On Tuesday, NATO kicks off its annual anti-submarine exercise Dynamic Mongoose in the Norwegian Sea west of Andøya, northern Norway.

Six frigates, 10 aircraft and several submarines from Canada, the United States, France, Germany, Poland, Spain, Turkey and the United Kingdom, as well as host nation Norway, will participate in the drill that will last until July 14.

Among them are ships from NATO’s Standing Maritime Group One (SNMG1), which is sailing north directly after completing the annual Baltic Operations (BALTOPS). The navy group consists of U.S. flagship guided-missile destroyer USS Gravely, British frigate HMS Westminster and Turkish frigate TCG Gokova, NATO said.

While NATO is preparing the anti-submarine warfare exercises, Russia's Northern Fleet submarine Vladikavkaz has sailed out from Polyarny on the Kola Peninsula and is right now en route south toward St. Petersburg where it will take part in the annual naval parade.
