O F-35 em 2020/2025.

sinceramente acho isso um cenário muito optimista

Só falei .... apontei prováveis datas de negociações, porque depois a vinda sejam eles novos ou usados aponto só mesmo 2030. Falei num post atras 25/30 unidades se quisermos manter a mesma estrutura actual duas esquadras cada esquadra equipada com 14 unidades e 2 de reserva.

[typhonman]

Saudações guerreiras

Até posso estar muito enganado. Só faço votos que sim, embora não seja fã do avião, mas há muita gente com ilusões se pensam que mesmo que sejam 20 unidades F-35 - atenção que são nºs atirados ao ar -, os conseguiremos novos.  Apetece-me dizer: lol lol lol lol lol lol lol lol lol

F-35? Sim. Posso admitir isso, mas... em 2ª mão e só quando cá chegarem. Porém, sucata já cá temos. Mais? Não obrigado.

Caros colegas eu gostaria de tirar uma duvida, a quem puder me ajudar um obrigado. Por que a FAP tem de adiquirir ou o F-35 ou o Eurofighter, Portugal não poderia adiquirir o MIG-35 ou o Su-35 ou dependendo do preço e dos acertos o PAK-FA, um grande e sincero abraço a todos.

“F-35 Lightning II Joint Strike Fighter (JSF)

Claim to Fame
The F-35, or Joint Strike Fighter (JSF), is the largest, most ambitious aircraft programme in history when measured by cost. It could grow into one of the largest post-World War Two programmes in numbers of aircraft produced. The USAF wants 1,763 JSFs while the Navy wants 680, to be divided between Navy and Marine units under a formula not yet determined. Britain wants 150 JSFs. Other buyers could include Australia, Canada, Denmark, Israel, Italy, Netherlands, Norway, Singapore and Turkey. Thus the F-35 could become the most-produced fighter in the West, matching the F-16 (4,200 built), the Vietnam-era F-4 Phantom II (5,200) or the Korea-era F-86 Sabre (7,200). The programme is so big that the contest to give the aircraft a popular name yielded finalists including Black Mamba, Cyclone, Spitfire II and Piasa – a mythical man-eating bird, that quickly became ‘Piss-Ass’ in troop talk. The Lightning II appellation was chosen to honour both the Lockheed P-38 of World War Two and the English Electric jet of the Cold War.

Why?
The United States and its allies have a clear need for a next-generation fighter that introduces supersonic speed and stealth to the air-to-ground role. The JSF fills that need with the CTOL (conventional take-off and landing) F-35A, the STOVL (short take-off/vertical landing) F-35B and the carrier-based F-35C. The result is not one aircraft but a family of aircraft. The test of the F-35 will be whether it can succeed in serving many masters to carry out a multitude of missions. Seen by many as a strong point, from the earliest days of what was called the Joint Advanced Strike Technology (JAST) programme in the 1980s, experts insisted this would be a single-engined aircraft, even through almost every fighter in the world had two engines. As an aeronautical engineer said, insistence on a single engine “cut in half the cost of the most expensive item on the plane”. While officials deserve prise for making the F-35 a single-engine airplane, they may be making a mistake in insisting on a single type of engine, the 40,000lbs (180kN) thrust Pratt & Whitney F135 turbofan, for all examples of the fighter. On both sides of the Atlantic, air leaders continue to debate the future of the alternate engine, the similarly powered F136, which would be built by General Electric in partnership with Rolls-Royce. Some observers see the F135 as a reliable engine that is being asked to do too much with dated technology, while the F136 is viewed as having more potential for growth. Policy in Washington has been consistent and the Obama Administration’s fiscal year 2010 defence budget proposal contains no funding for an alternate engine. All three JSF variants have the same set of controls, including a side-stick controller, like the one on the F-16, in place of the conventional joystick found on most fighters.

Conflicts
None yet.

Weaknesses
“This aircraft can’t even carry an infra-red air-to-air missile”, a very senior US officer said, referring to plans to use accelerated F-35 production as a substitute for a larger purchase of F-22s. In Israel, where a purchase of 75 F-35s is likely to be recommended to the Knesset by the Israeli Defence Force, columnist Reuven Pedatzur wrote that the F-35’s “manoeuvring capability is quite poor, perhaps worse than planes that flew missions over Vietnam. Its maximum speed is 1.6 times the speed of the sound; the F-15 can reach 2.5 times. Yet the plane’s biggest problem is probably its miserable payload. To prevent it from being picked up by radar, its munitions must be carried inside the aircraft. As a result, it holds just two bombs. An F-15 can carry a payload eight times as high.” The first vertical flight of the Marine Corps F-35B scheduled for March 2009, was delayed until September. The delays were caused by an engine which failed during tests, ‘tweaking the software controlling the leading edges of the wings and ensuring that the nine doors that open during the STOVL flight all operate correctly The F-35C carrier-based version of the JSF has been delayed by aerodynamic challenges and at the time of going to press was scheduled to make its long-postponed first flight in December 2009. The carrier-based version has an entirely different and much bigger wing – a huge technical change that has not yet been proved in flight.”



“They’re dumping all their eggs into one basket. The STOVL version (F-35B) hasn’t yet demonstrated that it can take off and land vertically or within short distances. The carrier-based version (F-35C) was delayed intentionally and has not flown yet, and may introduce unexpected aerodynamic Challenges. If the whole F-35 thing comes together and the programme functions smoothly, it will be a brilliant achievement. If it doesn’t, you’ll see US industry selling new American variants of the F-16 and F-15.

A senior office who worked closely with the office of the US Air Force Chief of Staff, 2007-2009.”



“The F-35 was designed to operate and survive in high-threat battle-space defined by advanced surface-to-air missile systems, and while outnumbered by top-of-the-line fourth generation fighters, is a distinct probability. The F-35 will incorporate the most advanced net-enabled mission systems, sensor and communication systems suite ever fielded in a fighter aircraft. It will be a key database in the kind of information-collection and distribution networks so valuable to sea, land and air forces today and in the future.

Steve O’Brien, Lockheed Martin vice-president of F-35 business development, speaking at a Navy League trade show, May 1, 2009.”

“Reality Check: JSF’s Phantom Export Variant

(Source: defense-aerospace.com; published June 18, 2009)

The JSF Program Office says no “dumbed-down” F-35s are planned for international partners, but Lockheed Martin has been awarded contracts worth $737 million to develop one. (JSF Team photo)PARIS --- Are the United States developing a “dumbed-down” version of the F-35 Joint Strike Fighters for export customers, or not? Brigadier Gen. David Heinz, program executive officer for the F-35, rejected a claim by Boeing executives that Washington was selling a "dumbed down" version of the F-35 to international partners, Reuters reported June 16 from the Paris Air Show.

"I state categorically that I am not doing a different variant of aircraft for my international partners today," Reuters quoted Heinz as saying in an interview. He said foreign countries who bought the F-35 would be subject to a U.S. disclosure process and U.S. export controls, but [that] the aircraft being sold today were the same airplanes that were also being built for the U.S. military services. "So for Boeing to make statements about a 'dumbed down' variant ... is absolutely incorrect and it is speculative and I believe, a very disappointing marketing ploy to drum up business" [for its F-15 Silent Eagle], Heinz added.

Heinz appears to be suffering a bad case of memory lapse, however, as the Pentagon has in fact awarded Lockheed Martin two separate contracts, worth a total of $737 million, to develop such an export version of JSF or, in Pentagon-speak, to “design, develop, verify and test a version of the JSF air system that is as common as possible to the U.S. air system within the National Disclosure Policy.” This version is designated “International Partner Version.” (see below).

As we noted in a Nov. 26, 2007 story on the subject, “This raises the question of exactly how this degraded “Delta SDD” version will differ from the standard US version, and which capabilities and features will be removed to comply with US national disclosure policy. Given that the JSF’s high-tech features, including stealth, and the capabilities of its electronic systems are the prime reasons which attracted foreign partners in the first place, it remains to be seen whether they will remain as committed to a degraded, less capable yet more expensive aircraft.” This still stands today.

Heinz’s categorical June 16 statement to Reuters can be read to imply either that work on the JSF export version has been dropped as quietly as it was originally launched, or that the JSF program office is trying to keep it secret so as not to scare off potential export customers who might not be interested in a “dumbed-down,” less capable aircraft. In any case, a clarification is urgently needed.


These are the two contracts awarded to date for the JSF’s export version:

November 10, 2003

Lockheed Martin Corp., Lockheed Martin Aeronautics Co., Fort Worth, Texas, is being awarded a $602,594,580 cost-plus-award-fee modification against a previously awarded contract (N00019-02-C-3002) for the procurement of supplies and services to support the performance of the Joint Strike Fighter (JSF) International Partner Version Delta Systems development and demonstration effort.

Lockheed Martin will design, develop, verify and test a version of the JSF air system that is as common as possible to the U.S. air system within the National Disclosure Policy.

Lockheed Martin will also implement a manned tactical simulation (MTS) capability, hold MTS events for the international partners on the JSF Program and conduct planning for future efforts and upgrades.

Work will be performed in Fort Worth, Texas (83 percent); El Segundo, Calif. (10 percent); and Orlando, Fla. (7 percent), and is expected to be completed by April 2012. Contract funds will not expire at the end of the current fiscal year.

The Naval Air Systems Command, Arlington, Va., is the contracting activity.


November 15, 2007

Lockheed Martin Corp., Lockheed Martin Aeronautics Co., Ft. Worth, Texas, is being awarded a $134,188,724 modification to a previously awarded cost-plus-award-fee contract (N00019-02-C-3002).

This modification is to continue the design, development, verification, and test of Joint Strike Fighter (JSF) Partner Version Air System development under the JSF Delta System Development and Demonstration Effort (Delta SDD).

The purpose of the Delta SDD is to develop a version of the JSF Air System that meets U.S. National Disclosure Policy, but remains common to the U.S. Air System, where possible.

Work will be performed in Fort Worth, Texas (68 percent), Orlando, Fla. (24 percent), and El Segundo, Calif. (8 percent), and is expected to be completed in October 2013. Contract funds will not expire at the end of the current fiscal year.

The Naval Air Systems Command, Patuxent River, Md., is the contracting activity.”

Pentagon Study Shows F-35 Jet to Cost More—Report (excerpt)
   
   
(Source: Reuters; published Oct. 23, 2009)
 
 
   
   WASHINGTON --- A new Pentagon study has affirmed previous findings that Lockheed Martin Corp's F-35 Joint Strike Fighter aircraft, the costliest U.S. arms purchase program, will require billions of dollars more than planned, and more time, an online news service said on Friday.

A military "Joint Estimate Team" tasked in July to examine the program has found the F-35 program's performance "is not markedly improving," InsideDefense.com said, citing an unidentified source.

Lockheed is developing three radar-evading F-35 models to replace at least 13 types of aircraft, initially for 11 nations.

The United States plans to buy 2,443 F-35s. Purchases by partner nations Britain, Canada, Italy, Denmark, Netherlands, Norway, Turkey and Australia and others could raise production to 3,000 or more.

Northrop Grumman Corp and BAE Systems Plc are Lockheed's chief F-35 sub-contractors.

"A new assessment of the Joint Strike Fighter program affirms earlier findings that substantially more money and time are required for the Pentagon's largest acquisition effort, a conclusion that could pose a formidable test of Defense Secretary Robert Gates' recent support for the F-35 program and President Barack Obama’s pledge to terminate weapons with bloated price tags," InsideDefense.com reported.

Its headline said the program would need "billions" more.

Obama vowed in March to reform the Pentagon's procurement practices and to crack down on programs that run over budget.

Earlier this year, Defense Secretary Robert Gates decided to cap production of the Lockheed F-22 fighter at 187 planes, citing his support for the $300 billion F-35 program.

The study was undertaken to update one last year that found the program would need at least two more years and nearly $15 billion more.

"The initial results are as bad as last year's," InsideDefense.com quoted its source as saying. "In other words, things have not improved. And their cost estimate will be at least where they were last year."

In response, Bethesda, Maryland-based Lockheed Martin, the Pentagon's No. 1 supplier by sales, said it disagreed with the joint estimate team conclusions.

"Lockheed Martin acknowledges that modest risks to our cost and schedule baselines exist," said John Kent, a company spokesman, "but we envision no scenario that would justify a substantial delay to completion of development or transition to production milestones." (ends of excerpt)

Northrop Grumman Begins Producing First International F-35 Joint Strike Fighter

Milestone Adds Momentum to Early Production Phases of Multi-National Fighter Program

13:48 GMT, October 30, 2009 PALMDALE, Calif. | Northrop Grumman Corporation (NYSE:NOC) has begun producing the center fuselage for the first international F-35 Joint Strike Fighter, an F-35B short take off, vertical landing (STOVL) variant for the United Kingdom designated BK-1. The center fuselage is the core structure around which the F-35 aircraft is built.

The assembly process began Oct. 26 at the company's Palmdale Manufacturing Center with the loading of an all-composite air inlet duct into a special tooling structure called a jig. This first assembly process, one of approximately 18 major steps in assembling an F-35 center fuselage, consists of attaching metal frames around the duct. The frames serve to brace and position the duct properly within the center fuselage.

"Jig loading the BK-1 center fuselage for the United Kingdom's first F-35 demonstrates that the program is delivering on its promise to produce a fifth generation, multi-role fighter that meets the common air combat requirements of the U.S. and its allies," said Mark Tucker, vice president and F-35 program manager for Northrop Grumman's Aerospace Systems sector. "Through a disciplined approach to managing costs and engineering changes, we're continuing to reduce program risks, which will help the F-35 industry team put jets on the ramp on or before the initial operational need dates of our international partners."

Tucker noted that the company had started assembling the BK-1 center fuselage three days sooner than the date indicated by the F-35 program's master schedule.

Northrop Grumman is a principal and founding member of the F-35 industry team led by Lockheed Martin. To date, the company has delivered 25 center fuselages -- 19 for the system development and demonstration phase, six for the low rate initial production (LRIP) phases of the program. BK-1 is being produced as part of LRIP3. The program is scheduled to produce 138 F-35Bs for the United Kingdom.

Final assembly of all F-35 jets is performed by Lockheed Martin at a facility in Fort Worth, Texas. The process includes mating a Northrop Grumman-built center fuselage to an aft fuselage produced by BAE Systems, and the forward fuselage/cockpit and wings produced by Lockheed Martin.

Northrop Grumman is responsible for the design and production of center fuselages for all three variants of F-35 aircraft: conventional takeoff and landing; short takeoff, vertical landing; and the carrier variant. The F-35 Lightning II program expects to build more than 3,100 aircraft.

As a member of the F-35 global industry team, Northrop Grumman is central to the development, production and support of the F-35 Lightning II. The company designed and produces the aircraft's center fuselage, radar and other key avionics including electro-optical and communications subsystems; develops mission systems and mission-planning software; leads the team's development of pilot and maintenance training system courseware; and manages the team's use, support and maintenance of low-observable technologies.

F-35: muito barulhento para os padrões europeus



Um relatório classificado da Lockheed Martin sobre o nível de ruído do F-35 vazou na Noruega e está tendo grande repercussão.

No documento o nível de ruído do F-35 é apontado como sendo 4 vezes superior ao da última versão do F-16, que é mais ruidosa que a versão usada na Noruega.

Vários países europeus, incluindo a Noruega, Holanda e Suíça, têm leis muito rigorosas que regem os níveis máximos de ruído dos aviões que os residentes nas proximidades dos aeroportos, aeródromos e bases aéreas podem ser submetidos.

Essas leis podem obrigar medidas de redução de ruído, incluindo a remoção de casas obrigatoriamente, por conta do governo.

Na Noruega pensa-se em desativar bases muito próximas à população ou afastar casas de moradores para mais longe das bases. Mas ambas as medidas terão custo elevado.
