The Russian planes - Tupolev Tu-95 bombers and Su-35 fighters - were intercepted by US F-22 fighter jets as they entered the Alaskan Air Defense Identification Zone that extends about 200 miles off the state's western coast, NORAD said.
They were "positively identified" by a US E-3 spy plane that was conducting overall surveillance.
"The Russian bombers and fighters remained in international airspace and at no time did the aircraft enter United States or Canadian sovereign airspace," the statement said.
The Russian Defense Ministry confirmed the incident in a tweet Tuesday. It said:
Aerospace Forces "made scheduled sorties over the neutral waters of the Chukotka, Bering and Okhotsk seas, as well as along the western coast of Alaska and the northern coast of the Aleutian Islands. At certain stages of the route, Russian aircraft were escorted by #F22 fighter jets of the #USAF. The total flight time exceeded 12 hours."
