Hamina Class, Finland

The Hamina Class fast attack craft were built by Aker Finnyards in Rauma, Finland for the Finnish Navy. Previously known as Rauma 2000, fast attack craft regularly patrol the Finnish coastline. Four vessels home-ported at Upinniemi are operated under Squadron 2000.



The Hamina Class fast attack craft is capable of conducting patrolling and combat missions as a missile boat. The lead vessel in class, FNS Hamina  was ordered in December 1996 and commissioned in August 1998. The order for the second craft, FNS Tornio, was placed in February 2001. It was commissioned in May 2003. The third, FNS Hanko was ordered in December 2003 and commissioned in June 2005. The final ship in the class, FNS Pori, was ordered in February 2005 and commissioned in June 2006.

The Hamina has an overall length of 51m, a waterline length of 44.3m, a breadth of 8.3m and a design draft of 1.7m. Displacement of the ship is 250t and the vessel’s full complement is 23.



Hamina Class design and features



Designed specifically as a stealth ship, the Hamina Class features a round bilge aluminium mono-hull, with a superstructure made of reinforced carbon fibre composite. The shape and materials used reduce the ship’s magnetic, heat and radar signatures. Radar absorbent materials such as kevlar and balsa cover the ship’s metal structures, while its composite parts are made from radar absorbent material.



The low displacement of the Hamina enhances its manoeuvrability. These ships are equipped with water jets instead of propellers, so they operate easily in shallow waters and unconventional waterways. The Hamina Class vessels feature many surveillance and combat capabilities usually found on much larger ships.

The Hamina has the facility to exhaust gases under water, thus reducing thermal signature, or into the air which minimises sound pick-up by submarines. There are 50 nozzles fitted around the decks and upper structures that can spray seawater to cool the vessel, and clean it in case of chemical attack or radioactive fall-out. The life saving equipment includes four inflatable life rafts and one inflatable rescue boat.

The Hamina Class fast attack craft is equipped with TACTICOS (tactical information and command system) combat data system developed by Thales Nederland (formerly Signaal). The centralised combat management system is based on commercial-off-the-shelf (COTS) designs. The system integrates all sub-systems for improving the capability of the craft to simultaneously engage and defeat various types of threats.

Anti-ship missiles

The latest weapon systems are integrated with the state-of-the-art command system. The vessel is armed with four RBS-15 mk3 anti-ship missiles each with a range of over 100km. The onboard Umkhonto-IR surface-to-air missile system can simultaneously engage up to eight aircraft within a 14km range. There is a Bofors 57mm gun installed for surface and aerial targets and two 12.7mm heavy machine guns are also fitted on the craft. The ship can also be fitted with mine rail to detect sea mines.

Bofors 57mm gun



BAE Systems’ 57mm Mk110 (internationally known as the Bofors’ 57Mk3) provides high survivability and tactical freedom at all levels of conflict.

In the littoral scenario the gun must have the capability to engage threats that were impossible to engage with conventional gun systems.

Survivability in such an environment requires an extremely flexible weapon system.


The 57mm Mk110 has this flexibility, which is proven by the fact that it is the deck gun of choice for the US Coast Guard’s National Security Cutter and offshore patrol cutter classes of ships, as well as for the US Navy’s LCS ships. Source baesystems.com

Modern ships must be able to operate in different levels of conflict; from peacekeeping operations firing warning shots to law enforcement missions against pirates, smugglers and terrorists. In military combat, the gun is a vital part of a ship’s self-defense against hostile surface vessels, attack aircraft, anti-ship missiles and shore targets. In the littoral scenario, the gun must be able to engage threats that are impossible to address with conventional gun systems.


Survivability in such an environment requires an extremely flexible weapon system. The low weight and compact Bofors 40 Mk4 gun system with its high rate of fire and ability to switch between optimized ammunition types – including the intelligent 40mm 3P all-target ammunition – provides high survivability and tactical freedom at all levels of conflict. Source: baesystems.com

RBS-15 mk3 anti-ship missiles


The RBS15 Mk3 surface-to-surface missile (SSM) was developed jointly by Diehl BGT Defence and Saab Bofors Dynamics. It is the latest variant of the RBS15 anti-ship missile family. The RBS15 Mk3 is in service or on order with Sweden, Germany, Poland and Finland.

Developed as an upgrade of combat proven RBS15 Mk2 missile, the Mk3 was successfully test fired at an FMV (the Swedish Defence Materiel Administration) test range in October 2008. The first missile was assembled outside Sweden in Germany in December that year.

The RBS15 Mk3 is a fire-and-forget, subsonic cruise type missile launched from ships and trucks. The missile can be used for anti-ship missions and land strikes.


The forward part of the RBS15 Mk3 missile includes guidance and electronics section followed by warhead and fuel section. The rearward section consists of wings and turbojet engine and two parallel booster motors. The missile has cruciform wings that can be retracted during storage.

The missile has a length of 4.35m, fuselage diameter of 0.5m and a wing span of 1.4m. The launch and in-flight weights of the missile are 800kg and 650kg respectively. The RBS15 Mk3 can strike targets within the range of 200km, while travelling at a subsonic speed of 0.9Mach.

The missile can be equipped with an optimised heavy HE blast-fragmentation warhead. The highly efficient warhead can penetrate into the hull of any modern vessel.

TR 60-5 variable-thrust turbo-jet engine

The ship and truck-launched RBS15 Mk3 variants are launched by two booster motors. The missile is powered by TR 60-5 variable-thrust turbo-jet engine developed by Microturbo (a Safran Group company and subsidiary of Turbomeca). The TR60-5 engine incorporating a 3-stage-axial compressor delivers a thrust of 350 to 440daN. Source naval-technology.com

Umkhonto-IR surface-to-air missile system



Umkhonto (Spear) Missile is an indigenous product, designed, development and manufactured in South Africa. The design of Umkhonto was inspired by the Zulu military commander King Shaka who introduced to his warriors amongst other things, the short Spear, the cow horn formation and the element of surprise. Similarly the Umkhonto missile design includes Stealth (passive IR seeker and low smoke rocket motor) and flexibility (multi target engagement and ability to launch from any position).

The Umkhonto vertical launch Surface to Air Missile (SAM) was developed for the SA Navys Meko A200 class frigates, and has been in service since 2001. Other Navies have also acquired the Umkhonto system, this include amongst others the Finnish Navy. The missile is high-velocity and infrared homing, providing all-round defence against simultaneous attacks from missiles and aircrafts. Although, this is a surface to air missile, it is also capable of taking out stationery surface targets. The Umkhonto was designed with a 23 kg warhead for High-kill probability, unlike other SAM missile systems in its class.

Torpedo 47


Torpedo 47 is Sweden’s new lightweight torpedo system for defense against foreign submarines. FMV has contracted Saab AB to develop, produce and integrate the system. The cooperation also includes FOI (the Swedish Defence Research Agency) and the Swedish Armed Forces (SwAF).


There are major challenges in locating and attacking foreign submarines in the Baltic Sea. The factors that contribute to the difficulties are the shallow waters of the Baltic Sea, with a topography and a bottom that challenges the sonar systems. The brackish water, the complexities of the archipelago and the intensive sea traffic are further aggravating factors.

These factors set tough requirements on the torpedo’s ability to:

  • Localize and identify submarines
  • Navigate under water
  • Communicate with the firing platform

The sensor system that will localize and identify submarines is tailor made for the environment in the Baltic Sea. Depending on the local environment the torpedo must have the ability to alter speed, navigate with high accuracy and communicate efficiently with the firing platform.

The new torpedo system is primarily intended for the Swedish submarines and Visby-class corvettes. The system in also prepared for helicopter integration. Source: fmv.se

Sensors and radar equipment


FNS Tornio

The ship is equipped with TRS-3D multimode acquisition radar, Raytheon ARPA navigation radar and Signal Scout I-band surface search radar. The sonar suite includes a Simrad Subsea Toadfish active high-frequency search and attack sonar, and a Sonac/PTA towed array sonar.

TRS-3D multimode acquisition radar


Depending on the activated radar mode, the detection range of the radar covers up to 200 km and the corresponding update times between 1 and 6 seconds.TRS-3D/16-ES is a fully coherent multi-mode phased array C-band radar capable of fully automatic detection, track initiation, and classification of various types of targets. Even under severe clutter conditions encountered in the littoral, it detects and tracks with a particular emphasis on small, fast and low-flying aircraft, missiles, hovering helicopters and asymmetric threats. This ensures minimal operator workload and maximises operational effectiveness.


TRS-3D/16-ES supports the full operational capabilities of several self-defence missile systems, and can serve as a stand-alone radar for the surveillance and self-defence requirements of single-radar ships operating in littoral waters, or as the self-defence radar on large frigates and multi-radar ships.

For weapon support and target assignment, TRS-3D/16-ES supplies reliable target data instantaneously. It features the high tracking accuracy to permit deployment of different types of missiles against aircraft and anti-ship missiles. Thanks to the accuracy of the gun-fire support mode, a dedicated fire control system for surface targets is not required.

TRS-3D/16-ES operating in NATO G-Band is the best compromise for long-range detection performance, short reaction times, and the required accuracy for cueing weapon systems and dedicated fire control sensors.

The lightweight primary antenna is fitted with an integrated Mode 5/S-capable IFF antenna.

TRS-3D/16-ES is able to correlate the primary and secondary radar plots/ tracks within its own radar tracker to provide even higher quality data to the combat management system.

CEROS 200 radar and optronic tracking fire control director


Wikimedia Commons

Saab’s CEROS (Celsius Tech Radar and Optronic Site) 200 is a ship-based search and tracking radar system capable of engaging targets above supersonic speeds. The CEROS employs a variety of sensors such as infrared, electrooptical, televisual, and laser. According to a publication by Saab, CEROS is able to detect sea-skimming missiles via its patented CHASE algorithm. Saab explains that this algorithm mitigates the effect of multiparty wave interference, which is when signals are sent to a receiver by multiple sources. For example, a missile may emit a signal to a receiver, which then sends it to command and control at the same time that a signal directly from the missile reaches command and control. In this instant, the two signals would arrive with different phase shifts — think: a sine wave placed in front of another, so that there’s no exact overlap. This can result in the ghosting effect sometimes observed on television in which images appear to have a shadow duplicate on them. Source missiledefenseadvocacy.org

The Rheinmetall MASS (multi-ammunition soft-kill system) can protect the craft from sensor-guided missiles by launching Philax chaff and infrared flare decoys.

Superior protection with MASS

Guided missiles and other projectiles pose a constant threat to civilian shipping and naval vessels alike. MASS protects ships from attacks using advanced, sensor-guided missiles on the high seas and coastal waters as well as from asymmetric, terrorist-type threats. MASS fires decoy rounds which lure incoming projectiles away from their intended target.

Fully automatic, the MASS naval countermeasure system offers significant tactical, operational and logistical advantages and can be installed onboard any vessel. Moreover, it can be integrated into any command and control system or operated in standalone mode.

The MASS system’s innovative, programmable omnispectral rounds assure protection in all relevant wavelengths of the electromagnetic spectrum (radar, infrared, laser, EO, UV). Numerous international test campaigns have demonstrated its effectiveness in compelling fashion.

MASS with integrated detection unit

Featuring an integrated detection unit, the “MASS ISS – Integrated Sensor Suite” represents an innovative departure in naval electronic warfare. Jointly developed by Rheinmetall Defence and Saab (Electronic Defence Systems), this new version of MASS comes with sensors capable of detecting both radar and laser threats. Source spacewar.com

Russia freezes Iran missile sale following Israeli pressure

According to Arutz Sheva

Following protests by Israel, Russia freezes controversial sale of heavy anti-air missiles to Iran

By David Rosenberg First Publish: 3/6/2016, 7:46 AM

Russian President Vladimir Putin has frozen missiles bound for Iran amid Israeli protest of the sale, the Kuwaiti paper Al-Jarida reports.

According to the report, an order of S-300 heavy surface-to-air missiles purchased by Iran has been put on hold by the Russian leader following talks with Israeli officials.

Israel criticized the sale, claiming that at least some of the S-300 missiles would likely fall into the hands of the Hezbollah terror group in Lebanon. The presence of long-range anti-aircraft missiles along Israel’s border would threaten both military and civilian flights inside Israel.

According to Al-Jarida, Russia halted the shipment of the missiles after Israel provided evidence that other surface-to-air missiles sold by Russia to Iran had ended up in Hezbollah’s hands.

Russian pilots operating in the area confirmed Israel’s claims, positively identifying SA-22 missile batteries in Hezbollah-controlled territory in Lebanon.

Since the outbreak of the Syrian civil war, military ties between Russia, Syria, and Iran have tightened, with increased sales of advanced weapons and even direct intervention by Russian forces in the area.

With the release of billions of dollars in frozen assets and the end of economic sanctions, Iran has placed large orders for Russian-made heavy weaponry, including missiles, warplanes, submarines, and tanks.

However, Israel’s own ties with Moscow have similarly strengthened, with Russia granting the Israel Air Force freedom to operate over Syria against threats to the Jewish state, while Israel has, among other things, granted Russian aircraft permission to use Israeli air space in their battle against Islamist rebels.
