The development and subsequent production of Lockheed Electra aircraft were conducted in order to create competitive capacity aircraft that could compete in their flight-technical qualities of the airplane with another US aircraft manufacturers - Boeing 247. Given the fact that the creation of Lockheed Electra was conducted from the ground, a number of parameters of the aircraft still managed to bypass the model Boeing 247, however, a large production run and because the airliner was not.

Unlike previous aircraft models produced by Lockheed Aircraft Corporation, the Lockheed Electra aircraft was made entirely of metal, which increased the load-bearing capacity of the fuselage structure and made it more reliable in operating conditions. Nevertheless, this factor led to the fact that the cost of the aircraft, in comparison with preliminary calculations, has seriously increased, which, according to experts, led to the refusal to continue the production of such aircraft.

To improve the aerodynamics of the aircraft, as well as to improve the agility and controllability of the aircraft tail section was bifurcated, which is one of the very characteristic differences of this model.

The power plant of the aircraft is represented by two Pratt & Whitney R-985 Wasp Junior SB piston engines, capable of developing 450 hp. each, and fly at speeds of about 325 km / h (maximum flight speed).

On board the Lockheed Electra aircraft can accommodate up to ten passengers, with, if necessary, the salon can be quite quickly converted into a cargo bay, which allows the aircraft to operate as a transport aircraft.

In 1937 year, aeronautical engineer from Lockheed Aircraft Corporation presented a model Lockheed Electra 10-A, available in several different versions, including for military purposes, for civilian passenger and cargo traffic. The distinguishing feature of this version were only minor improvements, in particular, reinforced fuselage, a new arrangement of the passenger compartment, the new seat, etc. The current modification of the aircraft has become popular of all lineup - 101 plane was built in a short production cycle.

Modification Lockheed Electra 10-B was introduced in 1939 year, and its main distinguishing feature is the new engines Wright R-975-E3 Whirlwind, able to develop a total capacity of 880 hp, and an updated control panel. The model was produced for civilian purposes, maybe, for the Air Force United States.

The Lockheed Electra 10-C version was introduced in 1941, and eight aircraft were built specifically for Pan American Airways. The aircraft was equipped with easy-to-maintain and highly reliable Pratt & Whitney R-1340 Wasp SC1 engines, each of which provided 450 hp.

In 1942 year, the American aircraft manufacturers specifically for the US Air Force, developed a model of Lockheed Electra 10-D, which is a transport aircraft, calculated as the carriage of goods and for the transportation of troops. However, the model has not been put into production.

The Lockheed Electra 10-E was introduced in 1937 and was powered by improved Pratt & Whitney R-1340 Wasp S3H1 propeller engines, each with 600 hp. The model was produced in conjunction with the Electra 10-A version, and it was this modification that was used by Amelia Earhart to fly the first woman around the world.

Lockheed XC-35 is an experimental version created on the basis of the base model, with a pressurized cabin and turbocharged engines Pratt & Whitney XR-1340-43, with a total power of 1100 hp.

Model Lockheed KXL1 - a special version of the identity of the aircraft, designed for the Japanese Navy,

At the moment, airplanes Lockheed Electra still continue to operate, but in a very limited number - according to official figures, at the end of the year 2014, in the whole world has been used only 5 aircraft of this model.
