The Lockheed 18 Lodestar was a passenger transport aircraft of the Second World War era. The prototype, which first flew in 1939, was constructed from one of a batch of Lockheed L-14 Super Electras which had been returned to the manufacturer by Northwest Airlines after a series of crashes of L-14s. The fuselage was lengthened by 5 feet (1.5 m), enabling the fitting of two more rows of seats and hopefully making the aircraft more economical to operate. However, most US airlines were by then committed to purchasing the Douglas DC-3, and Lockheed found the Lodestar difficult to sell at home.
Overseas sales were a little better, with 29 bought by the government of the Netherlands East Indies. South African Airways (21), Trans-Canada Air Lines (12) and BOAC (9) were the biggest airline customers. Various Pratt & Whitney and Wright Cyclone powerplants were installed.
When the United States started to build up its military air strength in 1940-41, American operated and part-built Lodestars were impressed for Army or Navy services under various designations. Lend lease aircraft were used by the RNZAF as transports. Post war, many of the New Zealand aircraft were later used for aerial topdressing.

- R5O-3 (2) 1,200 hp (895 kW) Pratt & Whitney R-1830-34A. Originally 4-seater VIP transports.
- R5O-4 (12) 1,200 hp (895 kW) Wright R-1820-40. Impressed. 7-seater staff transports.
- R5O-5 (14) 1,200 hp (895 kW) Wright R-1820-40. Similar to the R5O-4 but had 14-seats.
