F35 アップグレードは誰が行う

F35開発は前途多難なようだ。
 米国防総省高官は、F35を電子制御するソフトウエア・プログラム
について、共同開発に参加している英国に公開しないことを明らかにした。
 ソフトウエアは、F35の電子頭脳の中枢部。英国は「ソースコード」
の共有を求めており、認められなければ計画からの離脱も示唆してきた。

800万行によるソース・コードと呼ばれるソフトウェアは、ロッキードが
アップグレードを繰り返すことで、改修が可能としたようだ。
開発予算は166億ドル程度らしいが、経費はもう使い果たしてしまった
ようだ。英国は20億ドルを提供したが、F-35の開発はまだ完了せず、
ソース・コードも非公開と言うことになれば、英国は撤退し、出資した
開発費を引き上げる可能性もある。
8ヵ国による共同資金による開発も参加国では歓迎されていない。
シンガポールは、共同資金による開発を決めたようだ。
F-35は各国の受注数が数千機単位。日本は、数十機単位。
日本が参加しても、不明瞭な仕様に大金を支払い、高額な開発費を要求
され、アップグレードによる費用も別途要求されるのだろう。
足元をみられているのだろう。

 米国防総省高官は24日、ロイター通信に対し、次世代戦闘機F35を電子制御するソフトウエア・プログラムについて、共同開発に参加している英国に公開しないことを明らかにした。
 機密保持とともに、米国の戦闘機開発での優位性を保つためとみられる。イタリアやオランダなど他の共同出資国にも公開しない考え。

---U.S. to withhold F-35 fighter software code

WASHINGTON (Reuters) - The United States will keep to itself sensitive software code that controls Lockheed Martin Corp's new radar-evading F-35 fighter jet despite requests from partner countries, a senior Pentagon program official said.

Access to the technology had been publicly sought by Britain, which had threatened to scrub plans to buy as many as 138 F-35s if it were unable to maintain and upgrade its fleet without U.S. involvement.

No other country is getting the so-called source code, the key to the plane's electronic brains, Jon Schreiber, who heads the program's international affairs, told Reuters in an interview Monday.

"That includes everybody," he said, acknowledging this was not overly popular among the eight that have co-financed F-35 development -- Britain, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway.

The single-engine F-35, also known as the Joint Strike Fighter, is in early stages of production. It is designed to escape radar detection and switch quickly between air-to-ground and air-to-air missions while still flying -- tricks heavily dependent on its 8 million lines of onboard software code.

Schreiber said the United States had accommodated all of its partners' requirements, providing ways for them to upgrade projected F-35 purchases even without the keys to the software.

"Nobody's happy with it completely. but everybody's satisfied and understands," he said of withholding the code. It is also a rebuff to Israel, which has sought the technology transfer as part of a possible purchase of up to 75 F-35s.

REPROGRAMMING FACILITY

Instead, the United States plans to set up a "reprogramming facility," probably at Eglin Air Force Base in Florida, to further develop F-35-related software and distribute upgrades, Schreiber said.

Software changes will be integrated there "and new operational flight programs will be disseminated out to everybody who's flying the jet," he said.

Representatives of the British defense staff in Washington did not return telephone calls seeking comment. Britain has committed $2 billion to develop the F-35, the most of any U.S. partner.

In March 2006, Paul Drayson, then Britain's minister for defense procurement, told the U.S. Senate Armed Services Committee that Britain might quit the program if the United States withheld such things as the software code.

The issue rose to the top. In May 2006, then-President George W. Bush and then-Prime Minister Tony Blair announced that both governments had agreed "that the UK will have the ability to successfully operate, upgrade, employ, and maintain the Joint Strike Fighter such that the UK retains operational sovereignty over the aircraft."

HOLY GRAIL

The source code is "kind of the holy grail" for this, controlling everything from weapons integration to radar to flight dynamics, said Joel Johnson of TEAL Group, an aerospace consultancy in Fairfax, Virginia.

Lockheed Martin said all F-35 partners "recognize the complexity of the highly integrated F-35 software and the program plan to upgrade F-35 capabilities as an operational community."

"This enables the aircraft to remain at the cutting edge of combat capability while allowing the program to meet affordability objectives," John Kent, a company spokesman, said in an emailed statement.

Schreiber said Singapore had signed a special security agreement last month, clearing the way for it to receive classified information on F-35s it could buy.

Lockheed, the Pentagon's No. 1 supplier by sales, projects it will sell up to 4,500 F-35s worldwide to replace its F-16 fighter and 12 other types of warplanes for 11 nations initially.

The United States plans to spend roughly $300 billion over the next 25 years to buy a total of 2,443 F-35 models, its costliest arms acquisition.

Competitors include Boeing Co's F/A-18E/F SuperHornet; Saab AB's Gripen; Dassault Aviation SA's Rafale; Russia's MiG-35 and Sukhoi Su-35; and the Eurofighter Typhoon, made by a consortium of British, German, Italian and Spanish companies.

---防衛省、次期戦闘機F35採用へ 約40機の導入想定---

 防衛省は航空自衛隊の次期主力戦闘機(FX)について、次世代戦闘機F35を採用する方向で調整に入った。12月から選定作業を本格化させ、2011年度の概算要求にF35の契約金など関連経費を盛り込みたい考えだ。複数の防衛省・自衛隊関係者が22日、明らかにした。
 F35はレーダーに捕捉されにくいステルス機能が最大の特徴。中国が最新の第4世代機など航空戦力を増強させる中、防空能力の向上が不可欠と判断した。最終的には40機程度の取得を想定している。
 ただF35は開発中で配備が10年代半ばと見込まれる。このため性能の確定まで契約を先送りすべきだとの慎重論があり、12年度予算へ先送りされる可能性も残っている。
 政府は新たな「防衛計画の大綱」とそれに基づき部隊規模や経費などを明示する中期防衛力整備計画(中期防)の策定について、来年12月へ1年先送りを決定している。次期中期防には、F35の調達計画を明記する見通しだ。
 鳩山内閣は1年先送りに伴い、装備品や自衛隊の運用で暫定的な基本指針を取りまとめ、10年度予算にはFXの調査費だけを計上する予定。(共同)


---U.S. Says Lockheed Must Pay Part of F-35 Cost Overruns---
By CHRISTOPHER DREW

WASHINGTON - The Pentagon’s top acquisition official said on Monday that Lockheed Martin, the prime contractor for the new F-35 fighter jet, would have to cover part of the increased costs of the huge program.

The official, Ashton B. Carter, an under secretary of defense, said he had delivered that message to the company’s chief executive, Robert J. Stevens, on Sunday at a meeting on how to get the program back on track.

The meeting was prompted by an internal Pentagon report suggesting that work on the new stealth fighter, the Pentagon’s largest weapons program, had fallen so far behind that it could cost $16.6 billion more than expected over the next few years.

Dr. Carter told reporters that the Pentagon might add more planes to the flight test program and encourage the company to hire more software engineers to finish the planes faster.

Lockheed Martin has described the latest Pentagon cost estimates as a worst case. It has said it is making manufacturing improvements that could keep the costs from ballooning and help it get back on schedule by 2011.

Dr. Carter said he wanted to make changes now to bolster the program, which could cost $300 billion for more than 2,400 planes, to be bought over 25 years.

Other officials have said that the Pentagon could add more than $200 million to the program’s budget for the 2011 fiscal year. Dr. Carter said it would make sense to invest more soon to try to head off some of the problems.

“I think both the government and Lockheed Martin should be prepared to share in that investment,” he said, adding that company officials had agreed to accept whatever plan emerged.

While many Pentagon programs have had worse delays and cost overruns, the problems on the F-35 have occurred as President Obama has promised to eliminate much of the waste in military programs.

At the Pentagon’s request, Lockheed Martin is already building some of the planes even though the flight test program is only 2 percent complete. That means costly modifications could be needed if problems are found.
