It was called to active duty in March 1951 for the Korean War, serving at its home station, Miami International Airport.

The group flew its first combat missions on D-Day by dropping paratroopers of 101st Airborne Division near Cherbourg Naval Base.

[1] The group began transport services following the landings in France and intermittently engaged in missions of this type until V-E Day In these operations the 435th hauled supplies such as serum, blood plasma, radar sets, clothing, rations, and ammunition.

[7] The detachment dropped paratroopers over the assault area on 15 August and also released gliders carrying troops and equipment such as jeeps, guns, and ammunition.

The following day it flew a resupply mission over France, then transported supplies to bases in Italy before returning to England at the end of the month.

[1] During the Battle of the Bulge, the group delivered supplies to isolated combat positions of the 101st Airborne and 7th Armored Divisions in Bastogne and Marcouray, Belgium.

[8] The unit moved to Bretigny Airfield, France in February 1945 to prepare for Operation Varsity, the airborne assault across the Rhine River.

Each group aircraft participating in this operation towed two gliders transporting troops and equipment to the east bank of the Rhine near Wesel on 24 March.

[1] The group transported supplies to occupation forces in Germany and evacuated Allied prisoners of war after V-E Day.

[11] Reserve flying operations at Morrison came to an end, with the exception of the 326th Troop Carrier Squadron, which remained there until September, when it moved to Pennsylvania and was assigned to another wing.

Although it remained at Miami, the group deployed twice while on active duty: to Laurinburg-Maxton Airport, North Carolina from 21 July until 1 September 1951 and to Grenier Air Force Base, New Hampshire from 2 January to 3 March 1952.

[17][18] The group was activated as a reserve unit the same day at the same station, but with the personnel and equipment of the inactivating 482d Troop Carrier Wing.

The squadron's stay in the Tampa Bay area was brief, however, for in November 1957 it moved again, this time to New Orleans Naval Air Station, Louisiana.

[23] This assignment was short-lived, for the reorganization of airlift in Europe included the establishment of a permanent C-130 squadron to replace the rotational units at Mildenhall.
