View Full Version : Decks awash

New career, 2nd patrol. First patrol was largely a bust (a couple of small merchants) - weather turned lousy so I aborted and returned to base early.

Next mission was to BF somewhere (11 I think). For 1939 this is a long way. What about a short cut? I'll go past Scapa and save a lot of fuel! Naturally, it occurred to me that if I was going past I might as well drop in for a visit. Departure from Wilhelmshaven 9 Oct. I timed things so that I reached the outer approaches to Scapa at dusk on the 12th. Soundings indicated that there was only 12 meters depth below keel. Just about any dive will bottom out. Only at this point did I recall people talking about how shallow it was. I didn't realize it started so far out. Weather conditions were good: 6 m/s windspeed, light fog.

I set course for the interior of Scapa, ahead slow. I was running at x32. Ship spotted! A J-type DD was approaching, distance was around 4500 meters, bearing 30, medium speed. I watched it approach. At around 2000 meters I decided to dive and went all stop. The DD circled me and medium range and proceeded off bearing around 320 degrees. I checked depth under keel. Two meters! This would never do. The next time I tried this I might sink my bow in the mud.

Then I thought, I wonder if it's possible to run with decks awash? I began to fiddle with the depth settings. I found that at depth 7 meters the diesels still run but the watch crew goes below. So, up scope, ahead slow.

I started getting hydrophone readings - not bad. There were 2 or 3 warships in the inner harbor meandering around. I continued on.

Shore searchlights spotted! (Don't remember hearing about those in the accounts. Will they fix on me and call in the escorts?) I continue on and nothing happens. (I had heard people talk about anti-submarine nets. As I began my passage of the final channel about every minute or so I made a tick mark of my position so that I could find my way back. In the event, I seem to have avoided the nets.)

As I enter the inner harbor, the hydrophone readings on "warships" resolve into 2 DD's at around 4000 meters. One DD is stopped, the other is patrolling. I start feeding targeting data to the TDC on the patrolling DD. At 2000 meters I see that the anchored DD is going to be a problem. I'm afraid to leave the main channel because of what I've heard about the anti-sub nets. My course will take me within 1000 meters of the DD. At the same time, the other DD has made a leisurely turn and is headed in my direction. Clearly I haven't been spotted but things are starting to get dicey. The SO tells me that a third DD is moving away, bearing around 270, long range.

At this point I'm at all stop. The approaching DD is now at 1500 meters. It will pass within 500 or so if it doesn't alter course. Once I start firing torps all hell will clearly break loose.

There's nothing for it, I decided. At around 1000 meters I fired at the approaching DD (a V&W?, I can't remember). I also targeted the anchored DD. I continued to feed target data on the approaching DD and gave orders to dive. Since I was at all stop this was agonizingly slow. The crew immediately began to reload. Before I was even at official periscope depth the approaching DD was enveloped in the explosion. A hit! About 1/2 minute later the anchored DD was hit.

At this point the SO indicated another warship was approaching - bearing around 30. This resolved into two more DDs of the same type. I went silent. The two DD's began to circle withing 500 meters of where the anchored DD was hit, their searchlights playing on the surface. One of them approached to within 1000 meters of my position but veered away. After about 15 minutes of this, THEY BOTH STOPPED AND ANCHORED!!

Unbelievable!!

Two tubes were still loaded. Ranges were 1500 and 1800 meters. LOS!

Two more explosions. Scratch two more DD's.

Back to depth 7 meters, creep ahead and reload. There was another DD out there somewhere.

Finally the Royal Oak appeared ahead. I wanted to position for a 90 degree shot. I crept to within around 1800 meters. Ready tubes 1 and 4, 0.5 meter spread, depth 0.5 meters under the keel. Fire! Ready tubes 2 and 3, same settings. Fire! Ahead 1/3 and reverse course. Set stern tube for default depth, impact - fire when tube comes to bear.

I was about halfway through my turn when the first spread hit - two explosions in short order. Searchlights pop on and the Royal Oak begins scanning in my direction. Two more explosions from the second spread. I fire the stern tube and prepare to dive if necessary.

My luck still holds. The stern torpedo hits and I get the ship destroyed message.

I set my course along the tick marks and crew reloads. Where is that other DD?!

Now I've reloaded and reached the outer channel. Still no other DD's. Are they searching around the grave of the Royal Oak?

I reach my last tick mark. I'm through! Surface, ahead standard. Bring in the external reloads.

About half way throught the reload process, "Schiff gesichte" (I play with the German language set.) Another DD. Or the J-type from before? I've made it to the edge of deeper water, so I dive and go silent. I spend the next 15 minutes (game time) or so as the DD proceeds on its patrol run. When its at long range and moving away I surface again, ahead 1/3 and start the reload process all over again.

Nearly done with reload - it's now around 0300 local time. Another ship spotted! Verdammt! A Flower Corvette. Ahead slow, and veer 45 degrees away. It turns in my direction. Am I spotted? Dive, silent running, then all stop. Passes within 1000 meters. Again I wait for the message that it is at long range and moving away. Surface, ahead 1/3, resume reload. After 10 minutes ahead full.

Again, I've just about reloaded when I get another ship spotted message. This is getting ridiculous. Again I try to skirt but have to dive. Again I surface and continue my run to the open sea.

Finally, I go to full speed for an hour and complete the reload. I encounted one more DD before I was clear but skirted it easily. By dawn I was in deep water and on my way to the patrol zone.

ADDENDUM: On the way to the patrol zone I encountered a convoy. I had only 5 torps left but I figued I might as well give it a shot. Naturally I waited until night to attack. There was only one escort, a Flower. I was able to avoid the escort and get into position. I then violated my own rule about targeting: there was a C3, T3, and T2 all lined up. Instead of firing a spread at the T3 and a single at the T2, I targeted each one, farthest first and then sequentially to the closest. First hit was a keel shot on the C3. It broke in half. Second hit about 1/2 minute later was the T3. It exploded immediately. Third hit was about only a few seconds later on the close T2. It too, exploded. By this point I was heading diagonally away and 1/3. Never saw the escore.

I think I ended up finding and sinking a lone tanker in my patrol zone before returning to base. Result was an amazing (for me) 80K tonnes. Equally amazing: no duds, 12 torps fired, all hits (but 4 of my targets were stationary).

Addendum to addendum: I'm a little hazy on what happened on the patrol after the convoy attack. I may have attacked two tankers that I had to finish off with the deck gun. I'm pretty sure about the 80K tonnage, however. I'll have to check the log.

How far away did you spot the Royal Oak? Im in Scapa now and I see nothing but shore line and harbor lights and I moved in as close as 2000m.
Im bummed out. No big ship to sink.

I frequently use the 7 meter wash. It's handly for getting a few hundred meters closer to the target before the dive, and giving me more surface time at dawn when the aircraft patrols are heavy and I'm forced to spnd most of the day submerged. Dive time is also greatly reduced.

It has the drawback of using quite a bit more fuel and speed is reduced as well as reduced visibility.
I use both scopes in this mode.

According to the Wiki-site for SH3, the Royal Oak is in Scapa from 4 Oct to 14 Oct 1939. I don't recall the link offhand but you can use a search engine to find the site, which also has information about other capital ships in port. I'm guessing that you missed the window on the Royal Oak. After patrol 1, I realized that I was within the window, hence my "detour".

Incidentally, I think I was extraordinarily lucky on this patrol. I tried Scapa early in playing the game didn't even make the channel before I had a DD on me. Now that I have more experience I desided to try it again. Also, the torpedoes didn't fail. The sea state helped in all my attacks: magnetic pistol is unreliable in heavy seas.

Perhaps this tactic has been discussed before but I'd never seen it. It seems to be very effective under certain circumstances. I wonder if I would have been successful in my Scapa mission if I hadn't tried it. Of course my luck with torpedoes and the strange behavior of DD's anchoring so that I could shoot them helped immeasurably.

Nice story, and well done. So there is a path into the flow without nets.

You were lucky to find it straight up first time!

Quite. I don't believe in "luck" but I sure seemed to have an inordinate amount on that patrol http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Strange, today I visited Scapa Flow for the first time. It was my 2nd patrol. So i went in, sunk 5 destroyers with my 5 torpedoes, still made it into the harbor, found nothing there, and came out. Didn't see any subnets.. Where are they?

Though I am not 100% on this I think the only subnets are in the southern enterance.

They extend something like 1.5 (From memory, maybee the enterance is only 1.5 I can't remember) from each side and leave a gap dead center.

Actually I have a screen shot.

Mark1 marks where I found the end of one of the nets. You can just make out that it is 1.4 km from the edge.

My lookout spoted the scapa flow lookout lights at 2.6 so I marked those distances down so that I know to be submurged between those points.

Sub nets came in patch 1.2 or 1.3 can't remember. Did u download those yet?

The path I followed was directly through the middle of the channel. As indicated, I didn't submerge fully but went in with decks awash - I was afraid of bottoming out and taking damage.

You should not worry about that unless you have really really bad weather.

When surfaced your draft is 5M. When you make a depth sounding it is from your keel. Thus 12 meters + 5 = 18 meters deep.

Submurged you usually sit at 12 1/2. That leaves 4 1/2 meters to play with.

With a surfaced depth reading of 12 you bottom out at 18. Deep enough that small ships like destroyers can pass directly over you and not hit. Just don't try to go under a Nelson BB!

Another way to find out for yourself is to run the SHIII Mission Editor, select "Open Scripted Layer..." and open file "Campaign_SCR" in folder Ubisoft\SilentHunterIII\data\Campaigns\Campaign.
Right-click on any ship symbol and select "properties" to learn in which moment of the war the ship will be around. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Just remember to make a backup file in case something goes wrong if you're tempted to change History. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

1st time I entered Scapa I went in at parascope depth and had the scope submerged. I went in real slow as not to alert the defences and spotted the end of the net just in time to back up a bit and go around it.

On the tactic of stopping engines to go silent around DDs, I use a slightly different technique:
I put the speed control in knots mode and drag the needle so the RPM gauge in the control room indicates 100 RPM. At this speed (early in the war) hunters have to be right over you with their engines stopped to hear you and you can continue to manouver and make some progress through the water. Depending on the sub type, you would make something between 1 and 2 knots at this setting. Make sure you make this setting AFTER giving the run silent command. The silent command will reset the speed to ahead slow (typically 3 knots.)

A variation of the 7 meter awash technique is to use 6 meters in rough weather (7 knots wind or more.) This setting still provides some stealth but keeps the boat from submerging ocassionally thus shutting down the engines for a few seconds.
