Need some advice with underwater evasion...

Sardaukar67 · 04-15-07, 06:41 AM

I' playing NYGM and find enemy ASW ships very challenging...I'd say daunting. So far I haven't been able to evade escort groups but once when they ping me...and this is only 1939-early 1940, captaining shiny VIIIB U-Boat.

Radical course changes with high speed, then going silent with 1 knot etc. do not work. After a minute I get "Enemy is pinging us!"

Getting sub pointed away/towards escorts to reduce profile does not seem to work either...they seem to have unreal ability to detect the sub, be the profile/distance be whatever. Managed to survive 20 hrs underwater against DD, Black Swan frigate and couple of Flower corvettes in shallow (110 m water depth) but no matter what I did I could not shake them off.

Same happened when couple of V&W destroyers who spotted me when cruising towards home...even when going down to 150 m and doing every maneuver I could think of, they DC'd me out of existence.

Any ideas/help ? How do you survive situations like that ? Or is it "game reload time" every time I get spotted by multiple ASW ships ?

go silent, go deep
and by deep i mean +220 meters
i normally go down to the edge of 250 meters when im being attacked by surface ships

Is my VII B going to survive 220 m ? I mean that'd be easy victory for enemy if I reach crush-depth !! :p

At least early in the war you can avoid their ASDIC's by going silent below ~200m. And not go into shallow waters might be of help with that.

I'm currently in late 1941 with a IXC and usually I can escape by doing as above, and by trying not to give them my broadside to maintain a smaller pinging target. Later in the war it might get harder though.

Well..if I get orders to patrol AM 97 or such there is not much I can do about it..it's all shallow (100 +m). Maybe I should just use SHPatrol...:p

But I guess going below 200 m is way to go.

You should be OK down to 220m as long as your boat is not damaged. I can;t remember what NYGM's crush depth settings were but I recall it was fairly deep even for VIIB's.

The quiet deep advice is as good as it gets. I don't even bother to change course much any more, but when I do I only use 10-15 degree rudder to keep my speed up.

This is what works for me:
Speed, 1 knot, silent running, beginning depth 100 meters, maximum rudder deflection 10 degrees.

If they drop DCs on top of me -- flank speed until reaching 6 knots, back to one knot. The added speed will quickly change my position and depth.

Read further details on my webbie.

Good luck
