Aren't there major American naval assets in Okinawa? Why weren't they detected by our antisub devices? Why did the japs pick up on this threat first? Or did we just toss them the ball for the followup? IOW, we detect the bogey and give it over to indigenous forces to check out? I'm foggy on my geography. How strategic is Okinawa? What would be the future use for data collected from such a recon?
Wasnt there a threat to the USS Kitty Hawk a while back? Kitty Hawk is based in Okinawa.
