イラン RQ170複製へ

イランはRQ170を複製するようだ。
 イランのファルス通信などによると、同国の精鋭部隊「革命防衛隊」の
アミールアリ・ハジザデ航空部隊司令官は、イランが昨年12月に撃墜、押収
したと発表した米軍の最新鋭無人偵察機「RQ170」について、機体と機内に
残された情報の解読に成功し、同機を模した無人偵察機の建造に乗り出した
ことを明らかにした。

イランは、パキスタンから得た遠心分離機を解析し、現在の核燃料濃縮技術
を確立。また、露、中国からのRQ170の解析結果提供依頼を断ったとのこと。
リバースエンジニアリングと言っても、物理的な装置の話。
映像やナビ、トラッキング等は衛星組込み技術のように、絶えず変更される
ため、不揮発性メモリに記録しないだろうし、HDDに記録されたデータに
意味があるかは不明。
ステルス機能の形状や塗料、映像での光学的技術、航空機器が得られた情報
だろう。
完全複製ができれば、CIAが米国領土へナビ情報を与えて戻すだろう。
その前に、複製機は飛ぶことができるのか。

 【テヘラン=五十嵐弘一】イランのファルス通信などによると、同国の精鋭部隊「革命防衛隊」のアミールアリ・ハジザデ航空部隊司令官は22日、イランが昨年12月に撃墜、押収したと発表した米軍の最新鋭無人偵察機「RQ170」について、機体と機内に残された情報の解読に成功し、同機を模した無人偵察機の建造に乗り出したことを明らかにした。
 これが事実とすると、米軍の先端技術情報が、核問題などで対立を深めるイランに流出したことになる。
 同司令官によると、この機体が、国際テロ組織「アル・カーイダ」指導者のウサマ・ビンラーディンが潜伏していたパキスタンの施設上空を、昨年5月に行われた殺害作戦の2週間前に飛行していたことも、解読の結果、つかんだという。

 テヘラン(CNN) イランは22日、同国が昨年12月に回収したとする米国の無人偵察機について、システムの暗号を解読し、情報を引き出すことに成功したと発表した。同国のファルス通信が伝えた。
 ファルス通信によると、イラン革命防衛隊の空軍司令官は「われわれがこの無人偵察機の情報システムと端末にどれほど深く侵入できるかを米国人に知らしめる」と述べ、同機の記憶装置から引き出した情報として、パキスタンに潜伏していたアルカイダ指導者のオサマ・ビンラディン容疑者が昨年5月に殺害される2週間前、同機が潜伏地の上空を飛行していたことが分かったと発表。さらに、修理や出動の記録についても暗号を解読できたと述べた。
 同司令官は、「我々がもし無人偵察機のソフトウエアとHDDにアクセスできていなければ、こうした情報を入手することはできなかった」と強調している。イラン軍は、米国防総省がイランの暗号解読能力について疑問に思っていたと捉えており、今回の発表は米国に解読の証拠を見せつける意味合いがある。
 米政府は22日の時点で、この発表についてコメントしていない。
 オバマ大統領は昨年12月の時点で、イランに対して無人偵察機の返還を求めたことを明らかにしていた。米当局者は、同機がアフガニスタン駐在の米中央情報局(CIA)と軍の関係者により情報収集活動に使われていたことを認めている。


---Iran claims captured U.S. drone was used to spy on Osama Bin Laden weeks before he was killed---
American officials have said little about the history of the particular aircraft

TEHRAN, Iran - Iran claimed Sunday that it had recovered data from an American spy drone that went down in Iran last year, including information that the aircraft was used to spy on Osama Bin Laden weeks before he was killed. Iran also said it was building a copy of the drone.

Similar unmanned surveillance planes have been used in Afghanistan for years and kept watch on Bin Laden's compound in Pakistan. But U.S. officials have said little about the history of the particular aircraft now in Iran's possession.

Tehran, which has also been known to exaggerate its military and technological prowess, says it brought down the RQ-170 Sentinel, a top-secret drone equipped with stealth technology, and has flaunted the capture as a victory for Iran and a defeat for the United States.

The U.S. says the drone malfunctioned and downplayed any suggestion that Iran could mine the aircraft for sensitive information because of measures taken to limit the intelligence value of drones operating over hostile territory.

The drone went down in December in eastern Iran and was recovered by Iran almost completely intact. After initially saying only that a drone had been lost near the Afghan-Iran border, American officials eventually confirmed the plane was monitoring Iran's military and nuclear facilities.

Washington has asked for it back, a request Iran rejected.

The chief of the aerospace division of the powerful Revolutionary Guards, Gen. Amir Ali Hajizadeh, told state television that the captured drone is a "national asset" for Iran and that he could not reveal full technical details.

But he did provide some samples of the data that he claimed Iranian experts had recovered from the aircraft, state television reported.

"There is almost no part hidden to us in this aircraft. We recovered part of the data that had been erased. There were many codes and characters. But we deciphered them by the grace of God," Hajizadeh said.

Among the drone's past missions, he said, was surveillance of the compound in northwest Pakistan where Bin Laden lived. Hajizadeh claimed the drone flew over bin Laden's compound two weeks before the Al Qaeda leader was killed there in May 2011 by U.S. Navy SEALs.

He also listed tests and maintenance that the drone had undergone, all of which, he said, had been recorded in the aircraft's memory. According to Hajizadeh, the drone was taken to California on Oct. 16, 2010, for "technical work" and then to Kandahar, Afghanistan, on Nov. 18, 2010.

He said it carried out flights from Afghanistan but ran into some problems that U.S. experts were unable to fix. Then the drone was taken in December 2010 to Los Angeles, where the aircraft's sensors underwent testing, Hajizadeh said.

"If we had not achieved access to software and hardware of this aircraft, we would be unable to get these details. Our experts are fully dominant over sections and programs of this plane," he said.

Hajizadeh said he provided the details to prove to the Americans "how far we've penetrated into this aircraft."

The U.S. Defense Department said it does not discuss intelligence matters and would not comment on the Iranian claims.

The semiofficial Mehr news agency said Iran had reverse-engineered the aircraft and has begun using that knowledge to build a copy of the drone.

Sen. Joe Lieberman, an independent from Connecticut who chairs the Senate Homeland Security and Governmental Affairs Committee, said on "Fox News Sunday" that he views the reports with skepticism.

"There is a history here of Iranian bluster, particularly, now when they are on the defensive because of the economic sanctions against them."

He acknowledged that it was "not good for the U.S. when the drone went down in Iran and not good when the Iranians grabbed it." But the senator said he did not "have confidence at this point that they are really able to make a copy of it."

Iran has gone a long way in reverse-engineering some key technologies in the past three decades, particularly in the areas of nuclear and missile technology.

Iran's famous Shahab-3 missile, first displayed in 1998, is believed to be based on North Korea's Nodong-1 design. Iran obtained its first centrifuge from Pakistan in 1986 and later reverse-engineered it to develop its now advanced uranium-enrichment program.

Centrifuges, which purify uranium gas, are the central component of a process that can make fuel for power plants or - at higher levels of processing - weapons.

However, unlike the situation with the drone, the Iranian government usually touts these achievements as the result of an indigenous, home-grown research.

One area where there is concern is whether Iran or other states could reverse-engineer the chemical composition of the drone's radar-deflecting paint or the aircraft's sophisticated optics technology that allows operators to positively identify terror suspects from tens of thousands of feet in the air.

How much data there is on the drone is another question. Some surveillance technologies allow video to stream through to operators on the ground but do not store much collected data. If they do, it is encrypted.

Media reports claimed this week that Russia and China have asked Tehran to provide them with information on the drone, but Iran's Defense Ministry denied that.


---Iranians Say They Took Secret Data From Drone---

WASHINGTON - Iran claimed on Sunday to have extracted secret intelligence information from an advanced American drone aircraft that crashed in the country in December, seeking a propaganda victory over what has been an embarrassing intelligence failure for the Central Intelligence Agency.

The air force commander of Iran’s Revolutionary Guards, Brig. Gen. Amir Ali Hajizadeh, suggested in remarks to the country’s semiofficial news agency that Iran had or would soon reverse-engineer the aircraft, known as the RQ-170 Sentinel, though American intelligence officials and experts have discounted the country’s ability to do so.

General Hajizadeh cited as evidence data that he said was extracted from the drone’s computer hard drives revealing its operations in the months before it went down in Iran - either because it was shot down, as Iranian officials have claimed, or because it experienced a technical failure, as the Americans have said.

The drone, he said, had undergone repairs in California in October 2010 and returned to Afghanistan in November 2010, where American officials have acknowledged it operated, though without specifying where its missions took it. He added that the drone’s computer memory revealed that it had flown over the compound in Pakistan where Osama bin Laden was killed in an American raid in May 2011.

“Had we not accessed the plane’s softwares and hard disks, we wouldn’t have been able to achieve these facts,” General Hajizadeh said, according to the news agency Fars.

The White House and American intelligence officials declined Sunday to comment on the new claims, though independent experts expressed skepticism. They noted that the information about the drone’s activities - including its use in the Bin Laden raid - could have been drawn from public reports about the sophisticated aircraft. It was not clear what record of previous flights would have remained on the drone’s systems.

Senator Joseph I. Lieberman, independent of Connecticut and a member of the Senate’s Armed Services Committee, also suggested that Iran’s claims were probably overblown, though he said the drone’s loss was embarrassing.

“I think there is a history here of Iranian bluster, particularly now when they are on the defensive because of our economic sanctions against them,” he said on “Fox News Sunday,” referring to the increasingly punitive restrictions on Iran’s oil industry and central bank imposed by the United States and Europe because of the country’s nuclear program. “But, look, it was not good for the U.S. when the drone went down in Iran, and not good when the Iranians grabbed it.”

Mr. Lieberman called the drone “a very sophisticated piece of machinery” that he assumed had operated in Iran, “particularly at areas where we have reason to believe that they are working on a nuclear weapon.”

American officials have said that the drone’s onboard computers were programmed to destroy important information if it stopped responding to radio signals from its base. They said, however, that such security systems do not always function properly and that intelligence and military officials of other countries, including China and Russia, would undoubtedly try to persuade Iran to share any data or allow their experts to study it.

Dennis M. Gormley, an expert on drones and cruise missiles at the University of Pittsburgh, said Sunday that Iran’s claims strained credibility. “It’s hard for me to imagine no self-destruct or erase mechanism was embedded in the drone to destroy sensitive systems, including software.”

He added: “As someone who does monitor Iranian aerospace and missile claims closely, let me simply observe that they are preternaturally disposed to exaggeration.”
