The Northern Fleet has completed a large-scale exercise in the Arctic Region.

Twelve successful launches of sea- and ground-based cruise missiles were made, RIA Novosti reported, citing Commodore Vadim Serga, the head of the Northern Fleet's press service.

During the exercise, the Northern Fleet joint strategic command forces performed various actions to defend the Russian Arctic coast and insular zone, simulating various cases of existing and potential threats.

"Major tasks practiced during the Arctic exercise were fighting off massive air strikes using live anti-aircraft missiles, conducting anti-assault actions using Arctic units combined with ship formations, and carrying out a powerful missile-firing exercise with sea- and ground-based cruise missiles," Commodore Serga said.

About 50 ships, submarines and other vessels were involved in the exercise, as well as over 10 airplanes and helicopters.
