Finmeccanica – Selex ES has been awarded a contract by prime contractor Lockheed Martin to supply 165 advanced targeting lasers for the F-35 Lightning II’s Electro-Optical Targeting System (EOTS). The contract forms part of the Low-Rate Initial Production (LRIP) programme phase.

 

The laser, integrated into the EOTS, allows fighter aircraft crews to perform precision ranging and targeting functions. The award follows on from existing orders for lasers for the F-35 programme.

 

Selex ES has developed a strong relationship with Lockheed Martin, successfully delivering tactical lasers on the F-35 EOTS, the Apache helicopter’s targeting and pilotage system, M-TADS/PNVS, and the Sniper Advanced Targeting Pod.

 

This latest order for the F-35 EOTS programme is critical to sustaining and strengthening this relationship going forward and further expands Selex ES’s highly successful lasers business in Edinburgh.

 

Selex ES is also working closely with Lockheed Martin to meet the aggressive cost reduction challenges of the F-35 programme, whilst at the same time enhancing the laser product. F-35 production is expected to ramp to full rate in 2018 with deliveries forecasted for the next 30 years of more than 3,000 aircraft.

 

The Selex ES laser business has been hugely successful in exporting the products generated by the company’s world-class laser development and manufacturing capabilities. In addition to a number of contracts with US prime contractors, advanced ground-based laser systems were also sold to customers in Europe and the Middle East in 2014.

Recent 'operational test' aboard USS 'Wasp' was no such thing

 

The Marine Corps triumphantly declared its variant of the F-35 combat ready in late July. In the public relations build-up, the recent demonstration of its performance on the USS Wasp was heralded as a rebuttal to the program’s critics.

But a complete copy of a recent memo from the Director of Operational Test and Evaluation (DOT&E) — obtained by the Project On Government Oversight through the Freedom of Information Act — reveals that a number of maintenance and reliability problems “are likely to present significant near-term challenges for the Marine Corps.”

The Marine Corps named this demonstration “Operational Test One,” but it turns out it wasn’t actually an operational test, “in either a formal or an informal sense of the term.” To count as an operational test, conditions should closely match realistic combat conditions.

But DOT&E found the demonstration “did not — and could not — demonstrate that Block 2B F-35B is operationally effective or suitable for use in any type of limited combat operation, or that it was ready for real-world operational deployments, given the way the event was structured.”

The Air Force will give an update next week at the annual Air and Space Conference on its two most needed yet controversial aircraft programs — the F-35 Joint Strike Fighter and the KC-46 Pegasus refueling tanker.

Both projects have recently come under fire from Congress – again. In addition to cost overruns on the $400 billion F-35 program, the fighter’s ability to perform close air support has come into question compared to the aging A-10 Thunderbolt.

The KC-46, developed by Boeing from its 767 series jetliner, has also been hit by cost overruns and questions about Boeing’s ability to meet a deadline to have the aircraft on the ramp and ready for missions by August 2017.

In an Aug. 31 letter to Defense Secretary Ashton Carter, Sen. John McCain, R-Arizona, chairman of the Senate Armed Services Committee, wrote that “I am concerned that the recent problems with the tanker modernization program could prevent the Department of Defense from delivering this critical capability to our warfighters as promised and on schedule.”

The lineup for the Air Force Association’s Air and Space Conference and Technology Exposition at National Harbor, Maryland, on Tuesday includes a panel on the F-35 and the KC-46 led by the main officers in charge of getting both programs back on track – Lt. Gen. Christopher Bogdan for the F-35, and Brig. Gen. Duke Richardson for the KC-46.

Le premier F-35 "Made in Italy" a réussi son premier vol

 

07/09/2015 par Michel Cabirol – LaTribune.fr

 

Le premier avion de combat F-35 assemblé par Finmeccanica en Italie a réussi son premier vol sur la base aérienne de Carmeri, près de Novare.

 

Le premier avion de combat F-35 assemblé en Italie par le groupe italien Finmeccanica, et plus précisément par sa filiale Alenia Aermacchi, a réussi son premier vol sur la base aérienne de Carmeri, près de Novare, a annoncé le groupe italien dans un communiqué publié ce lundi. Le F-35 est un avion de combat furtif multi-rôle de nouvelle génération développé et produit par l'avionneur Lockheed Martin dans le cadre du programme international Joint Strike Fighter. Le F-35 est aussi le programme d'armement le plus cher de l'histoire américaine, avec un coût explosant à 390 milliards de dollars, sans compter quelque sept ans de retard.

"Le succès du premier vol témoigne de la capacité de Finmeccanica à respecter ses engagements de production dans un programme très ambitieux dans le domaine industriel et technologique", a expliqué le groupe aérospatial italien dans son communiqué.

 

L'Italie à bord du F-35

Après sa participation dans la phase de conception avec des équipes intégrées au sein de  Lockheed Martin, Finmeccanica, à travers Alenia Aermacchi, est l'industriel italien leader parmi plus de 25 entreprises transalpines travaillant sur le F-35. Le groupe italien est notamment responsable de l'assemblage des avions de combat pour le compte de l'armée de l'air italienne et pour une partie des appareils destinés à l'armée de l'air néerlandaise.

En outre, le site Cameri fabrique également les composants des ailes du F-35 en plus de la ligne principale gérée directement par Lockheed Martin. Enfin, Cameri a été choisi comme le centre de soutien logistique de l'avion de combat en Europe. Par ailleurs, Finmeccanica est aussi impliqué dans la production de certains des composants électroniques de l'avion par Selex ES.

 

Le F-35 surclasse-t-il vraiment le F-16?

En juillet, l'armée de l'air américaine a souligné que le tout nouveau et très coûteux avion de combat F-35 surclassait bien au combat le robuste et éprouvé F-16, malgré un témoignage de pilote très critique sur les capacités comparées des deux avions. "Il y a eu de nombreuses occasions ou des groupes de F-35 ont engagé des groupes de F-16 en simulation de combat, et les F-35 ont gagné chacune de ces rencontres, grâce à leurs capteurs, leurs armements et leur technologie furtive", a précisé dans un communiqué l'armée de l'air (US Air Force).

Pourtant le site américain "War is Boring" a publié cette semaine le compte-rendu sévère d'un pilote de F-35 après un exercice de combat rapproché contre un F-16 en janvier en Californie. Les deux avions se sont livrés à une série de manœuvres brutales pour tenter d'abattre au canon leur adversaire, mais le F-35 a constamment manqué "d'énergie" pour réaliser ces manœuvres, perdant ainsi face au F-16, selon le compte-rendu. L'armée de l'air n'a pas démenti le compte-rendu du pilote, mais a souligné que le combat rapproché ne figurait pas au programme théorique de cet avion furtif multitâches.

 

Quelles missions pour le F-35?

La technologie du F-35 "est destinée à engager, viser et abattre l'ennemi depuis de longues distances, pas nécessairement en situation de combat visuel", a souligné l'US Air Force. "Les tests opérationnels et de développement continuent. Il est trop tôt pour tirer des conclusions finales sur la capacité à manœuvrer l'appareil", a également souligné le général Jeffrey Harrigian, chargé de l'intégration du F-35 au sein de l'US Air Force.

Le F-35 n'est pas encore en service dans les forces américaines. Les Marines devraient être la première force américaine à le déclarer opérationnel, peut-être dès cet été. Le F-16 avait été développé dans les années 70 par General Dynamics, racheté depuis par Lockheed Martin, qui a développé le F-35.

F-35 Gen III Helmet Mounted Display System (HMDS) - Rockwell Collins

F-35 Gen III Helmet Mounted Display System (HMDS) - Rockwell Collins

 

29 juil 2015 par Morgan - ubergizmo.com

 

Quand on achète un casque de moto plusieurs centaines d'euros, on est en droit d'attendre une certaine qualité, et surtout un bon niveau de sécurité. Et quand on achète un casque à 400 000$ ? On pourrait s'attendre à pouvoir voir à travers les murs, non ? Précisément !

 

Ce casque à 400 000$ (360 000€) minimum, c’est le F-35 Gen III Helmet Mounted Display System (HMDS), conçu tout spécialement pour fonctionner avec l’avion de chasse F-35 Lightning II. C’est Rockwell Collins qui fut chargé de la conception de ce casque. Équipé, comme son nom l’indique, d’un système d’affichage tête haute permettant au pilote d’avoir des informations critiques – altitude, vitesse du vent, cible, avertissements divers, etc – toujours à portée de vue, il permet aussi de voir à l’extérieur comme s’il n’y avait pas la carlingue…

Les trois versions différentes du F-35 - photo  Lockheed Martin

Les trois versions différentes du F-35 - photo Lockheed Martin

 

17 juillet 2015 –Tristan Geoffroy

 

Le successeur du F-16 Fighting Falcon semble se diriger tout droit vers un mur. Est-il trop tard pour éviter de s’embourber dans ce gouffre financier?

 

Depuis ma tendre enfance, j’ai toujours affectionné les avions, avec comme rêve secret, de pouvoir un jour les piloter. Aujourd’hui, c’est toujours les yeux pleins d’émerveillement que je regarde les derniers modèles de chasseurs évoluer dans le ciel dans des manœuvres qui étaient jusqu’à présent impossibles à réaliser.

Malheureusement, une ombre gigantesque est en train d’obscurcir ce beau tableau, celui d’un projet gargantuesque qui aura peut-être raison de certaines compagnies américaines, voire même de notre budget, le F-35.

Depuis les premières évolutions aériennes du Lockheed Martin F-35 Lightning II, les problèmes n’ont cessé de s’accumuler à un rythme alarmant. On pourrait comparer l’évolution du programme F-35 à l’œuvre de plusieurs docteurs Frankenstein qui ne se seraient jamais consultés, en travaillant cependant sur le même corps.

Un F-16 en vol avec un F-35. (Archives/Lockheed Martin)

Un F-16 en vol avec un F-35. (Archives/Lockheed Martin)

 

par - 45eNord.ca

 

Un rapport d’un pilote de F-35 de Lockheed Martin qui a fuité sur Internet démontrerait que l’avion de cinquième génération serait dépassé… par l’avion qu’il est supposé remplacé!

 

Le rapport est basé sur une mission de vol qui a eu lieu le 14 janvier dernier à la base d’Edwards, en Californie.

La première observation dans le rapport est que «la caractéristique la plus notable du F-35A (le modèle que souhaite acheter le Canada) dans un engagement visuel, était son manque d’énergie lors de manœuvres. Le pilote note également que le F-35A dispose d’une aile plus petite que le F-15E, un poids semblable, mais 15.000 livres de moins en poussée.

Le F-35 a une limite d’angle d’attaque plus élevé que le F-16, ce qui devrait normalement être un avantage, mais une combinaison de facteurs, incluant un taux de tangage et une énergie lors de manœuvres inférieurs, ce qui le rend moins utile. Il a fallu également trop de temps pour que le F-35 atteigne un angle élevé d’attaque.

Dans ce rapport (voir à la fin de l’article), l’énergie lors de manœuvres est inférieure, le taux de tangage est limité et la qualité de vol n’est «pas intuitive ou favorable» dans une partie importante du combat aérien, ce qui a permis au F-16 de prendre l’avantage tactique. Un autre inconvénient est que le grand casque et la conception de la canopée de l’appareil limitent la vue arrière du pilote.

Dans un cas, tant la logique anti-patinage et le taux tangage lent signifient que le F-35 ne pouvait pas échapper à une attaque armée par le F-16. «Aucune défense armé n’a été possible», indique le rapport. Lors d’une manœuvre d’évasion standard, l’appareil s’est enlisé par la vitesse de tangage, de sorte que «le résultat était une manœuvre qui était facile à suivre».

 

 

Dans les faits, aucun des 17 engagements du F-35A contre sa cible du jour n’aura été concluant et le pilote n’aura pu à aucun moment se mettre en position d’avantage pour engager ses munitions.

Visiblement piqués au vif, Lockheed Martin et le Bureau du programme JSF confirment que le document est authentique, mais disent que «l’interprétation des résultats des scénarios pourrait être trompeuse». Selon le major-général Jeffrey Harrigian, directeur du bureau de l’intégration du F-35 de l’US Air Force, il est «trop tôt» pour juger de la manœuvrabilité du F-35. Plusieurs observateurs s’étonnent cependant que, pour un appareil en développement depuis 1996, la manœuvrabilité ne soit pas déjà un problème réglé!

Bien que le F-35 est conçu principalement pour des attaques de type air-sol plutôt que air-air, les pilotes de Lockheed Martin et de l’US Air Force indiquent qu’il y a encore une certaine marge de manœuvre pour une maniabilité supplémentaire.

Dans un communiqué, Lockheed Martin précise que le F-35 ayant réalisé les essais n’était pas encore équipé de toutes les technologies qui lui auraient permis de prendre le dessus sur son adversaire. Il n’était pas équipé de tous les senseurs, ni de son revêtement spécial qui, en condition opérationnelle l’aurait rendu virtuellement invisible aux radars, ni encore des munitions et du viseur de casque qui aurait permis au pilote de désigner et de tirer sur sa cible sans manœuvrer l’avion.

Ne parlons même pas de la soute du F-35 qui ne permet d’emporter que quatre missiles air-air – deux s’il s’agit de missiles air-sol.

Pour Lockheed cependant, «il y a eu de nombreuses occasions où une formation de quatre F-35 ont engagé une formation de quatre F-16 dans des scénarios de combat simulés et les F-35 ont remporté chacune de ces rencontres en raison de leurs capteurs, des armes et de la technologie furtive».

Si c’est juste une question de capteurs, d’armes et de revêtement spécial…

Le nouveau chasseur américain F-35 est-il vraiment mauvais?

 

02-07-2015 Par Vincent Lamigeon - Challenges

 

L'avion de combat de Lockheed Martin n’a pas réussi à battre un vieux F-16 lors d’un exercice de l’US Air Force. Un nouveau coup dur après ses énormes retards et surcoûts de développement.

 

Le chasseur F-35, programme d’armement le plus cher du monde avec 400 milliards de dollars investis, sera-t-il aussi le plus catastrophique? Une fuite sur le site spécialisé War is Boring vient en tout cas jeter le doute sur les performances du futur appareil de l’US Air Force, de l’US Navy, des Marines et d’une dizaine d’autres pays clients (Royaume-Uni, Pays-Bas, Italie, Australie, Japon, Israël…). Selon le compte-rendu d’un pilote de F-35 après un exercice de combat rapproché contre un F-16 en janvier en Californie, dévoilé par le site,  l’appareil s’est montré incapable de dominer son adversaire, manquant constamment "d'énergie" pour réaliser les manœuvres nécessaires.

 

Manque d'"énergie"

Le combat s’annonçait pourtant inégal. Le F-35 en question, un F-35A monoplace, était opposé à un F-16D Block 40 biplace, soit une version datant de la fin des années 80. Mieux, le F-35 volait sans armement ni réservoirs de carburant, à l’inverse du F-16, chargé de deux réservoirs, et non handicapé du point de vue aérodynamique. Pourtant, le F-16 a fait mieux que résister, raconte le pilote. "Même avec la configuration limitée du F-16, le F-35A a gardé un désavantage d’énergie sur tous les engagements", écrit-il selon War is Boring.

En gros, le F-35 a fait montre d’inquiétantes faiblesses aérodynamiques. Il s’est avéré trop lent pour toucher le F-16 au canon de 25 mm. Il s’est même montré incapable de manœuvrer assez rapidement pour éviter les tirs de son adversaire. Pire, selon le pilote, le casque de vision à 360 degrés de l’appareil ne permet pas de voir tout ce qu'il se passe autour de soi. "Le casque était trop grand par rapport à l'espace disponible pour voir derrière l'avion", écrit le pilote. Fâcheux quand l’avion est en situation de "dogfight", même si ces duels aériens façon Top Gun sont devenus rarissimes.

 

"Moins bon que le F-15"

Le pilote affirme même que le F-35 est "substantiellement inférieur" au vieux F-15 qu’il pilotait il y a quelques années. Conclusion impitoyable de l’auteur de l’article, David Axe : "Pendant quelques décennies, les Américains et les aviateurs alliés vont combattre dans un chasseur inférieur, qui pourrait les envoyer à la mort… et coûter aux Etats-Unis le contrôle de l’espace aérien."

Chez Lockheed Martin et au Pentagone, on sort les parapluies. Un communiqué du constructeur américain assurait le 1er juillet que "l’article ne raconte pas toute l’histoire", soulignant que le F-35 impliqué (l’AF-2) est destiné aux "tests scientifiques" et aux tests de "qualités en vol" de l’avion. "Il n’est pas équipé de nombre de fonctions intégrées aux F-35 produits actuellement, appareils de 5ème génération", indique Lockheed Martin.  

 

159 millions de dollars pièce

Même l’US Air Force s’est fendue d’un communiqué, jurant qu’"il y a eu de nombreuses occasions ou des groupes de F-35 ont engagé des groupes de F-16 en simulation de combat, et les F-35 ont gagné chacune de ces rencontres, grâce à leurs capteurs, leurs armements et leur technologie furtive". Mais l’industriel et les militaires américains se sont bien gardés de démentir les conclusions du pilote cité par War is Boring.

Pour eux, l’appareil n’est clairement pas destiné au dogfight : le F-35 "est destiné à engager, viser et abattre l'ennemi depuis de longues distances, pas nécessairement en situation de combat visuel", souligne l'US Air Force. Une faiblesse quand même fâcheuse pour un avion à 159 millions de dollars pièce, selon les derniers chiffres du GAO, l’équivalent américain de la Cour des comptes

24 Jun 2015 By: Beth Stevenson – FG

 

The UK and USA have carried out the first short take-off test of the Lockheed Martin F-35B Lightning II during a ground-based test at Patuxent River Naval Air Station in Maryland, USA on 19 June.

 

This marks the start of the first phase of testing to certify the UK’s short take-off and vertical landing F-35B as capable of take off and landing from an aircraft carrier. The work is being controlled by the F-35 Pax River Integrated Test Force (ITF), assigned to the Air Test and Evaluation Sqn 23.

 

Test aircraft BF-04 took off on a ski-jump, demonstrating the F-35B’s ability to integrate into the UK’s future operations. The UK has selected the ski-jump approach as opposed to the catapult and arresting gear approach favoured by the USA in its carrier operations.

 

The UK’s new carriers – HMS Queen Elizabeth and HMS Prince of Wales – are shorter and contain an upward slope ramp at the bow, curved to allow for the F-35B to launch upward and forward at the same time. This allows the aircraft to take off with more weight and at a lower speed than a horizontal launch permits, the UK Ministry of Defence says.

 

"Friday’s F-35B ski-jump was a great success for the joint ski-jump team,” says Peter Wilson, BAE Systems test pilot and ski-jump project lead.

 

“As expected, aircraft BF-04 performed well and I can’t wait until we’re conducting F35 ski-jumps from the deck of the Queen Elizabeth carrier. Until then, the de-risking that we’re able to achieve now during phase I of our ski jump testing will equip us with valuable data we’ll use to fuel our phase II efforts.”

 

This follows a test on 12 June during which Royal Air Force test pilot Sqn Ldr Andy Edgell released two inert Raytheon Paveway IV precision-guided bombs from F-35B test aircraft BF-03.

 

The 500lb dual mode weapons were dropped over the Atlantic Test Ranges at Pax River, marking the first weapons separation test of the Paveway by the ITF. The passive bombs safely separated from an internal weapons bay within the F-35B, Lockheed Martin says, and maintained the stealth characteristics of the aircraft throughout

Une nouvelle commande de F-35

 

08/06/2015  par Emmanuel Huberdeau – Air & Cosmos

 

Le département de la défense américain a annoncé l'attribution à Lockheed Martin d'un contrat de plus de 920M$ pour la production de 94 F-35.

 

Ce contrat prévoit la commande de 44 F-35A (Version conventionnelle) pour l'US Air Force, 14 F-35B (Version à décollage court et atterrissage vertical) pour les Marines et de 2 F-35C (Version embarquée) pour l'US Navy.

 

L'Italie réceptionnera deux F-35A et autant de F-35B. La Grande Bretagne bénéficiera également de deux F-35B. Ce contrat prévoit la fourniture de 8 F-35A à l'Australie, 2 pour la Turquie, 6 pour la Norvège et 16 autres appareils pour d'autres clients non dévoilés.

 

Le Pentagone ne précise pas à quel lot LRIP (Production de pré série) ces appareils appartiendront. Fin 2014 il était prévu qu'un total de 57 F-35 soient commandés au titre de l'année fiscale 2015 et 97 appareils au titre de l'année fiscale 2016.

A group of Royal Navy and Royal Air Force personnel were at sea onboard USS WASP, joining American colleagues in the latest F-35B Lightning II fast jet trials.

Lightning II is a STOVL aircraft: Short Take Off Vertical Landing. It will place the UK at the forefront of fighter technology, giving the RAF a true multi-role all weather, day and night capability, able to operate from well-established land bases, deployed locations or the Royal Navy's Queen Elizabeth Class Aircraft Carriers.

The Royal Navy’s vision for tactical integration of the F-35B into their current arsenal is similar to the Marine Corps’ plan to integrate the F-35 with legacy aircraft, such as the AV-8B Harrier and the F/A-18 Hornet, and gradually phase out legacy aircraft over the coming decades.

Washington DC - The overall cost of the Lockheed Martin F-35 Lightning II programme will come in at about $7.5 billion less than previously expected, according to the 2015 selected acquisition report (SAR).

Released on 18 March, the report indicates that research, development, test and evaluation cost remains unchanged at $54.9 billion, but that procurement costs declined by $7.7 billion, to $331 billion. The F-35 Joint Program Office (JPO) says the reduction was primarily due to decreased labour costs.

While the SAR reports that the operating and support (O&S) costs of the F-35 over its service life remain nearly $1 trillion – the cost assessment programme evaluation that authors the SAR does not adjust O&S figures until a major milestone is reached – the JPO claims its revised cost estimate for this metric showed a $57.8 billion reduction from 2014, bringing the overall figure to $859 billion.

Lockheed's F-35 programme general manager, Lorraine Martin, says the company has reduced O&S costs for the F-35 by $60 billion in the past year alone.

Lockheed Martin est en train de développer un pod de cyber-attaque pour le F-35 Lightning II dans le cadre d’une intégration d’armes cinétiques, a déclaré le responsable exécutif du programme le 17 mars.

 

« L’industrie développe un pod qui n’altèrera pas la signature radar de l’avion », a déclaré le contre-amiral Randy Mahr à la conférence de l’association Precision Strike à Springfield (Virginie). Il a ajouté que ce système offensif était dans la « phase de prototypage » et qu’il n’était pas conçu par Lockheed Martin (tout en refusant de nommer le développeur).

Parallèlement, le contre-amiral Mahr a déclaré que le F-35B à décollage court et atterrissage vertical (STOVL) serait compatible avec la nouvelle bombe Raytheon GBU-53/B SDB II (Small Diameter Bomb Increment).

La soute du F-35B est toutefois limitée et l’emport d’une GBU-53 nécessitera quelques adaptations.

« La SDB II s’adaptera au F-35B », a précisé le contre-amiral Mahr. « Nous devons simplement passer une ligne hydraulique et un faisceau de fils d’un demi-pouce de chaque pour la faire rentrer ».

Il a précisé que la SDB II était encore en développement et ne serait pas prête pour l’intégration avant l’achèvement du F-35 Bloc 4.

20 March 2015 airforce-technology.com

 

Textron Systems Electronic Systems has been awarded a contract to supply advanced, handheld radar simulators for electronic warfare (EW) preflight testing on all variants of the F-35 Lightning II aircraft.

 

The contract was awarded by Lockheed Martin. It requires the company to supply its Model 527 radar signal simulator, which is designed for end-of-runway and walk-around pre-flight testing, to determine the status of installed electronic warfare (EW) radar warning receiver systems.

 

Specifically, the system verifies operational readiness and threat recognition across antennas, transmission lines, radomes, cockpit displays, and controls on operational aircraft through free-space radiation functional testing.

 

Textron Systems Electronic Systems senior vice-president and general manager Steve Mensh said: "The F-35 is one of the world's most advanced tactical aircraft, designed to deliver powerful new capabilities to the warfighter.

 

"Our Model 527 and larger family of pre-flight testers give aircrews the confidence they need in their mission-critical systems, before they even leave the ground."

 

The advanced threat modelling software enables a variety of threat simulations including simple, continuous-wave, pulsed single emitters, and multiplexed radio frequency emitters that can model several threats simultaneously.

 

After the simulations have been developed within the system, soldiers can easily progress through them on the flight line with a thumb switch to verify aircraft operation.

 

The battery-powered system is fully compatible with the company's family of pre-flight confidence testers, such as the joint service electronic combat systems tester and the advanced architecture phase, amplitude and time simulator laboratory electromagnetic environment simulator.

 

Deliveries under the indefinite-delivery / indefinite-quantity (IDIQ) contract are scheduled take place over the next three years.

 

The F-35 is manufactured by Lockheed. It is a fifth-generation multi-role fighter, and is designed to conduct a wide range of ground attack, reconnaissance, and air defence missions with stealth capability.

Australia’s First F-35A Pilot Takes Flight

 

21 March 2015 Pacific Sentinel

 

Australia first F-35A pilot, Squadron Leader Andrew Jackson, yesterday [AEST] took his first flight in an F-35A aircraft at Eglin Air Force Base, Florida, United States.

 

The flight was on the morning of Wednesday 17 March (US CST) in a United States Air Force F-35A aircraft, as the Australian F-35A aircraft are currently located at Luke Air Force Base, in anticipation of the opening of the international pilot training centre in mid 2015. SQNLDR Jackson will continue his intensive training program over the coming months.

 

The F-35A (commonly known as the Joint Strike Fighter) will meet Australia’s future air combat and strike needs, providing a networked force-multiplier effect in terms of situational awareness and combat effectiveness.

 

The F-35A’s combination of stealth, advanced sensors, networking and data fusion capabilities, when integrated with other defence systems, will enable the RAAF to maintain an air combat edge.

 

The first F-35A aircraft will arrive in Australia at the end of 2018 with the first operational squadron to be established by 2020. The F-35A will replace the aging F/A-18A/B Hornets at RAAF Bases Williamtown (NSW) and Tindal (NT).

March 19, 2015 by JOSEPH TREVITHICK – War is boring

 

Eventually, the U.S. Air Force wants to replace the low and slow-flying A-10 Warthog with the fast-moving F-35 stealth fighter. But it’ll take years before the troubled jet fighters are ready for duty. In the meantime, the Air Force still needs a plane for dedicated close air support missions — something the A-10 excels at. So what does the flying branch propose? Not keeping the Warthog. Instead, the Air Force wants to replace the Warthog with a modified F-16 fighter jet — an old concept that failed to live up to expectations decades ago. The F-16s would fill in temporarily until the F-35s can take over. We have a hard time believing it — but yes, this is a serious proposal.

The U.S. Air Force recently revealed that a new (JMMBRU) bomb rack for the F-35 will not work in the bomb bay of the vertical takeoff version (F-35B) of the F-35 until the bomb bay is modified to move a hydraulic line and a bracket. These two items did not interfere with the original bomb racks that were to go into the bomb bay. The JMMBRU is a new development that was not really planned for when F-35 development began. Sort of an “unknown, unknown.” 

 

In late 2014 the air force had successfully tested the new JMMBRU bomb rack for the 225 kg SDB (Small Diameter Bomb) in an F-35A. JMMBRU allows the F-35 to carry eight SDBs internally (instead of four), plus (in a less stealthy configuration) another 16 externally. This makes the F-35 a much more effective bomber, especially since the SDB has been upgraded to glide farther and hit moving targets, as well as still penetrate the ground to destroy bunkers. The new SDB II has three different guidance systems: radar, heat seeker, and homing on laser light bounced off the target. That means no matter what the weather or time of day there is a guidance system that will find the target.

 

A frequent user of JMMBRU will be the vertical takeoff version, which the U.S. Marine Corps needs to provide ground support. The marines are buying 533 F-35Bs and the B version had to be heavily modified internally to handle the vertical takeoff capability. Changes to the bomb bay (including making it a bit smaller) were considered acceptable until the JMMBRU was designed and apparently did not take into account these differences in the F-35B

 

Meanwhile a lot of controversy surrounds the F-35. The U.S. Air Force still expects to get production models of its 31 ton F-35A in late 2016. This is the cheapest version, costing about $159 million each. The U.S. Navy version (the F-35C) will arrive in late 2019 and cost about $264 million each. This version has a stronger landing gear to handle carrier landings and components that are more resistant to corrosion from constant exposure to salt water. The vertical take-off version for the marines, the F-35B, will cost $214 million each. All of these prices are expected to be much higher (20 percent or more) in reality. This is happening despite more and more delays as well as questions about reliability and cost. At the moment the F-35 costs 60 percent more (than the F-16, per flight hour) to operate.

 

The F-35 is armed with an internal 25mm cannon and, before the SDB, four internal air-to-air missiles (or two missiles and two smart bombs) plus four external smart bombs and two missiles. All sensors are carried internally and max weapon load is 6.8 tons. The aircraft is very stealthy when just carrying internal weapons. The more compact (it looks like a missile) SDB was designed with the internal bomb bays of the F-22 and F-35 in mind.

 

Like the F-22 fighter, the F-35 is stealthy and stuffed with a lot of new technology. Most (about 60 percent) of the F-35s built will be used by foreign nations. The rising cost of the F-35 brings with it reluctance to buy as many aircraft as currently planned. The success of smart bombs in Iraq and Afghanistan has also made it clear that fewer aircraft will be needed in the future. In any event, it's likely that F-35s will end up costing close to $200 million each. But with SBDs F-35s become a very potent bomber that can get at well protected targets.

F-35 Lightning II Program Quality Assurance and Corrective Action Evaluation

 

Mar 14, 2015 defense-aerospace.com/

(Source: DoD Inspector General; issued Mar 13, 2015)



Objective
We inspected the F-35 Lightning II Program (F-35 Program) at Lockheed Martin, Fort Worth, Texas, for conformity to the contractually required Aerospace Standard (AS)9100, “Quality Management Systems – Requirements for Aviation, Space and Defense Organizations.”

We also evaluated corrective actions taken in response to nonconformities, findings, and recommendations identified in DoD Inspector General (IG) Report No. DODIG-2013-140, “Quality Assurance Assessment of the F-35 Lightning II Program,” September 30, 2013, to determine whether the actions taken were appropriate.

Findings
The F-35 Program generally conformed to requirements and showed improvement in quality management system performance since our previous evaluation; however, challenges still remain, as evidenced by 57 nonconformities to the AS9100 standard and 4 opportunities for improvement. The Joint Program Office (JPO) did not:

A. ensure the program made sufficient progress toward full compliance with Public Law 108-136, “National Defense Authorization Act for fiscal year 2004,” Section 802, “Quality control in procurement of aviation Critical Safety Items (CSIs) and related services,” and the Joint Service CSI Instruction (SECNAVINST 4140.2), “Management of Aviation Critical Safety Items,”

B. ensure that all system level requirements and capabilities were realized and verified,

C. create an independent quality assurance organization, establish its roles and responsibilities, and ensure it was adequately staffed to perform effective oversight for the F-35 Program,

D. ensure that Lockheed Martin was taking necessary steps to reduce the assembly defect rate in order to meet the full rate production goals,

F. ensure that Lockheed Martin’s software quality management processes were performed sufficiently to prevent software defects, and G. ensure that Lockheed Martin flows down all contractual requirements to its subcontractors, evaluates deliverables for contract compliance, and allows minor non-conformances to be approved only by the proper authority.

In addition, the Defense Contract Management Agency (DCMA) did not:

E. escalate unresolved Corrective Action Requests (CARs) to the next higher level as appropriate and required by its policy, for effective resolution.
 

Recommendations

We recommend that the Joint Program Office:

A.1. ensure that the F-35 CSI Program is compliant with Public Law 108-136, Section 802, “Quality control in procurement of aviation CSIs and related services,” and the Joint Service CSI Instruction, “Management of Aviation Critical Safety Items”;

A.2. conduct periodic CSI Program evaluations of Lockheed Martin and its suppliers to ensure compliance with public law and the Joint Service CSI Instruction;

B.1. clearly define contractual criteria for the acceptance of all future and fielded aircraft to ensure that aircraft capabilities are verified;

B.2 ensure that all 21 system-level requirements that may not be met, in addition to the risks associated with the failure to meet these requirements, are documented, tracked, and mitigated using the established risk management process;

C. realign the quality assurance organization to report directly to the Program Executive Officer, define the organization’s roles and responsibilities, and staff the organization appropriately;

D.1. ensure that Lockheed Martin implements quality improvement initiatives to reduce the assembly defect rate to meet full rate production goals;

D.2. coordinate with DCMA to implement an effective root cause analysis and corrective action process in order to reduce assembly defect rate;

F. work with Lockheed Martin to ensure software quality management systems are improved; metrics should be reported on a periodic basis (for example, monthly) to evaluate process improvement; and

G.1. ensure that all minor non-conformances are evaluated and approved only by DCMA.

 

We recommend that the DCMA:

E.1. review all unresolved CARs and escalate those that meet the criteria established in DCMA policies and instructions,

E.2. assess all CARs that were not properly elevated and assess any impact on the product, and

G.2. ensure that Lockheed Martin flows down the appropriate technical requirements to its subcontractors and receives and evaluates contract deliverables within the required time frames.

 

Management Comments and Our Response

On January 20, 2015, JPO and DCMA provided comments on our findings and recommendations. The Joint Program Office agreed with six recommendations and partially agreed with three recommendations.

JPO partially agreed with the recommendation to track 21 system-level requirements, which it acknowledged will not be met. However, JPO does not consider the 21 system-level requirements as risks and did not agree to track them in its formal risk management process. We disagree with this approach because a final determination of performance has not been made and failure to track the risks in the formal risk management process prevents an identification of the plans necessary for closure.

JPO partially agreed with the recommendation to work with DCMA to implement an effective root cause analysis and corrective action process to reduce assembly defects to meet full-rate production goals. However, JPO stated that no additional changes to corrective action processes were necessary. We disagree with JPO’s response because additional quality initiatives are required to meet full?rate production goals and DCMA’s involvement is necessary to ensure objectives are met. Our recommendation was for JPO to take actions to identify and correct the cause of the program’s inability to reduce defect rates to support full-rate production.

JPO also partially agreed with our recommendation to ensure all minor non-conformances are evaluated and approved only by DCMA. The actions that JPO is planning to meet the intent of the recommendation.

DCMA agreed with all three of our recommendations. The actions that DCMA is planning to take meet the intent of the recommendations.

F-35 Is Not Ready for Prime Time


 

Mar 13, 2015 defense-aerospace.com

(Source: Project On Government Oversight; posted March 12, 2015)

 

DOT&E Report: The F-35 Is Not Ready for IOC and Won't Be Any Time Soon (excerpts)



Inside-the-Beltway wisdom holds that the $1.4 trillion F-35 Joint Strike Fighter (JSF) program is too big to cancel and on the road to recovery. But the latest report from the Defense Department’s Director of Operational Test and Evaluation (DOT&E) provides a litany of reasons that conventional wisdom should be considered politically driven propaganda.

The press has already reported flawed software that hinders the ability of the plane to employ weapons, communicate information, and detect threats; maintenance problems so severe that the F-35 has an “overdependence” on contractor maintainers and “unacceptable workarounds” (behind paywall) and is only able to fly twice a week; and a high-rate, premature production schedule that ignores whether the program has demonstrated essential combat capabilities or proven it’s safe to fly.

All of these problems are increasing costs and risks to the program. Yet rather than slow down production to focus resources on fixing these critical problems, Congress used the year-end continuing resolution omnibus appropriations bill—termed the “cromnibus”—to add 4 additional planes to the 34 Department of Defense (DoD) budgeted for Fiscal Year 2015.

The original FY2016 plan significantly increased the buy to 55, and now the program office is further accelerating its purchase of these troubled planes to buy 57 instead.

At some point, the inherent flaws and escalating costs of a program become so great that even a system with massive political buy-in reaches a tipping point. The problems described in the DOT&E report show that the F-35 has reached a stage where it is now obvious that the never-ending stream of partial fixes, software patches, and ad hoc workarounds are inadequate to deliver combat-worthy, survivable, and readily employable aircraft.

This year’s DOT&E report also demonstrates that in an effort to maintain the political momentum of the F-35, its program office is not beneath misrepresenting critically important characteristics of the system.

In sum, the old problems are not going away, new issues are arising, and some problems may be getting worse.

Below are some of the key issues raised by the DOT&E report.

Cooking the Numbers

The Joint Program Office, led by Air Force Lt. Gen. Chris Bogdan, is re-categorizing failure incidents to make the plane look more reliable than it actually is. This kind of number-cooking has been done in other important areas of the program, such as using gimmicks to lowball acquisition costs and operating costs per flying hour.

Washington DC - Rolls-Royce has opened the first repair and overhaul facility for the Lockheed Martin F-35B's LiftFan system in Indiana, as it consolidates assembly of major components away from the UK.

The $10 million LiftWorks repair facility in Plainfield will serve as an interim logistics hub for F-35Bs operated by the US Marine Corps and the UK. The site could eventually be augmented or replaced by the US government depot system or separate repair and overhaul facilities in the UK or Italy, should either of those governments decide to invest in that capability, says Tom Hartmann, senior vice-president of R-R.

Britain invests in facilities for F-35 aircraft

 

LONDON, Feb. 23 (UPI)

 

Britain says it is building facilities for operation of its future F-35 Lightning II aircraft fleet at a Royal Air Force base in the east of the country.

 

Nearly $462 million is being invested in Eastern England for facilities to handle F-35 Lightning II aircraft, the Ministry of Defense reported. The funding will be directed at RAF Marham, with work planned to begin on infrastructure and facilities by the end of this year. The construction work will create 1000 new jobs directly in the construction phase of the project and an additional 700 jobs in the supply chain, the ministry said.

CANBERRA, Australia, Feb. 27 by Richard Tomkins (UPI)

 

 Australia announced this week a cooperative development deal with Norway for a Joint Strike Missile for F-35s and a strategic alliance with the Airbus Group.

The agreement with the Norwegian government aims to introduce the maritime strike missile by Kongsberg Defense and Aerospace on F-35 Lightening II fighters in the early 2020s.

"Although far apart geographically, Norway and Australia share many of the same challenges," said Norwegian Minister of Defense Ine Eriksen Søreide. "We are both maritime nations on the periphery of our immediate regions, with a large land mass and even larger maritime territories, yet relatively limited populations. This means that we have to maximize the effects of the capabilities that we invest in to ensure that they cover as much of the spectrum of operations as possible."

Norway and Australia are both obtaining F-35 jets from the United States. So far, Australia has ordered 14 of the aircraft; Norway is purchasing as many as 52.

Australia has not yet committed to purchasing the missile but Australia's early participation in a cooperative JSM development program would "maximize the cost effectiveness of Australia's contribution, and ensure the weapon capability is developed and integrated onto the F-35A in the timeline required by Australia, should the Joint Strike Missile be ultimately considered for acquisition by government later this decade," said Australian Defense Minister Kevin Andrews.

Australia, as with Norway, supplies a number of components and systems for the fighter, which is being produced by a Lockheed Martin-led team involving multiple nations, including Britain, Turkey and Israel.

Australia's first two F-35s were delivered last year and are currently based at an F-35 pilot training center in the United States.

"The (Norwegian) JSM is already a very capable missile, but with the support of Australia, we hope to make it even better, Eriksen Soreide said. "Though Australia is still a few years away from making any final decisions on its future maritime strike capability, we are encouraged by the interest they have shown for both the missile and for the capabilities of Norwegian industry.

"We should now continue talks between our two governments, and aim to formalize this agreement in the near future."

The Norwegian minister visited Australia earlier this week.

The Joint Strike Missile is a long-range precision strike weapon that was designed to fit within the internal weapons bay of the F-35. It features advanced navigation, a passive infrared seeker, low signature and enhanced maneuverability.

Australia will provide Norway its expertise in missile control and guidance systems for the JSF weapon.

Under the second agreement between the Australian Department of Defense's Science and Technology Organization and Airbus Group Australia Pacific, the two are to collaborate on a variety research and development projects in the area of aerospace defense technologies.

DSTO said the collaboration deal, signed at an aerospace exhibition in Australia, would specifically focus on aircraft defense and communications.

"Our collaboration with Airbus Group will ensure the highest levels of support for the ADF's (Australian Defense Force's) future aerospace systems," said DSTO Chief Defense Scientist Dr Alex Zelinsky.

Added Airbus Group Australia Pacific Managing Director Jens Goennemann: "Airbus Group has been good friends and business partners with DSTO for a long time and this strategic alliance can only enhance that successful relationship.

"Combining Airbus Group's aerospace expertise with DSTO's scientific innovation will lead to increased Australian defense capabilities in the future."
