Ahead of Biden-Putin summit, Russia conducts what it calls its largest naval exercise in the Pacific since Cold War

The Russian Navy is conducting what Russian officials call its largest exercise in the Pacific Ocean since the end of the Cold War. The exercise, about 300-500 miles west of Hawaii, comes just ahead of the meeting between Russian President Vladimir Putin and U.S. President Joe Biden, their first since Mr. Biden took office in January. 

The exercise includes surface ships, anti-submarine aircraft and long range bombers.  U.S. defense officials said that on Sunday, the U.S. scrambled F-22s from Hawaii in response to the bomber flights, but the bombers did not enter the Air Defense Identification Zone and were not intercepted.
