The UH-1N aircraft initially provided search and rescue capabilities before replacing earlier Huey variants in the ICBM field security and support role. UH-1Ns also provide administrative/DV lift to U.S. National Rucker.
USAF modified single-engine UH-1H to become a dedicated TH-1H training variant, extending the airframes’ service lives by at least 20 years. USAF awarded Boeing the $2.4 billion UH-1N replacement contract for up to 84 MH-139s in 2018, but contract delays pushed initial fielding to 2023 or beyond.
The fleet is fully upgraded with NVG-compatible cockpits, sensors, and safety and sustainment improvements. The UH-1N is the only DOD aircraft fleet to consistently achieve its target mission capable rate over the past decade, and FY26 funds additional reliability enhancements.
USAF planned to begin retiring the fleet in 2022 with full retirement by 2032. Yokota retired its Hueys on Sept. 5, 2025, placing a single aircraft on permanent display on base.
