The U.S. Marine Corps has detailed how 3rd Marine Aircraft Wing used KC-130J Super Hercules aircraft to project F-35B Lightning II combat power across roughly 4,000 nautical miles of the Indo-Pacific during Operation Slingshot. The move showed how Marine aviation can sustain fifth-generation fighters through remote locations, with KC-130J crews acting as mobile logistics and refuelling nodes rather than relying solely on established bases or external strategic tankers.
The route ran from Royal Australian Air Force Base Tindal through northern Australia, Pacific islands and Hawaii, with KC-130Js moving ahead of the fighters to establish forward support points. The aircraft carried Marines, maintenance equipment, fuel and other mission-essential supplies, while MV-22B Ospreys helped secure operating sites along the way.
The 4,000-nautical-mile figure refers to the distance over which the Marines demonstrated force projection and sustainment, not the F-35B’s own combat radius. The operation highlighted the service’s distributed maritime operations concept, in which aviation can create temporary refuelling and rearming points in austere locations and keep combat aircraft dispersed, supported and harder to target across the Indo-Pacific.
