JSF's Build And Test Was 'Miscalculation,' Adm. Venlet Says; Production Must Slow

"The analyzed hot spots that have arisen in the last 12 months or so in the program have surprised us at the amount of change and at the cost," Vice Adm. David Venlet said in an interview at his office near the Pentagon. "Most of them are little ones, but when you bundle them all up and package them and look at where they are in the airplane and how hard they are to get at after you buy the jet, the cost burden of that is what sucks the wind out of your lungs. I believe it's wise to sort of temper production for a while here until we get some of these heavy years of learning under our belt and get that managed right. And then when we've got most of that known and we've got the management of the change activity better in hand, then we will be in a better position to ramp up production."

Saudações guerreiras

Relacionado com o F-35, e só para terem uma ideia da loucura que tem sido este programa desde o inicio. O 2º motor (F136), que nunca foi aceite de bom grado pelos EUA, foi oficialmente “posto de lado” pelos próprios (General Electric e RollsRoyce), devido a incertezas quanto a viabilidade do programa passar á fase de produção em escala.

Mais em concreto em:

Em jeito de roda pé. Um olhar pelos comentários da noticia colocada pelo “borisdedante”. Há muita gente sensata a pedir o cancelamento definitivo do programa.

Japan Selects Lockheed Martin F-35 Lightning II

FORT WORTH, Texas, December 19th, 2011 -- The Japan Ministry of Defense has announced its selection of the Lockheed Martin [NYSE: LMT] F-35 Lightning II as the Japan Air Self Defense Force’s (JASDF) next generation fighter aircraft, following the F-X competitive bid process. The F-35A conventional takeoff and landing variant (CTOL) was offered by the United States government with participation from Lockheed Martin. The initial contract will be for four jets in Japan Fiscal Year 2012, which begins April 1, 2012.

"We are honored by the confidence the Japanese government has placed in the F-35 and our industry team to deliver this 5th Generation fighter to the Japan Air Self Defense Force," said Bob Stevens, Lockheed Martin chairman and chief executive officer. "This announcement begins a new chapter in our long-standing partnership with Japanese industry and builds on the strong security cooperation between the U.S. and Japan."

Global participation is a centerpiece of the F-35 program and essential for its success and affordability through economies of scale. The program is comprised of nine partner nations: the United States, United Kingdom, Italy, Netherlands, Turkey, Canada, Australia, Denmark and Norway. The United Kingdom and Netherlands have ordered test aircraft, and Italy and Australia have committed long-lead funding for their initial operational aircraft. In October 2010, Israel selected the F-35A as the Israel Air Force’s next generation fighter and is scheduled to receive the F-35 through the U.S. government’s Foreign Military Sales process.

The F-35 Lightning II is a 5th Generation fighter, combining advanced stealth with fighter speed and agility, fully fused sensor information, network-enabled operations and advanced sustainment. Lockheed Martin is developing the F-35 with its principal industrial partners, Northrop Grumman and BAE Systems.

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 126,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s 2010 sales from continuing operations were $45.8 billion.

Ministro britânico preocupado com o futuro do programa F-35


O ministro britânico da Defesa, Philip Hammond, disse estar preocupado com as consequências dos cortes orçamentais americanos sobre o programa dos caças F-35, que o Reino Unido tinha previsto adquirir para equipar o seu futuro porta-aviões.

«Uma das coisas que eu espero perceber durante os encontros que irei ter é o impacto que terão os anúncios de hoje [quinta-feira] no programa do Joint Strike Fighter», o futuro avião caça F-35 com capacidades furtivas, declarou o ministro britânico na quinta-feira, em Washington, perante o Conselho Atlântico.

Hammond encontrou-se com o seu homólogo americano Leon Panetta horas depois do anúncio do presidente Barack Obama de uma nova estratégia para o exército americano, que prevê cortes de 487 mil milhões de dólares (380,6 mil milhões de euros) nos próximos 10 anos.

   U.S. Arms Buyer Says F-35 Jet Purchase Was Bungled (excerpt)
   
   
(Source: Reuters; published Feb 6, 2012)
 
 
   
   WASHINGTON --- The Pentagon's initial plan to start producing Lockheed Martin Corp $382 billion F-35 Joint Strike Fighter years before testing was complete amounted to "acquisition malpractice," the Defense Department's acting chief arms buyer said on Monday.

"Now we're paying the price," Frank Kendall, acting defense undersecretary for acquisition, technology and logistics, said at an event sponsored by the Center for Strategic and International Studies.

Kendall said the initial approach of having concurrent work on development and production was problematic, but the Pentagon was managing the program carefully and remained committed to the new radar-evading fighter. (…/…)

Kendall said problems on the plane so far were typical of those experienced by other big new aircraft programs, and he had not seen anything that would prevent the continuation of production at the current low rates. (…/…)

He said Pentagon planned had counted on improved design tools and modeling to catch possible problems with the new jet, when they decided to move into low-rate initial production even before the airplane was tested, but those design tools failed. (end of excerpt)

ANALYSIS: F-35 LRIP 5 Contracts: Unit Cost Tops $200M for First Time
   
   
(Source: defense-aerospace.com; published Mar. 12, Updated Mar. 13, 2012)
 
   
   By Giovanni de Briganti
 
PARIS --- Previously estimated at nearly $160 million, the unit price of F-35 fighters ordered as part of the fifth Low-Rate Initial Production batch (LRIP Lot 5) has now passed $200 million, once additional contracts awarded by the Pentagon since our previous estimate on Dec. 9, 2011 are included.

On that date, when DoD awarded the main Lot 5 Low Rate Initial Production (LRIP 5) contract worth $4,011,919,310 for 30 aircraft, we had estimated average unit costs at $159.7 million.

However, after recent claims by US Air Force and program officials that F-35 acquisition costs are being reduced as better prices are negotiated with contractors, we updated our cost estimate.

Unsurprisingly, F-35 prices in fact show no sign of decreasing, and the total cost of LRIP Lot 5 further increased after two additional contracts awarded in late December.

Intriguingly, the Pentagon picked December 27 – two days after Christmas, in what is arguably the slowest news week of the year – to award two additional LRIP 5 contracts. Had it wanted to hide these awards, it would hardly have acted differently.

One contract, worth $485,000,000, is for LRIP 5 “non-recurring requirements,” which adds $16.6 million to the price of each of 30 LRIP 5 aircraft.

The second contract, awarded to Pratt & Whitney, is for production of 30 F135 engines for the LRIP 5 aircraft, and is worth $1.12 billion; it adds an average of $37.4 million to the cost of each aircraft.

We also identified a further LRIP 5 contract not previously included in our LRIP 5 estimate: it was awarded May 10, 2010, and covers F135 engine long lead items for this batch to the value of $138.8 million. At the time, LRIP 5 included 42 aircraft, so the contract’s cost works out to $3.3 million per aircraft.

Including these three, the Pentagon has awarded five contracts, together worth $6,280 million, to fund 30 LRIP 5 aircraft, whose average unit cost – engines included -- is thus $203.4 million.

Here is an updated breakdown of this estimate:



There are two caveats, however, to the above unit cost:

1. It does not include the cost of the modifications, retrofits and upgrades that will be necessary to bring all LRIP aircraft to their nominal configuration, once flight testing and development are completed. The estimated cost of these modifications, known as concurrency costs, varies between $5 million (Lockheed Martin) and $10 million per aircraft (US Senate panel).

The JSF program office has not released its own estimate, but Venlet in December said the bill for fixing concurrency ills was so high it "sucks the wind out of your lungs."

2. Several of these LRIP 5 contracts include cost escalation clauses (“cost plus incentive contract line items”; “fixed-price-incentive (firm target)”; “cost-sharing/no-fee basis,” and “not-to-exceed cost-plus-fixed-fee”), so their actual cost will increase before they are completed.

Updated March 13, 2012
The award of additional contract fees and reimbursements has already begun. On March 12, the Pentagon announced it had awarded Lockheed:

"a $56,329,396 cost reimbursement modification to previously awarded contract (N00019-10-C-0002) to provide additional funding for the sustainment effort necessary to meet the requirements and delivery schedule for the F-35 Low Rate Initial Production V."

This contract adds another $1.9 million to the cost of each LRIP 5 aircraft, and more awards of this kind are to be expected.

It is thus inevitable that LRIP 5 costs will increase further, and by a substantial margin, as major re-design and modifications will be required, for example to fix the non-functional F-35C tail-hook and other design flaws.

Cost Varies Substantially by Version

Originally set at 42 aircraft, the F-35 Low Rate Initial Production Lot 5 now comprises 30 aircraft:
-- 21 Conventional Take Off and Landing (CTOL) aircraft for the US Air Force;
-- 6 Carrier Variant (CV) aircraft for the US Navy, and
-- 3 Short Take Off and Vertical Landing (STOVL) aircraft for the US Marine Corps.

Given the information provided in each Lot 5 contract announcement, it is possible to compute, with a degree of accuracy, the cost of each version of the F-35. If the average cost is $203.4 million per aircraft, it in fact varies substantially according to the version:

-- F-35A: $172 million per aircraft;
-- F-35B: $291.7 million per aircraft;
-- F-35C: $235.8 million per aircraft.

This is a breakdown of LRIP 5 contracts and resulting unit costs, by version.



While these are the projected unit costs for the LRIP 5 aircraft, there is no implication that production aircraft would cost anywhere near these amounts.

However, costs will not begin to decrease until the F-35 enters full-scale production, and this is unlikely to happen for some years yet, especially since the Pentagon has now decided to further reduce LRIP production until flight tests demonstrate that the aircraft is meeting its performance and reliability goals.

Delaying orders for 179 LRIP aircraft for five years, part of the Pentagon’s FY2013 budget request, will save over $15 billion in the short term, but will ultimately further increase unit costs for the remaining aircraft.

F-35 Low-Rate Initial Production Lot 5 Contracts:

The Pentagon has awarded five main contracts for the Lot 5 Low-Rate Initial Production, listed below.

These should have been fixed-price contracts, following former Defense Secretary Robert Gates’ decision to stop cost-plus contracts for this program. However, this is not the case, as we have highlighted in bold characters below.

This allows for a further increase in contract costs if the contractors incur higher than expected costs.

United Technologies Corp., Pratt & Whitney Military Engines, East Hartford, Conn., is being awarded an advance acquisition contract with an estimated value of $138,800,000 for long lead components, parts and materials associated with the Lot V low rate initial production of 22 F135 conventional take-off and landing propulsion systems for the Air Force; 13 short take-off and vertical landing propulsion systems for the Marine Corps; and 7 carrier variant propulsion systems for the Navy.
