The South African Army is purchasing night vision tubes worth R3 million from vendor ECM Technologies. The order was placed last month. It adds to the some R238 million spent on night vision equipment since 2007. In addition to the R241 223 912.08 spent on new equipment, some R17 241 102.51 has been spent on maintenance and repair. The equipment replaces dated technology based on first and second generation image intensifiers. The acquisitions appear separate from Project Cytoon that is seeing the SA Army Tactical Intelligence Corps gaining 14 Thales Squire ground surveillance radars and 65 Thales Sophie thermal imagers.

 

Thermal imagers detect radiation in the infrared range of the electromagnetic spectrum.

 

Since most objects emit such radiation, thermal imagers allow their users to "see" their surroundings with or without visible light. The warmer the object, the brighter the object appears in the imager. Humans, with an internal body temperature of 37 degrees Celsius tend to stand out against their surroundings, which are mostly cooler. This also allows thermal imagers to spot camouflaged targets. Many modern thermal imagers include an eye-safe laser rangefinder and pointer, a compass, GPS and digital camera. The Thales Sophie can spot humans at over 4km, tanks at 10km, helicopters at 12km and jet fighters at 16km, Thales says.

Le Holland a réalisé sa première sortie avant que l'I-Mast ne soit installé

04/05/2011 MER et MARINE

 

Le Holland, premier des quatre Ocean Going Patrol Vessels (OGPV) commandés aux chantiers Damen Schelde Naval Shipbuilding, a réalisé en avril ses premiers essais au large des côtes néerlandaises. Cette sortie en mer du Nord a porté sur la manoeuvrabilité et la propulsion, avec notamment une navigation de 4 heures à pleine puissance pour tester les équipements et la consommation en carburant. Pour ces premiers essais, le Holland n'était pas encore doté de son I-Mast IM-400, un mât intégré conçu par Thales et rassemblant la quasi-totalité des senseurs embarqués (radars, systèmes de détection, conduite de tir, télécommunications...) Cette structure, réalisée indépendamment du navire, sera montée une fois achevée sur le patrouilleur. Une fois en place, le bâtiment pourra débuter les essais de son système de combat et de son système d'armes, en vue d'une livraison à la marine néerlandaise en fin d'année. En tout, quatre navires de ce type ont été commandés (Holland, Friesland, Zeeland et Groningen) mais, en raison des restrictions budgétaires, les Pays-Bas ne devraient en conserver que deux, les autres étant proposés à l'export. Longs de 108.4 mètres pour une largeur de 16 mètres, les OGPV afficheront un déplacement en charge de 3745 tonnes. Répondant aux nouveaux enjeux en matière de menaces asymétriques et conçus pour lutter efficacement contre la piraterie ou le narcotrafic, les Holland auront un système de mise à l'eau pour deux embarcations rapides. Ils disposeront, en outre, d'un hangar et d'une plateforme pour un hélicoptère de type NH90. L'armement comprendra une tourelle de 76mm, un canon de 27mm télé-opéré, ainsi que de l'artillerie légère. L'équipage sera limité à 50 marins mais les bâtiments auront une capacité d'hébergement de 90 personnes. En cas de besoin, une centaine de naufragés pourra même être accueillie sur une courte durée. La propulsion, assurée par deux moteurs diesels de 5400 kW, permettra aux patrouilleurs néerlandais d'atteindre la vitesse de 21.5 noeuds et de franchir 5000 nautiques à 15 noeuds.

Eurotorp's MU90 LWT Takes a Further Step Towards Breakthrough for Air Platforms

03 May 2011 naval-technology.com

 

The MU90 continues its operational progression with the French Navy, following the delivery of the 200th MU90 light weight torpedo in July 2010 by the French Direction Générale de l'Armement (DGA).

 

Since then, the French Navy has started to deploy its first MU90 LWT for operational exercises in parallel with batch acceptance tests. During an advanced anti-submarine exercise in April 2011, the operational crew of one ATLANTIQUE2 (ATL2) maritime patrol aircraft (MPA) successfully performed tracking, classification and long range engagement of a CALAS autonomous target simulating a submarine. Thanks to using the MU90, the French Navy has made a significant step change in ASW capability. Following early operational capability validation in 2008 in partnership with Eurotorp, the French Navy has started to conduct exercises on its own with the MU90, helping the torpedo on its next step towards full operation.

 

Today, almost all the ATL2 have been modified to ensure the launching capability of the MU90. The MU90 airborne solution adopted for this aircraft is a semi-integrated one so as not to interfere with the aircraft data management system while being connected to the platform attitude data, thus granting maximum freedom of manoeuvre to the crew prior to the launch. This intermediate solution has minimised modifications on board the aircraft without degrading any of the MU90’s performance. The MU90 is preset through the very user-friendly 'PCA' semi-integrated airborne presetter, providing the TACCO the full range of MU90 presets through pre-defined scenarios in which every preset can be modified if needed. The success of MU90 air launches demonstrates the full efficiency of MU90 when embarked on board any air platform.

 

Of 324mm diameter, the MU90 can be embarked on board any type of ASW air fixed or rotary wing aircraft. In addition to ATL2, the MU90 is qualified on board NH90, Lynx, EH101 Merlin, SH-2G Sea Sprite with different solutions ranging from stand-alone to fully integrated ones, through specific equipments or aircraft store management system. MU90, offering an unmatchable flight domain up to 900m in altitude and 400kts in speed, is today a candidate to be embarked on board all anti-submarine warfare air platforms, including the helicopters Panther, AW159, S70B, MH-60R and MH92 as well as the maritime patrol aircraft C295, ATR72, Dash8, P3C and P8. Eurotorp is already in advanced talks with the majority of air platform suppliers to achieve this goal.

 

The MU90 is a fire-and-forget weapon designed to counter any type of nuclear or conventional submarine, acoustically coated, deep and fast-evasive, deploying active or passive anti-torpedo effectors. The torpedo features unique system characteristics which allow real operational capability in coastal waters. The MU90 is powered through a closed-loop aluminium–silver oxide sea water battery delivering twice the energy of all the other LWTs as well as total safety. It is equipped with a fully-insensitive directed energy shaped charge warhead, proven to penetrate double-hulled large submarines, advanced acoustic head and last generation mission software. Of extremely long endurance, the engagement distance is beyond 12,000m, whatever the submarine depth. The MU90 operates without any speed degradation and without any limitation of salinity and temperature at depths >1000m or as shallow as 25m, whilst retaining navigation capability up to 3m.

 

The MU90 LWT is in service with the French, Italian, German, Danish, and Polish Navies, and has also been delivered and accepted by the Commonwealth of Australia (CoA). In France, the MU90 is embarked on board F70 and Horizon frigates, ATL2 MPA and Lynx helicopters. It will be also embarked soon, in France and in Italy as well, on board FREMM frigates and NH90 helicopters.
