The Apollo 11 spaceship was a complex system made by several companies, but the primary contractor was North American Aviation. They built the Command and Service Modules (CSM), which carried the astronauts to and from the Moon.

Here are some other companies involved in the development of the Apollo 11 spaceship:

* Grumman: Built the Lunar Module (LM), which landed on the Moon.

* Rocketdyne: Designed and built the F-1 engines for the Saturn V rocket, which launched the Apollo 11 mission.

* Boeing: Supplied the Saturn I and Saturn IB rockets used for early Apollo missions.

* General Dynamics: Built the S-II and S-IVB stages of the Saturn V rocket.

* IBM: Developed the Apollo Guidance Computer used for navigation and control.

It was a massive undertaking, requiring the collaboration of thousands of engineers, technicians, and scientists across multiple companies and government agencies.
