Semantics.

Not really. On the Trident Missile General Electric makes guidance units. Lockheed makes flight controls.

Anyway, a modern smartphone can achieve both tasks because it has all
the sensors required. Please let me repeat my post:

It is very easy to make a rocket. The difficult part is the flight
control unit that keeps the rocket flying straight and narrow instead of
going in random directions after liftoff and crashing back to earth near
the launchpad.

A modern smartphone has all the sensors required to let the rocket
correct its course and guide itself to its destination.

All you need to do is write an App and send the output to an interface
to control the power of each of the three nozzles (a rocket has no wings
or rudder, so a minimum of three nozzles would be needed to make the
rocket go in any direction you want it to).
