Depth Control Problem

Sub Sailor · 12-26-05, 10:11 AM

I have mentioned this condition is an earlier post, and I have fisnished running a series of tests. The tests are only on the 688i, Seawolf, and Akula.
What I have noted is when you are takeing evasive action and answer a flank bell you boat goes deeper. In fact it is a significat drop and makes it impossible to operate in shallow water and take evasive action if that becomes necessay. I am going to report the average of 10 test per boat. Each boat is at 600 feet(200 meters for the Akula), each boat is answering a flank bell and I inputed the course to insure that it was always the same. I tried using the compass rose but could not get consistence in my course change. All course changes are 180 degrees.
Also because I was in very deep water I allowed each boat to regain odered depth and each did so. I did encounterd a problem with the Akula I have no explanation for, and that was, it would report steady on course but the turn always continued. I would have to stop it from the orederd course meter.

688i Finished the turn 279.4 feet below odered depth.

Seawolf Finshed the turn 208.8 feet below odered depth.

Akula Finished the turn 94 meters(308 feet) below ordered depth.

So if you are in a shallow water operations and a Helo gets on you and drops you are in a heap a trouble. You are probably going to crash.

Also before anyone ask-I tried to control depth by odering a shallower depth on the turn- never could accomplish it, the boats kept dropping until the turn was finished and then each would recover depth. I was never able to effect the drop.

I don't know how to fix it or if it can be fixed, but I never experienced this in SC or in earlier versions of DW.

All I can say in real life submarines maintain depth control in the turn. Oh and I tried some at max depth just for fun, the boat goes below crush depth and they do crush in DW, also in every case starting at 600 feet, each boat would go deep enough to cause significant hull popping.
