Russians have operated surveillance flights over Area 51 in southern Nevada.
Last week, a Tu-154M aircraft was captured flying over several military installations in the western US, reported The Drive.
The move is legal under the Treaty on Open Skies, which allows countries to monitor each other to collect data on military forces and activities.
the flight took place on Thursday, March 28, and began at Travis Air Force Base in northern California.
The plane next flew over Edwards Air Force Base in Kern County California; Fort Irwin National Training Center in San Bernardino County, California; and Creech Air Force Base in Clark County Nevada, data from FlightRadar24 showed.
Next, the aircraft flew near Yucca Flat, which is one of four major nuclear test regions, and other areas of the Nevada Test Site.
