Design Flaw?

By Phil Gardocki
My Navy role was as a ship-to-air missile man. I did not really keep up with the advancements in anti submarine warfare. What I knew was interpreted from World War Two events and Hollywood movies of dealing with subs with limited endurance, usually less than 24 hours, being brought to the surface after a dramatic cat and mouse game.

You can imagine the great excitement when it was announced that our squadron of three destroyers had run across a Soviet submarine, believed to be a Foxtrot. We were going to see if we could bring it to the surface. I was only an observer in this evolution, and watched the slow dance of three ships moving counter-clock wise in a slow circle, each ship taking turns actively pinging the waters and tracking the sub in the depths. As the hours went by, our anticipation grew, to be the first to spot boiling waters that would herald the arrival of the ascending ship.

Then, as the days went by, our agitation grew, as sleepless night were spent listening to the high energy squeal of the sonars. On the third day, one of our ships had to break formation, as it was running low on fuel. We knew that we were also only 24 hours from that breakpoint ourselves.

I finally asked myself the question, "How long can it stay down there?" I realized I had the answer and went to my book,  All the World’s Navies.

The answer is 28 days.
Yes, a diesel powered Soviet Sub can stay underwater longer than a United States destroyer can stay above it.
