North American Aviation replaced by North American Rockwell
Merger and acquisition
The fatal Apollo 1 fire in January 1967 was partly blamed on the company. In September, it merged with Rockwell-Standard, and the merged company became known as North American Rockwell. During this period the company continued its involvement with the Apollo  program, building the Command and Service modules for all eleven missions. Within two years the new company also was studying concepts for the Space Shuttle, and won the orbiter contract in 1972. In 1973, the company changed its name again to Rockwell International and named its aircraft division North American Aircraft Operations.
