Douglas C-54 Skymaster

Updated: October 2026 – When people in Germany say “Rosinenbomber” (raisin bomber, the Candy Bomber), they mostly mean this aircraft: the Douglas C-54 Skymaster. As the military version of the DC-4 it flew across oceans in World War II, carried the bulk of the American airlift to West Berlin in 1948/49 and even served as the first aircraft dedicated to a US President. This page is about the military Skymaster: its versions, its role over Berlin and the question of where you can still find a preserved or even airworthy C-54 today.

C-54 or DC-4: how the Skymaster came to be

Douglas had designed the DC-4 in the late 1930s as a four-engine successor to the Douglas DC-3 for the big US airlines. The orders were in, series production was just starting – then came the US entry into the war in December 1941. The government took over the aircraft that had actually been meant for scheduled service, and the airliner became a military transport. The first aircraft took off on February 14, 1942 in Santa Monica, straight away as a C-54.

The concept fit the needs of the US Army Air Forces perfectly: four reliable Pratt & Whitney R-2000 Twin Wasps, long range, a nosewheel landing gear for convenient loading and unloading, and a roomy, straight fuselage. There was no pressurized cabin, which was no problem for cargo and troop transport at medium altitudes. The US Navy ordered the same type under the designation R5D; in 1962 the military unified the names, and the Navy aircraft were called C-54 from then on as well.

Production took place not only in Santa Monica but also at a Douglas plant in Chicago. By the end of the war just over 1,160 military aircraft had been built. Because the military took practically the entire output, the Skymaster is not the exception but the normal case for the series: most DC-4s that flew with airlines after 1945 were converted C-54s. You can read more about the type’s civil career on the page about the Douglas DC-4.

The versions at a glance

For spotters who like to look at museum plaques and serial numbers, the sub-versions are worth a look. Externally they are hard to tell apart; the differences lie in tanks, floors, doors and engine variants.

Version	Built	Special feature
C-54	24	first series, taken directly from ongoing airliner production
C-54A (Navy: R5D-1)	252	reinforced airframe, more fuel, designed for cargo or passengers
C-54B	220	additional tanks in the wing, hence more room in the fuselage
C-54D	380	like the C-54B, but with a different R-2000 version; most built
C-54E	125	changed tank layout, faster to convert between cargo and passengers
C-54G	162	like the C-54E with a different engine variant; further orders canceled after the war

There were also one-offs and later conversions. The best known is the VC-54C, which we come to shortly. After the war, special versions were also made from existing airframes, for example for rescue missions, surveying or as test beds. You usually only recognize these conversions from museum information, because the basic shape always stayed the same.

Incidentally, a special C-54B example was used by British Prime Minister Winston Churchill. Even during the war, the Skymaster was thus the aircraft of choice when high-ranking passengers had to travel safely over long distances.

The “Sacred Cow”: the first presidential aircraft

A single VC-54C was built for President Franklin D. Roosevelt, heavily modified already on the assembly line. The key detail: a battery-powered elevator at the tail that let Roosevelt board in his wheelchair. Because of the strict security around the aircraft, it soon got the nickname “Sacred Cow.”

Roosevelt flew it just once: in February 1945 to the Yalta Conference. A few weeks later he died. His successor Harry S. Truman kept using the aircraft and in 1947 signed the National Security Act aboard, which made the US Air Force an independent branch of the armed forces. The Sacred Cow is therefore considered the direct ancestor of all later “Air Force One” aircraft.

Today the VC-54C stands restored in the National Museum of the US Air Force in Dayton. If you are there, take a look at the tail: the elevator cabin is the clearest feature that sets it apart from every other C-54.

Backbone of the Berlin Airlift

From June 24, 1948, the Soviet Union closed all land and water routes to West Berlin. The Western Allies responded by supplying the city by air. The whole political story is in the article on the Berlin Airlift – here the focus is the role of the C-54.

At first the Americans flew mostly the smaller C-47, the military version of the DC-3. It quickly became clear that the bottleneck was not the aircraft but landings and unloading times in Berlin. Every landing therefore had to bring as much cargo as possible. A C-54 managed about ten tons, a C-47 only a little over a third of that. The US Air Force then pulled Skymasters together from around the world, and the US Navy contributed its R5Ds. In total, more than 300 C-54s and R5Ds took part in the American share of the airlift.

Under General William H. Tunner, operations became precision work. The aircraft flew at fixed altitudes and intervals through three air corridors, inbound and outbound flights were separated, and anyone who missed the landing in Berlin flew back with no second attempt. The high point was the so-called “Easter Parade” at Easter 1949: within 24 hours the Allies, according to the US Air Force, brought 12,941 tons to Berlin. The C-54 was the workhorse that made this rhythm possible in the first place.

Destinations in Berlin were Tempelhof Airport, the British airfield Gatow and Tegel, built in a hurry during the blockade. Flights departed from western Germany, mainly from Rhein-Main near Frankfurt and Wiesbaden. The blockade ended on May 12, 1949, and for safety the flights continued until September 30, 1949. How Tempelhof Airport changed during this time is told in the history of Tempelhof Airport.

Why “Rosinenbomber”?

The airlift owes the nickname above all to pilots like Gail Halvorsen, who on approach to Tempelhof dropped candy on tiny handkerchief parachutes for the waiting children. “Candy Bomber” became “Rosinenbomber” (raisin bomber) in German. The name sticks to all airlift aircraft, including the C-47 and British types – but in everyday talk most Berliners think of the four-engine Skymaster.

After Berlin: Korea, MATS and the long end

The C-54 stayed in service after the airlift as well. In the Korean War from 1950 it was initially the most important transport for supplies across the Pacific and within the war zone. Many aircraft flew with the Military Air Transport Service (MATS), whose silver paint scheme some museum aircraft wear again today.

With larger types like the Douglas C-124 and later the turboprop and jet transports, the Skymaster lost its leading role. But it was long from disappearing entirely: the US Air Force used the C-54 until 1972, and the last active aircraft of the US Navy was retired on April 2, 1974. Numerous other air forces, including the French Air Force, also used the type.

In parallel, retired Skymasters moved on to civil operators – as cargo and charter aircraft, later also as firefighting aircraft. Among the early airline customers for converted aircraft were Pan Am, Swissair and Balair. The direct successors in the same company were the pressurized Douglas DC-6 and the DC-7.

How to recognize a C-54

For a four-engine vintage aircraft, the Skymaster is pleasantly distinctive. It is best to proceed in three steps:

A useful detail on the ground is the large cargo door behind the wing on the left side. On aircraft converted to passenger service after the war, it may be sealed or covered – then only the registration history helps. For how to tell it from other military transports, see the guide Identifying military transports; general tips on vintage aircraft are at Identifying historic aircraft.

Feature	C-47 / DC-3	C-54 / DC-4	DC-6	L-1049 Super Constellation
Engines	2	4	4	4
Landing gear	Tailwheel	Nosewheel	Nosewheel	Nosewheel
Tail	single	single, tall	single, tall	triple
Windows	square	round	square	round
Fuselage	short, straight	straight, cylindrical	longer, straight	curved

You can reliably rule out the Super Constellation by its triple tail; more on the page about the Lockheed L-1049 Super Constellation.

Preserved C-54s in Germany

In Germany you practically no longer see Skymasters flying. But there are two very good addresses on the ground – both at places directly connected to the airlift.

Frankfurt, Airlift Memorial: At the edge of Frankfurt Airport, on the grounds of the former Rhein-Main Air Base, a C-47 and a C-54G (serial number 44-9063) stand side by side. The Skymaster stands in for all the aircraft that flew from here to Berlin. The trip combines well with a visit to the Zeppelinheim viewing platform.

Berlin, Tempelhof: The German Museum of Technology Berlin keeps a 1945 C-54 on long-term loan in the hangars of the decommissioned Tempelhof Airport – together with an Ilyushin Il-14P and a reconstructed Focke-Wulf Fw 200 “Condor,” both restored by volunteers. You can see the Skymaster on guided tours at the airport; find dates directly at Tempelhof Airport. A Candy Bomber could hardly stand more impressively than where the airlift aircraft landed more than 75 years ago.

Also worthwhile for the topic is the Military History Museum Berlin-Gatow Airfield, because Gatow was the British destination airfield of the airlift. Which aircraft are on show there at the moment is best checked before your visit.

Museum aircraft in Europe and the US

Outside Germany the list is longer. A selection worth a trip:

Place	Example	Note
Aviodrome Lelystad, Netherlands	C-54A (ex 42-107469)	in the livery of KLM DC-4 PH-TAR, which in 1946 flew from Amsterdam to New York as the first scheduled airliner of a European airline
National Museum of the US Air Force, Dayton	VC-54C “Sacred Cow”	the first presidential aircraft, restored
Pima Air & Space Museum, Tucson	C-54D (42-72488)	owned by the National Museum of the US Air Force, in the outdoor area

C-54s also stand in museums in Turkey, South Korea, Saudi Arabia and Venezuela, among others, as well as at more places in the US. In outdoor areas especially, paint and placement change occasionally – plan with the current status of the respective museum.

Airworthy Skymasters: the last of their kind

Seeing a C-54 in the air is real luck today. The best known is the “Spirit of Freedom” of the Berlin Airlift Historical Foundation in the US, a flying museum of the airlift. Its story has a twist: the foundation’s original aircraft, a C-54E, was badly damaged by a tornado in Walterboro, South Carolina, in April 2020. Instead of years of repairs, the foundation bought another Skymaster – the C-54D 43-17228, which went to the US Air Force in 1945 and itself flew supply missions for the airlift between October 1948 and May 1949.

Later, exactly this aircraft flew as a firefighting aircraft, among other things. In April 2021 it took off for the first time under the foundation’s direction, took over parts such as propellers and cockpit components from the damaged predecessor and received the foundation’s colors in fall 2021. Since then it has appeared at airshows and events in the US. A genuine airlift veteran, flying again.

Further airworthy Skymasters and DC-4s exist only sporadically, mostly with small cargo or collector operations, mainly in North America. Whether a particular aircraft is flying at the moment changes from season to season.

Tips for photos and visits

Whether in the hangar at Tempelhof or at an airshow in the US: with a little preparation you get more out of the rare encounter.

• On the ground: In halls the light is often weak. A fast wide-angle lens helps to fit the 35.8-meter wingspan into the picture at all. Plan detail shots of radial engines, nosewheel, cargo door and serial number – they document the identifying features better than any overall view.
• In the air: For spinning propellers you need a rather long shutter speed and clean panning. The guide Photographing propellers shows how it works.
• At airshows: Packing list and choice of location are explained in the article Photographing airshows. Many vintage aircraft meetings such as the Hahnweide vintage aircraft meeting show rather smaller types – a C-54 there is the absolute exception.
• Document it: Note the serial number and post the sighting with photo and location. That way you build up your own little collection of vintage aircraft over time.

If you want to dive deeper, you will find many dedicated associations around historic aircraft – from restoration to guided tours. The article Volunteering in aviation museums describes how you can take part.

Conclusion

The C-54 Skymaster is the aircraft with which the DC-4 really made history. It carried troops and cargo across the oceans of World War II, brought a US President to Yalta and supplied an entire city over Berlin. Today it has become rare, but not vanished: in Frankfurt and Tempelhof you can look at it up close, and with some luck you can see a genuine airlift veteran in the air in the US.
