Derived from the commercial DC-4 airliner, the C-54 Skymaster was a workhorse transport aircraft for both the United States Army and the United States Navy branches of service. Planned as a technologically superior successor to the DC-3 type, the early DC-4 design suffered through growing pains of burgeoning pressurization technology, proving too much to handle and well ahead of its time. As such, the DC-4 design went back to a simplified un-pressurized version that would become the basis for the C-54 for Army use and the R5D for Navy usage.
Design of the DC-4 type consisted primarily of a sleek fuselage and began as early as 1935, though production elements were not delivered till 1942. Even then, the early models destined for civilian transport use were rerouted and enlisted for military service. Four Pratt & Whitney brand radials were mounted on the low monoplane wing assembly. A single ventral vertical surface was set on the tail section in place of the twin fins found on the early DC-4E models. Crew accommodations amounted to 4, with seating for up to 86 civilian passengers and an additional four in-flight service crew.
The system saw extensive service for both US branches and appeared in a variety of forms, differing in powerplant usage and number of passenger seats. Some dedicated troop and cargo transports existed with US President Roosevelt's own VIP version known as the "Sacred Cow" - utilized as a personal transport throughout the war. Post war service amounted to high utilization during the Berlin Airlift as well as serving in further models as a civil passenger airliner in later years.
