The Troop Transport version of the Douglas C-47 Skytrain lacked the reinforced cargo floor, the large cargo door, and hoist attachment of the C-47 Skytrain. It was dedicated for the troop transport role and could carry 28 passengers in fixed metal seats arranged in rows in the former cargo space. This specialized troop variant was used in vast numbers in Europe. They towed gliders towards the drops zones and carried paratroopers at the same time. In the Pacific they transported soldier from and to the United States.
The specialized Douglas C-53 Skytrooper was built 221 times, the “C” version; C-53C Skytrooper, with larger access of the port-side was built 17 times.
