Browsing TAKIs site I have found this in FAQ:

Q:

The ships (Landing Craft carriers) "Shinshu Maru" and "model Ko" and submarine "Maru Yu", did have IJA or IJN officers?
A:

As for the landing craft carriers, crews were civilians and they were hired by the IJA. The crews for the guns and landing crafts were IJA soldiers.

The crews of the "Maru Yu" were IJA soldiers. They were mainly converted from tankers.

So, what happens, when ship "nationality" is set to IJ Army? I am guessing the only difference will be different possible "Captains"?

Speaking of which. Is there only 10 Maru Yu in-game? According to wikipedia, seems 38 were completed. And at least another 15, should be due in late 1945.
Also, it seems they capacity is too generous. To keep with in-game model, they should have 36 person, and 12 cargo capacity, which gives them exactly "24 tons freight or 40 troops".


Similar change could be applied to Type D submarine, which is listed as 65 tons of cargo in hull, and 25 in upper deck (so maybe 25 cargo, and 195 personnel? Seems high. Maybe 25 liquid?).
Anyway, wikipedia shows them armed with 2 torpedo launchers, while in-game they have no torpedoes.

In the game CA-30 Houston has a captain K.I. Riker as commanding officer. If I am not mistaken her real-life skipper on Dec 7th 1941 was captain Albert Howard Rooks - he is not even in the database. [/align] [/align]PY-10 Isabel starts the game at Manila. IRL on Dec 7th (8th in the PI) she was at sea on her way back from her "defensive information patrol" between Cam Ranh Bay and Manila.[/align] [/align]In the game Isabel also carries depth charges as part of her armament. According to Winslow: "The Fleet the Gods Forgot: The U.S. Asiatic Fleet in World War II" Isabel had no anti-submarine weapons at the outbreak of the war. On Dec 10th she was at Cavite preparing to install depth charge racks when the Japanese bombing raid obliterated Cavite Naval Yard.[/align]

From DAFS

"Equipped with a home-made depth charge rack constructed by the ship's crew, Tulsa now boasted an antisubmarine capacity and began escorting merchantmen along the south coast of Java to Tjilatjap, the only port on the island still out of reach of Japanese bombers. While engaged on convoy duty in late February, Tulsa received orders to proceed to a point 300 miles to the south of Java. En route, she learned that her mission included searching for survivors of Langley (AV-3), sunk on 26 February 1942. When she arrived at the scene, however, she found only traces of wreckage, but no survivors. Unbeknown to Tulsa, Langley's survivors had already been rescued by Whipple (DD-217) and Edsall (DD-219).

After this apparently fruitless rescue attempt, Tulsa came upon the scene of the sinking of British merchant ship City of Manchester. Whippoorwill already had begun rescue operations, yet needed medical facilities which Tulsa had on board. The gunboat hove to and assisted the minesweeper in the lifesaving, then returned to Tjilatjap where she awaited instructions, ready for sea at a moment's notice.

With Java being rapidly encircled by the onrushing Japanese, orders to retire were not long in coming. On 1 March 1942. Tulsa, Asheville, Lark, and Isabel (PY-10) crept out of Tjilatjap, bound for Australia. While the other three ships steamed resolutely onward, Asheville soon developed engine difficulties and fell behind, only to be trapped and sunk by superior Japanese surface forces.

Tulsa and her two companions arrived in Australia waters shortly thereafter. They were the last surface ships of the Asiatic Fleet to survive the Japanese onslaught in the East Indies ; and they escaped, by a hairsbreadth, the fate which befell Asheville.

For the seven months following her arrival in Fremantle, she engaged in routine patrols off the Australian coast before being refitted at Sydney in October 1942. Here, she received British ASDIC, degaussing equipment, Y-guns, and 20 millimeter Oerlikons. Thus outfitted, she served once again as a convoy escort, occasionally towing targets as well."

So we can see two refits
Say: 1/42 Adding Dept charges - DC Rack /Mk 6 DC 1x R Ammo 6 = equal to Bird Class Minesweeper

Say: 6/42 Refit
Change .303cal Lewis MG to x2 20mm Oerlikon AA Gun RS and LS Ammo 18
Change DC Rack / Mk 6 DC to Y-Gun Mk7/Mk6 DC x2 RS/LS Ammo 6

These two refits would make the Asheville and Tulsa effective ASW escorts.

Thoughts / Comments better sources?

Ignore this post, I was wrong in my error report.

It seems, that in IRONMAN Scenario not all Submarines have their Torpedo Tubes split.

US seems to be OK, but some Dutch, and UK subs still uses their old configuration.

Hello

Blackhorse wrote that I should post it here see here

Some leader will never be accessible in game because they where wrong flaged. I belive this is a mistake because why should someone create a leader for nothing?


Leader 14051 Sprague, Thomas L. He is a Radm but flaged as „05 - Ship“. Because that there are never Radm selctable for ship`s (highest Rang is Captain) and leader which are are flaged as „05 -ship“ could never selected as a Task force commander I suggest to re flaged him as a „04 – Task Force“.

The same problem for e.g. McMorris, Chas H.; Number 12359. In Scenario 28 he is Right now he is classified as "type: 05-ship". So if u remove him (maybe by accident) he seems not to be accessible because he has a rank of an Rear Admiral.
Would it be better to give him the "type 04 Task Force" or "Type 01 Headquarters" like Leader Mitscher, Marc A?
Mitscher`s Number is 12510 and he is used as a ship commander but is internal a Task Force leader.
In WW2 McMorris was a ship Commander, Task force Commander and Chief of Staff of the Pacific Fleet.

There are also some Leader which have the same Problem
Number:
9009
9010
9311
10158
12359
14051
14052

P.S. I did not look at the axis side.

I suggest simply to reflaged them all to type “04 - Task Force"

Maybe Leader 16376 Erskine should be reflaged as “02 – Large Ground Unit”

Omat

I have seen several RADMs commanding Japanese tankers in WITP, so it is possible AI can choose this rank, if there is shortage of captains.
But obviously, this is not solution, we are looking for [:D]

A friend of mine suggested that a portion of Japan's existing merchant fleet, at the start of the war, were left out of the game to represent those ships dedicated to domestic purposes as opposed to those in the game towards the "war effort". I don't ever recall seeing this. Does it sound familiar?

Buck

Yes, I've seen this discussion before too. It seems logical as much traffic took place between China and Japan. I believe there was also some discussion about including them back in a variant of the "DaBabes" scenarios.

Wow, I posed this question on February 16 and had pretty much resolved it wasn't correct. Must have gotten lost in the mail.

Does the game simulate the mid 1943 arrival of US torpedoes with larger warheads?

21" (53.3 cm) Mark 14
Explosive Charge
Mod 0:  507 lbs. (230 kg) TNT
Mod 3:  668 lbs. (303 kg) TPX
This was the standard submarine torpedo of the World War II period

Mod 3:  801 lbs. (363 kg) TNT or 823 lbs. (373 kg) HBX

The M6A1 Seiran is a float torpedo bomber that comes on some of the late war japanese subs. Problem is, the squadrons don't seem to have torpedo capability on the subs - the "Torpedo" for the armament is red. I'm guessing because there are no torpedo sorties on the subs (if subs can even have torpedo sorties).

Is this the intended result? Or will it launch torpedoes even if the torpedo ordnance is red?

Looking in the database, it seems the torpedoes have the larger warhead from the start. However, the database makes no distinction for the type of explosive. According to Navweaps.com, Torpex and HBX have about 50% greater effect than TNT. The Japanese Type 97 explosive had about 7% more force than TNT.

There is TK Moji Maru at Guam Invasion TF, however there is no fuel at Chichi-Jima, so it remains empty (not even mentioning, that TF is docked at lvl 1 port).
What is more important, I have found, that Tanker Moji Maru was actually registered as AO, and was taking part as support of Hong Kong operation, and struck a mine in January 1942, and sank.
This ship have sunk date set in 1944, and in fact, there is mention about Moji Maru sunk at that date around Truk, but it was supposed to be transport, not tanker.


Also few overlookings of TFs:
8004 Kuching Cbt TF (*). It is supposed to cover invasion TF (you can see it in editor), but this invasion TF is empty, and 8004 just returns to Cam Ranh Bay.

8120 Manado Invasion, and
8121 Ternate Invasion
have no destinations set. Maybe they should stay in port, but if not, it can mess historical first turn seting.

Also, it seems, that BB Mutsu should be at Hiroshima/Kure, not Tokyo, because it was at Hashirajima on 3rd December:

3 December 1941:
Undocked. Returns to Hashirajima. Anchors in readiness condition.

8 December 1941: Operation "Z" – The Attack on Pearl Harbor:
BatDiv 1's MUTSU and NAGATO sortie from Hashirajima to the Bonin Islands with the First Fleet's Bat Div 1, BatDiv 2's ISE, HYUGA, FUSO and YAMASHIRO, light carrier HOSHO, escorted by light cruisers OI and KITAKAMI and eight destroyers.

This should probably also include Yamashiro, which starts game in Yokohama.

It would be actually beneficial, if game would allow to define weapon upgrades in database. Considering number of modifications Allies got on their projectiles. Currently you have to make whole class upgrade, to use new weapon.

Couldn't this be at least partly simulated by having class upgrades with delays, damage, and required shipyards set at zero? Seeing as the vessels with torpedoes are mostly fairly small, the upgrade wouldn't require particularly large ports.

Yes, that seems to be simplest solution, however I have discovered, that there are additional damages, when upgraded classes have diiference in some statistics. For example:
- if there is difference in speed, engine will be damaged
- if there is difference in durability, there will be Sys damage

So, I am not sure, if changing weapons, do not damage them completely, and would need weapon repair. And torpedo tubes need large Shipyards to do it.

I don't think that is the case, but I've never tested it. Incidentally, I believe that differences in durability result in floatation damage, not system damage.

I have seen this only during my testing of Shinano conversion, so I can not be sure.

I am actually wondering if it is possible to get ship sunk this way:
it gets floatation damage, lots of system (it is conversion after all), then some unlucky roll, and it sinks in docks [:D]

Yeah, I do remember having meetings where we decided just what to screw up for people like you. So glad to know you are on top of it.
