    My "no" related to what I thought you were saying that inertial was only for use in the missile.

    Gary,
    Sorry, I don't understand the meaning of your "No" :-)
    Inertial system was also developed for submarine.
    But what I was discussing was the MISSLE GUIDANCE SYSTEM.
    Which according to Wikipedia was inertial.

    The submarine could use any navigation system, and I suppose
    inertial one was less accurate than Cel Nav.
    And that Transit was developed with the explicit purpose
    (or one of the purposes) to improve the missle submarine navigation.
    Again, I learn this from the Wikipedia article).
    So apparently inertial nav for a submarine, was not sufficient.

    Alex.
