Super-duper escorts

[HMCS]

I was stalking a task force for a shot at a BB for the first time ever, which made this all the more ANNOYING...

A Hunt II came barrelling at me, pinging away with ASDIC at 18 kts.

Pardon-moi. I thought that that was too fast for either passive or active sensors.

I've had a very similar problem, and quite a number of times. That's when I usually send an acoustic torpedo the escort's way. A few short seconds later my problem with the escort is over.

He was trying to make you crap your pants and do something which would be very helpful to him.

HMCS I'm guessing that he first got a hydrophone fix on you and then raced like heck to your "last plotted" location to reaquire you with shorter ranged ASDIC.

(We can't make them stop pinging on the way to the "last plotted U-boat position" though.... SH3 quirk.)

The high speed of the escort in question is certainly a great hindrance in his effort to detect you due to white noise.

In general though, ASDIC is less affected by upper level water noise than hydrophones.

In real life, ASW detection devices would be retracted back into the escort's hull at speeds of 15 kts or better. (Generally speaking) The risk was having said devices torn free by hydrodynamic forces impressed upon them above speeds of 15kts.

Technically, they could still listen to hydrophones/sonar at high speed in RL... but the usefulness of doing so... and successful plotting, is another matter.

Still, when you play DiD... any time you see that DD make a beeline for you through the scopes... with that bone in his teeth... it is suspenseful every time.

This cat picked me up at 18 kts, on his beam. I was at periscope depth, speed 4 kts. He was 2000 yds away or so. And no, my scope was down. I'm very good with the 'scope, I don't leave it up for long @ all.

I have a hard time with that one.

I guess "realism" is relative. C'est la guerre.

At 4kts, and 2000m you can definately be heard by hydrophones given the right conditions.

You aren't simply automatically detected.

What was your aspect ratio in reference to the searching unit?

Did you fire T1 steamers?

Were you running silent? (4 kts implies that you were not.)

What was the sea state.

There are too many unanswered questions here for you to state that the sensors are modelled by us arbitrarily or for you to imply that we just modelled these things haphazardly with disregard to realism.

Suspensful my unshaven sternquarters. Terrifying is what it is. A Tribal coming at me full flank and hammering the active trash. Gives me grey hairs thinking about it.

I love the GWX escorts!

they make me consider what will happen to good ship and crew if my approach to the convoy fails.

then they make me consider what will happen to good ship and crew if im too careless in gathering target data.

then they make me wonder what will happen to good ship and crew if i maneuver to wrecklessly while lining up for the shot.

once the shot works out they make me wonder if im egressing smartly (getting the F outta dodge without making a lot of noise)

more often than not im detected at some later phase of the engagement and these buggers force me down to 230 - 240 meters as we play a deadly game of hide and seek... fortunately over several years of playing sub sims... i have learned how to turn my U-boat into a church mouse hiding quietly in the darkest corner of hell.

that lesson did not come easy over the years.

GWX - first the test... then the lesson!

Variables, shmariables.

A DDE going at full tilt (18kts) would be lucky to hear anything. Remember, we are talking about 60 years ago. The technology is not what it is now. Next time I am at the Legion on Remem. day, I will have to try to track down an old asdic operator and see what he says. I know that the U-Boat cats were certainly contacted and interviewed about development of the game, but I don't think that they talked to too many escort crewmen.

I'm done with this, just going to live with it.

It's just a GAME for pete's sake.

haha i had the problem in Med lol, came across a British Battlegroup of 3 battleships (King George V, Rodney and Nelson) 2 cruisers, and some destroyers. Peeeerrrfeccct weather :D , so i make my move ...all ahead slow - rig for silent running. Then PING........PING...... PING....PING..PING i quickly turn my pere- round and there was one of those damn Hunt II destroyer's speeding towards me pull pelt!..i was going too slow to make any considerable depth and she runs across me, hitting my flak guns with her hull, only damaging them, then to my luck the depth charges where set too shallow so didn’t cause much damage, and to make things even better, they blew off the depth charge rack ! HAHA she didn’t pester me for much longer !.

Considering i was ahead of the group, i sat and waited for the BB column to come by King George V first..Fired Torpedo 1 (450 metres)...direct hit on the engine room, she slows to a complete stop, the other ships start manuver N.W, so i move ahead flank turning in the same direction… but 2nd BB in the line was speeding away and judging by my angle the torp would have bounced off , but i manage to get close to the 3rd BB (fire 3 shots frm 500m) 2 of which hit, grinding her to halt, thankfully the rest of the escorts follow the BB that got away, leaving me with 1 BB dead in the water and 1 managing only 6 knots, bow in the water.

I moved in and fired 2 more torps at the Rodney class BB thus sinking her, and then moved back to the King George, positioned myself perfectly, at 700 metres, then PING PING again, i thought i lost all the Destroyers, just as well there was only this 1 straggler, i knew that from her distance from me i could quickly fire my last torpedo at the BB,so i fire it at 700 metres, and watch from my periscope, then to my horror, i see it come directly between me and the BB, in the line of fire of my torp MY LAST TROP !..boom..the Destroyer was no more.. i was most annoyed ! because it was looking that the BB wouldn’t sink and was still pretty much manned at all guns..putting me off from surfacing.

I slowly slip away somewhat disappointed...then at my complete surprise 10 minutes later, the navigator has identified the BB as sunk, the icon appearing on the map !,

2 BBs sunk, and 1 DD,.. and i lived to tell the tale!
- Jesus that has to be the luckiest patrols ive done, although it could have gone all the other way had the Destroyers and their Escorts had their way..one very fortunate skipper indeed ! :)

They are driving you, like they try to do to Ramius.:lol:

Yeah, looking at his post history... he's already made the statement that he likes to stir the pot. He's just stuffing popcorn in his face.

Just another griefer.

@HMCS, here's a thought... GWX didn't cost you anything. Why don't you just take it off your hard drive and be done with it. You were given constructive responses. I don't have time for people who ignore them.

I'm inclined to believe that you simply weren't as stealthy as you thought you were.

[Mooncatt]

well any attacks i carry out (or try to) on conyoys, task forces or a flock of seagulls, i never travel above 2 knts and always silent running from below 7000 range. above that range i can travel a little faster 4-5knts, but you just have to be as silent as possible. imo 4 knts at 2000 range is too noisy, silent running automatically reduces your speed to what is assumed is relatively silent (3 knts) i drop down to 2 knts to be sure.
if you use this technic you might find you can get very close without being detected (ive got as close as 1000 and still not been picked up) you just have to hope that your intercept calculations have been precise, if not then its start all over again time.:damn:

Yeah youre right ahead slow doesnt cut it... gotta be two knots or less.

A submurged U-boat travelling at 3 to 5 knots regardless of silent running is a lot easier to hear than one might think... even with ww2 technology.

books, articles and web pages i have read indicated that destroyers would use ASDIC while rushing toward the contact at 15 - 20 knots in order to close the distance quickly, while still maintaining a slow enough speed for their equipment to be effective in plotting the position of the u-boat. - above 20 knots their listening and pinging equipment is pretty much useless

A couple of N Class DDs have kept me running for my life for the past 3 1/2 hours!

Battery level just above 50%

Air is OK

Depth is 252 meters

No torps left

they circle over and over hounding me. for the past hour, they have just been dropping about 3-6 DCs on me....down from their 10-12 patters for the first two hours. So far been rattled a couple of times...but no damage. At 250 meters or so, I should be too deep or under a thermal layer so they cannot track me. :x

I've been shaking my fist at the bastards for a while now....they have to run out of DCs eventaully??? maybe??


I just transferred 4 of my 5 officer to their own boats....looks like they may be the only survivors of U-178.

We had beans and cabbage for lunch, is Bernard's farting giving away our position?? how do they do it?

Dont worry... they will get slaughtered on their first patrol.

Edit: Yes... depeding on your realism settings they will run out of DCs sooner or later

[Mooncatt]

i have done he same as you before i learnt this. all you have to do is this.....
if there is 2 on your ass .....stay at you current depth and change course by 5 degrees every 5 mins.......say........180.....185....190.....195.. ...back to 190.....185 you get the picture, just dont head in circles.
if one dd is on you then you have more options..........
stay at depth your at, after he makes a pass at you and drops charges go ahead flank for 7 secs and change course by 45 then back to 2 knts. keep doing this until he buggers off. believe me these two tacs have been a god send to me and they do work for me.
