Then every admiral from Richardson on down needs to be fired because they all learned basic seamanship without all this stuff and know that these may be great aids, but are not a substitute for seamanship. Adm Richardson qualified subs in about 1985 back when surface navigation on a sub was still very much Mk 1 eyeball, with some long range lookout done by an enlisted eyeball in the control room on an optical periscope - a great instrument to be sure, but you dodged surface traffic including small boats by seat of the pants driving.
