Russia will conduct its annual strategic nuclear exercise "Grom" just as NATO holds its own "Steadfast Noon" strategic nuclear drills.
While the location where the Grom will take place is currently unknown, NATO's Steadfast Noon exercise is set to take place some 600 miles away from Russia, according to US officials.
US officials have also said that Steadfast Noon, also an annual exercise, is not linked to tensions with Russia or other real-word events.
