Iran military shoots down U.S. drone: state TV

(Reuters) - Iran's military said on Sunday it had shot down a U.S. reconnaissance drone aircraft in eastern Iran, a military source told state television.

"Iran's military has downed an intruding RQ-170 American drone in eastern Iran," Iran's Arabic-language Al Alam state television network quoted the unnamed source as saying.

"The spy drone, which has been downed with little damage, was seized by the Iranian armed forces."

Iran shot down the drone at a time when it is trying to contain foreign reaction to the storming of the British embassy in Tehran on Tuesday, shortly after London announced that it would impose sanctions on Iran's central bank in connection with Iran's controversial nuclear enrichment program.

Britain evacuated its diplomatic staff from Iran and expelled Iranian diplomats in London in retaliation, and several other EU members recalled their ambassadors from Tehran.

The attack dragged Iran's relations with Europe to a long-time low.

Washington and EU countries have been discussing measures to restrict Iran's oil exports since the United Nations nuclear watchdog issued a report in November with what it said was evidence that Tehran had worked on designing an atom bomb.

Iran says its nuclear program is entirely peaceful.

英国《飞行国际》2009年12月7日报道 洛克希德•马丁公司臭鼬工程队研制的隐身无人机系统已经秘密加入美国空军存货清单。

RQ-170是美国日渐庞大的大型监视无人机机队的新成员，该机队包括诺斯罗普•格鲁门公司的RQ-4“全球鹰”和通用原子航空系统公司的RQ-1“捕食者”/MQ-9“死神”。但是“哨兵”是首型正式承认的隐身设计作战无人机系统。

“哨兵”存在的证实还显示了洛克希德公司在大型无人机系统市场竞争的新亮点，在此之前该公司被认为没有研制该级别的产品。

洛克希德的“暗星”无人机在1990年代后期与“全球鹰”的竞争中落败。其后，洛克希德展示了P175“臭猫”，这是一种隐身高空无人机系统，目前唯一的消息是样机在一次试飞中坠毁。
