The Lockheed Model 12 Electra Junior is a low-wing aircraft made by the US American manufacturer Lockheed . The twin-engine low-wing aircraft was equipped with a double tail unit and a rear wheel landing gear. A maximum of six passengers could be transported. The crew consisted of two pilots. The Electra Junior is a scaled-down version of the Lockheed Model 10 Electra with a shortened fuselage. The first flight took place on June 27, 1936 .
The NACA used at times a machine for studies on wing deicing . A total of 130 machines of this type were produced.
The military version of the USAAC and USAAF , designated the C-40 and UC-40, respectively, served as a transporter, liaison aircraft and for training purposes. One of the seven machines delivered to the US Navy , called the JO , was the first twin-engine aircraft ever to land on an aircraft carrier (on the Lexington in 1939 ). For this purpose, this machine (Bu.No. 1267) was equipped with a nose wheel landing gear .
In 1939 the Netherlands ordered 12 machines for use in the Netherlands Antilles . The aircraft designated as model 212 had a turret on the top of the fuselage and in addition 400 kg of drop armament could be carried at outstations. The unit price was $ 690,000. The machines delivered in 1940 remained in use until the Japanese invaded in 1942.
