Maddy

can you equip it with a homing torp ? that would be historically accurate against IJN subs..

This was indeed a hush hush top priority project during the WWII, my former father in law worked on it and the proximity anti aircraft shell,and also developed some of the first effect sound speed theory for sonar. I dont know details about use in the pacific but i do believe they did use it there....that will be another question i wll ask that retired USN officer here who is the guy who i mentioed to you was ComSubPac...see if he knows.

Thanks Admiral !
I am sure they used them in the Pacific, I have seen that data somewhere here... wait...

but by all means do ask the USN officer !

keltos

could we randomize the torpedo ? meaning only once in a while you get a mk 24 ?

I have read about homing torpedos used fairly regular basis in the PTO with good results.Used more in the ATO but Allied ASW was more active in the ATO.

I would love to see homing torpedos from planes(enemy subs if possible) in later years of IJN campaign.However, hope they will not be 2009 era smart bombs that ALWAYS hit.

Something I would like to see are plane dropped depth charges that can explode down to say 250-300 feet.

Ah, can't wait for this mod

The following is from "US Navy Torpedoes" by Frederick J. Milford:

"340 [Fido] torpedoes [were] dropped in 264 attacks of which 204 were against submarines. In 142 attacks US aircraft sank 31 submarines and damaged 15; in 62 attacks against submarines other Allies, mainly British, sank six and damaged three. Most of these submarine sinkings were German U-boats in the Atlantic, but five Japanese submarines were sunk by Fidos, one, I-52, in the Atlantic and four in the Pacific. OEG Study No. 289, 12 August 1946, is the main source for this conclusion."

I heard there was in the Altantic Op Theater a 1 ton depth charge that had been used against subs : one dd would creep and listen, one would move on top of the target sonar off and drop the DC !

Mark X DC... Quite an interesting weapon

http://www.navweaps.com/Weapons/WAMBR_ASW.htm

keltos01 · 10-28-09, 01:27 AM

interresting data too :

Mark VII Heavy .

Date Of Design N/A

Date In Service 1940

Total Weight 420 lbs. (191 kg)

Explosive Charge 290 lbs. (130 kg) TNT

Sink Rate / Terminal Velocity 16.8 fps (5.1 mps)

Settings 300 feet (91 m) max

Notes: This had a 150 lbs. (68 kg) cast-iron weight attached to increase the sinking rate. The British claimed this DC would split a 0.875 inch (22 mm) hull at 20 feet (6.1 m) and force a submarine to surface at about twice that distance. A minol charge introduced in 1942 increased these distances to 26 feet (7.9 m) and 52 feet (15.8 m), respectively.

Mark X, X* and X** .

Date Of Design 1941
Date In Service 1942

Total Weight 3,050 lbs. (1,383 kg)

Explosive Charge 2,000 lbs. (907 kg) TNT

Sink Rate / Terminal Velocity
Mark X: 6 fps (1.8 mps)
Mark X*: 21 fps (6.4 mps)
Mark X**: 50 fps (15.2 mps)

Settings
Mark X: 220 feet (67 m)
Mark X*: 640 feet (195 m)
Mark X**: Depths down to 1,500 feet (457 m)

Notes: Intended for launching from a 21 inch (53.3 cm) torpedo tube. The slow sinking speed of the Mark X was so that the launching ship could get clear of the explosion. In 1943, the Mark X* was introduced. This had a faster sinking and deeper depth setting intended to combat the deeper diving U-boats that were becoming more prevalent. In 1945, the even faster sinking Mark X** was developed for use against the newer, deeper diving U-boats, but this version was not introduced into service, as the ahead throwing weapons had obsoleted it.

but how can we make the game chose different dc ? I thought there was one for all type only ?

Hi Maddy !

keltos01 · 01-02-10, 08:58 AM

any news ?

AOTD_MadMax · 01-03-10, 07:20 AM

Sorry Mate,

not yet !
We from AOTD are very busy in the moment with upcomming Onlinecampaigns in SH3 / SH4 and IL II !

I will work it out when i got enough time for it.

Let's just make a US Minelayer to mine all Japanese harbors and get it over with. We can save fuel, so we don't sail 1000 miles to get blown up.

the way things are going japan might just lose the war

keltos01 · 01-03-10, 12:44 PM

actually the Air Force did use B-29's to drop mines on japanese harbors, thus earning quite a few sinkings !

But if you read Orita's I-Boat Captain you'll notice that the submariners did indeed achieve quite a lot.
