MOSCOW, June 17. /TASS/. The Tachyon and Aileron-3 drones have been put on patrolling mission in the Arctic, spokesman for the Russian Northern Fleet Captain 1st Rank Vadim Serga said on Wednesday.

"The Tachyon and Aileron-3 unmanned aerial reconnaissance and surveillance complexes got off the ground into the Arctic sky," he said.

Serga said that the Arctic brigade’s drone unit was formed at the end of 2014. It is manned exclusively with contract personnel, the spokesman said.

The drones that have been brought into service with the Northern Fleet’s coastal defence troops, are designed for reconnaissance missions and are capable of flying at distances from 10 to 150 kilometres depending on the modification. The drones are capable of transmitting videos to the operator in the daytime and at during the night.

The Tachyon drone model has already been tested by motorized infantry troops of the coastal defence forces of the Northern Fleet in the Arctic conditions — in particular, the tests took place on the Franz Josef Land in mid-May.
