The Boeing Company began flight testing its new KC-46 Pegasus refueling aircraft in 2016. The KC-46 Pegasus is a wide-body, multi-role tanker that can refuel all U.S., allied, and coalition military aircraft compatible with international aerial refueling procedures.

This testing will continue throughout 2018.

Boeing is taking steps to minimize impacts on airport neighbors and routinely complies with all federal, state, county, and city codes, including the Boeing Quiet Hour procedures and the King County International Airport Fly Quiet Program.

We’ll provide updates on KC-46 flight test program changes as information from Boeing becomes available. King County does not have authority over military operations but works with Boeing to minimize the noise impacts.

King County International Airport, also known as Boeing Field, is one of the nation’s busiest primary non-hub airports. We average around 200,000 operations (takeoffs and landings) each year, and support $3.5 billion in local business sales. These in turn support 16,336 jobs and create $1.8 billion in labor income in King County. Our 150 tenant businesses directly support 5,209 jobs in the local economy. For details, see our 2013 economic impact study.

The airport serves small commercial passenger airlines, cargo carriers, private aircraft owners, helicopters, corporate jets, and military and other aircraft. It’s also home to various Boeing Company operations as well as the Museum of Flight. Thanks to our location just four miles south of downtown Seattle and close to other business centers, we frequently host celebrities and dignitaries, including the President of the United States.
