Lockheed's Stevens Says F-35 May Need `More Time, More Dollars'

The development phase of Lockheed Martin Corp.’s F-35 jet fighter, the most expensive U.S. weapon program, will likely take longer and more money than expected to complete, Chief Executive Officer Robert Stevens said.

The U.S. Defense Department and the company are “probably going to examine the need for more time, more people and more dollars,” Stevens said in an interview today in Washington.

The Pentagon is conducting a so-called Technical Baseline Review, led by F-35 program manager Vice Admiral David Venlet, in time for a scheduled Nov. 22 Defense Acquisition Board evaluation. The review may disclose broad ranges of potential cost increases and schedule delays on top of changes unveiled this year by the Pentagon, two government officials with knowledge of the program said this week.

The F-35 Joint Strike Fighter model being designed for the U.S. Marine Corps, with a short-takeoff and vertical-landing capability, is behind schedule, Stevens said.

“We have to improve the performance of that airframe,” he said. “The software has been performing well when it’s on the aircraft, but it’s going to take some more resources.”

The Pentagon has already mandated a 13-month extension to the current development phase to November 2015, shifting $2.8 billion in production funds for continued research and delaying the purchase of 122 jets to beyond 2015. The weapon program is estimated to cost $382 billion.

Lockheed, based in Bethesda, Maryland, advanced $1.03, or 1.5 percent, to $71.96 at 4:15 p.m. in New York Stock Exchange composite trading. The shares have declined 4.5 percent this year.

Marine Corps Model

The Marine Corps model is the most complex of the three versions being developed and has fallen short of flight-test goals. As of Oct. 31, it has flown 168 times compared with a target of 209 tests, John Kent, a Lockheed spokesman, said in a statement today. Including flight tests of the Navy’s carrier- variant and the conventional-takeoff model, the plane has completed 321 flights, 28 more than planned by October, he said.

The model’s basic flying characteristics, propulsion system and structural integrity “are performing well,” Stevens said. By contrast, “supplier-provided components” such as cooling fans “are not demonstrating early reliability,” he said.

As a result, Lockheed is focusing more attention than planned on correcting supplier deficiencies. “That takes time, and that means we’re going to have to re-examine the flight-test schedule and program,” he said.

‘Reallocate Resources’

The Pentagon review led by Venlet is looking at program changes in the past year and asking, “how has performance unfolded, are we doing that which we expected on plan, are we better than planned, are we behind and, importantly, how do we reallocate resources to assure this program is successful,” Stevens said.

The $50 billion development phase may cost as much as $5 billion more, according to preliminary estimates in Venlet’s review, the two government officials said on condition of anonymity because the review hasn’t been made public yet.

Separately, Pentagon cost analysts now estimate the JSF may be as much as 1 1/2 times more expensive to maintain than the warplanes it will replace.

Slippage in the JSF’s timetable may be as much as one year for the Air Force and Navy versions, and two to three years for the Marine Corps model, the officials said.

Leaks Regretted

Pentagon spokesman Geoff Morrell today criticized release of the information, noting “the department regrets that someone chose to provide unauthorized and incomplete information to the press.”

“Admiral Venlet has been doing a soup-to-nuts review of the JSF program,” Morrell said. “It is the most thorough, the most extensive, the deepest dive yet we have done into the F-35 program.”

“But that assessment is not yet complete,” he said. “Therefore, what has been leaked to the press is premature, and I would suggest to you that in some respects it’s inaccurate.”

Stevens and Joseph Dellavedova, a U.S. Air Force F-35 program spokesman, said separately that the first two production aircraft, which were supposed to be delivered this month to Edwards Air Force Base, California, are undergoing modifications and will be delivered in April.

Pelo menos politico é igual em todo lugar. Ainda sobre a divisão do contrato da turbina do F-35:
GOP civil war on defense

By GORDON LUBOLD | 11/12/10 12:19 PM EST

A proposal to slash $100 billion from the Pentagon budget threatens to spark a civil war within the GOP — pitting hard-core deficit hawks against some members who view military spending as sacrosanct and others who represent districts reliant on defense-related jobs.

The chairmen of President Barack Obama's bipartisan deficit reduction commission Wednesday proposed cutting several major weapons programs, from the Marine Corps’ Expeditionary Fighting Vehicle to the Navy’s Future Maritime Prepositioning Force.

Some of the cuts will be non-starters. But the proposal exacerbates the tension already roiling Republicans who rode to victory last week on promises of smaller government.

“Peace through strength can’t be accomplished through a waste of money,” Oklahoma Sen. Tom Coburn told POLITICO earlier this week. “We’re buying stuff we don’t need.”

Coburn has proposed freezing Pentagon spending, which has nearly doubled since 2002. He'd then conduct a major audit, to be followed by $50 billion in cuts. Coburn has the support of some tea party favorites such as Sen.-elect Rand Paul from Kentucky, who said Sunday on ABC’s “This Week” that he also would seek cuts at the Pentagon.

It runs in the family. His father, Rep. Ron Paul (R-Texas), appeared on MSNBC’s “The Dylan Ratigan Show” Wednesday decrying Republicans afraid or unwilling to cut defense spending. “That bothers me that freshmen are coming in with that attitude,” Paul said. “You know conservatives are going to argue you don’t cut a nickel out of military, I say that’s not defense, that’s military, and we should look at it.”

And the tea party is by no means in harmony on this issue: Sarah Palin is among those conservatives who draw the line at defense spending.

And for Republicans like California Rep. Buck McKeon, who's poised to become chairman of the House Armed Services Committee, defense spending is all but sacred — especially with U.S. troops still fighting in Iraq and Afghanistan.

“You need to make sure our troops, those that are out there laying their lives on the line for us, have everything they need to do their mission and return home safely,” McKeon told POLITICO. “Any cuts in the defense budget would hurt that.”

At issue is everything from Washington, D.C., Metrorail subsidies for Pentagon employees to how many ships the Navy builds and where. But for some members, including speaker-in-waiting John Boehner, the issue that hits closest to home may be a proposed second engine for the F-35 Joint Strike Fighter, which would be assembled just outside of his district in southwestern Ohio.

The JSF is the military’s future combat aircraft, and the Pentagon has sunk billions of dollars into the department’s most expensive aircraft acquisition program. But some members of Congress want to split the contract for its engine into two: one engine would be made by Pratt & Whitney, with a second engine built by GE and Rolls Royce.

Defense Secretary Robert Gates has called the second engine "costly and unnecessary," and Sen. John McCain (R-Ariz.) has criticized the proposal to build it as just "another bite at the apple" after the Pratt & Whitney proposal won out.

But proponents say the second engine would stimulate competition and save money. Boehner is among them; he cites competition as driving down costs. “According to objective observers like the GAO, competition will save taxpayers’ money in the long run,” Boehner spokesman Michael Steel told POLITICO.

Boehner is hardly the only member with parochial interests at stake; the second-engine proposal would mean jobs in districts from Florida to Indiana, and members on both sides of the aisle would like to protect them.

There are similar drivers on the other side of the debate; assembly of the Pratt & Whitney engine occurs in Middletown, Conn., and Sen. Joe Lieberman (I-Conn.) has lined up against the competition from GE and Rolls Royce.

Some sources inside the Pentagon believe the midterm election handed proponents of the second engine the power they need to cut a deal with the administration, which threatened a veto on the second engine, especially with Boehner and McKeon in leadership positions. The second engine has friends in the Senate as well, including Armed Services Committee Chairman Carl Levin (D-Mich.)

Meanwhile, Gates has made a priority of making the Pentagon budget more efficient — if only to prevent a meat-ax approach later. The fiscal 2012 budget proposal in February will likely include a number of new cuts, influenced in part by the wave of debt-reduction talk in Washington, even if he proposes that the overall defense budget will grow slightly.

Gates is already trying to head off budget hawks by proposing budgetary “efficiencies.” Overall, he wants to find $100 billion in savings over the next five years, money he promises the Pentagon can reinvest in more efficient, relevant programs. And last year, he cut or curtailed about 20 “troubled or excess” programs. But Gates the pragmatist knows it’s not enough to ward off the threat of bigger cuts.

Last month, he hosted the two co-chairs of the deficit commission, Erskine Bowles and Alan Simpson, for lunch at the Pentagon. Gates’s stated position on the budget is that defense spending cannot continue to rise at anywhere near the rate it has over the past nine years — but nor should it shrink. He believes that to sustain the Pentagon’s current “force structure” and modernization efforts will require 2 to 3 percent in annual real growth in spending.

But sources inside the building say it's better to trim the budget now than to suffer the catastrophic damage that runaway deficit spending would someday bring.

“Deficit Hawks want to drive down debt and interest, which ultimately could KILL defense, so they are right to want to solve the problem,” one senior Pentagon official said via e-mail. “The tea party folks are neo-isolationist, and they want a smaller and cheaper government, so they will echo the Deficit Hawks.” But "re-shaping” the defense budget will occur over the decade, the official wrote, and no time soon.

And whenever it comes, it won't be easy.

The drawdown of troops in Iraq will yield some savings that deficit hawks have their eye on. But McKeon and others think that money is needed for “re-set” costs to fix all the military equipment that's been destroyed or worn out in war.

“We always ask the generals, 'What would you do with extra money?'” McKeon said. “They always have plenty of good ideas.”

As aparencias enganam Tulio, no F-35 mesmo a Navy manteve o canhão, enquanto a USAF não; preferiu esquecer as lições aprendidas no passado e utilizadas hoje no Afeganistão.

A Navy partiu para uma versão mais moderna do F-18, enquanto a USAF defecou para o F-15 e F-16 investindo todas as fichas na dupla F-22/F-35; o que estamos vendo não se provou uma decisão acertada, e hoje por causa disso ela deve ter que aproveitar os pacotes feitos para outros paises (F-16 BL60+/ F-15 SE) para cumprir um GAP que ela mesmo criou.

Ambas tem defeitos e qualidades, mas algums so vêem os tombos que a gente leva...

Sei lá. F-35 naval é uma incógnita (terrestre idem). F-22 é aquilo que a gente sabe. F-18 encolheu o envelope do original em alguns aspectos sem sanar inteiramente seu grande defeito, o alcance. Que o Tomcat tinha de sobra, além daquele radarzão...

Já F-15/16 estão aí, aproveitando ou não programas desenvolvidos para estrangeiros. E são tão mortíferos quanto qualquer Eurocanard...

Concordo, mas o meu ponto é que a NAVY previu esse GAP e manteve a atualização do F-18, diferente da USAF que colocou todas as fichas na dupla F-22/F-35, a coisa não andou como se esperava e agora ela está correndo atrás do prejuizo.

Sobre o F-14, acredito que seja mais um erro de julgamento.
Bom, talvez seja cedo para dizer que foi um erro, mas acho que a NAVY acreditou que com as caracteristicas do F-35 não seria mais necessario uma performance como a do TOMCAT e optou pelo Stealth ao inves do tamanho e alcance.

Hoje tudo leva a crer que a tecnologia prometida não era tão boa assim e que talvez a aposentadoria do F-14 tenha sido muito cedo, tanto é assim que o A-6 (que tambem ia ser substituido) continua firma e forte.

O problema do F-14 era a manutenção caríssima, até mesmo para os padrões da USN. Já a USAF pagou o preço de ter uma proximidade "demasiada" da LM...

Permitam-me citá-los a ambos, amigos, simplifica a resposta.


Sobre os prometidos (e cada vez mais aparentemente INCUMPRIDOS) milagres da tecnologia stealth, é por aí mesmo. Sobre o alto custo de manutenção do Tomcat, prendia-se às frágeis e complicadas turbinas e às asas de geometria variável. Para se ter uma idéia, a turbina do F-18 de hoje é uns 10% mais potente que as TF-30 e o avião teria espaço inclusive para algo MAIOR, como as F-110. E desde o início do projeto havia uma proposta de versão de asa fixa, dobrável.

Agora imaginemos aquele radarzão do problemático Raptor no nariz de um Tomcat 'state-of-the-art' com asas fixas, bobear e até a USAF largava o F-15 E O F-22...


Mas é passado, e eles estão aí, se virando com o que têm... :wink: 8-]
