A oft-repeated story I heard from older VP and VQ hands the crewmember who often found a sub was the FE, who was just looking out the windows.
An oft-repeated statistic when beginning "Intro to ASW." It's certainly a plus to have eyes out, but that part is actually benefited by current technology surprisingly well. Of course, sensor AND eyeballs would be my personal choice.
But for my specific scenario mentioned...
Could they put cameras in all directions like these new luxury SUVs have, where you can look left, right, front, rear, etc...?
I would argue no. Not for what you'd be looking for AND having the precision to put the aircraft right where it needs to be build a reliable solution, especially with our current weapons.
