 Advantages over the UH-1N include 30 percent more speed, range, and loiter time, enhanced reliability and crashworthiness, night vision compatibility, modern avionics, and being cheaper to operate.In August 2013, the USAF said it planned to sustain the UH-1N for six to ten more years.In September 2013, acting Air Force Secretary Eric Fanning received a letter from the CEO of EADS North America, arguing that to refit and maintain the Hueys costs more than to acquire and operate UH-72As; the letter also urged prompt action as Army orders were almost complete and production was winding down.
