Good lord.

I have "chased" a number of submarines when I was in the Navy.

The ARA San Juan (S-42) is a diesel-electric sub that, if the CO can take a healthy dump, would never be found by a single helo or ship. Never.

I did a number of "Pass-exes" with the Australian diesel-electric subs. They were ass kicking machines and we had a bunch of assets arrayed against them.

As a comparison, Russian nukes made more noise than Dipso, as easy to track as a neighborhood bully. Diesel-electric subs are like Rikao, quiet and unassuming until they get tired of being that.

Also, the only time we ever tracked US subs was during exercises when they had to help us find them.

The CO of the San Juan made a mistake without connection to some British helo or ship practicing Helen Keller ASW.
