Air Force’s MH-139A Flies First Operational ICBM Convoy Escort

Initial operational capability is targeted for mid-April 2026, a schedule contingent on maintenance rates, UH-1N divestment.

Overview

  • Two MH-139A Grey Wolf helicopters from the 40th Helicopter Squadron escorted a Minuteman III convoy out of Malmstrom AFB on Jan. 8, flying about 100 miles out and back during a six-hour mission.
  • The aircraft completed the operation without refueling and outperformed the UH-1N with faster transit and greater lift, including roughly 50% higher speed and capacity for twice as many troops, according to base officials.
  • Air Force leaders called the mission a major step for nuclear security operations, citing improved range, lift, defensive systems, and crew situational awareness from upgraded sensors and avionics.
  • Initial operational test and evaluation has concluded, and the Air Force projects IOC for the Grey Wolf around mid-April 2026, with the timeline subject to maintenance performance and retirement of legacy Hueys.
  • Additional helicopters are being staged for other missile fields, including three destined for F.E. Warren AFB that are temporarily at Malmstrom as Minot AFB prepares to receive aircraft.
