ST. GEORGE — Over the next three weeks, Southern Utah, southern Nevada and possibly the Arizona Strip between the two, may experience some reverberation as military exercises are underway at Nellis Air Force Base in Nevada. Beginning Tuesday GPS intervention testing commences in the same region intermittently over the same period, impacting aviation. Nevadans, in particular, may notice increased military aircraft activity.
Although Nellis AFB Senior Airman Timothy Young said Friday that he is unaware of any direct connection between the Air Force exercises and the GPS interference testing announced by the Federal Aviation Administration, FAA Spokesperson Laura Brown out of the District of Columbia said Monday that the military is conducting the GPS interference testing. She did not know, she said, if the GPS testing correlates to the Red Flag Exercises.
“We put out these notices when there is military testing going on,” Brown said, adding that the military does most of the GPS testing, specifically U.S. Stratcom, or strategic command.
Red Flag 15-3 exercises
Red Flag 15-3 is a realistic combat training exercise involving the air, space and cyber forces of the United States and its allies, according to a release issued by Nellis AFB. The exercise will be held July 13-31 on the Nevada Test and Training Range just north of Las Vegas.
Fourteen different types of aircraft and pilots from 18 squadrons representing 12 U.S. states and Germany will be participating in the drills.
More than 115 aircraft are scheduled to depart Nellis twice a day and may remain in the air for up to five hours. Flying times are scheduled to accommodate other flying missions at the base and provide Red Flag participants with valuable training in planning and executing a wide variety of combat missions.
The Nevada Test and Training Range is, according to Nellis AFB’s release, the U.S. Air Force’s premier military training area with more than 15,000 square miles of airspace and 2.9 million acres of land.
With 1,900 possible targets, realistic threat systems and an opposing enemy force that cannot be replicated anywhere else in the world, Nellis AFB and the Nevada Test and Training Range are the home of a simulated battlefield, providing combat air forces with the ability to train to fight together in a peacetime environment, and to survive and win together.
The 414th Combat Training Squadron is responsible for executing Red Flag. The exercise is one out of a series of advanced training programs administered at Nellis AFB and on the Nevada Test and Training Range by organizations assigned to the U.S. Air Force Warfare Center.
Aircraft and squadrons participating in July’s exercise are:
- 53rd Wing, 422nd Test and Evaluation Squadron, F-15Cs, Nellis AFB, Nevada
- 159th Fighter Wing, 122nd Fighter Squadron, F-15Cs, New Orleans, Louisiana

- 116th Air Control Wing, 16th Airborne Command and Control Squadron, E-8s, Robins AFB, Georgia
- 2nd Marine Aircraft Wing, Marine Fighter Attack Squadron 115, F/A-18s, Marine Corps Air Station Beaufort, South Carolina
- 2nd Marine Aircraft Wing, Marine Tactical Electronic Warfare Squadron 4, EA-6Bs, Marine Corps Air Station Cherry Point, North Carolina
- Commander, Electronic Attack Wing, Electronic Attack Squadron 138, EA- 18Gs, Naval Air Station Whidbey Island, Washington
Southern Utah residents have reported loud booms during previous Red Flag and other exercises undertaken at Nellis AFB. That said, planes from Red Flag do not fly as far as St. George, Young said, and will stay within the confines of the Nevada Test and Training Range.
GPS Interference Testing
An advisory to pilots issued by the Federal Aviation Administration Thursday, titled “GPS Interference Testing, NTTR 15-12” stated the testing will occur at specified times beginning Tuesday through the end of July.
“GPS testing is scheduled …,” the advisory to pilots stated, “and may result in unreliable or unavailable GPS signal.”
Brown said the GPS interference testing conducted by the military relates to aviation, explaining in simple terms that it uses certain areas of the spectrum and is unlikely to impact other users. It’s like listening to FM radio, she said, the band and frequency is different than AM radio. The frequencies affected by the GPS interference testing are aviation specific.
The scheduled GPS testing in the area includes two hours a day during several days for up to 400 nautical miles around Beatty, Nevada, or 117 nautical miles from St. George. (A nautical mile is equal to 1.1508 miles and is usually expressed in a line following the curve of the earth.)
More specifically, the GPS signal may not be available from 10:30 p.m. to 12:30 a.m. MDT on the following dates: July 14-17, July 21-25 and July 28-31.
According to the advisory, at 50 feet above ground level, the disruption could extend up to 206 nautical miles; and at 25,000 feet, the disruption could extend up to 366 nautical miles, extending into Mexican airspace.
