SS-N-26 (3M55/P-800 OniksAnti-Ship Missile


Russian MoD

The P-800 Oniks anti-ship cruise missile is a supersonic cruise missile with variants that can be deployed from land or air. Its development began in 1983, and it became operational in 2002. The missile launches from a vertical position and uses angular thrusters located near the nose to reposition itself horizontally and begin its flight path toward the target. The missile then flies at supersonic speeds, can maneuver to avoid air defense, and is resistant to electronic countermeasures. Its ground-based variant, the Yakhont, is placed on a Bastion-P road-mobile launcher as part of a coastal defense system. The Bastion-P, or a TEL vehicle, can carry two of the Yakhont missiles, which can be launched within five seconds of each other. The P-800 Oniks is primarily an anti-ship missile, but has been seeing more use against ground forces in Russia’s ongoing fight against Syrian rebels.

9M100 short-range surface-to-air missile (SAM)


The 9M100 is a short-range surface-to-air missile (SAM) being developed by the Fakel Design Bureau, part of Almaz-Antey concern, for new air defenses that should be in place within Russia by 2015. It is targeted at countering the latest generation of fighter aircraft, helicopters, cruise missiles, guided bombs, supersonic missiles and unmanned aerial vehicles (UAVs) which pose a grave threat to ground forces and key facilities. The highly maneuverable 9M100 missile is being designed for launch by means of a vertical launching system (VLS). As of early 2010 the 9M100 missile system is associated with Vityaz medium-range air defense system and might be the primary weapon for the Morfei short-range air defense system.

The 9M100 guidance system combines an inertial navigation system (INS) with an infrared seeker along with a contact and proximity fuze which ignites the warhead. Such a guidance system means that the 9M100 missile is a fire-and-forget weapon capable of engaging multiple targets simultaneously. The solid propellant rocket motor features thrust vectoring control providing outstanding maneuverability.

Length: 2.50 meter (98 inch)
Max Range: 10 kilometer (5.40 nautical mile)


9M96M, and long-range 9M96 missiles


The 9M96 is a family of advanced Surface-to-Air Missiles (SAMs) designed to engage a wide range of aerodynamic and ballistic targets in the most severe clutter and jamming environments with unprecedented effectiveness. The new missile is able to intercept targets at a maximum speed of Mach 15 (4,800-5000 m/s) and at a maximum altitude of 35,000 meters. The 9M96 missile family was developed for integration on the Russian Triumf next generation air defense system. The Russian Air Force seeks to field a 9M96 derivative designed to perform long range air-to-air engagements. The Fakel Design Bureau (MKV Fakel), a part of Almaz-Antey Concern, is responsible for the 9M96 missile family.

The 9M96 missile features an active radar homing head backed by target updates provided by the launch unit’s radar system as well as an Inertial Navigation System (INS) for midcourse guidance. Its cold launch consists of the missile being ejected 30 meters above its canister and thereafter the rocket motor ignites. A Thrust Vectoring Control (TVC) system based on gas flow provides an impressive maneuverability over other current anti-aircraft missiles. So far, the two existing missile variants have a maximum range varying from 40 kilometers to 120 kilometers.

The 9M96E missile variant can hit airborne targets at ranges of up to 40 kilometers and flying at 20,000 meters of altitude. Its blast fragmentation warhead weighs 24 kg and utilizes a radiofrequency fuze. Stored in its sealed canister has a service life of 15 years that can be extended. Both 9M96E and 9M96E2 missiles share many components and are similar in terms of weight and dimensions with the 9M96E being equipped with a less powerful rocket engine.

Launch of the “Redut” SAM missile during tests from Corvette “Sobystvitelny” Project 20380 – via

The SAM is equipped with a directed explosion warhead to improve the chances of fully destroying fast moving and agile targets upon direct impact. The hit probability is 0.9 against aircraft, 0.8 against drones, and 0.7 against missiles. Thrust vectoring makes it possible to achieve high Gs and angular rate capability.

A datalink from the MFMTR X-band radar blast is used for midcourse guidance. Its 24 kg. fragmentation warhead produces a controlled pattern. A radar fuse controls the warhead’s timing.

The 9M96 missile was initially developed for the S-400 Triumf ground-based air-defense system that has already been delivered to China. It will soon be sent to Turkey. India, Saudi Arabia, and Qatar are also quite interested in this system.

The three vertical-launched, solid-fuel, one-stage missiles have a variable range of 1-150 km. at an altitude of 5 m. to 30 km. At a speed of 2,100 m/s they can hit targets traveling at 1000 m/s. A Poliment-Redut-equipped frigate can carry 32 medium/long-range or 128 short-range missiles. Any combination is possible — one launcher can house either one medium- or long-range weapon or four short-range SAMs. The four-faced phased array antenna can track 16 targets at once. The detection range is 200 km. Russian sources report that the system can engage surface targets as well.

The combination of various-range missiles makes it possible for one Poliment-Redut to carry out the missions of three air-defense systems. It provides multi-tier defense, reducing reaction time. It can fire at a rate of one launch per second. The vertical start is an important advantage, enabling the system to counter a target approaching from any direction. These highly agile missiles can use an optimal trajectory to kill highly maneuverable threats. Source

  • launching of anti-torpedoes and small-size heat-seeking torpedoes.



Anti-torpedoes of the Paket-E/NK system are positioned under water with a program set by the ship’s onboard equipment, and when approaching the target torpedo they are guided by the acoustic active/passive homing system. An anti-torpedo is capable to gain the speed of up to 50 kph and carry a warhead yielding up to 80 kg in TNT equivalent. Source

MTT small-size thermal torpedo



The MTT is fired from a common transport-launch canister mounted on board a surface ship or from a submarine torpedo tube.


This torpedo incorporates:

  • a new more powerful piston engine operating on a pronit-type high-energy single-component fuel, which gives the torpedo a capability to kill high-speed nuclear-powered submarines;
  • a new homing system with digital signal processing;
  • on-board computer;
  • directional explosive charge.

The torpedo can simultaneously track several targets, including in a sonar countermeasure environment, and can be used in a wide envelope of depths, including shallow waters.

The MTT has modular design, allowing the replacement of its component parts. Compatibility of its onboard systems with the platform’s battle management systems is achieved by programming its system unit during adaptation to the given ship project. Source

Propulsion details

The Gremyashchy-class corvette is powered by two 1DDA 12000 marine diesel-diesel units, each consisting of two 16D49 diesel engines and reverse gear block. Developed by PJSC Kolomensky Zavod, the DDA-12000 unit generates an output power of 12,000hp.

The vessel is further fitted with two five-blade fixed-pitch propellers driven by the diesel engines through two shafts.

Sequential turbocharging system permits to shut off one of the turbochargers at low and average loads thus increasing torque at crankshaft flange at ship speeding up and maneuvering.

DDA can run with engine combined or separate operation by transmitting power from one (either of the 2 engines) or 2 engines simultaneously to the propeller via gearbox. DDA includes highly efficient diesel engines by Kolomensky Zavod equipped with sequential turbocharging system, improved hydraulic performance, strengthened block elements and parts of sleeve assembly.





Gremyashchy-class multi-purpose corvettes performance

The Gremyashchy-class corvettes have a speed of 27kt and a cruising range of 3,500mi. They are capable of performing missions for up to 15 days.

The ship’s bulbous bow offers increased speed and fuel efficiency by reducing the drag.
