If the Navy is well-and-truly concerned about cyber warfare taking out their computing capabilities, then they would want to ensure that the computers they have STELLA on are "air gapped" from the rest of the ship's network. But unless the STELLA computer lacks USB ports, you can't depend on that workstation being totally isolated, air gaps or no. If their STELLA computers are NOT air gapped, then they would want to be teaching people to use Pub. 249 or their hand-held calculators.
Taking it a step further, if they are concerned about EMP from a nearby nuclear blast frying the chips on computers and calculators alike, then they would want to be teaching people to use Pub. 249.
Being children of the 21st century, they may well be using electronics in one way or another to do 100% of their sight reduction. If so, it would seem to be slightly counter productive to teach an "emergency navigation method" that you may be unable to use in an actual emergency.
