Such intercepts have happened about 60 times between 2007 and 2017, The New York Times reported previous year.
It's the second time this month a pair of Russian bombers flew near Alaska.
This is the second similar interception this month after American fighter jets briefly escorted Russian bombers west of Alaska on September 1.
"At no time did the aircraft enter United States or Canadian sovereign airspace", NORAD said.
NBC News points out that it's not uncommon for these events to occur, and Russian aircraft have been accused several times of violating the airspace of America's North Atlantic Treaty Organisation allies and flying dangerously close to us ships and aircraft in the Black Sea.
The US Air Force said on Wednesday that two of their fighter jets intercepted two Russian bombers near Alaska.
During the September 1 bomber incursion, the Tu-95s were not shadowed by Russian jets.
"NORAD, the joint US and Canadian command", employs a layered defense network of radars, satellites, as well as fighters to identify aircraft and determine the appropriate response", he added.
On May 11, USA jets shadowed a pair of Tu-95s as they flew in the zone, which extends 200 miles from the coast, in the Bering Sea north of the Aleutians.
Russian bombers in the past have conducted mock missile attacks against US missile defenses in Alaska.
Two Russian Tu-95 bombers were also intercepted by F-22's off the coast of Alaska in May, almost a year after the last encounter of this kind.
Earlier Wednesday, the Russian military released video on Twitter showing a pair of Cold War era Tu-95 "Bear" bombers and a pair of fighter jets taking off from an airbase in eastern Russia.
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.
