MH-139 Grey Wolf Reaches Initial Operational Capability

The Boeing-built helicopter is nearly 50% faster than the Huey and can carry twice as many troops, Air Force officials said.

  • On August 10, the U.S. Air Force reached initial operational capability with the MH-139A Grey Wolf, beginning replacement of aging UH-1N Hueys patrolling nuclear missile facilities.
  • Overseen by the 20th Air Force, the new aircraft supports missile field security across 33,600 square miles, replacing Vietnam-era platforms with enhanced defensive systems and speed to protect the Minuteman III ICBM.
  • The 582nd Helicopter Group spearheaded conversion training and testing, enabling the 40th Helicopter Squadron to conduct operational convoy escorts over 100 miles without refueling, fulfilling survivability requirements.
  • While designed for security missions, the MH-139 is no longer expected to transport VIP passengers; instead, the Air Force will utilize the Lockheed Martin-made HH-60W Jolly Green II at Joint Base Andrews.
  • As the Air Force prepares to transition from the Minuteman III to the LGM-35A Sentinel, the new helicopters are slated to support this security shift while performing search and rescue and medical evacuation tasks.
