S-80 SIMULATOR

The new series of S-80 submarines built by Navantia for the Spanish Navy will be equipped with a state-of-the-art Platform Control System and Steering System allowing the operation of the vessel with a relatively small crew. In order to ensure optimal submarine operation, crews must receive the very best type of training and that is where the simulator comes into play, allowing operating crews to get familiarized with vessel performance and events that may occur during navigation.

T

he Platform Simulator (FABA Systems – Control Systems) developed by Navantia in collaboration with important companies such as AVIO (Italy) and Indra (Spain) is intended to meet the requirements specified by the client, the Spanish Navy. The simulator is now working in Cartagena's Submarine School (ESUBMAR), in a specific building, since 2011. Operating a submarine requires special training thus a part of the preparation with this simulator is compulsory.

The students of Cartagena’s submarine school will train with an exact and natural-sized replica of the control room’s portside. The equipment and parts, including the centralised remote control system and the steering system are identical to that of the submarine so that students can get familiar with them.

The S-80 simulator is a full-scale reproduction of the cabin, the port side, and Command and Control area, with all the consoles and panels which comprise the Platform Control System and the Governing System. It also includes the most important Local Control Panels on the starboard side. The Platform Simulator is comprised of advanced software that in a 1:1 scale cubicle simulates the port side and centerline of the Control Room, including all the panels, consoles and elements comprising the Centralized Remote System of the Platform Control System and Steering System. The starboard is also simulated, including the main Local Control Panels (virtual) used for vessel steer.

The idea is to use the Simulator to train the submarine crews and students in all navigation situations

NAVANTIA’S NEW GENERATION OF SHIP MANAGEMENT SYSTEMS

D

uring the last decade, Western Navies assumed a challenge to improve warships operative capacity by integrating and automating their primary and domestic functions. At the same time, the need for large crews was remarkably reduced by implementing commercial-offthe shelf equipment and the most updated technologies available within the industrial field.

Navantia Systems has developed a new integrated systems for platform control and management (IPMS), provided with an open architecture for the integration of all types of additional subsystems and their specific software so that all of them can operate under the same

operative system. The results are new functionalities, meaning great saving for installation, purchasing, and maintenance costs.

Navantia Systems has a wide experience in the integration of IPMS that can be installed in any type of platform, from patrol vessels to aircraft carriers. The IPMS consist of the following components: Operator Console: It is intended to provide surveillance, alarms warning and commands generation.

Local Substations (LSS): Information gathering, execution of control algorithms and sending commands to the machinery actuators.

Data Transmission Network (DTN): for interconnection of data between consoles and substations, ensuring the information integrity The consoles, LSS and DTN can be configured with any COTS available in the market. They can be suited to the ship´s characteristics.

With the purpose of guaranteeing the system survivability, the IPMS

configuration implies a redundant and distributed architecture (not centralised) with identical functionality for all operator consoles. The IPMS architecture allows assigning the platform control to any combination of operator consoles.

The main target in the development of the IPMS is to make the platform status information available from any turned on console.

The control of one subsystem is assigned to only one console, and just those users with Supervisor category are allowed to modify that assignment. The IPMS provides a high automation level, allowing reduced crews safely sail the ship.

COMPLEX organizes and presents the information in the optimal way to help operators get the knowledge of the platform’s state (propulsion, power plant, auxiliaries and damage control) and make the best decisions.

The main functions are:

6

•

Monitoring and Warning functions: Analog and digital information display, communications and sensors diagnosis, alarm warnings and trend charts.

•

Automatic functions: IPMS can operate under different levels of automation: manual, semiautomatic and automatic.

•

Security functions: These functions are used to provide machinery and equipment automatic Emergency Stop, without the operator´s assistance, under risk operating conditions.

•

Damage Control functions: Including management of incidences related whit fire, flo 8oding, smoke, NBQ alarms, stress and stability calculations, on line Personnel location, Kill cards, etc.

Other IPMS services:

•

Navigation data, e-mail, videoconference, video surveillance, on line help, On Board Training System (OBTS).

•

Predefined Configurations: Set of commands issued with a single action. E.g. Firemain valves, Tightness conditions.

Individual and Summary status is shown.

•

Data Logging functions: IPMS has Data Store Units (DSU) which collects and store continuously Events, Alarms, Analog values, operator actions, etc.

•

Playback: projects historical data on the mimics, 3D scenes and Data Viewers. FAM

RESUS - An Advanced Method of Submarine Safety

A

s spin-off product based on established space thruster technologies Airbus Defence and Space (Airbus DS) has developed RESUS (REscue system for SUbmarineS), a system to ensure rapid surfacing in case of submarine emergency situations.

RESUS provides a strong counter measure to all kinds of submarine emergency situations which are especially dangerous when the craft is submerged. Scenarios for RESUS are for example: - uncontrolled dive of the boat due to the jamming of the hydro planes in a diving position on account of hydraulics systems failure or the effect of depth charges, - failure or unresponsiveness to the on-board manoeuvring system,

- outbreak of fire on board, - water ingress into the pressure hull.

In these and other emergency situations which make it necessary to surface the submarine as quickly as possible RESUS is designed to empty the main ballast tanks (MBTs) of the submarine in all diving depths within a very short time (13-20 sec.), working independently from other on-board systems, including the on-board power supply. By using RESUS underwater accidents are converted into surface accidents.

RESUS consists of a number of gas gene¬ra¬tors and the elec¬tro¬nic components to activate the system as well as to control and test the system integrity (see fig).

In standard configuration the Gas Generators (GGs) are installed in the forward and aft MBTs. The electrical connections to the gas generators are collected together in a Cable Distributor (CD). The electrical multi-wire from the Cable Distributor passes a feed through between the pressure hull and the MBT and is connected to the Control and Test Unit (CTU) located in the submarine control room. Remote Starting Devices (RSDs) are located in several positions along the boat. Thus RESUS can be put into operation immediately.

The number of gas generators needed for rapid surfacing depends on the class of the submarine, the actual diving depth and the volume of the MBTs. The required number of

  10 

gas generators to be used is determined by the Control and Test Unit (CTU) on the basis of the diving depth measured by the Diving Depth Measuring Device (DDMD).

The gas generators produce a hot gas that is cooled and guided by suitable gas ducts to the top of the MBT. This provides enormous buoyancy, stabilising the submarine

FAM Reportaje attitude immediately and raising the boat safely to the surface. The gas generators in the aft MBT stabilise the boat when surfaced. In case of combined failure of the main propulsion engine and water inrush into the submarine pressure hull through a hole with 150 mm diameter (corresponding e.g. to burst of a cooling pipe) RESUS provides the only safe way to return to the surface from more than 250 m.

or solid propellants. They differ with respect to the amount of gas produced by one generator, the gas temperature at the outlet of the gas duct and the composition of the produced gas.

The figure below shows the simulation of emergency surfacing of a 214-type submarine from 300 m comparing the performances of RESUS and highpressure air (HPA).

The Gas Generators are activated from the Control and Test Unit (CTU). The electrical signal from the CTU releases a pyro valve (liquid fuel generator) or activates an igniter (solid fuel generator). Once activated the gas generation cannot be stopped or reversed.

RESUS can be furnished with gas generators based on liquid

The gas production from the liquid propellant happens by catalytic decomposition of the fuel into a hot gaseous mixture; the solid propellant produces the pressure gas by combustion.

After 10 years the gas generators have to be refurbished at Airbus DS. Maintenance and inspection of the other RESUS system components can be done by the submarine crew and the navy shipyard. Dedicated test equipment and training courses for these tasks are supplied by Airbus DS. At present RESUS is installed on more than 30 submarines operated by the navies of Germany, Italy, Greece, Turkey, India and South Korea. FAM

Taking the Royal Navy into the 21st Century: Third of Britain's £1billion Astute class submarines finally takes to the water Edging slowly out of her dry dock at Barrow-in-Furness, this is the third of the Astute class submarines that will take the Royal Navy's fighting capabilities into the 21st Century. The 97m long, 7,400 tonne nuclear-powered attack submarine Artful has cost taxpayers more than £1billion but, along with its sisters, sets a new standard in weapons load and stealth.

Armed with both Spearfish heavy torpedoes and Tomahawk cruise missiles, Artful's design marks a shift away from a Cold War focus on anti-submarine warfare to a concept of 'Maritime Contributions to Joint Operations'. The Tomahawk cruise missiles she will carry are claimed to have an accuracy of just a few metres over a range of within 1,240 miles, giving Artful the ability to support ground forces anywhere in the world.

More than 39,000 acoustic tiles mask the vessel's sonar signature, meaning she slips through the seas with less noise than a baby dolphin. Yet her sonar is said to be so powerful it can detect ships leaving harbour in New York City from a listening point below the waters of the English Channel, 3,000 nautical miles away.

Artful got her toes wet for the first time yesterday, more than 24 hours after she first emerged from the Devonshire Dock Hall in Barrowin-Furness, Cumbria. She was officially named last September by Amanda, Lady Zambellas, wife of the Royal Navy’s First Sea Lord, Admiral Sir George Zambellas.

Stuart Godden, Astute Programme Director for BAE Systems, said: 'The launch of Artful is another significant step forward in the Astute programme. 'Building on past experiences we’ve been able to launch her in the most advanced state of construction of any submarine to be built in Barrow. This allows us to now fully concentrate on the test and commissioning activities required to get her to sea.

'Moving a submarine of this size from its build hall to the water is very challenging. It’s testament to the experience and careful planning of the team involved that Artful is now ready for the next phase in her programme. 'Witnessing a submarine move out of the hall and be readied for launch is truly inspiring and a source of great pride to the thousands who have played a part in getting Artful to this stage.'

Artful will now undergo a series of complex tests to prove the safety and operability of her systems before she departs BAE Systems’ site for sea trials.

The Ministry of Defence’s Director Submarines, Rear Admiral Mike Wareham, said: 'The Astute programme is making real progress and the sight of the third submarine afloat in the water is a reflection of the hard work of both the MOD and industry. 'The launch of this submarine brings it a step closer to entering into service where it will provide a key capability for the Royal Navy and an essential component of the Submarine Service into the future.'

BAE Systems, the prime contractor in the Astute programme, is the UK's only designer and builder of nuclear powered submarines - one of the most complex engineering programmes in the world. The first two submarines in the Astute class – HMS Astute and HMS Ambush – have now been handed over to the UK Royal Navy, while the remaining five are in various stages of construction. FAM

NATO’s Nemo Helps Navies Hone Submarine Rescue Skills May 21st, 2014. Dynamic Monarch 2014, which is currently underway off the coast of Poland, is the world’s largest submarine rescue exercise. It is designed to test international forces’ interoperability and ability to respond to submarines that have become disabled anywhere in the world.

The Russian Kursk disaster in August 2000 caused officials from the world’s navies to realise that due to differences in national escape egress systems, systems incompatibility would make submarine rescues difficult, if not impossible. As a result, most submarines today have switched to interoperable emergency egress systems, making it possible for humanitarian rescue efforts to occur using submersibles such as NATO Submarine Rescue System (NSRS).

During Dynamic Monarch 2014, Poland, NSRS has been mating with submarines from NATO member nations Poland and The Netherlands, and NATO partner Sweden.

60 degree list.”

“NSRS is a very safe and proven system to rescue the sailors of a stricken submarine,” said Senior Pilot Supervisor Tom Heron.

The Submarine Rescue Vehicle (SRV) component of NSRS, called Nemo, is capable of rescuing 12 sailors at a time during a stable emergency, or as many as 15 during a time of constrained emergency.

The 30-ton Nemo can be utilised world-wide, transported by plane or by ship, and can operate in excess of depths of 610 meters. The seven-year old submersible is owned by Norway, France and Great Britain.

When called upon, Nemo’s crew would be launched from the surface, manoeuvre to a stricken submarine, latch upon the sub’s egress hatch and then transfer sailors to the surface.

“The Nemo can operate underwater for up to four days,” Heron said. “When Nemo drops down to a submarine a great number of factors can determine the likelihood of affecting a rescue. Nemo can latch onto a submarine laying on the sea bottom at as much a

During Friday’s training, Nemo was lifted off its cradle on the Swedish vessel HSWMS BELOS and deposited into the Baltic Sea. After systems safety checks were performed Nemo submerged and approximately 35 minutes later dropped to a depth of 90 meters to latch onto the hatch of the Dutch submarine HNLMS BRUINVIS. The successful mating proved that in an actual emergency, Nemo could safely rescue the 60 BRUINVIS sailors.

“Dynamic Monarch is important because it brings together a wide variety of public officials from many countries working toward a common goal,” said Commander Jeroen Van Zanten, Royal Netherlands Navy. “It brings divers, technicians, engineers, and medical experts, who all come to work and observe these systems and build relationships for those who serve on the seas. Such operations serve to prove that we can do this, that it works and it builds confidence for our submariners who can see that these systems do work. They can see that in time of need they can be rescued.”

Exercise Dynamic Monarch 2014 wraps up on 22 May off the coast of Gdynia, Poland. FAM

SAES to produce diver detection sonar (DDS-03) with Gidropribor SAES and Gidropribor have signed a memorandum of cooperation for joint production and the commercialisation of Diver Detection Sonar (DDS-03). This agreement sets the stage for the introduction of the high frequency sonar DDS-03 into the Eurasian region (area of influence of the Caspian Sea). The high-frequency active sonar DDS-03 is specifically designed for the detection of underwater threats such as divers and manned and unmanned underwater vehicles (SDV, ROV or UUV), offering protection and surveillance against the potential threat they could represent in ports, critical facilities, shipwrecks, environmentally protected areas, special events and anchored boats.

As a result of this agreement, the DDS03 has been presented at the stand of GIDROPRIBOR in the Kazakhstan Defense Exhibition KADEX 2014, arousing the interest of visitors, since in recent years has increased awareness around the need for protection of ports, vessels and critical infrastructure against underwater threats in the Caspian Sea area. This protection requires the use of highly specialised sensors, characterised by a high probability of detection and low false alarm probability, such as the DDS03. SAES has strengthened its commercial efforts on the Eurasian area by attending the MAST EurAsia 2014 Conference, a specialised conference on magnetic and electrical radiations emitted by cruise ships. SAES specialises in underwater multi-influence measurements (acoustic, magnetic, electrical, seismic and pressure) and is conducting a series of studies designed to mitigate the lack of information of non-acoustic radiation of ships.

In the knowledge area of underwater signatures, the company is positioned at the forefront of the market with the SAES' manufactured last generation Multi-influence Range System (MIRS). FAM

SAES FINALIZES THE INTEGRATION TEST OF THE TOWED ARRAY HANDLING SYSTEM (TAHS) MADE FOR NEW SPANISH SUBMARINES S-80 SAES has successfully completed integration testing of the Deployment and Recovering System (TAHS) with Digital Towed Sonar (DTAS), also made by SAES, ending a comprehensive STW (Settingto- work) test plan on land in the own facilities, with more than 40 deployments completed without failure.

DTAS&TAHS Test Facilities SOLARSUB S-80 DTAS & TAHS (Digital Towed Array Sonar & Towed Array Handling System) is the third generation of long-range towed array sonar for submarines based on digital technology (DTAS) developed by SAES for the new S-80 submarines for the Spanish Navy.

Last December, SAES finalized the integration testing of the System for Deployment and Recovering (TAHS) with Digital Towed Sonar (DTAS) at its sonar test facilities, located in “La Palma”, Cartagena. Over 40 deployment/recovering manoeuvres has been completed, equivalent to 40 missions since normally sonar is deployed only once per mission.

In addition, these facilities are prepared to conduct training and faults simulation of towed array sonar to submarine crew, since this is an exact replica of the system to install on S-80.

“The next step is the implementation of both systems on board the submarine and execute the Harbor Acceptance Test (HAT)” says the program manager.

DTAS provides a tactical advantage to submarine and TAHS adds the capability to Automatically deploy and recover the sonar without surfacing, facilitating navigation and manoeuvrability.

Additionally, SAES develop the Combat System HMI, the sonar simulator- stimulator (SIM-STIM) and part of processing signal. Also provides the Acoustic Classification system (SICLA), the Sonar Performance Prediction system (SEAPROF), the Tactical Simulator (SIMTAC) and offers a complete line of technical assistance and engineering in underwater environments and ASW..

US Approves USD 170 Million MK48 Mod 6 Sale to Turkey May 13th, 2014. The U.S. State Department has made a determination approving a possible Foreign Military Sale to Turkey for MK 48 Mod 6 Advanced Technology All-Up-Round (AUR) Warshot torpedoes and associated equipment, parts, training and logistical support for an estimated cost of $170 million.

The U.S. Defense Security Cooperation Agency delivered the required certification notifying Congress of this possible sale on May 12, 2014.

The Government of Turkey has requested a possible sale of up to 48 MK 48 Mod 6 Advanced Technology All-Up-Round (AUR) Warshot Torpedoes, containers, fleet exercise sections, exercise fuel tanks, surface recovery cage and tools, exercise hardware, maintenance facility upgrades, support and test equipment, spare and repair parts, personnel training and training equipment, publications and technical documentation, U.S. Government and contractor engineering, technical, and logistics support services, and other related elements of logistics support. The total estimated cost is $170 million.

“The Republic of Turkey is a partner of the United States in ensuring peace and stability in the region. It is vital to the U.S. national interest to assist our North Atlantic Treaty Organization (NATO) ally in developing and maintaining a strong and ready self-defense capability that will contribute to an acceptable military balance in the area. This proposed sale is consistent with those objectives,” the U.S. State Department said in its release.

The proposed sale will improve Turkey’s capability for self defense, modernization, regional security, and interoperability with U.S. and other NATO members. Turkey will use the enhanced capability of the MK 48 Mod 6 Advanced Technology torpedoes on the new CERBE Class submarines (214 Type 1200). Turkey has significant experience in maintaining and supporting advanced torpedoes, particularly MK 46 Mod 5A(S)W and MK 54 Lightweight Torpedoes (LWT),

and has capable infrastructure that will require minimal updates.

Turkey is capable of integrating, employing, and maintaining the MK 48 Mod 6AT Torpedo.

The proposed sale of this equipment and support will not alter the basic military balance in the region.

The principal contractor will be Raytheon Company Integrated Defense Systems in Keyport, Washington; and Lockheed Martin Sippican in Marion, Massachusetts. There are no known offset agreements associated in connection with this proposed sale.

Implementation of this proposed sale will not require the assignment of any additional U.S. Government or contract representatives to Turkey; however, contractor engineering and technical services may be required on an interim basis for installations. FAM

Spanish Navy Sailors Tour Naval Submarine Base New London May 13th, 2014. More than 40 midshipmen from the Spanish Navy visited Sailors at Naval Submarine Base New London in Groton, Conn., May 12, to learn about the U.S. submarine force.

The group drove three hours north from New York City two days after their training ship – a four-masted topsail, steel-hulled schooner called BE Juan Sebastian de Elcano – docked for a goodwill visit. The U.S. Navy coordinator Aluin Morales, protocol officer for Submarine Group 2, said the exchange was worthwhile because it “fosters and continues to grow the relationship with our NATO ally.”

Spain’s naval officers-in-training started visiting Groton annually in 2011. This year’s visit included a submarine force orientation briefing and tour of submarine training facilities. “I didn’t know you all change crews on some of your submarines,” said Midshipman 1st Class Ignacio Grueiro when asked what he learned.

Grueiro referred to a dual-crew concept that maximizes the time ballistic-missile and guided-missile submarines spend operating overseas. The concept was a common topic of interest for the visiting midshipmen. As a former enlisted Sailor who served in the Spanish Navy for 19 years, Grueiro said he was familiar with many aspects of the U.S. Navy, but the dual-crew concept for Ohio-class submarines was new to him.

“I don’t believe we could do that in our Navy,” he said. “We can’t maintain our ships at sea for as long as you do, or change an entire crew while forward deployed like some of your subs.”

Grueiro said he’ll likely serve on a Spanish frigate after graduating from Spain’s naval officer academy, the “Escuela Naval Militar de Oficiales.”

The midshipmen have been learning seamanship aboard Elcano, an 87-year-old vessel whose primary mission is to train Spain’s future naval officers. The ship’s crew includes 23 officers, 22 petty officers, 139 seamen and five civilian instructors. Elcano is scheduled to depart New York May 15, to sail back across the Atlantic. She will make stops in Ireland, Germany, and Norway before returning home to Spain. The ship is named for a Basque explorer who became the first sea captain to circumnavigate the world in 1522. FAM

HMAS Sheean Participates in Anti-Submarine Exercise May 19th, 2014. The Royal Australian Navy’s Collins-class submarine HMAS Sheean has taken advantage of a mid-ocean encounter by getting in some anti-submarine warfare practice on its way to Singapore for a major exercise.

HMAS Sheean will participate in Exercise Bersama Shield 2014 with other Australian Defence Force assets alongside the defence forces of New Zealand, Malaysia, Singapore and the United Kingdom in a critical test of interoperability.

On the way past Christmas Island, Sheean encountered the RAN Anzac-class frigate HMAS Stuart. The Commander of Australian Navy’s Maritime Operations, Commodore Brad Wheeler, said neither vessel could let the chance slip by without engaging in a battle of stealth.

“This is the type of warfare Sheean will be participating in during Bersama Shield so when this opportunity came up, we knew we couldn’t let it go,” Commodore Wheeler said.

“HMAS Stuart had a window in her schedule and hunting submarines is always a challenge.”

In the end, both ships called it a draw and Sheean continued on its way north.

HMAS Sheean and HMAS Sydney, as well as two RAAF AP-3C Orions, an E-7A Wedgetail and a KA350 King Air will participate in Bersama Shield 14, which will be held in and around the Malaysian and Singaporean coasts.

USS City of Corpus Christi Earns 2014 Ney Award May 16th, 2014. The Los Angeles-class fast attack submarine USS City of Corpus Christi (SSN 705) earned the 2014 Captain Edward F. Ney Award for best submarine galley in the U.S. Navy. The annual award, co-sponsored by the International Food Service Executives Association (IFSEA), encourages excellence in the U.S. Navy Food Service programs with the objective of improving the quality of life for the U.S. Navy personnel.

“Winning this award allows the Culinary Specialist division to be properly recognized for the hard work and persistent dedication they devote to the crew members on a daily basis,” said Lt. j.g. Franklin Roberson, the supply officer on board City of Corpus Christi. “The ability to maintain an exceptional operation speaks volumes for culinary specialists.” The Culinary Division on the City of Corpus Christi is made up of 10 Culinary Specialists who prepare three meals a day for the 150 crewmembers. “Teamwork was the key to success,” said Senior Chief Culinary Specialist Gerald Davis. “To accomplish this with such a young group of guys is my favorite part.”Many crewmembers stated that their high morale was in a large part due to the quality of the food served aboard.

“Everyone enjoys the food,” said Sonar Technician Submarines Seaman Stuart Wright. “To win this award lets us know we are getting the best food.” “I really like the variety, it’s the best,” said Wright, echoing other crew members with what they enjoy most of their galley. “We get everything from authentic southern country cooking to Asian and Hispanic foods.”

“It was a big morale boost for the whole boat, not only the Culinary Specialist Division,” said Culinary Specialist 3rd Class Joshua Bickert upon winning the award. “The whole crew was pulling for us to win it.” The Ney award is given to the ship that most successfully sets the standards for cleanliness in the galleys, quality of food, and overall service of the food support team. City of Corpus Christi is the second ship to be named after the Texas city, and is capable of conducting both anti-surface and anti-submarine operations along with guidedmissile strike operations using conventional Tomahawk Land Attack Missiles.

ASW SOLUTIONS FOR THE MODERN ASW FRAMEWORK

The emergence of new military technologies has dramatically affected to the traditional Concept of Operation of the Anti Submarine Warfare Missions (ASW). Modern submarines have technological advances in enhanced propulsion, quieting techniques and coordinated weapons technologies. In turn, new geopolitical scenarios in the world constrain naval forces involved in the ASW missions to the littoral waters (brown waters). The “way ahead” for ASW in the 21st Century is (a) to deploy the forces in a Secure Friendly Maneuver Area to enhance their security close to the coast, (b) to prioritize the use of smaller and faster combat ships (OPV, corvettes, FAC) able to share tactical and intelligence information exploiting the benefits of a Network Centric Warfare (NCW), (c) to use unmanned vehicles (UAV or USV) to deploy sonobuoys and relay the acoustic information either to combat ships or ground stations, (d) to have the ability to make quick and agile centralized decisions in order to drive all the deployed forces as if they were a single and powerful weapon.

n this new ASW context, and with the objective to continue at the forefront of the ASW systems, in the year 2004 SAES assumed the challenge of design and manufacturing a system capable to participate in these new ASW missions. The system is now a reality, the name:

SAES INDUSTRY SOLUTIONS SAES has been developing for over twenty-five years their expertise in underwater technology within the military naval sector. Over the years this skill has expanded to civil applications. SAES, recognised as a leader in its field, positions itself on Antisubmarine Fig.1 Simulation of the electric field radiated by a vessel (longitudinal, transverse and vertical components).

Sensor Data Link (SDL) system.

The SDL system is a new Anti-Submarine Warfare (ASW) solution providing a unique, fully integrated ship/air weapon system, initially designed to enhance and extend the ship acoustic sensors.

The SDL system controls remotely manned/ unmanned air vehicle in order to receive via data relay (STANAG 7085 compliance) the acoustic and tactical information from sonobuoys (passive, active and digital) deployed. Additionally the SDL system collaborates in a Network Centric Warfare (NCW) giving the ability to make quick and agile centralized decisions in order to drive all the deployed forces as if they were a single and powerful weapon.

This paper “ASW solutions for the modern ASW framework” will be explained in depth by Ignacio Gutiérrez Suanzes (head of ASW line of Business) in the UDT 2014 Exhibiting and Conference, on Thursday 12th Jun at 15:00 hrs (Conference “Underwater Communication”, Session “ASW Solutions for the Modern ASW framework”).

Next, are presented some of solutions that SAES can provide you.

SPAS Sonobuoy Processing Acoustic System The Sonobuoy Processing Acoustic System (SPAS) is an ideal tool to assure the success of an Anti Submarine Warfare Mission (ASW). The system SPAS detects, localizes and tracks submarines and surface ships based on analysis of acoustic signals acquired by deployed passive and active sonobuoys.

SAES has developed and manufactured an Acoustic Processing System Family (SPAS). The systems which take part of this family are capable to process from 4 (SPAS-4) to 32 (SPAS-32) passive and active sonobuoys simultaneously.

• Systems developed for MCM as the mine sweeping systems.

MIRS has been primarily designed using Commercial Off The Self (COTS) equipment for maximum reliability at minimum cost.

MIRS has two installations modes: can be located at a fixed station or, using the portable capability, can be located in the desired location, since it is easily deployable by two people from a rigid-hulled inflatable boat (RHIB).

• MILA MILA-6C is a smart computer controlled time-fuzzed underwater limpet mine. It can be fixed by frogmen onto the hull of the ships or be used as demolition charge as well. It has a conical shape and low weight in water.

MILA is available in Exercise (reusable & inert) and Combat versions.

NAVAL MINES Based on the experience in underwater sensors, SAES has developed a complete set of Multi-influence Naval Mines, at the forefront of the market, that use a variety of sensors to detect different physical influences.

• MINEA The family of MINEA products comprises three kind of naval mines: cylindrical bottom mine, conical shape shallow water mine and moored mine.
