The Lockheed Model 188 Electra is an American turboprop airliner built by Lockheed. First flying in 1957 it was the first large turboprop airliner produced in the United States. Initial sales were good but after two fatal crashes which prompted an expensive modification program to fix a design defect no further orders were placed. The type was soon replaced by turbojet airliners but many were modified as freighters and the type continues to operate in various roles into the 21st Century.
Made by Lockheed Corporation.
Lockheed L-188 Electra is the predecessor of the Lockheed P-3 Orion.
