T2 vs. T3

[rudewarrior]

Just a question about the actual torpedoes.

I understand the history of development of the two torpedoes.

What I am trying to find out is if a T3 is just a retrofitted T2, i.e. a T2 with a new depth-keeping device and some other minor changes to accomodate, or is it completely revamped, i.e. a new torpedo altogether.

All the data seems to point to them having the same range and capability, so I am curious if it was a retrofit or redone.

If a retrofit, maybe it should have been called a T2.1?

I kill myself sometimes.

The T3 was basically a T2 with overhauled detonators. There was a variant of the T3 that increased the maximum range to 7500m (up from 5000m), but to my knowledge, the top speed was always 30kts.

I thought so. It seemed from everything I read it was really a retrofit. The biggest giveaway to me was just how easily it went into production after the new depth-keeping modification. Just seemed like they fixed that aspect and then it pretty much came right online.

Thanx for the confirmation.

Thanks for posting the links. Looking at the T1 those range numbers look different to those used in SH3/GWX. Regarding the T5 is it modelled in SH3/GWX that the torpedo could home in on the u-boat that fired it? Even though I've played for many years I've never got that far in a career to use a T5 hence the reason for my question!

I've not got access to the mod files on this system atm so I honestly can't answer....perhaps a read of the manual or some other kind soul can answer but I'm at work now until tomorrow afternoon.

I am at work too, but I have access to v1 of the GWX manual. I did a quick scan but couldn't spot any technical data relating to torpedoes.

Torpedoes settings in GWX are quite inconsistent. GWX merged T3 torpedo properties (1943) with torpedo T2 (1942), when its properties almost did not differ from T3. Should be used for parameters T2 from 1939 or 1940 when the torpedo was not pre-heated nor had improved batteries. Therefore, such parameters that were in the SH3 were more consistent with history - 3km@28kts.
This is not the only GWX problem with the torpedo parameters.
- T3 FAT II from 1943 have 7,3km@30kts range but newer model T3 LUT II from 1944 with small simpler homing mechanism and improved batteries have merely 5km@30kts in GWX. And we know that homing torpedoes had slightly larger range because of the use of improved batteries, which are also used in the model T3 later war (Maximum range of later war T3 with improved batteries was ~7,5km).
- The strength of acoustic torpedo head is the same as torpedoes T2 and T3, although T4 and T5 torpedoes contained 200 kg of hexanit instead of 300 kg.

Once I made myself small package of restoring the historical parameters of torpedoes:
1939.01 T1: no change (12,5km@30kts, 7,5km@40kts, 5km@44kts)
1942.10 T1 FaT: no change (as above)
1944.03 T1 LuT : no change (as above)
1939.01 T2: 3km@28kts, standard detonation
1942.06 T3: no change (5 km@30 kts, standard detonation)
1943.03 T3 FaT2: 6,4km@30kts, standard detonation
1944.09 T3 LuT2: 7,3km@30 kts, standard detonation
1943.07 T4: range and speed no change, 2/3 detonation strength
1943.10 T5: range and speed no change, 2/3 detonation strength

They come from the actual German data, not from the testimony of prisoners. British and U.S. data include a maximum range of torpedoes, and not the effective range at which the torpedo moving with constant speed. Only a constant speed allowed to hit in accordance with the calculations. While the maximum range of variable speed was significant at the attacks on the convoys with FAT and LUT torpedoes.
That is why the game should set the maximum ranges with variable speed for torpedoes FAT/LUT (14/8/6km for T1FAT/LUT, 6/7km for T3FAT/LUT), and maximum effective ranges at a constant speed for the remaining torpedoes (12,5/7,5/5km for T1, 3/5km for T2/T3).

I always wondered why the Wren-II homing torpedo was modeled in the game instead of the T3a. The ZII was never used in combat as far as I can tell... but the T3a was used from early 1944 on.
