Design and development

The C-47 differed from the civilian DC-3 in numerous modifications that included being fitted with a cargo door and strengthened floor.

During World War II, the armed forces of many countries used the C-47 and modified DC-3s for the transport of troops, cargo and wounded. The US Naval designation was R4D. Over 10,000 aircraft were produced in Long Beach

Super DC-3 (R4D-8)

In response to proposed changes to the airworthiness requirements that would limit the continuing use of the large numbers of DC-3s and surplus C-47s in commercial use in the United States, Douglas offered a late 1940s conversion of the DC-3 modified to improve takeoff and single-engined performance to meet the new Civil Air Regulations

It also had larger tail surfaces and new outer wings with a greater sweep back at the trailing edge to accommodate a rearward shift in the center of gravity.

s incorporated into larger engine nacelles, were installed along with shorter, jet ejection-type exhaust stacks. Minor changes included wheel well doors and a partially retractable tail wheel along with flush rivets and low drag antennas, that all contributed to a top speed of 250 mph. With over 75% of the original DC-3/C-47 configuration changed, the modified design ended up virtually as a new aircraft. The first DC-3S made its maiden flight on 23 June 1949.

Although the changes fully met the new FAR 4B airworthiness requirements, and significantly improved performance, there was little interest from commercial operators in the DC-3S, which was too-expensive for the smaller operators who were its main target, with only three being sold to Capital Airlines
