What Does HIFR Stand For?

HIFR stands for Hover Inflight Refueling

HIFR, or Hover Inflight Refueling, is a specialized aerial refueling technique that allows helicopters and other rotary-wing aircraft to receive fuel from a tanker while maintaining a stable hovering position. This method is particularly advantageous in combat and emergency operations, as it enables refueling in confined or hazardous environments where traditional ground-based refueling may not be feasible. HIFR enhances operational endurance and extends the range of rotary-wing missions without the need for landing.
