The US Forest Service, through the National Interagency Fire Center, ended military C-130 Modular Airborne Fire Fighting System, or MAFFS, operations on 5 September 2013. MAFFS aircraft and crews remain available for recall if the wildland fire situation dictates. The Forest Service said wildland fire activity had begun to moderate, and that, along with the increased availability of civilian air tankers, allowed the release of the military aircraft, their crews and ground support personnel. Since the year’s initial activation on 11 June, MAFFS crews flew 572 missions and made 535 drops releasing 1,375,981 gallons of Phos-Chek fire retardant. The activated crews fought fires in Idaho, Oregon, Wyoming, Colorado, Utah, Arizona, California, and Nevada.
