The Navy had plans to do away with all electronic navigational systems.
Basically all of them. All with Chinese crap in them.
For me the whole “Navy had plans to do away with all electronic navigational systems” points to the terrible state of training in our fleet.
“when I was in and the ships were wood and the men were steel” da da da da dah....we had to demonstrate through a week of refresher training that we could fight the ship without any of the electronics. So we would be doing an activity and they would say... your satnav just went down (switching to xxx)... your xxx just went down.... switching to visual triangulation and/or celestial navigation. Had to show it for almost all our systems: navigation, tracking and weapons control, engineering, auxiliary systems, damage control....even made the Disbursing Officer and Classified materials guys go through their evacuation and destruction protocols.
The culmination of the week was “killing off” all the senior officers and NCOs to see how the crew handled things for about 15-20 minutes prior to the abandoning ship drill.
