Departure of the KC-135 — March Air Reserve Base's 'airborne Shell station' — marks end of era
In service for six decades, the Air Force’s 396 KC-135s — March has 12 of them — are being phased out and replaced by the newer, more advanced Boeing KC-46A Pegasus. The U.S. military has ordered 179 KC-46As to be delivered between now and 2029.
