A fleet of fully armed aircraft from the 18th Wing conduct an elephant walk during a no-notice exercise April 12, 2017, at Kadena Air Base in Okinawa, Japan.
The 18th Wing operates combat ready fleets of HH-60 Pave Hawks, F-15 Eagles, E-3 Sentries and KC-135 Stratotankers, making it the largest combat-ready wing in the U.S. Air Force.
An elephant walk is a USAF term for the taxiing of military aircraft right before takeoff, when they are in close formation. Often, it takes place right before a Minimum Interval Takeoff.
This exercise is meant as a show of force in the Pacific theater.
