The DC-2 was a twin-engined, all-metal, low-wing monoplane with retractable landing gear. The crew of two, pilot and copilot, sat side-by-side in the cockpit. The main landing gear retracted into the nacelles but about one-third of the tire was left exposed as a precaution in the event of a wheels up landing; the tail wheel was full swivelling but did not retract. The wing extended beneath the fuselage and served as a mounting for both engine nacelles. The entire aircraft, except for the control surfaces, was made of high-tension strength aluminum alloy known as Alclad; the control surfaces, i.e., ailerons, rudder and elevators, were metal framed covered with fabric. Since these were transports, the aircraft had a standard passenger door on the port (left) side of the fuselage aft of the wing. All of the DC-2's were built at the Douglas plant in Santa Monica, California.
The Navy ordered five DC-2's in two different series. All five aircraft were designated R2D-1's. The first three aircraft were DC-2-125's that were delivered in November and December 1934; two aircraft went to the USN and one to the U.S. Marine Corps (USMC). The fourth and fifth aircraft were DC-2-142's that were delivered in September 1935, one to the USN and one to the USMC. The two suffixes, -125 and -142, indicated the interior fittings and other variations between groups of DC-2's. All five aircraft were powered by two 750 hp (559.3 kW) Wright R-1820-12 nine-cylinder, single-row, air-cooled, radial engines driving Hamilton Standard variable pitch three-bladed propellers.
The USAAC also purchased 58 DC-2's and designated them XC-32, C-33, C-34, C-39, C-41 and C-42. During World War II, another 24 DC-2's were impressed by the U.S. Army Air Forces (USAAF) which superseded the USAAC on 20 June 1941.

Douglas B-18 Bolo
Developed from the DC-2 civil transport, the Douglas DB-1 was designed in 1934 as a replacement for the USAAC's standard bomber, the B-10. The DB-1 was the losing contender in the USAAC contest, which was won by the Boeing B-17. Despite this, the DB-1 entered production as the B-18, with most of the USAAC's bomber squadrons being equipped by B-18s or B-18A's in 1940. The majority of the 33 B-18A's stationed with the USAAC in Hawaii in 1941 were destroyed in the Japanese attack on Pearl Harbor. When the B-1 8 was replaced in first-line service by the B-17 in 1942, some 122 B-18s were equipped magnetic anomaly detection (MAD) equipment for deployment in the Caribbean on anti-submarine patrol. Some B-18s were used for transport duty, with a portion of these designated C-58s.
