, but was not as extensively produced.

After World War II, a few surplus C-46 aircraft were briefly used in their original role as passenger airliners, but the glut of surplus C-47s dominated the marketplace with the C-46 soon relegated to primarily cargo duty. The type continued in U.S. Air Force service in a secondary role until 1968. However, the C-46 continues in operation as a rugged cargo transport for Arctic and remote locations with its service life extended into the 21st century.

Design and development

The prototype for what would become the C-46, the Curtiss CW-20, was designed in 1937 by George A. Page Jr., the chief aircraft designer at Curtiss-Wright

 airliners. The CW-20 had a patented fuselage conventionally referred to as a "figure-eight" (or "double-bubble") which enabled it to better withstand the pressure differential at high altitudes. This was done by having the sides of the fuselage creased at the level of the floor that not only separated the two portions but shared in the stress of each, rather than just supporting itself. The main spar of the wing could pass through the bottom section which was mainly intended for cargo without intruding on the passenger upper compartment. A decision to utilize a twin-engine design instead of a four-engine configuration was considered viable if sufficiently powerful engines were available, allowing for lower operating costs and a less complex structure.

Engineering work involved a three-year commitment from the company and incorporated an extensive amount of wind tunnel testing at the California Institute of Technology

 (Caltech). The resultant design was a large but aerodynamically "sleek" airliner, incorporating the cockpit in a streamlined glazed "dome." The engines featured a unique nacelle "tunnel cowl" where air was ducted in and expelled through the bottom of the cowl, reducing turbulent airflow and induced drag across the upper wing surface. After a mock-up was constructed in 1938, Curtiss-Wright exhibited the innovative project as a display in the 1939 New York World's Fair

.

Although the company had approached many airlines in order to obtain their requirements for an advanced airliner, no firm orders resulted, although 25 letters of intent were received, sufficient to undertake production. The design of a 24-34 passenger airliner proceeded to prototype stage as the CW-20 at the St. Louis, Missouri facility with the initial configuration featuring twin vertical tail surfaces.

 became interested in the potential of the airliner as a military cargo transport, and on 13 September 1940, ordered 46 modified CW-20As as the C-46-CU Commando; the last 21 aircraft in this order were delivered as Model CW-20Bs, designated C-46A-1-CU. None of the first C-46s purchased by the U.S. military were pressurized. The design was then modified to the C-46A configuration, receiving enlarged cargo doors, a strengthened load floor, and a convertible cabin that speeded changes in carrying freight and troops. The C-46 was introduced to the public at a ceremony in May 1942, attended by its designer, George A. Page Jr.

A total of 200 C-46As in two initial batches were ordered. At this time, one other important change was made; more powerful 2,000 hp Pratt & Whitney R-2800

s. A number of minor modifications, such as fuel system changes and fewer cabin windows were also adopted. Subsequent military contracts for the C-46A extended the production run to 1,454 examples, 40 of which were destined for the U.S. Marine Corps, to be designated R5C-1. The military model was fitted with double cargo doors, a strengthened floor and hydraulically operated cargo handling winch; 40 folding seats were the sole passenger accommodation for what was essentially a cargo hauler. Tests indicated that the production C-46 was capable of carrying a substantial payload, and could fly well on one engine. When empty, the aircraft could even climb on one engine at 200–300 ft per minute.

The final large production run C-46D arrived in 1944–45, and featured single doors to facilitate paratroop drops; production totaled 1,430 aircraft. Although a one-off XC-46B experimented with a stepped windscreen and uprated powerplants, a small run of 17 C-46Es had many of the same features as the XC-46B along with three-bladed Hamilton-Standard propellers replacing the standard Curtiss-Electric four-bladed units. A last contract for 234 C-46Fs reverted to the earlier cockpit shape but introduced square wingtips. A sole C-46G had the stepped windscreen and square wingtips but the end of the war resulted in the cancellation of any additional orders for the type.

" (as the Himalaya Mountains were nicknamed by Allied airmen), transporting desperately needed supplies to troops in China from bases in India and Burma. A variety of transports had been employed in the campaign, but only the C-46 was able to handle the wide range of adverse conditions encountered by the USAAF. Unpredictably violent weather, heavy cargo loads, high mountain terrain, and poorly-equipped and frequently flooded airfields proved a considerable challenge to the transport aircraft then in service, along with a host of engineering and maintenance nightmares due to a shortage of trained air and ground personnel. After a series of mechanical gremlins were resolved, the C-46 proved its worth in the airlift operation. It could carry more cargo higher than other Allied twin-engine transport aircraft in the theater, including light artillery, fuel, ammunition, parts of aircraft and, on occasion, livestock. Its powerful engines enabled it to climb satisfactorily with heavy loads, staying aloft on one engine if not overloaded, though "war emergency" load limits of up to 40,000 lbs often erased any safety margins. Nevertheless, after the troublesome Curtiss-Electric electrically-controlled pitch mechanism on the propellers had been removed, the C-46 continued to be employed in the CBI and over wide areas of southern China throughout the war years.

The C-46's huge cargo capacity (twice that of the C-47), large cargo doors, powerful engines and long range also made it ideal for the vast distances of the Pacific island campaign. In particular, the U.S. Marines found the aircraft (known as the R5C) useful in their amphibious Pacific operations, flying supplies in and wounded soldiers out of numerous and hastily-built island landing strips.

Europe

Although not built in the same quantities as its more famous wartime compatriot, the C-47 Skytrain, the C-46 nevertheless played a significant role in wartime operations, although the aircraft was not deployed in numbers to the European theater until March 1945. It augmented USAAF Troop Carrier Command in time to drop paratroopers in an offensive to cross the Rhine River in Germany (Operation Varsity

 famously issued an edict forbidding the aircraft's use in future airborne operations. Even though the war ended soon afterward and no further airborne missions were flown, the C-46 may well have been unfairly demonized. The operation's paratroop drop phase was flown in daylight at slow speeds at very low altitudes, by an unarmed cargo aircraft without self-sealing fuel tanks, over heavy concentrations of German 20 mm, 37 mm, and larger calibre antiaircraft (AA) cannon utilizing explosive, incendiary, and armor-piercing incendiary ammunition. By that stage of the war, German AA crews had trained to a high state of readiness; many batteries had considerable combat experience in firing on and destroying high speed, well-armed fighter and fighter-bomber aircraft while under fire themselves. Finally, while many if not all of the C-47s used in Operation Varsity had been retrofitted with self-sealing fuel tanks, the C-46s received no such modification. Although 19 of 72 C-46 aircraft were shot down during Operation Varsity, it is not as well known that losses of other aircraft types from AA fire during the same operation were equally as intense, including 13 gliders shot down, 14 crashed, and 126 badly damaged; 15 B-24 bombers shot down, and 104 badly damaged; 12 C-47s shot down, with 140 damaged.

During the war years, the C-46 was noted for an abnormal number of unexplained in-air explosions (31 between May 1943 and May 1945) that were initially attributed to various causes. In particular, the fuel system, which was quickly designed, then modified for the new, thirstier Pratt & Whitney engines, was criticized. The cause of the explosions was eventually traced to pooled gasoline from small leaks in the tanks and fuel system, combined with a spark, usually originating from open-contact electrical components. Though many service aircraft suffered small fuel leaks in use, the C-46's wings were unvented; if a leak occurred, the gasoline had nowhere to drain, but rather pooled at the wing root. Any spark or fire could set off an explosion. After the war, all C-46 aircraft received a wing vent modification to vent pooled gasoline, and an explosion-proof fuel booster pump was installed with shielded electrical selector switches in lieu of the open-contact type used originally.

Postwar

Overall, the C-46 had been successful in its primary role as a wartime cargo transport, and had benefited from a series of improvements. Like the C-47/DC-3, the C-46 seemed destined for a useful career as a postwar civilian passenger airliner, and was considered for that purpose by Eastern Airlines. However, the high operating costs of the C-46 (up to 50% greater than the C-47), soon caused most operators to change their minds. Consequently, most postwar C-46 operations were limited to commercial cargo transport, and then only for certain routes. One of the C-46's major drawbacks was the prodigious fuel consumption of its powerful 2,000 hp engines, which used gasoline at a much higher rate than the C-47/DC-3. Maintenance was also more intensive and costlier. Despite these disadvantages, surplus C-46s were used by some air carriers, including Capitol, Flying Tigers

 to both carry cargo and passengers. Many other small carriers also eventually operated the type on both scheduled and non-scheduled routes. The C-46 became a common sight in South America, and was widely used in Bolivia, Peru, Brazil, Argentina and Chile, especially in mountainous areas (where a good climb rate and high service ceiling were required) or to overfly deep jungle terrain where ground transport was impracticable.

C-46 Commandos also went back to war, serving in both Korea and Vietnam for various USAF operations, including resupply missions, paratroop drops, and clandestine agent transportation. The C-46 was not officially retired from service with the U.S. Air Force until 1968. The type also served under a U.S. civilian agency, the Central Intelligence Agency

The C-46 played a supporting role in many clandestine operations during the late 1940s and early 1950s, including resupply efforts to Chiang Kai-Shek's troops battling Mao's Communists in China as well as flying cargoes of military and medical supplies to French forces via Gialam Airfield in Hanoi and other bases in French Indochina.
