RO, RO, RO your boat: IJN Sub War

[bobogoboom]

ORIGINAL: John 3rd

I hold that if I can get a 1-for-1 sinking ratio of Jap SS to Allied ship, then I have done OK.  Allied ASW is just so terrible that you don't stand much of a chance.  This is how I use them:

1.  Glen I-Boats are used for heavy scouting purposes.  I also use them around major ports to spot Allied TF moving around.

2.  Ro are good point defense.  Use them to protect islands that I expect are going to be invaded or raided.

3.  Other SS are used to patrol major shipping lanes and/or highly congested areas.

I change nearly every Japanese SS Skipper at the start of the war to get more attacks and agression out of the vessels.

hmmmmm. Thanks for the pointers[:D]

Interesting Responses, thank you. Most important, almost nobody has acheived a clean hit on an undamaged USN capital ship. The 2 damaging attacks on Saratoga, and the sinking of Wasp, are difficult to replicate. (not to mention the sinking of Yorktown, but she was severly damaged).

Overall, sub results in the game are MUCH less for both sides compared to the actual war -

No one i know of has come close (in WITP) to matching the actual USN record of sinking Japanese capital ships and cruisers with subs.

Yeah. I hit yorktown as it was trasiting back to port from a raid on kwajolan. i also hit hermes as it was leaving celyon and i also nailed dorsetshire as she was leaving cyleon and also one cl in my game against john.

also in my game against chicago dorsetshire was torpedoed and badly damaged by a ijn sub as it was in the middle of the ocean in a cvtf.

After performing proper recon (i.e. lurking for about 1 year) I decided to join the forums [8D]
 
I think there's probably 1 more IJN sub to add to USS Batfish kill list - officialy credited as I-41, could've been RO 115 though.
 
That would've been be quite a score - 3 subs sunk within 3 days[:D]

[Panther Bait]

That was probably the one I was thinking of. I know it was something I read in Morrison's History of the USN, so it would have been written in the 40's/50's.

The claim is highly questionable according to Japanese Submarine Losses to Allied Submarines In World War II - by Vernon Miller page 35 - it was apparently a premature explosion.

[rtrapasso]

Same reference list I-174 probably sunk by USS Seahorse 20 April 1944.

EDIT: I-23 was sunk by Tautog on 26 April 1942 (p9)

REDIT: RO-49 was possibly sunk by USS Lagarto 24 Feb 1944
RO-46 was possibly sunk by USS Sea Owl 17 April 1944 (p41)

[rtrapasso]

OK - here is the list from the above reference sorted as to subs - a couple have been added and i've mentioned the ones that the author says didn't happen:

I-4 sunk by USS Seadragon p14
I-23 sunk by USS Tautog p9
I-28 sunk by USS Tautog p11
I-29 sunk by USS Sawfish p30
I-34 sunk by HMS Taurus p24
I-42 sunk by USS Tunny p26
I-43 sunk by USS Aspro p25
I-64 sunk by USS Triton p13
I-73 sunk by USS Gudgeon p7
I-122 sunk by USS Skate p43
I-162 sunk by USS Thresher - NOPE
I-166 sunk by HMS Telemachus p29
I-168 sunk by USS Scamp p21
I-174 sunk by USS Seahorse p27
I-183 sunk by USS Pogy p28
I-351 sunk by USS Bluefish p44
I-364 sunk by USS Sea Devil p34
I-365 sunk by USS Scabbardfish p35
I-371 sunk by USS Lagarto - NOPE
I-373 sunk by USS Spikefish p45
RO-30 sunk by USS Tautog - NOPE
RO-46 sunk by USS Sea Owl p41
RO-49 sunk by USS Lagarto p39
RO-112 sunk by USS Batfish p37
RO-113 sunk by USS Batfish p38

EDIT: notice that the sub sunk by Lagarto was apparently RO-49 not I-371.

Not to steal the thread but...
 
Did Japanese subs had any success against Allied ones?
 
The only one I am aware of is the sinking of the Soviet L-16 by I-25 in Oct 42 approx. 500 miles west of Seattle. L-16 was being transfered along with L-15 from Russian Pacific Fleet to Northern Fleet. Intended route was Dutch Harbour, San Francisco, Panama Canal, Canada and the United Kingdom. However there were some Soviet claims (esp. during the Cold War period) that L-16 was actually sunk by USN S-class submarine.

USS Kete was possibly sunk by RO-41
USS Corvina was sunk by I-176

I've had reasonable success in my game with Yava. I don't have the specifics to hand, but IIRC despite several HK groups patrolling my usual patrol areas I've managed to sink a minelayer and several transports around the Pacific islands, and sank two AO between Hawaii and the US West Coast. I've lost one I-boat with a few more returning home for moderate damage. Success against warships has been limited to hitting damaged DDs so far.

Go on...[;)]

The problem with sinkiing allied ships is that it helps the allied player. He has so many that there are too many decisions to make.[;)]

I was talking about the 'usual patrol areas'[:'(]

[Q-Ball]

OK, Last question on this. Does MANEUVER matter at all actually in Sub Combat?

The big IJN Cruiser subs have long range, and fairly fast, but are ungainly beasts, and many were withdrawn from service fairly quickly. The KDBs, on the other hand (I-173 and such), in game terms have shorter legs and are less useful, but are more nimble, and in actual fact were much more successful. Is this difference modelled in the game?

[Lecivius]

I came across this as I fished for info, tips, and advice in my 1st PBEM...and I took the Jap side so I need ALL the help I can get.  Game is stock & patched.
 
Last night, Decmeber 13 1941, aproxximatly 240 miles ENE of Pearl, the I-15 put 4 (count em, 4) torpedos into the Lexington.  She didn't sink outright, and I have yet to get the turn from my opponent to see if she still floats.  None of the escorts so much as got off a depth charge.
 
I guess even a blind squirrel gets an ocasional acorn [:D]

One thing I've never seen is a sub attacking another sub...does this ever happen in WitP?

No - i think they might try to put in in AE, though.

Did Sub vs. Sub ever actually occur in WWII?

As good is my memory, it occurs a few time, in Atlantic, and even less often in pacific, but it occurs. A old movie (of the 70's ??) is about a duel of a US sub versus a Jap sub, but i don't remenber the title. And it was about a true story.
Also read a book of "storys of WWII" talking of such a duel. But can't remenber the title also; sorry.
But i'm sure that it occured.

Well, sorry, i should have read the other post, my post came a bit late and totally innefective [:D]
