Linden Assembly was a General Motors automobile factory in Linden, New Jersey. The 2,600,000-square-foot (240,000 m2) factory opened in 1937 to build Buick, Pontiac, Cadillac, and Oldsmobile vehicles from "knock down kits". During World War II, the plant was also used to produce fighter planes for the United States military, primarily the FM Wildcat, an improved version of the F4F Wildcat, as it is ajacent to the Linden Airport. After automobile production resumed, it was under the management of GM's newly created Buick-Oldsmobile-Pontiac Assembly Division created in 1945.
