  Royal Air Force Typhoon jets to receive key sensor upgrade

  By: Andrew Chuter WARTON — With a complex weapons integration program squared away, giving Royal Air Force Typhoon jets more punch, key sensors on the jet could see an upgrade. The RAF's test and evaluation squadron is already test flying the Litening 5 targeting pod in order to optimize its operation by Typhoon pilots. Work is also underway to update and improve the reliability of the jets Pirate passive infrared airborne track equipment, said Andy Flynn, BAE System's Typhoon capability director. Known as Project Centurion, the British late last year completed integration of MBDA's Meteor, Brimstone and Storm Shadow missiles on Typhoon in 47 months. At a cost of around £425 million, or $515.83 million, the program allowed the RAF to stand down the entire fleet of Tornado jets that had provided the primary strike capability. Flynn told reporters during a briefing at the company's Warton combat air site in northwest England Aug. 7 that the sensor work was “the next iteration of Centurion.” “Agile spiral development and keeping the aircraft relevant is the phase we are in. We have done the big leap and it's now about keeping it relevant,” he said. The Tornado was a two-seat aircraft, whereas the Typhoon is single seat. Flynn said the work on the Litening 5 was about easing pilot workload. “What we are doing now is getting the feedback from customer and operations teams on how to make that tasking simpler and really increase the cycle time on ops. We've already got Litening 5 pods up in the air as an iteration and we are seeking feedback from 41 Squadron [the test and evaluation squadron], ” he said. The plan is to get the enhanced capability “out to the front line by the end of next year,” said Flynn. Development phase work is also underway on a new iteration of Pirate as well improving the reliability and robustness of the sensor. “That work is in the development phase and we are doing that over the Autumn period. What we are doing on Typhoon overall is really enhancing the sensors capability as well making the workload easier for the pilot,” said Flynn. The sensor changes are a small part of a wider capability update on the Typhoon to keep aircraft relevant until they go out of service, currently set for 2040. On the horizon for the RAF is a new e-scan radar, known as Radar 2, which is being developed for the British by Leonardo; the new BAE Striker II helmet; and networked enabled weapons. But, Eurofighter, the Airbus, BAE, and Leonardo industrial partnership responsible for the development and production of the Typhoon, is also conducting a review of future potential updates to the fighter. Eurofighter announced at the Paris Air Show in June a deal valued at 53.7 million euros with the NATO Eurofighter & Tornado Management Agency, or NETMA, to undertake a long-term evolution review of the fighter and the EJ200 engine over the next 19 months. NETMA represents the British, German, Italian and Spanish governments. Flynn said there were more than 50 separate candidate technologies being considered by the evolution review. Some of those potential upgrades could also find themselves cross decking to the Tempest sixth-generation fighter now being proposed by the British. Clive Marrison, the industrial requirements director for Team Tempest, the industrial/government partnership leading the next-generation fighter work , said both jets could benefit from close development ties. “Typhoon could benefit from some of the technologies that Tempest is looking at and by the same token Tempest could benefit from some of the technologies that Typhoon is investing in,” said Marrison. For example: Some of the cockpit and helmet work BAE is doing might allow industry to offer some of those technologies back into Typhoon, said Marrison. While the BAE executives were looking into the future for British combat air capabilities, the Typhoon approaches a landmark of sorts to be celebrated. Sixteen years after taking delivery of its first Typhoon, the RAF is preparing to receive the final aircraft ordered for its fleet in the next few weeks, said Flynn. The final aircraft in a British order for 160 Typhoons made its test flight recently and is due to be handed over to the RAF in the coming weeks. Completion of the order leaves 24 aircraft destined for Qatar on the order book for BAE, although it is also building parts of the Typhoons sold to Kuwait by Eurofighter partner Leonardo. Three equipment sets have so far been completed at BAE's Samlesbury plant near Warton, destined for the Leonardo assembly site in Italy. Flynn said the Qatar build program was just getting underway. The 24 aircraft order will see deliveries start in 2022 with completion set for 2024. https://www.c4isrnet.com/global/europe/2019/08/08/royal-air-force-typhoon-jets-to-receive-key-sensor-upgrade/

  Les frégates de la classe Nansen souffrent d’un défaut sérieux de conception. Le chantier Navantia mis en cause

  (B2) Un premier rapport du bureau enquêtes accidents norvégien (AIBN) l'affirme sans ambages. La collision entre une frégate de la marine norvégienne KNM Helge Ingstad et un tanker maltais (Sola TS) dans la baie de Hjeltefjorden en Norvège le 8 novembre, révèle un problème grave de conception sur certains navires fabriqués par les chantiers navals espagnols Navantia. Une alerte sécurité vient d'être envoyée Un naufrage à proximité des côtes Rappelons-nous, c'était juste après l'exercice de l'OTAN Trident Juncture, la frégate norvégienne (qui porte le numéro de coque F-313), effectuait des manœuvres à proximité des côtes, près du terminal pétrolier de ce fjord norvégien situé non loin de Bergen, quand il heurte le pétrolier qui naviguait en sens inverse. La collision ne provoque que peu de dég'ts dans le pétrolier, mais pour le navire militaire les conséquences sont autrement plus graves. Une enquête des bureaux d'accidents civil et militaire norvégiens La frégate norvégienne, qui fait alors partie de la force navale permanente de l'OTAN (SNMG1), est atteinte « au-dessus et au-dessous de la ligne de flottaison » et « absorbe énormément d'eau » comme le signale le ministère norvégien de la Défense. Il n'est plus stable et doit être échoué. Ses 137 marins doivent être évacués. Une enquête est alors diligentée associant le bureau d'enquête accidents maritime norvégien (AIBN) et son pendant militaire (DAIBN), auquel est associé l'unité d'enquête maritime maltaise (MSIU), autorité du pavillon du pétrolier. Les compartiments non étanches Trois compartiments étanches à bord du KNM Helge Ingstad sont inondés : « la salle du groupe électrogène arrière, les quartiers de l'équipage du pont Orlop et le magasin » selon le rapport de l'AIBN. La stabilité est jugée « médiocre », mais le navire est encore considéré comme 'sauvable'. Cette première évaluation ne résiste pas. L'eau gagne du terrain. Elle « coule de la salle des génératrices arrière vers la salle des engrenages via les arbres creux de l'hélice, puis de la salle des engrenages, vers les salles des machines avant et arrière via les boîtes de rangement dans les cloisons ». Quand la salle d'engrenage est inondée, l'évacuation des 137 marins est décidée. Le navire est considéré comme « perdu ». Huit marins sont légèrement blessés dans les différentes manœuvres. Le navire échoué coule à pic Les autorités espèrent encore pouvoir récupérer le navire, qui flotte toujours, en le fixant avec des c'bles. Mais dans la nuit du 12 au 13 novembre, ils s'arrachent et le navire coule à pic. Le navire est désormais considéré comme irrécupérable, même si les travaux sont toujours en cours pour être renfloué, comme le précise le ministère norvégien de la Défense. Perte sèche : 4,2 milliards de couronnes (environ 220 millions d'euros). Une enquête nécessaire chez Navantia L'autorité norvégienne préconise une vérification des navires norvégiens de même conception. Oslo dispose encore de quatre navires de la même classe — le KNM Fridtjof Nansen, le KNM Roald Amundsen, le KNM Otto Sverdrup et le KNM Thor Heyerdahl — construits sur les chantiers navals espagnols de Ferrol de Navantia. Elle demande ainsi à Navantia de mener « une enquête sur les problèmes identifiés lors de la première enquête et de déterminer s'il s'agit également d'un problème lié à d'autres navires ». L'industriel espagnol doit aussi envoyer une notification aux chantiers, propriétaires et exploitants concernés, pour leur indiquer « les mesures à prendre pour assurer la sécurité ».
