Yeah old school navigation was map, compass, speed indication and a stopwatch.
GPS is really nice but not a guarantee in a war so you take that same process but with all the modern instruments (laser ring gyros are worth a google), onboard digital map data and it can be pretty self sufficient





















It sucks but I kinda get it. You can’t get radars yet and the more the planes sit around a production line the longer it takes for the units to do acceptance inspections, train technicians and get pilots seat time. A plane without a radar is still a plane, and maybe with all the data sharing abilities it can be worked around. Absolutely not combat capable though
It’s incredible how it came to this. And this is peacetime production and logistics!
