U.S. Air Force U.S. defense officials say reports from Russia that an American MQ-5B drone was intercepted over Crimea and made an emergency landing there are false. Voice of Russia reported on Friday that “an American scout-attack drone was intercepted in the Crimean sky" and made an emergency landing after an electronic attack disrupted its computers.

“There is zero truth” to the reports, said a Department of Defense spokesperson reached by phone in Washington.

According to the Russian source, the drone, an MQ-5B, belonged, judging by its markings, to the 66th US Military Intelligence Brigade, based in Germany.

The drone was at a height of about 4,000 meters or about 13,000 feet, according to Voice of Russia, which said it was in the possession of “self-defense forces.” A call to the brigade’s German headquarters was answered by a serviceman who said the unit had no knowledge of anything of the sort happening.

The MQ-5B Hunter is a variant of the RQ-5, originally an Israeli design. Its maker, Northrop Grumman Corporation (NYSE:NOC), describes it as a "long endurance, medium altitude, multimission, tactical Unmanned Aircraft System (UAS) optimized to provide Army division and corps commanders with a dedicated Intelligence, Surveillance, and Reconnaissance (ISR) platform."

According to data from the manufacturer, the MQ-5B is seven meters (23 ft) long, with a maximum takeoff weight of about 900 kilograms (2,000 lbs). It can fly for as many as 21 hours at an altitude up to 5,500 m (18,000 ft) and carriers several sensors and communications devices, but is unarmed.
