In May 1983, the unit relocated to Stewart International Airport.
It was re-designated the 105th Military Airlift Group on 1 May 1984 and later in July 1985 became the first Air National Guard unit in the Nation to fly the C-5A Galaxy aircraft.
 Soon after receiving its first C-5A aircraft, in October 1985 the unit airlifted 84,600 pounds of cots and bedding to Puerto Rico following Hurricane Gloria.

In October 1988 the 105th airlifted 300,000 pounds of hurricane relief and reconstruction supplies to the island nation of Jamaica following Hurricane Gilbert.
In January 1989 the unit carried 146,610 pounds of earthquake relief supplies to aid Soviet Armenia.
In March 1989 the 105th responded with less than 24 hours notice to an AMC request to airlift an over 80,000 pound submersible vehicle from Andrews AFB, Maryland and Homestead AFB, Florida to Kadena AB, Japan to assist in search and recovery operations for an Air Force Sikorsky SH-3 Sea King helicopter which crashed in the East China Sea.
Throughout the summer and fall of 1989 the 105th continued to support reconstruction efforts in Jamaica by airlifting National Guard civil engineering teams and equipment to that island nation.

Beginning in October 1989 the unit airlifted over 2,000,000 pounds of relief supplies to Puerto Rico and the Virgin Islands following Hurricane Hugo.
In December 1991 the 105th airlifted over 145,000 pounds of clothing, blankets and medical supplies to Bucharest, Romania.
In February 1992 the unit participated in Operation Provide Hope, the airlift of humanitarian aid to the Commonwealth of Independent States (former Soviet Union); delivering 384,000 pounds of relief materials to Saint Petersburg, Russia and Yerevan, Armenia.

1989 ended on a dramatic note for the 105th Airlift Wing as it performed its wartime mission in support of Operation Just Cause.
The over 2,200,000 pounds of cargo airlifted by the 105th in support of that operation represented approximately 25% of the initial total airlift effort of all of the Military Airlift Command's C-5 fleet assigned to both active duty and reserve component elements.

On 7 August 1990 Governor Mario Cuomo announced that the Department of Defense had requested, and he had approved, the participation of the personnel and C-5A aircraft of the 105th in active and direct support of Operation Desert Shield in the Persian Gulf region.
On 24 August the 137th Military Airlift Squadron was called to active duty by President George H. W. Bush to provide continued support for this operation.
While the 137th was formally returned to state control on 15 May 1991, the majority of unit members chose to remain in active status until 1 August 1991 in response to the Military Airlift Command's need for continuing airlift support of Operation Desert Storm and Operation Provide Comfort (Kurdish relief).

On 28 February 1991, a part of the 105th USAF Clinic was also called to active duty with duty stations at Malcolm Grow Medical Center, Andrews AFB, Maryland.
All medical personnel were released from active duty during May 1991.

In March 1992, with the end of the Cold War, the 105th adopted the Air Force Objective Organization plan, and the unit was re-designated as the 105th Airlift Group.
On 1 October 1995, in accordance with the Air Force "One Base – One Wing" policy, the 105th Airlift Wing was established and the 137th Airlift Squadron was assigned to the new 105th Operations Group.

In September 1992 the unit responded to Hurricane Andrew; delivering 1,289,953 pounds of food, tents, mobile kitchens, vehicles, and emergency services personnel to the Homestead area of South Florida.
In November 1992 the 105th airlifted 118,450 pounds—including generators, portable shelters and medical supplies and equipment—to Zagreb, Croatia to support the U.S. Army's 212th Mobile Army Surgical Hospital's establishment of a facility to provide a full range of health care for United Nations forces deployed in Croatia and Bosnia-Herzegovina.
From December 1992 to April 1993 the 105th supported Operation Restore Hope providing humanitarian
