameters;
- air/surface target detection, classificationand location based on their electronicequipment emissions;
- target identification by means of coupledIFF interrogators;
- generation and transfer of target designa-tion data to ship’s automated missile/torpe-do weapons control system, and surface sit-uation data to combat information manage-ment system;
- interaction with external data sources (e.g.task force ships, air reconnaissance/designa-tion systems, etc.) via ship’s standard andspecial communication systems integratedwith the radar as specified bythe ship designer;
- operation in the navigation mode to ensuresafety of navigation.
The radar makes coordinated use of active and passive channels to acquire and designate targets. It boasts increased operational range thanks to employment of high-energy active channel, advanced methods of signal genera-tion and complex modulated signal process-ing, coupled with passive channel data, and requirements of covert operation, in severe ECM and sea clutter conditions.
The active channel uses a multiprocessor system to generate probing signals and radar data. It is integrated with a multi-computer secondary data processing, control and display network.
The passive channel performs hard-ware/software-based analysis and classification of incoming radar signals by comparing their parameters with those available in the data-base (up to 1,000 entries).
