Yes,Most the Navy has a very electronic bridge,and uses it most the
time, but, the magnetic compass on board is called " the standard
compass" every half hour and every change of course regulations
require a compass check between the gyro and the magnetic. On the
Intrepid, I do remenber loosing gyro and steering the standard. The
idea may be if you are in far deep water, do you want a electronic man
or a navigator with you to take over in Emergency.
