Overview
- Air Force Global Strike Command said the MH-139A reached initial operational capability on Aug. 10, 2026, meaning some units can employ and maintain the type for the ICBM security mission.
- The Grey Wolf is replacing the Vietnam-era UH-1N Huey for convoy escort and rapid response across the 20th Air Force’s roughly 33,600-square-mile missile fields.
- The jet‑turbine helicopter is nearly 50% faster than the Huey, can carry about twice as many troops, and adds upgraded defensive systems plus modern command‑and‑control avionics.
- The program’s path to IOC included FAA certification and testing delays, a 2024 cut in planned buys that triggered a Nunn-McCurdy cost breach, and a continued phased fleet buildout with multiple deliveries still pending.
- Operational use began earlier this year when two MH-139s escorted a Minuteman III convoy more than 100 miles on Jan. 8, 2026, and the service is activating squadron facilities to receive follow-on aircraft as the fleet grows.
