F125 Baden-Württemberg Class Frigate, Germany

The German Navy’s new F125 frigate will have the capability to be deployed worldwide for up to two years before returning to the home base and can be in operation for up to 5,000h a year, including under tropical conditions. F125 is the project name for the Type 125 Baden-Württemberg class of frigates.

The main mission of the F125 frigate is taking part in joint assignments, including multinational assignments in network-centric operations. The 5,500t displacement frigate has a new and stealthy design of hull and superstructure, which appears to be based on a highly modified Meko-D configuration.

The concept of the replacement frigates was originally as a multi-role combatant but by 2005, the requirement for the F125 was based on a capability to counter asymmetric threats and perform stabilisation operations with lethal and non-lethal intervention. The German Navy announced that the F125 would be armed with land attack systems and air warfare point-defence equipment but would not be equipped with sonar.

“Each F125 frigate has two crews of typically 105 to 120 people, which are changed every four months.”

In June 2007, ThyssenKrupp announced the Arge F125 consortium had been contracted by the German Federal Office for Defence Technology and Procurement (BWB) for four F125 frigates. The Arge F125 consortium comprises the industrial leader, ThyssenKrupp Marine Systems (including Blohm + Voss and Nordseewerke) with Lurssen Werft.

Construction began in May 2011 and the first frigate, Baden-Württemberg, was christened at ThyssenKrupp Marine Systems’ Hamburg site in December 2013. Christening of the second frigate, Nordrhein-Westfalen, took place in April 2015 and keel for the third frigate, Sachsen-Anhalt, was laid at the Hamburg site in June 2014. The keel laying ceremony of the final 125-class frigate, Rheinland-Pfalz, was held in January 2015.

Germany’s new frigates are overweight and float with a persistent list to starboard: Here

Excerpt

Germany’s much-delayed new frigates, built by ThyssenKrupp (TKAG.DE) and Luerssen for at least 650 million euros (£551.4 million) apiece, are overweight and float with a persistent list to starboard, according to a confidential report seen by Reuters.

The ships, designed to need a crew of only 120, less than half their predecessors, are a crucial element in Germany’s plans to beef up its military to face an increasingly uncertain European security landscape and a more assertive Russia.

Designed to remain at sea for far longer than the German armed forces’ existing fleet, the new F125 frigates need extensive servicing only once every two years, compared to once every nine months for their predecessors.

German Navy’s Third F125 Frigate Christened: Here

Excerpt

The new F125-class frigates replace the German Navy’s eight Bremen-class frigates. The first two frigates of the four vessel series, Baden-Württemberg and Nordrhein-Westfalen, were christened in December 2013 and April 2015, respectively.

Sachsen-Anhalt is scheduled to be handed over to the German defense procurement agency BAAINBw in early 2019. Commissioning and in-port trials of the first F125 frigate, the Baden-Württemberg, have now advanced to the stage where sea trials can commence as planned in spring this year. Handover of the Baden-Württemberg to the BAAINBw is scheduled for mid-2017. The contract for the F125 program is worth around two billion euros in total.

Each frigate has two crews ranging between 105 and 120 people, who are changed every four months. The number of crew represents an approximately 50% reduction in crew compared with previous generation frigates and is achieved partly through a high level of automation.

The frigate also accommodates 50 special forces soldiers and their equipment. The necessary transport can be two helicopters or four armed boats.

Command and control

ELEC_Atlas_Naval_Combat_System_lg

In March 2006, EADS was contracted to supply the F125 command and control and weapons deployment system, FuWES (Fuhrungs-und Waffeneinsatzsystem). The contract covered the development and delivery of the system, including the complete software, hardware and infrastructure, and the FuWES testing and performance verification for all four frigates.

cms

The FuWES system has an open and modular structure allowing flexibility to accommodate future additional or modified systems. In order to provide tactical data exchange and a high level of interoperability with other joint and combined military platforms, the communications systems, link 11, link 16 and link 22 are integrated into the F125 command and control system. The combat management system is operated from the Atlas Elektronik OMADA consoles, designed specifically for the F125.

The upcoming Oto-Melara (now OtoBreda) 127/64 Lightweight (LW) naval gun is a rapid fire gun mount suitable for installation on large and medium size ships, intended for surface fire and naval gunfire support as main role and anti-aircraft fire as secondary role. The compactness of the gun feeding system makes possible the installation on narrow section crafts.

The gun can fire all standard 5 inch (127mm) ammunition including the new Vulcano long range guided ammunition.

Modular automatic feeding magazines allow the firing of up to four different and immediately selectable types of ammunition; the magazines (four drums, each with one shell ready to fire) can be reloaded while the mount is in operation.

An ammunition manipulator system is available to transport projectiles and propelling charges from the main ammunition store to the feeding magazines, which are automatically reloaded. Ammunition flow is reversible. Rounds can be automatically unloaded from the gun. Digital and Analog interfaces are available for any Combat Management System, also according to Corba protocol. The 127/64 LW Naval Gun Mounts includes a Vulcano module, which acts twofold:

– Programmer for ammunition’s fuse and guidance system.
– Mission Planning and Execution for Naval Fire Support Action (firing solutions, selection of ammunition, definition of trajectories and firing sequences, ballistic computations accounting for ammunition type, etc.), as a standalone or in interaction with ship’s Network Centric System.

12.7 mm Hitrole-NT remote-controlled machine gun turrets

HITROLE® 12.7mm naval turret is a modern system fully controlled from a remote station via an advanced control console that allows the gunner to operate from a protected position within the ship’s structure: any operation, including loading and recocking, can be undertaken with maximum safety for the operator. 

Low weight and high level of flexibility make this turret particularly suitable for installation as main armament of any small patrol vessel engaged in border control, maritime traffic interdiction or as a secondary armament on larger ships for self protection in the anti-terrorism role.
The turret is electrically operated and very accurate due to powerful digital servos.

Sighting and tracking actions are performed by means of a high performance day TV camera.
Ballistic Routine is available to provide aid while engaging moving targets.
Additional options include IR sensor for night operation as well as a Laser Range Finder, an Auto Tracker and the sensor suite is protected within a watertight shelter.

HITROLE® 12.7mm turret is a stand alone system with stabilization achieved via built-in Gyros system: no external signal is required by the turret from other ship systems.
Upon request, the HITROLE® 12.7mm turret can also be linked to other Electro-Optical sensors on board the ship and functional interface to ship’s Combat Management System can also be provided. 

For special operations the 12,7mm (0.50 cal.) machine gun can be replaced with a 40mm Automatic Grenade Launcher (40mm AGL), capable of shooting also ‘non lethal ammunition’. The weapon replacement can be achieved in a few minutes with no need of special tools.
Belted rounds are available for both the 12,7mm( 0.50 cal) machine gun and the 40mm AGL in standard ammunition boxes, (130 rounds for the 12,7mm (0.50 cal) machine gun and 32 rounds for the 40mm AGL).

An optional ammunition loading system can be installed in a dedicated support in order to increase the available 12,7mm (0.50 cal) rounds up to 400.

SAAB RBS15 MK3 anti-ship missions and land strikes

Korvet GÄVLE skjuter en Rb15M MKII under en förtroendeskjutning hösten 2008

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.

Variations of RBS15 Mk3 missile

Image: defencetalk.com

The RBS15 Mk3 is available in three versions – ship-launched, truck-launched and air-launched. The ship-launched variant can be installed on small and large sized warships such as fast patrol boats, frigates and corvettes. The missile is easily integrated with the combat management system and can be operated as stand-alone or fully integrated architecture.

The air-to-ship launched version is suitable for modern fighter aircraft. The rapidly deployed truck-launched missile battery provides coastal defence against hostile forces. The highly mobile launch platforms allow the launch of the missile from hidden positions located far away from the coast.

RBS15 Mk3 design and features

Image: defenceindustrydaily.co

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.

RBS15 Mk3 guidance system

The RBS15 guidance and control system includes an inertial navigation system and a GPS receiver, a radar altimeter and a Ku-band radar target seeker. The RBS15 missiles are resistant of enemy countermeasures. Two or more missiles can be programmed to hit the target simultaneously from various directions to better penetrate the air defences of warships.

The missile features low radar cross section and IR signature. It has sophisticated target discrimination and selection capabilities. It is extremely resistant to chaff, active jammers, decoys and other electronic countermeasures (ECM).

The RBS15 Mk3 is a low sea-skimming missile performing unpredictable evasive manoeuvres. The missile increases its thrust in the terminal phase to defeat missiles, guns and close-in weapon systems (CIWS). The missile engagement planning system (MEPS) provides advanced user interface for generating plans for different scenarios.

Warhead and propulsion of RBS15 Mk3 SSM

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.

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.

German Navy K130 Corvettes Ready for Saab RBS-15 Mk3 Anti-Ship Missiles: Here

The German Navy has authorized on 3 June 2016 the use of the surface-to-surface Saab RBS-15 Mk3 missiles aboard the K130-class corvettes. This type of missiles will give the Marine the capability to engage land targets from the sea.German Navy Braunschweig class corvettes (K130)

The F125 has two 21-cell MK49 launchers armed with the Raytheon RIM-116 rolling airframe missile (RAM). The RAM point defence missile is a lightweight, infrared-homing, surface-to-air missile for deployment against incoming anti-ship cruise missiles. The forward launcher is installed immediately forward of the bridge and the aft launcher is installed on the roof of the helicopter hangar just forward of the helicopter deck.

The Rolling Airframe Missiles, together with the Mk 49 Guided Missile Launching System (GMLS) and support equipment, comprise the RAM Mk 31 Guided Missile Weapon System (GMWS). The Mk-144 Guided Missile Launcher (GML) unit weighs 5,777 kilograms (12,736 lb 2 oz) and stores 21 missiles. The original weapon cannot employ its own sensors prior to firing so it must be integrated with a ship’s combat system, which directs the launcher at targets. Source seaforces.org

Raytheon RIM-116 rolling airframe missile (RAM)

image_popup

RAM Block 2, the latest step in the development of the Rolling Airframe Missile, is a kinematic and Radio Frequency (RF) receiver upgrade of Block 1/1A. A larger, more powerful, composite case rocket motor and advanced Control Section (4 canards vs. current 2) make the missile two and a half times more maneuverable with one and a half times the effective intercept range. This provides the Block 2 missile with the capability to defeat high-maneuvering threats, increasing the survivability of the defended ship. An enhanced RF receiver allows detection of anti-ship missiles that employ low probability of intercept receivers.

The Mk-44 Guided Missile Round Pack (GMRP) and the Mk-49 Guided Missile Launching System (GMLS), which hold 21 missiles, comprise the Mk-31 Guided Missile Weapon System (GMWS). The system is designed for flexibility in ships’ integration, with no dedicated sensors required. A variety of existing ship sensors can readily provide the target and pointing information required to engage the anti-ship threat.

The Mk-44 GMRP is also the missile used in the SeaRAM Anti-Ship Missile Defense System, replacing the M601A1 Gatling gun in the Phalanx Close-In Weapon System (CIWS) with an 11-round launcher. The Phalanx sensor suite serves as the search and track radar designating the threat for RAM missiles to intercept.

The frigates have no conventional on-board sonar but instead have a diver and swimmer detection sonar to counter terrorist threats. The frigates are equipped with a 360° infrared surveillance system installed on the front surface of the tower mast at a position just lower than the air and surface search radar.

Radar systems will include an EADS TRS-3D air and surface search radar, navigation and fire control radars. The TRS-3D radar carries out automatic detection, track initiation and tracking of all types of air and sea targets. *Note it is TRS-4D*

The navigation radar is installed on the roof of the bridge.

TRS-4D naval radar

TRS-4D-naval-radar

TRS-4D enables ships ranging from patrol vessels to frigates to carry out the various detection tasks required of ship-borne, medium-range radar systems both in the open sea as well as in complex coastal zones with a high target density. Compared to conventional radars, this more accurate, faster system now tackles a wider-than-ever scope of targets, e.g. for protection against asymmetric attacks.

The new radar is based on a unique system concept. In contrast to any other systems available on the market, the TRS-4D is the first surveillance radar to make full use of the advantages of AESA technology (AESA = Active Electronically Scanned Array), which is based on multiple independent emitters. This results in a detection performance that is unprecedented worldwide.

For the F125 frigates the system will be deployed in a version with four fixed arrays. Source: Defense Talk

The F125 class has the non-rotating multi-function Airbus Group TRS-4D/NR (Non Rotating) Active Electronically Scanned Array (AESA) C-band radar version with two fixed arrays on the forward radar mast and two on the rear mast. The radar works using the technology of electronic beam scanning (E-Scan), which is deployed for both conventional, mechanically rotating aerials and immovably mounted radar aerial panels. Four aerial panels are distributed between two ship’s masts, each carrying two panels. Due to the real-time electronic control of the beam, this radar can carry out several reconnaissance tasks at the same time. For example, it can do a long-range scan of the sea and airspace while simultaneously concentrating on tracking individual targets. In comparison to conventional radars it thus achieves a significantly higher surveillance and detection efficiency and reliability. The radar’s performance is essentially based on numerous transmitter and receiver modules in the aerial, which are made from materials especially suitable for high frequencies. The radar offers three fundamental modes: Surveillance, Self-Defense and Sector (see table for performances). The maximum range of the radar is up to 250km, up to 14km for small surface targets and up to 100km for maritime patrol aircrafts. It can track up to 1,000 targets.

MSP 600 – Optronic Modular Sensor Platform

msp500_signim_bg-jpga782f1ca-1707-4879-8603-688e68cb2e10original

The Modular Sensor Platform MSP 600 is a light-weight four axis stabilized electro-optical system, which can be used in land-based applications (e.g. border or coastal surveillance and air defence), airborne (e.g. helicopters) and shipborne as a stand-alone sensor or as part of a command and fire control system. Always operating in passive mode, the MSP 600 is virtually undetectable and thus complements, or is a substitute for, radar.

The MSP 600 comprises a thermal imager, a daylight camera, a laser range finder and a dual mode tracker. To achieve excellent stabilization values of the line of sight, the sensor package is controlled by a coarse/fine system and is thus independent of environmental influences. The MSP is an excellent data source for tactical and/or nautical navigation as well as for fire control. Source rheinmetall-defence.com

 SIMONE (Ship Infrared Monitoring Observation and Navigation Equipment)

simone_2_01

In order to close the capability gap in autonomous close-in monitoring and to increase protection against asymmetric threats, Diehl BGT Defence was tasked with the development of an optical surveillance system. Diehl designed SIMONE (Ship Infrared Monitoring Observation and Navigation Equipment) to equip the new German frigates. The system  provides complete and permanent monitoring of the vessel´s structure as well as it allows early and reliable detection of small objects, even very small suspicious objects such as inflatable rubber boats or persons swimming, enabling flexible and precise response. SIMONE takes into account the new crew concept envisaging less manpower by provision of autonomous monitoring requiring no additional personnel. Automatic alarm with relevant data for the command and control system is generated in case of detected threats. Uncooled infrared detectors featuring longevity as well as 24/7 high image quality meet the requirement of permanent operational readiness. Source navalanalyses.blogspot.com

SIMONE consists of a sensor suite either fully integrated into the ship (in case of new constructions) or retrofitted into existing platforms. Figure 1 shows an overview of the system architecture. Modules containing uncooled IR microbolometer sensors are arranged on the ship to continuously cover its surrounding. Using this configuration, the number of ‘dead zones’ caused by shadowing are minimized, and observation is possible from the ship’s hull. Image data is transferred to a central processing cabinet (a computer) for real-time processing over Ethernet. Live video imagery and alarm data can be fed to several clients (computers that possess a network connection to the processing cabinet) simultaneously. All of the system components are connected by fiber-optic links.

004166_10_fig1Figure 1. System architecture for automatic surveillance of a ship’s surroundings using sensors.

The homogeneous and simultaneous delivery of the imagery visualization is executed by the human machine interface. This characteristic is particularly important for scenes covering a wide range of temperatures and containing objects with little radiometric contrast compared to their background. Automatic image processing is performed on the full pixel depth. However, the interpretation of the scene content by human operators requires the contrast of the imagery to be improved because the human eye is limited in terms of the range of contrast distinguishable. To improve the contrast, we use a range of algorithms to process the imagery. Figure 2 shows the result of employing these algorithms to enhance the human operator’s ability to capture the full visual content of the image. The top-left image is the raw data. Simple adjustments to brightness and contrast highlight details of the area marked by the red rectangle, whereas information outside this area is lost. Image enhancement algorithms automatically perform a local adjustment of brightness and contrast based on the image content. The result is the detailed image on the bottom right.

By distributing the sensors on the ship, we aim to create a panoramic view of the surroundings, which can be displayed on the human machine interface together with alarm data (see Figure 3). Indeed, our system has been qualified according to military standards for use in harsh naval environments, including electromagnetic compatibility. Source spie.org

Countermeasures

Much of the electronic warfare suite has not been announced but it will include four Rheinmetall multi-ammunition softkill systems (MASS). The MASS decoy and mini mortar dispensers are installed on the port and starboard sides above the bridge and on the helicopter hangar roof.

The automatic decoy system MASS provides a unique level of protection against modern sensor-guided missiles. MASS can be installed on ships of all types and can be integrated into existing command systems. The new MASS_ISS features built-in sensors for detecting radar and laser threats. Programmable and omni-spectral, the system’s innovative ammunition provides protection in all relevant wavelengths of the electromagnetic spectrum. Source rheinmetall-defence.com

Propulsion

23mlvmcImage: Thyssen Krupp

The frigates are fitted with a new combined diesel electric and gas (CODLAG) electrical propulsion system with a 20MW General Electric LM 2500 gas turbine, four MTU 20V 4000 M53B diesel engines providing 3,015kW each (total 12.06MW) and two Siemens electric motors providing 4.5MW each (total 9MW).

1 x General Electric LM2500

34155-9655357

The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine.

The LM2500 is available in 3 different versions:

  • The LM2500 delivers 33,600 shaft horsepower (shp) (25,060 kW) with a thermal efficiency of 37 percent at ISO conditions. When coupled with an electric generator, it delivers 24 MW of electricity at 60 Hz with a thermal efficiency of 36 percent at ISO conditions.
  • The improved, 3rd generation, LM2500+ version of the turbine delivers 40,500 shp (30,200 kW) with a thermal efficiency of 39 percent at ISO conditions. When coupled with an electric generator, it delivers 29 MW of electricity at 60 Hz with a thermal efficiency of 38 percent at ISO conditions.
  • The latest, 4th generation, LM2500+G4 version was introduced in November 2005 and delivers 47,370 shp (35,320 kW) with a thermal efficiency of 39.3 percent at ISO conditions.

LM2500 installations place the engine inside a metal container for sound and heat isolation from the rest of the machinery spaces. This container is very near the size of a standard 40-foot (12 m) intermodal shipping container – but not the same, the engine size very slightly exceeds those dimensions. The air intake ducting may be designed and shaped appropriately for easy removal of the LM2500 from their ships. Source wikiwand.com

    That’s why If Thailand or the Philippines want a Cold war era Frigate, they should talk to Germany ASAP on the Bremen class frigates. The Bremen class frigates were designed for AAW and ASUW warfare.
