EA-18G Growler aircraft. (US Navy)

EA-18G Growler aircraft. (US Navy)

 

August 11, 2014: Strategy Page

 

Between May and June 2014 the U.S. Navy conducted tests using a Nimitz class carrier off the coast of California to determine if there was any benefit in expanding the EA-18G "Growler" electronic warfare aircraft squadron on each Nimitz class ship from five aircraft to eight. The tests were a success and the navy is trying to use that success to get Congress to provide cash to buy another 33 EA-18Gs to expand the squadrons on all the large carriers. The navy has enough support in Congress to get some additional EA-18Gs but defense budgets are being cut and there are too many worthy (or not) projects seeking cash that is not there anymore. The EA-18G manufacturer would like to keep production going into 2017 but it looks like they’ll be lucky to keep the line going into 2016.

 

Meanwhile the navy is getting some money for EA-18G upgrades. In 2013 that included new communications technology that allows the EA-18G to share data instantly with other EA-18Gs and other types of aircraft (combat and support, like E-2 and E-3 AWACS). The new capability is JTIDS (Joint Tactical Information Data System). Development (by the U.S. Air Force) of this system began 30 years ago and mature examples of the technology only began showing up in the last decade. JTIDS is a datalink that gives the pilot complete and real-time situation reports, showing what other pilots (and planes like the E-3) are seeing. Pilots who tested JTIDS reported drastic increases in their situational awareness (a “sense of where you are”). For example, during combat training exercises pilots with JTIDS had a 4-to-1 kill ratio in their favor against pilots without JTIDS.

 

Noting results like this the navy began adopting JTIDS, not only to improve the capabilities of its own aircraft but also to improve data sharing with air force warplanes, which often carry out joint operations with the navy. JTIDs is just one of several new technologies navy aircraft will need to get their “combat Internet” working. The EA-18G was the first navy aircraft to test JTIDS because the EA-18G is designed to work with air force and navy aircraft as the EA-18G now provides electronic warfare support for both services.

 

 EA-18G saw combat for the first time over Libya in 2011 and got to use a lot of its high tech gear in combat for this first time. This included the ALQ-99 radar jamming pod and an APG-79 phased array (AESA) radar, which also has some jamming capability (via the right software) as well as the ability to fry electronics. It was suggested that the EA-18G might have done this to some Libyan armored vehicles.

 

It was only in 2007 that the navy received its first operational (as opposed to developmental) EA-18G and in 2008 the first EA-18G squadron entered service. In early 2014 the hundredth EA-18G was delivered and there are only 17 to go on the original order. Meanwhile the U.S. Air Force and Marine Corps are planning on developing an electronic warfare version of the new F-35, or use a UAV, if the EA-18Gs are not plentiful or powerful enough to provide all the electronic protection needed in future wars.

 

The EA-18Gs have replaced the aging navy EA-6Bs that long provided electronic protection against enemy radars and missiles for navy and air force aircraft. The air force retired their EF-111 electronic warfare aircraft in 1998, on the assurance that the navy would get the EA-18G into service before the EA-6Bs died of old age. The older 27 ton EA-6B carries a crew of four, while the highly automated 29 ton EA-18G will have only 2 people on board. The EA-18G carries up to 5 electronic warfare pods, plus 2 AMRAAM air-to-air missiles and 2 anti-radiation (HARM) missiles. It may be the last manned aircraft to handle the EW job. UAVs are becoming more capable and will eventually take over this dangerous task.

11 August 2014 naval-technology.com

 

The US Navy's fifth Nimitz-class nuclear-powered aircraft carrier USS Abraham Lincoln (CVN 72) has received the 38ft upper mast section as part of its refuelling and complex overhaul (RCOH), at Huntington Ingalls Industries' Newport News Shipbuilding.

 

The installation marks a major milestone in the ship's RCOH programme.

 

Newport News Navy programmes vice-president Ken Mahler: "Since we began the refuelling complex overhaul, we've been working side-by-side on this project to recapitalise and modernise the entire ship, such that when she returns to service, Lincoln will continue to be one of the most capable and formidable ships in the world."

 

During the RCOH process, the company replaced the original round mast pole with a modified, tapered square pole, to increase strength and keep electrical piping systems enclosed.

 

The square pole includes waist-high rails and easier access to all areas via internal ladders.

 

The RCOH process, which is performed as part of the navy's $2.6bn cost-plus-incentive-fee contract awarded in April 2013, also includes the refuelling of the ship's reactors, painting of the hull, an upgraded system and a complete recapitalisation.

 

Armed with three Raytheon GMLS Mk29 eight-cell launchers for Nato Sea Sparrow surface-to-air missiles, the 317m-long Nimitz-class ships can accommodate more than 6,000 personnel and cruise at a maximum speed of over 30k.

 

Upon the scheduled redelivery in October 2016, the 102,000t USS Abraham Lincoln will continue to operate for another 25 years.

Qatar et USA : Un Contrat de $11 Milliards pour des hélicoptères Apaches

 

10.08.2014 Philippe Eyal-Koren (Tel Aviv) – Israel Valley

 

Les leaders israéliens installés à la Kiria, le Pentagone israélien situé au coeur de Tel Aviv, sont perplexes et se posent des questions (avant la guerre Gaza/Israël les militaires israéliens étaient “muets” sur les méga-deals d’armes avec le Qatar) : quel est l’état réel de la coopération entre le Qatar, qui finance le Hamas, et les producteurs d’armes américains ?

 

Le correspondant militaire du journal Haaretz, dans son édition de Dimanche, donne des chiffres assez impressionnants sur les ventes d’armes des Etats-Unis au Qatar. Il s’agit de la vente en 2014 d’Apaches (l’hélicoptère Apache est constitué de plus de 6 000 pièces fabriquées dans le monde entier, notamment au Royaume-Uni, aux Pays-Bas et en Irlande), de missiles, et des roquettes anti-tanks pour un montant total de 11 Milliards de dollars.

 

Le Qatar aurait acheté en 2014 au moins 24 exemplaires de l’Apache (livrables entre 2015 et 2016). Pour se faire une idée du contrat : la Grèce a pour sa part acheté récemment douze Apache AH-64D pour un coût total de 675 millions de $ (incluant probablement les armes et la maintenance), soit un prix unitaire de 56,25 millions de $.

 

A SAVOIR. Un hélicoptère d’attaque est un hélicoptère militaire conçu pour attaquer des cibles au sol, notamment des unités d’infanterie, des véhicules blindés et des bâtiments. Il est généralement équipé de mitrailleuses lourdes, de roquettes et de missiles air-sol. Il est parfois aussi muni de missiles air-air, surtout dans une tactique d’auto-défense.

 

Les hélicoptères d’attaques sont principalement utilisés pour deux types de mission : L’appui aérien rapproché et les actions anti-char, afin de détruire des escadrons de véhicules blindés. Ils sont parfois aussi appelés pour protéger des hélicoptères plus légers lors de missions de reconnaissance.

 

Alors que les hélicoptères ont été efficaces comme “tueurs de chars” au Moyen-Orient, les hélicoptères d’attaque sont vus dans un rôle plus multifonctionnel. Des tactiques comme le tank plinking ont montré que les avions pouvaient être efficaces contre les chars, mais les hélicoptères restent uniques dans leur capacité à fournir à basse vitesse et basse altitude un appui aérien rapproché.

 

L’AH-64 Apache rivalise en popularité avec le Hind, son adoption par l’US Army n’y étant pas étrangère. Durant la fin des années 1970 l’armée américaine a ressenti la nécessité de plus de sophistication dans le corps des hélicoptères d’attaque, leur permettant de fonctionner dans toutes les conditions météorologiques.

 

L’AH-64 Apache a été largement utilisé pendant l’opération Tempête du désert avec un grand succès. Les Apache ont effectué les premiers tirs de l’offensive en détruisant des radars d’alerte rapide et de sites de SAM à l’aide de leurs missiles Hellfire. Ils ont ensuite été utilisés avec succès dans deux de leurs rôles opérationnels, dans l’attaque directe contre les blindés ennemis et comme artillerie aérienne pour l’appui des troupes au sol. Les attaques aux missiles antichar et au canon par les hélicoptères Apache, Cobra et Gazelle permirent de détruire de nombreux chars et véhicules de l’armée irakienne.

 

En 1999, pendant la guerre de Kargil, les forces armées indiennes constatèrent qu’il y avait un besoin en hélicoptères qui peuvent fonctionner à des conditions de haute altitude avec facilité. Les limites d’exploitation des hélicoptères d’attaque avec une charge utile élevée et une maniabilité limitée a mené l’Inde à l’élaboration du Light Combat Helicopter qui peut fonctionner dans les hautes altitudes. Cet hélicoptère sera utilisé par l’Indian Air Force et l’escadre aérienne de l’armée indienne.

US congressman supports Taiwan's RIMPAC bid, submarine plans

 

11 Aug 2014 Pacific Sentinel
 

The chairman of the US House Armed Services Committee said Thursday in Taipei that he supports Taiwan efforts to participate in the Rim of the Pacific exercise (RIMPAC) and to obtain a transfer of US technology to build its own submarines.

 

"We have some influence and we will push to see that they (Taiwan's armed forces) are invited next time" to take part in RIMPAC, Howard "Buck" McKeon (R-Calif) told CNA in an interview just before he and his congressional delegation wrapped up a two-day visit to Taiwan.

 

He said Taiwan's participation in the US-led RIMPAC, the world's largest international maritime warfare exercise, will help build a stronger relationship between Taiwan and the United States.

 

McKeon said the issue was raised during his meetings with Taiwan's defense minister, Yen Ming, and the National Security Council Secretary-General King Pu-tsung.

 

RIMPAC 2014, held June 26 to Aug. 1 in and around Hawaii, marked the first time that China took part.

 

McKeon, who arrived in Taiwan Wednesday as part of a trip to East Asia, also met with President Ma Ying-jeou Thursday. During the meeting, Ma reiterated Taiwan's desire to have diesel-electric submarines to strengthen the country's defense capabilities.

Five Scenarios for the South China Sea


11 Aug. 2014 Pacific Sentinel
 

A Vietnamese-American space scientist has published an article entitled Five Scenarios for East Sea on Hanoi-based online newspaper VietNamNet Bridge on August 1, analyzing the historical background of the Paracel Islands and Spratly Islands disputes, and arguing that Vietnam has never given up sovereignty over the former, as well as predicting five possible scenarios for the South China Sea–known as the East Sea in Vietnam–that may occur within the next ten years.

 

In the article Thai Van Cau said that in the first scenario, China will utilize military force to invade part of or the whole of the Spratly Islands in an attempt to "resolve disputes and establish sovereignty over the islands and its territorial waters by 2020," as Chinese scholars have suggested.

 

The precedent for this is China's use of military force against Vietnam in marine disputes during the 1970s and 1980s, he said.

 

China's military ventures in the Spratly Islands are motivated by its ambition to control all of the islands. This move is likely to destabilize the South China Sea region and affect marine traffic for countries such as the US, Japan, and India.

 

China has been monitoring the response of the US and the EU to the Ukraine crisis, to try and get an idea of the backlash that will be unleashed against it should the nation make any dramatic moves in the South China Sea, the report stated. The annexation of Crimea by Russia may not be the best guide for China to go by, however, due to geopolitical and economic differences, Thai said.

Aug. 8, 2014 - By ANDREW TILGHMAN – Defense News

 

President Obama says it all the time – no combat troops will return to Iraq.

 

But many experts believe it will be extremely hard to achieve Obama’s newly expanded military mission there without more Americans on the ground.

 

“I think the slippery slope analogy is the right one for Iraq right now,” said Barry Posen, director of the Security Studies program at the Massachusetts Institute of Technology.

 

On Thursday, Obama authorized a new open-ended operation in response to gains by the Islamic State militants in northern Iraq.

 

For now, the new mission relies on aircraft based outside Iraq. The U.S. will help defend the Kurdish city of Erbil from Islamic State fighters using “targeted air strikes,” Obama said. Those air strikes began Friday morning and included at least three separate bombings before noon, defense officials said.

 

The second mission is a commitment to protect some 40,000 Iraqi Yazidis who are trapped on a mountain surrounded by the militants. That began Thursday night with air drops of food and water for at least 8,000 people.

 

Military experts say tactical commanders will want more ground forces. Forward air controllers could provide more precise targeting information. U.S. advisers could support the Kurdish forces fighting the militants. And U.S. commanders may need to expand their intelligence effort on the ground.

 

In turn, U.S. forces might need a forward operating base with a security perimeter, more force protection and a logistical supply line. Medevac capabilities may require a helicopter detachment and a small aviation maintenance shed.

 

“You’re talking about a 10,000- to 15,000-soldier effort to include maintenance, and medevac and security,” said retired Army Col. Peter Mansoor, who served as executive officer to David Petraeus during the 2007 surge in Iraq and now is a professor of military history at Ohio State University.

 

“But that is the price you’re going to pay if you want to roll back [Islamic State]. You can’t just snap your fingers and make it go away,” Mansoor said.

 

Obama’s address to the nation Thursday night suggested that the city of Erbil will be a no-go zone for the militants, and he offered no timeframe for that commitment.

 

The biggest near-term military challenge stems from Obama’s commitment to prevent a “genocide” of the Yazidi people trapped on Mount Sinjar. The air drops providing food and water that began Thursday night are a short-term solution. Obama promised to use air strikes on Islamic State forces, if needed, to “break the siege” and “help refugees get the shelter and food and water they so desperately need.”

 

Getting the Yazidis off the mountain and safely transporting them to a secure location will require either an “an enormous helicopter air lift” or ground combat units to confront militants and secure a safe-passage corridor for the refugees, Mansoor said.

 

 

“That may require some kind of ground presence to escort them through enemy held territory,” Mansoor said.

 

“That is [IS] controlled territory. There could be major combat along the way. This could be very difficult,” Mansoor said.

 

'Leverage Locals'

 

The key to limiting ground-level involvement for U.S. service members will be coordinating with the Kurdish Peshmerga militia or other allied forces, said Mark Gunzinger, a retired Air Force colonel and senior fellow at the Center for Strategic and Budgetary Assessments.

 

“I don’t think this is headed down a slippery slope whatsoever,” Gunzinger said in an interview Friday.

 

He pointed to the success at the early stages of the Afghanistan war in 2001 when U.S. aircraft, working closely with small U.S. special operations teams and friendly Afghan forces, toppled the Taliban regime.

 

“I think that kind of model could be effective in Iraq,” Gunzinger said.

 

That model may be even more effective today because the U.S. military has far more drones to provide a constant presence overhead.

 

Also, there is little evidence that Islamic State forces have significant anti-aircraft weaponry, making an aggressive U.S.-led air campaign easier, Gunzinger said.

 

The analogy of Afghanistan in 2001 was also cited by Seth Jones, a counter-insurgency expert with the Rand Corporation. “Leveraging locals is the key,” Jones said in an interview Friday, adding that additional ground forces may be limited to small elements of forward air controllers and special forces teams.

 

While the need for U.S. ground troops may be limited, Jones said, Obama’s plan poses another risk: If air strikes are successful in the area around Erbil, pressure may grow for the U.S. to provide similar air strikes in other parts of Iraq. “The slippery slope may be a much broader demand for air strikes,” Jones said.

 

It’s unclear how far Obama and his military leaders plan to take this current campaign.

 

“There is still some question about whether this is going to be a major air campaign to defeat [the Islamic State] or whether it is going to me more along the lines of strikes and raids to deny them access and prevent them from making further advances. I’m not sure,” Gunzinger said.

 

Obama’s language Thursday was ambiguous, Posen said. Despite his repeated aversion to sending “combat troops” back into Iraq, Obama has signaled a long-term commitment to support the Iraqi military and a continued belief in a cohesive, Democratic Iraq in which Sunnis and Shiites and Kurds share power under a Bagdad led government.

 

“Is this going to be a limited mission? Or is this the beginning of a project where we are once again going to fix Iraq, to build a homogenous, unified Iraq?” Posen said. .

 

“If they are going to succumb to that logic, if they are going to try to build the beautiful outcome that the Bush Administration failed to build, then they are not edging up to the slippery slope — they are diving over it.”

WASHINGTON, 11août - RIA Novosti

 

Des avions militaires américains ont largué de nouvelles cargaisons d'eau et de vivres destinées aux civils bloqués dans les monts Sinjar (nord de l'Irak) par les djihadistes de l'Etat islamique,  a annoncé lundi le Pentagone dans un communiqué.

 

"Un C-17 et trois avions cargo C-130 ont largué 88 cargaisons de vivres qui fourniront de la nourriture et de l'eau pour des milliers d'Irakiens piégés sur les monts Sinjar", a indique le communiqué.

 

Selon le Pentagone, les Etats-Unis ont fourni depuis jeudi soir "plus de 74.000 repas et plus de 56.780 litres d'eau potable" aux membres de la minorité yézidi pourchassés par les djihadistes.

 

Appuyé par des sunnites irakiens et par d'anciens militaires de l'armée de Saddam Hussein, le groupe terroriste Etat islamique a envahi une vaste région irakienne englobant les provinces de Ninawa, de Salah ad-Din et d'Al-Anbar.

 

Le 29 juin dernier, l'EI a annoncé la création d'un "Califat islamique", le titre de calife étant attribué au chef de file de ce groupe djihadiste, Abdullah Ibrahim al-Samarrai, connu également sous le nom d'Abou Bakr al-Baghdadi.

 

Dans la nuit de jeudi à vendredi, le président américain Barack Obama a autorisé des frappes aériennes ciblées en Irak "pour aider les forces irakiennes qui se battent pour protéger les civils".

La BNS ne lâche pas l'industrie de l'armement

 

10 août 2014 20minutes.ch

 

Contrairement à ses déclarations d'intention, la Banque nationale suisse détient toujours des participations auprès de fabricants d'armes controversés.

 

La Banque nationale suisse (BNS) détient toujours des actions dans plusieurs entreprises de défense américaines d'une valeur supérieure à 250 millions de francs, rapporte l'hebdomadaire Schweiz am Sonntag.

Dans son rapport annuel 2013, la BNS avait pourtant annoncé ne plus vouloir miser dans des titres controversés liés à l'armement. «La Banque nationale a décidé en 2013 de ne plus investir dans des actions d'entreprises qui produisent des armes interdites à l'échelle internationale», avait-elle énoncé. Depuis, la BNS a confirmé, durant le premier semestre de l'année, ses participations dans les entreprises américaines de défense Honeywell International et Lockheed, en les renforçant même à 66 millions de francs, respectivement 43 millions de francs. Les deux sociétés sont notamment accusées par des organisations des droits de l'homme, mais aussi par l'Etat norvégien, de fabriquer des armes nucléaires.

Les participations de la BNS dans Raytheon et General Dynamics sont encore plus controversées. Les deux firmes sont toutes les deux suspectées d'être impliquées dans la fabrication de munition. La Banque nationale n'a pas voulu s'exprimer sur ces participations. Elle affirme se baser sur des analyses de titres effectuées par des institutions bien établies. Elle se serait néanmoins quand même séparée de participations au sein de la firme Textron active dans la fabrication de munition.

Les actions des sociétés actives dans l'armement ont la cote ces derniers mois avec la hausse du nombre de conflits militaires et les incertitudes géopolitiques.

Les Etats-Unis renforcent les capacités de la Marine burundaise

 

02/08/2014 Pana

 

Bujumbura, Burundi - La Marine burundaise a réceptionné, jeudi, un don matériel composé de 21 moteurs pour vedettes rapides de la part du gouvernement américain pour faciliter les patrouilles sur le lac Tanganyika, apprend-on de source sécuritaire à Bujumbura.

 

Les militaires burundais n’étaient pas jusque-là suffisamment outillés pour faire face aux cas de vol de moteurs et leurs accessoires, de téléphones portables et d’argent sur les pêcheurs par des pirates et autres bandes armées organisées qui sévissent fréquemment sur le Lac Tanganyika.

 

Selon le ministre burundais de la Défense nationale et des Anciens combattants, le général Pontien Gaciyubwenge, avec l'appui des Américains, la donne va changer en ce qui concerne la navigation sur le très stratégique Lac Tanganyika qui sert également de transport de personnes et de marchandises aussi bien à l’importation qu’à l’exportation.

 

Le lac sert de frontière naturelle et poreuse par endroits entre le Burundi et ses voisins de la République démocratique du Congo, de la Tanzanie et de la Zambie, sur une superficie de plus de 30.000 kilomètres carrés.

 

Au-delà de cette aide ponctuelle, les Américains apportent encore de l’expertise et des moyens matériels à la force de défense nationale quand il s’agit de se préparer et de déployer des contingents dans des missions de maintien de la paix à l’étranger, comme en Somalie et en République centrafricaine.

Chinese Radar May Pierce F-35 Stealth Armor: Report

 

July 31, 2014 by Brendan McGarry -  defensetech.org

 

Increasingly sophisticated radar in China and Russia may soon be able to pierce the stealth armor on F-22 and F-35 fighter jets, according to a news report.

 

The stealth coating on the U.S.-made fifth-generation fighters shields the aircraft from high-frequency radars operating in the Ku, X and C bands and some of the S band, but not from low-frequency systems utilizing L, UHF and VHF wavelengths, according to an article by Dave Majumdar at USNI News.

 

China and Russia are now working to develop low-frequency radars with more computing power designed to track stealth aircraft with more precision — enough to target them with a missile, according to the report, citing an unnamed former senior U.S. Navy official.

 

“Acquisition and fire control radars are starting to creep down the frequency spectrum,” the official told USNI News. “I don’t see how you long survive in the world of 2020 or 2030 when dealing with these systems if you don’t have the lower frequency coverage.”

 

To be sure, the Defense Department is aware of the increasing sophistication of enemy air defenses, known in military parlance as anti-access, area-denial, or A2-AD, environments.

 

The Pentagon’s latest annual report to Congress on military and security developments in China notes the country is continuing its military build-up and views defense against stealth aircraft and drones as “a growing priority.”

 

The People’s Liberation Army, or PLA, has long sought to control the flow of information in the event of war to thwart data-hungry adversaries such as the U.S. It considers the strategy of “information dominance” a critical form of defense against countries that it views as “information dependent,” according to previous assessments.

 

Perhaps not surprisingly, the People’s Liberation Army Navy, or PLAN, sent an uninvited spy ship, probably the type 815 Dongdiao-class intelligence collection vessel Beijixing (pennant number 851), to this year’s Rim of the Pacific exercise, according to an article by Sam LaGrone of USNI News.

 

China is participating in the event — the world’s largest naval exercise, held off the coast of Hawaii — for the first time this year, with four vessels.

 

The head of U.S. Pacific Command, Adm. Samuel Locklear, this week described the presence of the surveillance ship as “a little odd,” though it “hasn’t created any difficulties in the exercise,” which ends Friday.

Air Transportation: DC-9 Gets Out Of The Navy

 

August 10, 2014: Strategy Page

 

The U.S. Navy recently retired its last C-9B transport aircraft. The C-9s are actually DC-9 airliners converted to serve as 23 C-9A medical evacuation aircraft for the air force and 29 C-9B convertible personnel/cargo aircraft for the navy and marines. There were also three converted to be VC-9C VIP transports for the Department of Defense and two were purchased by Kuwait as C-9Ks. All of these have now been retired except for two C-9Bs still in use by the marines. The C-9 weighed 49-52 tons (depending on type) and could carry up to 16 tons of cargo or over 120 passengers. The C-9 entered service in the 1960s and 70s although the navy bought twelve second hand DC-9s in the 1980s and converted them to C-9s. 

 

The DC-9 was very popular once it entered service in 1965. Nearly a thousand were built before production ceased in 1982. The DC-9 continued in production as the MD-80, MD-90 and Boeing 717 until 2006. Over 2,400 of all models were produced and hundreds are still in service. But the navy wanted a replaced for the C-9 and in 2001 the navy received its first C-40A transport. The navy has received a dozen C-40s so far. The C-40 is actually a Boeing 737-700C commercial aircraft. The plane entered service in 2001, and 19 have been built, eleven for the navy. The 78 ton aircraft carry 121 passengers, or eight cargo pallets (or a combination of both, usually three pallets and 70 passengers.) Max range is 5,600 kilometers. It normally carries a crew of five (two pilots, one crew chief, one loadmaster and one transport safety specialist, which is what the navy calls a flight attendant). When carrying just cargo, the flight attendant does not come along.

 

The C-40A is operated by navy reservists, and is mainly used to rush needed parts or personnel to where the fleet needs them. The C-40s also replaced the C-137 (a military version of the 148 ton B-707.) The navy is also using the 737 as the basis for its new P-8 maritime reconnaissance aircraft. The C-40 experience had a lot to do with the P-8 decision.

Future Carrier to Feature More Prebuilt Parts

 

August 6, 2014 by Kris Osborn -  defensetech.org

 

The Navy and Newport News Shipbuilding are working on new shipbuilding methods and making early progress with initial construction of the second, next-generation Ford-class aircraft carrier slated to enter service in March 2023 — the John F. Kennedy, or CVN 79.

 

The construction strategy for the Kennedy, which is thus far only 6 percent built, is using a handful of techniques intended to lower costs and call upon lessons learned from the building of the first Ford-class carrier in recent years, the USS Gerald R. Ford. The Ford was christened in November, is now undergoing additional testing and slated to enter service in 2016.

Les nouvelles frégates légères de l’US Navy, les Littoral Combat Ships, seraient trop lourdes
 
 

Quatre des 6 navires faisant parti d’une nouvelle classe de bâtiments en cours de développement pour l’US Navy, sont trop lourds. Cela affecte certaines de leurs performances, selon un audit publié récemment.

Un rapport rédigé par le Government Accountability Office indique que l’USS Freedom ne peut atteindre sa vitesse maximale de 40 nœuds ; et il n’est pas parvenu à respecter son autonomie spécifiée de 3.500 nautiques à 14 nœuds, selon le rapport, qui attribue ce problème à une « augmentation excessive du poids ».

Le navire tête de série n’atteint que la vitesse de 39,5 nœuds — contre les 40 exigés — et qu’il déplace un poids qui « dans certaines conditions météo ou après avoir subi certains dégâts, pourrait entraîner des défaillances, » selon le rapport.

Les LCS étaient supposés être des navires rapides pouvant accomplir un certain nombre de missions. Mais le poids a affecté ses performances dans certains domaines. Cela pourrait aussi être un facteur limitant pour de futures évolutions des navires ou des équipements, explique le rapport.

L’USS Freedom est trop lourd de 24 tonnes.

Selon le rapport, l’US Navy envisage déjà de réaliser des modifications qui pourraient encore augmenter le poids des LCS : augmenter la taille des équipages et changer de système de missiles.

Pour l’US Navy, les éventuels changements présentent peu de risques et ne devraient pas modifier les performances des LCS.

US Confirms Fresh Airstrikes Against Militants Near Arbil

 

Aug. 10, 2014 – Defense news (AFP)

 

WASHINGTON — United States warplanes and drones pummeled Islamic State militants near Arbil in a fresh wave of airstrikes on Sunday, destroying armed trucks and a mortar position, the US military confirmed.

 

US Central Command (CENTCOM) said five strikes had been carried out from 0615 GMT, when aircraft struck and destroyed an armed vehicle firing on Kurdish forces outside Arbil in northern Iraq.

 

Shortly after the strike, US forces located another IS armed truck moving away from the area and destroyed it, CENTCOM said.

 

In a further attack at around 0740 GMT, US aircraft struck and destroyed an IS mortar position and damaged a nearby truck.

 

Two more IS armed vehicles were hit in additional strikes before all US aircraft exited the area safely, the military said.

 

The attacks mark the third day of airstrikes launched by the United States in an effort to halt the advance of Islamic militants who are threatening Arbil, the capital of the Iraqi Kurdish region.

 

President Barack Obama authorized the strikes on Thursday to help break the siege of Mount Sinjar, where thousands of civilian refugees from the Yazidi religious minority had been trapped.

 

A Yazidi lawmaker said Sunday at least 20,000 had managed to flee the siege with the help of Kurdish troops and cross into Kurdistan via Syria.

L'étau ukrainien autour de Donetsk se resserre

 

10.08.2014 Romandie.com (ats)

 

L'armée ukrainienne a pilonné Donetsk dimanche pour, dit-elle, "resserrer l'étau" autour de la ville, fief des séparatistes prorusses. Une maternité a été touchée. La veille, les Occidentaux ont mis en garde la Russie contre toute mission humanitaire, qui équivaudrait à une intervention.

L'armée ukrainienne a annoncé avoir tiré contre les bases rebelles en leur infligeant "de lourdes pertes". Trois soldats ont été tués et 27 blessés en 24 heures, a annoncé le porte-parole militaire Andriï Lyssenko.

Il a également fait état de "combats acharnés" à Krasny Loutch, ville de 120'000 habitants située à 65 km au nord-ouest de Lougansk. Le contrôle de cette Krasny Loutch permettrait, selon Kiev, de bloquer l'acheminement d'aide aux séparatistes de Donetsk depuis la Russie.

 

Solution humanitaire russe

 

La veille, le "Premier ministre" séparatiste Alexandre Zakhatchenko a reconnu que Donetsk était "encerclé" et au bord d'une "catastrophe humanitaire". Il s'est dit prêt à un cessez-le-feu si les forces ukrainiennes interrompent leur offensive.

Face à cette situation qui se dégrade pour les civils, dont 300'000 ont déjà fui vers la Russie et les autres régions de l'Ukraine, Moscou a proposé de mener une mission humanitaire dans l'est de l'Ukraine pour protéger la population russophone.

 

Crainte d'intervention

 

Mais le président américain Barack Obama, le Premier ministre britannique David Cameron et la chancelière allemande Angela Merkel ont tous estimé que toute incursion russe en Ukraine, même sous des prétextes humanitaires, serait "injustifiée, illégale et inacceptable". Ils craignent une intervention russe sous couvert d'une mission humanitaire.

Selon l'OTAN, le nombre de soldats russes postés près de la frontière ukrainienne est passé en trois semaines de 12'000 à 20'000 hommes. Le secrétaire général de l'Alliance atlantique, Anders Fogh Rasmussen a estimé jeudi que la liberté de l'Ukraine et son avenir étaient "menacées". Il a sommé la Russie de retirer son armée.

Irak: les Etats-Unis ont poursuivi leurs frappes aériennes dimanche

 

10 août 2014 Romandie.com (AFP)

 

Washington - Les forces américaines ont poursuivi dimanche leurs frappes aériennes dans le nord de l'Irak pour aider les forces kurdes et protéger les personnels américains, a annoncé le Pentagone.

 

Les forces militaires américaines ont continué à attaquer les terroristes de l'Etat islamique (EI) en Irak aujourd'hui, conduisant avec succès de multiples frappes aériennes, tant avec des avions qu'avec des drones, pour défendre les forces kurdes près d'Irbil, où des personnels et des citoyens américains sont stationnés, a précisé dans un communiqué le Central Command, qui gère la région Moyen-Orient.

 

Celui-ci a précisé que plusieurs camions armés et une position de mortier avaient notamment été détruits. Tous les appareils américains ont pu quitter les zones de combat sans dommages.

 

C'est la troisième journée consécutive durant laquelle les Etats-Unis mènent des frappes aériennes contre les jihadistes de l'EI.

 

La progression des jihadistes a jeté sur les routes des dizaines de milliers de personnes, en particulier des chrétiens et de nombreux membres de la minorité kurdophone des Yazidis.

 

Des vivres et du matériel à destination des milliers de citoyens menacés par les jihadistes sur le Mont Sinjar ont aussi été largués par avion.

 

Barack Obama n'avait avancé samedi aucun calendrier sur la durée des frappes aériennes américaines en Irak pour enrayer l'avancée des jihadistes, soulignant qu'il faudrait du temps pour que le gouvernement irakien soit en mesure de faire face lui-même à la menace.

Aug 1, 2014 defense-update.com

 

Earlier in July 2014 the Marine Corps Warfighting Lab (MCWL) has tested two new robotic systems during the Advanced Warfighting Experiment which took place as part of the Rim of the Pacific (RIMPAC) 2014 exercise in Hawaii. The systems included the the LS3 Legged Squad Support System and GUSS - Ground Unmanned Support System.

 

One of the robots included the Legged Squad Support System (LS3) which joined a Marine company on rugged terrain, offloading part of their supplies. The other was the Ground Unmanned Support System (GUSS), an autonomous Jeep size vehicle, that could deliver relatively heavy loads to the forward units, without putting drivers and security teams at risk. Both vehicles are part of MCWL’s thrust to lighten the load carried by the Marine squad; the two vehicles are designed to carry out such mission in different terrain. In addition, the GUSS can also be operated for casualty evacuation missions.

Naval Power Bolsters U.S. Airstrikes in Iraq

 

August 8, 2014 by Kris Osborn - defensetech.org

 

Navy assets deployed to the Persian Gulf are responsible for providing the advanced fire power and weaponry used in targeted U.S. military strikes August 8 against Islamic State of Iraq and the Levant artillery positions, Pentagon officials told Military​.com.

Two F/A-18 aircraft dropped 500-pound laser-guided bombs on a mobile artillery piece near Irbil, Pentagon spokesman Rear Adm. John Kirby said in a statement. ISIL was using this artillery to shell Kurdish forces defending Irbil where U.S. personnel are located, he said.

The fighter jets were launched from the aircraft carrier USS George H.W. Bush, which has been forward deployed in the region for months.

Aug 3, 2014 defense-update.com

 

The U.S. Army is looking at helmet prototypes with optional parts to protect the face and jaw from various threats, including blast waves.

 

The US Army recently concluded a study evaluating the safety and survivability applications of different headgear carried by the modern soldier. The Natick Soldier Research, Development, and Engineering Center conducted the study called ‘Helmet Electronics and Display system — Upgradeable Protection’ (HEaDS-UP) as part of a multi-year effort to develop integrated headgear technologies for the Army and Marines. The program, managed by Mr. Donald R. Lee II, recommend potential upgrades for current helmets, improving the safety and integration with headgear, communications displays. Two modular headgear concept designs emerged from the process include improved eye and face protection which include the mandible and visor. Both provide fragmentation protection for the face. According to Don Lee, project engineer in the Headgear Thrust Area at Natick, the new new headgear parts will be provided as attachments parts can be added or removed in seconds. “Being able to don that (mandible and visor) protection when needed or being able to remove it when not needed is the big ‘wow’ factor,” he added. Other aspects of the program are evaluating improved ballistic materials, non-ballistic impact liner materials and designs, see-through and projected heads-up display technologies,improved hearing protection and communications.

E-11A - Battlefield Airborne Communications Node (BACN)

E-11A - Battlefield Airborne Communications Node (BACN)

 

8 August 2014 airforce-technology.com

 

Northrop Grumman has been awarded a contract to continue the operation and support of the US Air Force's (USAF) battlefield airborne communications node (BACN) system.

 

Under the $89.7m contract's terms, the company will extend operational support of the BACN payloads in support of overseas contingency missions until June 2015.

 

Equipped with an airborne executive processor (AEP), BACN is a forward-deployed network-centric enterprise information server, developed to enable data sharing between different battlefield communications systems using a suite of computers and radio systems.

 

The high-altitude BACN payloads are integrated onto four E-11A Bombardier Global Express BD-700 aircraft and three EQ-4B Block 20 Global Hawk unmanned aerial vehicles deployed in support of Operation Enduring Freedom in Afghanistan.

 

Northrop Grumman Information Systems communications division vice-president and general manager Jeannie Hilger said: "BACN is making such a tremendous difference for our warfighters that it is regarded as indispensable for mission success.

 

"The amount of positive feedback BACN receives from our warfighters is a testament to the critical support BACN currently provides and an inspiration to continuously enhance the system's capabilities."

 

The BACN also provides an advanced airborne communications capability to commanders and troops, as well as enhancing situational awareness and extending voice communications.

 

Northrop expects BACN to serves as a persistent high-altitude gateway in the joint aerial layer network (JALN) to offer secure communications to disadvantaged soldiers and network connectivity across the theatre.

 

The JALN would be designed to expand on existing communications networks and capabilities and links ground, space and airborne military assets.

 

Northrop serves as prime contractor for the EQ-4B Global Hawk UAV and the development, fielding and maintenance of the BACN system, and received the first BACN contract from the US Air Force Electronic Systems Center in April 2005.

OWL ammo will be all tracers but invisible to the enemy

The ultimate goal is to replace the tracer rounds with the OWL rounds and, potentially, put OWL on the back of every ball round. Since it is anticipated that OWL will be applied to all ball rounds, effectively making ball rounds trace without the need of a cavity, they will all have the same trajectory. And since the shooter can see the exact trajectory of where their round is heading, they can quickly make adjustments to get on target faster. Photo: US Army by Reece Lodder.

 

Aug 6, 2014 defense-update.com

 

Engineers at Picatinny Arsenal are researching a way to develop a tracer round that will be visible to the shooter in daylight and night time but would remain invisible to the enemy at night.

 

Engineers at Picatinny Arsenal are researching a way to develop a tracer round that will be visible to the shooter in daylight and night time but would remain invisible to the enemy at night.

 

Tracer rounds, which are usually loaded as every fifth round in machine gun belts, provide essential information to Soldiers firing at an enemy target by creating a line-of-sight that allows them to track the trajectory of their bullets and adjust their aim. However, the pyrotechnic streak they emit also gives away the shooter’s location by allowing the enemy to follow the line of pyrotechnic back to the shooter.
