The Russian warplanes did not enter US or Canadian sovereign airspace, the statement added.
They were intercepted by a pair of Air Force F-22 stealth fighter jets, according to a statement by the North American Aerospace Defence Command (NORAD).
Two Russian bombers were intercepted by two U.S. F-22 fighter jets near Alaska on Tuesday, said the USA military on Wednesday.
A similar incident occurred on September 1, the Washington Free Beacon first reported.
NORAD, however, released a photo of an F-22 flying close to one of the Russian bombers. However, defense officials said the bombers in that flight were supported by aerial refueling tankers. It added that the intercept took place while the Russian bombers were in the US Air Defense Identification Zone, which extends about 200 miles off Alaska's western coast.
It's the second time this month a pair of Russian bombers flew near Alaska.
They did not fly into USA or Canadian airspace.
Terrance O'Shaughnessy says radar, satellites and fighter jets are used to identify aircraft and determine appropriate responses.
No other details of the intercept were disclosed.
Two U.S. F-22 Raptor fighters met them in worldwide airspace west of Alaska around 10 p.m. Tuesday, NORAD said. The Russian planes did not enter sovereign USA airspace on either of the previous two occasions.
The maneuvers come as Russian forces participate in what The Associated Press reported is the nation's largest-ever military exercise.
The bombers were accompanied by Su-35s and refueling tankers and originated from a base in the Russian Far East, the Russian Defense Ministry said.
The drills involve almost 300,000 Russian troops along with 1,000 Russian aircraft, 36,000 tanks and other combat vehicles, the news agency said.
