La Royal Air Force prépare activement la mise à jour de sa flotte d'avions de combat Eurofighter « Typhoon II » en vue du remplacement du Panavia Tornado GR4. En effet, les dernières unités de « Tornado » devraient être retirées au début de l'année 2019.
Project Centurion :
Le programme « Poject Centurion » doit permettre à l'avion européen d'égaler la capacité d'attaque au sol du « Tornado » et de la dépasser à terme.
Pour remplacer complètement le « Tornado » au sein de la RAF, les « Typhoon II » devront porter les mêmes armes, avec la phase 2 et phase 3 d'amélioration (P2EA et P3EA) qui, à leur tour, constituent la première phase et la deuxième phase du programme « Centurion ». Ils ont été précédés d'un Phase Zero (P1EB ou Phase 1 Enhancement Further Work). La phase zéro a été livrée en décembre 2017, officiellement entrée en service en janvier 2018 et est désormais opérationnelle dans le cadre de l'opération «Shader».
La configuration du projet « Centurion » est destinée à combiner la bombe guidée de précision Raytheon Paveway IV déjà livrée avec les missiles « Storm Shadow », « Meteor » et « Brimstone » sur le Typhoon FGR4. L'avion devra prochainement venir remplacer le Panavia Tornado GR4 au début de l'année 2019.
Les avions de première phase qui sont livrés ont été équipés de la mise à niveau « Typhoon » Phase 2 Enhancement (P2E) qui comprend le « Meteor » et le « Storm Shadow ». La phase 2 du projet Centurion couvre la mise à niveau de la phase 3 du Typhoon Enhancement (P3E) avec l'arrivée du « Brimstone ». Les essais sont maintenant en cours, la configuration finale du projet « Centurion » devrait être prête pour la fin de 2018.
Les appareils concernés font partie de la Tranche 1 (51), la Tranche 2 (67) et environ 10 appareils de la Tranche 3. A noter que 24 Eurofighter de la tranche 1 qui doivent être retenus serviront uniquement à la défense aérienne et ne recevront pas la mise à niveau du projet Centurion.
Environ 65 à 75 sorties devraient être enregistrées avant qu'une phase d'évaluation opérationnelle ne commence à au sein de la base aérienne de la RAF de Coningsby dans le Lincolnshire le 10 août prochain. Cela comprendra également des essais de tir complets avec l'arme de précision.
D'autres améliorations incluent des mises à jour de l'interface homme / machine du "Typhoon", avec notamment le système de visée monté sur un casque Striker fourni par BAE.
Le Storm Shadow :
Le SCALP (acronyme de « Système de croisière conventionnel autonome à longue portée »), anciennement « Arme de précision tirée à grande distance », est un missile développé fin 1994 MBDA. La version britannique est baptisée «Storm Shadow». Cette arme est conçue pour frapper l'ennemi dans son territoire profond, quelle que soit la défense aérienne gr'ce à sa furtivité qui le rend indétectable, y compris par les avions radars.
Le MBDA Brimstone :
Le missile Brimstone air-sol britannique fabriqué par MBDA sur commande de la Royal Air Force. Il est équipé d'un guidage laser et d'un radar millimétrique, ceci afin de le rendre plus efficace contre des cibles mobiles.
Le missile Meteor :
Le Meteor est prioritairement réservé aux missions d'interception à grande distance, au-delà de la portée optique (BVR) de tout type d'aéronefs. Son utilisation est privilégiée pour les cibles de haute valeur telles que l'attaque à plus de 100 km d'avions radar ou de ravitailleurs.
Ce missile va permettre d'assurer une efficacité de destruction à des distances aujourd'hui encore importantes, de l'ordre de 50 Nm (entre la cible et l'avion tireur au moment de l'impact).
A cette fin, le système d'arme comporte :
Un radar de bord qui fournit des informations précises sur la cible avant le départ du missile, et une liaison de données de type Link16 assurant les mêmes fonctions en retransmettant vers l'avion tireur les informations d'un capteur porté par un autre aéronef.
La propulsion de ce missile est également un défi technologique du fait du concept retenu : celui d'un statoréacteur. Ce statoréacteur à propergol solide et à poussée régulée (Throttleable Ducted Rocket ou TDR) dans sa phase de croisière comporte un accélérateur à poudre intégré dans la chambre de combustion, ce qui permet de donner une impulsion initiale suffisante pour atteindre une vitesse compatible avec le fonctionnement du statoréacteur.

Steve Trimble The U.S. Navy's MQ-25 is being developed as a carrier-based aerial refueler, but an intelligence agency is showing interest in the unmanned aircraft system for a maritime surveillance role. The National Geospatial-Intelligence Agency (NGA) has commissioned Boeing to study the integration requirements for installing the company's Multi-Mission Pod (MMP) on the MQ-25. Boeing developed the MMP using internal funding for the P-8A, a submarine hunter derived from the 737NG. It is designed to carry multiple payloads, including communication and electronic intelligence receivers. The NGA-sponsored study will evaluate how to use the MMP to introduce the agency's “maritime program” on the P-8A and MQ-25 fleets. The agency on Sept. 30 published a “justification and approval” notice for the study contract awarded to Boeing in May. Such notices are required to justify any contract awarded to a single contractor without a competition. In this case, the sole source award was justified because the MQ-25 is still early in the development phase, the NGA says, so Boeing is the only company that has access to the design data. The Navy awarded Boeing an $805 million in August 2018 to deliver four MQ-25 aircraft during the engineering and manufacturing development phase. The overall value of the deal has since risen to $944 million, of which $436 million, or 46.1%, has been obligated, according to the USASpending.gov procurement tracking site. Last month, Boeing completed the first flight of a company-funded test asset for the MQ-25 program at an airport in Illinois. The study also suggests the P-8A and MQ-25 fleet could be used to help replace the electronic intelligence capability once performed by the Lockheed EP-3E fleet. The Navy has said that the EP-3E will be replaced by a family of manned and unmanned aircraft, including the P-8A and the MQ-4C unmanned aircraft system. https://aviationweek.com/defense/intel-agency-studies-mq-25-surveillance-role

Trump is angry that a number of NATO nations haven't met an agreement, reached five years ago, to spend two per cent of their annual Gross Domestic Product on defence DAVID PUGLIESE, OTTAWA CITIZEN Another NATO summit brings another chance for U.S. President Donald Trump to browbeat America's allies for not spending enough on defence. Trump is angry that a number of NATO nations haven't met an agreement, reached five years ago, to spend two per cent of their annual Gross Domestic Product on defence. But that GDP yardstick has been rendered almost meaningless this year as the tiny nation of Bulgaria has joined the U.S. super power as being one of NATO's top military spenders. Bulgaria's GDP is so small that by purchasing eight F-16 fighter jets in a one-time outlay of $1.5 billion, the country will now be spending 3.25 per cent of its economic output on its military. Only the U.S., which spends 3.4 per cent of GDP on defence, is higher. Using the GDP measurement means that Estonia, which has one of the smallest navies in the world with four ships, has reached the NATO gold standard of two per cent. Canada, which spends more than 20 times the amount in actual dollars on its military, is viewed as a NATO deadbeat. For that reason, both Conservative and Liberal governments have pushed back on the GDP measurement, which was agreed to by NATO nations at a summit in Wales in 2014. Prime Minister Stephen Harper, arguably the most supportive leader of the Canadian military that the country had seen in decades, dismissed the notion of reaching that two per cent target, even though Canada signed on to the goal. At the Wales summit, Harper's staff pointed out that reaching the two per cent mark would have required the military's budget to almost double, something that was not fiscally or politically possible. Harper himself had come under fire from defence analysts who pointed out that under his government, the percentage of GDP spent on defence reached almost an all-time low of around 1 per cent. But Harper countered that it's the amount of actual spending and capability of a country's military that matters, not the GDP measurement. Prime Minister Justin Trudeau was essentially using the same argument Tuesday when he met with Trump at the NATO summit. “I think it's important to look at what is actually being done,” with defence dollars, Trudeau said. Canada only spends about 1.3 per cent of GDP on defence. But tabulate the defence dollars actually being spent on the military and Canada ranks an impressive sixth among the 29 NATO nations. The Liberal government's defence policy has promised even more money in the future. Military spending is set to increase from the current $21.8 billion to $32.7 billion in 2026-2027. Trudeau also noted in his meeting with Trump on Tuesday the key role Canada is playing in NATO operations in both Latvia and Iraq. Germany has taken a similar approach to the one used by Canada's Conservative and Liberal governments. It believes the amount of money actually being spent on military forces is more important than measuring it as a percentage of the GDP. Germany has also pointed out it is the second largest provider of troops for NATO operations. Trump is expected to once again criticize Germany for its level of defence spending. But the country does not seem to be in a hurry to make the two per cent goal. Germany currently spends about 1.4 per cent or around $64 billion annually. Earlier this year it told NATO it would reach 1.5 per cent of GDP by 2024. The other issue facing the Department of National Defence and the Canadian Forces related to the two per cent goal is one of capacity. Even if the defence budget was boosted to meet two per cent, the department simply doesn't have the ability to spend that amount of money. Around half the defence budget is for salaries and while the senior military leadership would welcome an increase in the ranks the problem they face is that young Canadians aren't exactly rushing out to join the forces. The military could spend more money on acquiring additional equipment. But a lack of trained procurement staff has been an obstacle standing in the way of even getting approved programs underway. Trudeau's explanation Tuesday about Canada's military spending being on a steady increase seemed to placate Trump, at least for now. The U.S. president responded that he views Canada as “slightly delinquent” when it comes to defence spending. “But they'll be okay,” he told journalists. “I have confidence. They'll get there quickly, I think.” https://ottawacitizen.com/news/national/defence-watch/analysis-natos-defence-budget-formula-is-flawed-and-canada-isnt-going-to-meet-its-target
