3M54E Sizzler supersonic ASCM

The more advanced 3M-54E combines the subsonic cruise airframe of the 3M-54E1/3M-14E with a Mach 2.9 rocket propelled guided payload. It also employs the ARGS-54E seeker.

Like its subsonic sibling, it approaches from under the radar horizon using the same radar seeker to detect its target. Once locked on, it discards the cruise airframe, fires its rocket motor, and accelerates to Mach 2.9 at a sea skimming altitude of 15 feet. Novator claim the missile follows a zig-zag flightpath to defeat defences. Both the 3M-54E1 and 3M-54E are small weapons which are difficult to detect on radar, especially should even basic radar signature reduction techniques be applied to them.


Zvezda Kh-35 Uran (SS-N-25 Switchblade) Uran-E shipborne missile system equipped with KH-35E anti-ship missiles

The Uran missile systems comprise 16 Kh-35 missiles – 4×4 launchers with pressurised transport-launching containers. The Uran system now serves as armament of Project 1149.8 missile equipped gun boats and other vessels. A coastal defense variant and, more recently, an antiaircraft variant were later developed on the basis of this missile.The Kh-35 missile has a normal aerodynamic design and an aluminium-alloy airframe. The missile’s power plant consists of a solid-fuel booster and a turbojet powerplant. The missile’s take-off weight is 750 kilograms, the warhead weighs 150 kilograms with a range of up to 130 kilometres.

The Kh-35U anti-ship aircraft missile (Article 78U), propelled by a turbojet engine, flies toward its target at a speed of about the 300 m/s at an extremely low altitude. Owing to its high-precision radio-altimeter, the missile can skim the sea waves at an altitude of 3-5 metres at the terminal phase of trajectory. Its guidance system combines inertial guidance for during the initial flight stage and active-radar guidance during the remaining flight stage.

The missile has a folding wing and a folding tail fin.For use by coastal or shipborne launchers the missile is equipped with a rocket starter-accelerator, a container-type launcher having room for four missiles.

100-mm А190- 01 Lightweight Multipurpose Naval gun03.jpgdc8c677a-1b24-42ad-b2dc-176c6e06dd87Original

Burevestnik manufactures two variants of 100-mm А190 Lightweight Multipurpose Naval gun: А190E and А190-01.

100-mm А190 Lightweight Multipurpose Naval Gun is a single-barrel turreted automatic gun that may be installed on ships with the displacement of 500 t and more. Upon the operator’s command the fire control module automatically turns the artillery system to standby or combat-ready position, ensures ammunition selection and feeding, gun laying and firing. As a result, the artillery system has minimum response time and high rate of fire.

Main technical data

Rate of fire, rpm up to 80
Maximum firing range, km over 20
Elevation, degree -15 to +85
Training, degree ±170
Projectile weight, kg 15,6
Number of ready-to-fire rounds 80
Weight, t 15

А190 Naval Gun can fire HE (impact fuze) and AA (time fuze) case ammunitions.
The main advantages of А190 system:
– automatic firing mode with main and back-up control means and the capability to operate in EW battlefield environment;
– minimal dead zones when engaging various target types;
– fast reaction (2…5 sec) to counter air threats. Quick shift of fire when engaging multiple targets.

The upgraded version designated as А190-01 provides significant increase in combat effectiveness. High survivability, reliability and combat effectiveness make it possible to operate the gun in various environments day and night all year around. Data

AK-630M x 1

The gun itself is a 6 barrel Gatling gun designated as AO-18.  The barrels are in a single block, having exhaust-driven joint automatics.  They are belt fed with a flat magazine in the AK-630 and a drum magazine in the AK-630M.  These weapons form a part of a complete self-defense system called A-213-Vympel-A, which includes gun, radar, optical and TV control systems.  A single MP-123 Vympel system can control two 30 mm guns or one 30 mm and one 57 mm gun.  This system can engage air targets at ranges up to 4,000 m (4,400 yards) and surface targets at ranges up to 5,000 m (5,500 yards).  The TV control system can detect MTB sized ships at the distance of 75 km (40 nm) and the fighter-size air targets at 7,000 m (7,600 yards).  This system is completely automatic and does not require human supervision although it can be directed from optical control posts in case of damage or for firing on shore targets.

Palma antiaircraft artillery systems

The Palma is a ship-based air defense system designed to engage rotary- and fixed-wing aircraft, aerial bombs, anti-ship cruise missiles, small displacement vessels and small targets onshore. The weapon system consists of two 30mm six-barrel AO-18KD/6K30GSh automatic cannons and up to eight Sosna-R laser-guided hypersonic surface-to-air missiles (two 3R-99E firing modules). All in, the Palma can engage up to six targets simultaneously at distances between 200 and 8,000 meters and flying at a maximum altitude of 3,500 meters. The weapon system only takes three-to-five seconds to get ready to fire.

The 30mm AO-18KD cannons range varies between 200 and 4,000 meters and flying below 3,000 meters. The ammunition load is 1,500 rounds of armor piercing or high explosive fragmentation and incendiary ammunition. The guns on a 3S-89 mount feature a maximum rate of fire of 10,000 rounds per minute. The Sosna missile system is effective against airborne targets at altitudes between 2 and 3,500 meters and ranges between 1,300 and 8,000 meters. The ECM and jamming-resistant fire control system provided to Palma includes 3V-89 TV and Infrared cameras, laser range-finder, laser beam missile guidance system and 3Ts-99 target acquisition radar.

Air defense 1 x Gibka turret mount, 24 missiles

GHIBKA 3M-47 (3M47 Gibka) Turret Mount

The 3M-47 Ghibka turret was designed by Altair Naval Radio Electronics Scientific Research Institute and is manufactured by the Ratep Joint Stock Company.

Ghibka 3M-47 (3M47 Gibka) Turret Mount is intended for guidance and remote automated launching of IGLA type missiles to provide protection of surface ships with displacement of 200 tons and over against attacks of anti-ship missiles, aircraft and helicopters in close-in area..

The turret mount utilizes information from ship’s radars. The missiles are equipped with homing head with optical tracking (passive) and artifical thermal noise detector. The system is design to resist natural (background) and artificial jamming conditions. The turret mount is equipped with 9M39 and 9M342 anti-aircraft guided missiles.

To date, 3M-47 Ghibka is installed on Project 21630 “Buyan” class corvettes, Project 21631 “Buyan-M” class missile corvettes and will be installed on the future Mistral type LHD for the Russian Navy.

Version 1 with 4 SAM
Version 2 with 8 SAM

Igla-S missile

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 turret is remotely operated and can be steered towards targets detected by the Positiv, Furke or Fregat naval radar systems. Final aiming is achieved at the control module through a TV sighting system. According to constructor specifications, the visual detection range of an aircraft through the control module is 12 to 15 Km.
