It seems that there is some reason(=mechanisms betweem Accuracy and Range) but I cant find it. Any ideas about it?

Hi. Alfred.

I appologize that I used the words are misleading and inappropriate. What I really want to ask is "Is there anything to consider when I modify the figures(Accuracy and Range, penetration and Range) of Torpedoes (or Naval Guns)."

For example, DBB and Original have different Accuracy fugures of Type93 Torpedoes. But I failed to find 'the reason why this happen' and "any debate or account about the 'correlation between Accuracy and Range'(or correlation between Penetration and Range)" in forum.

So I want to know about the "Correlations" and "The way to use and calcurate it"

Been a lurker more than a poster for most of those discussions but I recall at least one comments (from Simon I believe) who mentioned nerfing the 'Long Lance' for reasons that they modeled and felt more reflective of the DBB game mod. The change is intended as are the many changes they made to air frames as well.

I am playing two PBEM games (Stock Scenario 2 and Relutant Admiral 8.1 which uses a lot of DBB as the basis) and I can see a very noticable differnce in the early Japanese sub attacks, more misses, and a few more hits-no explosions.

I did a few searches without any luck so far.
I would look for his post in the Design and Moding sub folder back about 2-3 years ago.

Either very few or none of the IJN subs used the Long Lance IIRC.

Note from John (Symon, or JWE, if you are looking for references).

"Didn't nerf any one side. We don't do that sort of thing. All torpedoes, of every nationality, had data fields recalculated and adjusted to better fit within the 'mean' of calculation expectation values. There were way too many +2 and +3 sigma results, and proportionately more +1 than -1. Judicious math was indicated. Every torpedo, of every nation was run through the exact same math model to give self-consistent results. The 61cm type-93 might have 'smaller' specs in Babes than stock, but so does everything else. Proportion remains. The 61cm type-93 is still more powerful, to exactly the same degree, than others.

Please tell the IJ fellow that the editor device screen is nothing but a GUI window that hosts gobs of info from a universe of devices, land, sea, and air. Data fields have an arbitrarily assigned "LABEL" that means nothing except to identify the variable a particular code piece is looking for. Correlation depends on the particular code subroutine for a combat modality. That is the heart of the game system and cannot (will not) be revealed. This sort of thing is what Babes was all about; self-consistent centering of data across multiple combat modalities such that they 'fit' within expectation values of the code."

Range and duds were not changed afaik.

Long Lance was 1000kg heavier.

Submarine torpedo Type 95 was also O2+Kerosene like Long Lance so that is not the reason. Reason is probably exclusively the size/weight that is an increase of more 60% weight, 650mm instead of 533mm diameter. The weight implications is more than just the torpedos and reloads weight, since means also stronger torpedo tubes and handling devices to cope with more 60% weight.

Yes it a well known case that one of Chikuma class cruiser was probably saved because the commander choose to jettison the torpedoes just before a bomb hit precisely in their place.

quote:

Six Japanese cruisers were sunk due, at least in part, to fires and/or explosions among their oxygen torpedoes.

6 June 1942: Mikuma is hit by bombs, fire breaks out among the torpedoes, torpedoes explode, ship sinks. (Sister Mogami, also bombed that day, has already jettisoned her torpedoes and survives.)

11 October 1942: Furutaka hit by American naval gunfire at night, fires almost immediately break out among her torpedoes, illuminating the ship, apparently drawing more gunfire. Ship is sunk.

3 April 1943: Aoba is hit by bomb from a B-17, torpedoes explode, ship is beached to avoid total loss. Later salvaged.

25 October 1944: Mogami hit by two American 8-inch shells. Fire breaks out, she collides with Nachi (her third collision of the war), then her torpedoes explode. She is bombed and torpedoed again by American aircraft, and finally must be scuttled.

25 October 1944: Suzuya is missed by bombs, but fragments from near misses ignite fires among her torpedoes, torpedoes explode, ship sinks.

25 October 1944: Abukuma is hit by 3 bombs dropped by B-24s. Fires detonate 4 Type 93 torpedoes, ship sinks.

I was referring to loss of CA Chokai, Takao-class. One hit by a five inch shell and the mounted Long Lances exploded, taking out propulsion and steering, leaving the ship ripe to be sunk.

Sorry i was reinforcing your point with another situation but reading my post again appear i could have been disputing your cruiser ID


This is the situation i was referring to:
Battle of Santa Cruz(From Wiki)

On 26 October 1942, 250 miles (400 km) northeast of Guadalcanal, Rear Admiral Hiroaki Abe's task force launched seven floatplanes to scout south of Guadalcanal. They located the American fleet, and Abe followed with an attack which sank Hornet and damaged the battleship South Dakota and cruiser San Juan. However, Chikuma was attacked by a Douglas SBD Dauntless dive-bomber from Hornet, and quick thinking crewmen jettisoned her torpedoes seconds before a 500 lb (230 kg) bomb hit her starboard forward torpedo room. She was also hit by two other bombs, destroying one floatplane on the aircraft catapult. Chikuma suffered 190 killed and 154 wounded including Captain Komura.
