North American Aviation's president had inspected the field by December 1940 when the US government approved construction of a Kansas City production plant to produce B-25 Mitchell bombers for the USAAF and PBJ-1D bombers for the US Navy.

Contract W535 AC 19341 for the initial production of 1,200 B-25D (NA-87) bombers was approved on June 28, 1941; production began in December 1941.
