We’d go total emcon and no nav lights then ahead flank until they got up to speed. Then we’d go back full until they figured out the closure rate was 45kts, then back to ahead flank. After a few iterations of that they’d normally be DIW belching smoke and we’d turn back on the lights and radars and steam away.
No turns? Just ahead flank then back then ahead. Straight forward and straight back. That’s amazing. Destroyers are what us sub sailors try to avoid. Some times it works great then other times it don’t. I was told if the carriers want to leave any of us “they’re gone”. When we were hunting it was always quiet.
