Russia's Federal Agency for Special Construction is expected to deliver over 300,000 tons of cargo to the Arctic, which is double the amount of materials and equipment sent up in 2014-2015, Interfax news agency reports.

"Efforts to equip Defense Ministry Arctic units will carry on until 2020," the agency said in a statement, as reported by Interfax. The shipments are consolidated at the ports of Arkhangelsk, Murmansk and Kandalaksha.

"More than 10 vessels capable of navigating the extremely difficult Arctic sea routes will deliver freight to military infrastructure construction sites in these remote territories," the Federal Agency for Special Construction said, adding that "a complex logistics system is used to build structures on Arctic islands since everything has to be delivered from the mainland."

According to the Federal Agency for Special Construction, its Second Engineering Division is working on six Arctic islands. In 2014, the division completed the construction of Defense Ministry facilities on Wrangel Island, Alexandra Land, and the Mys Shmidta and Novosibirskiye (New Siberian) islands. Russian service personnel have now been deployed to these locations.
