above : WDAD U Class submarine

below : SH5 U Class submarine

why ? because there were two types !

http://en.wikipedia.org/wiki/British_U_class_submarine

here is upholder :

HMS Upholder

Armament: 4 bow internal 21 inch torpedo tubes, 2 external
10 torpedoes
1 - 3 inch gun

so should we make two types in WDAD ?

the model from SH5 is the first type with 6 bow tubes including 2 external

the model from WDAD is the later type with 4 bow tubes.

Well its nice and i love it to play 2 types.Around 1940-42 i would play SH5 U-class and later years(43-45) WDAD class
Its matter if any modder have time to put it in

I have started a patch for WDAD to originally change the type with SH5 model but now that I know there were two types ...

I will make a clone of the U Class and give it its SH5 name Undine.

So we'll have the T, two U, missing the S ;)

Keltos01,
In your SH5 U-class picture it has AA gun will it have any .50 cal or Vickers machine gun?

There should be a .303 machine gun, but here we'll settle for the .50

Nice camouflage Keltos ;)

The problem is that skippers either used 0 or 90, not intermediate angles. The british TDC could not update Gyro Angles "on the fly", instead they were set manually into the torpedo, and by default it was 0º. This is the reason why the captain asked for an attack course and the officer operating the TDC answered with the correct one. The Torpedo was not changed to aim at the target, instead it was the whole submarine what moved to aim at the enemy AFTER the captain had chosen the Gyro Angle he wanted to shoot with (Which was either 0 or 90º for simplicity purposes)!

In the sim right now the Torpedo's Gyro Angle is updated constantly, allowing you to shoot in any moment instead of waiting at the correct course for the precise angle, which is what british submariners did. And if they missed the exact moment to shoot their whole setup was ruined, something that won't happen right now because the Torpedo Gyro Angle will be updated by the TDC...

The problem is that we still need the TDC to calculate the lead angle for us, and it will not do it with a fixed angle torpedo, because in that case the Gyro Angle pointer becomes locked. We could use a printed table for easy 90º track angle shots, but that would mean that only being perpendicular to the target is valide for getting a correct solution, which is even more limited than what british submarines could do! And the utility of the TDc would be limited to somehow check the accurancy of your estimations. I'm afraid we are screwed :dead:

Hello Hitman and all,
I haven't played WDAD, but have been reading the thread because I had read a little about the "fruit machine" some time ago and thought it was very interesting.

I'm not sure how you want to model the fruit machine, but if knowing the lead angle for for firing is the only thing holding you up, I can help you out. I worked out the necessary equations for a zero gyro-angle firing solution since I like to play the S-boats this way (and a 90 deg. track is not required). Any calculator with trig functions will suffice.

rowi58 sent me the files, so maybe we could have two sides to this campaign ?

JU_88 and Ref 3d model

Adua Submarine (59 subs built)

Profondità operativa 80 m

Propulsione motore diesel da 1.400 CV

elettrico da 800 CV Velocità in superficie: 14 nodi (26 km/h)

in immersione: 7,5 nodi (13,9 km/h)

Autonomia 3.180 mn

Armamento siluri:

4 tubi lanciasiluri da 533 mm a prora
2 tubi lanciasiluri da 533 mm a poppa
1 cannone da 100/47 (152 colpi)
2 mitragliere singole da 13,2 mm (3.000 colpi)
6 siluri
Alcune unità furono modificate con l'aggiunta di 4 siluri a lenta corsa maiali

torpedoes :

Si otteneva una corsa di 4.000 metri a 50 nodi, o una corsa doppia riducendo la velocità a 40 nodi. Direzione (angolazione) e profondità erano regolabili prima del lancio. Un giroscopio garantiva che venissero mantenute durante la corsa. Il siluro aveva un diametro standard di 533 millimetri (450 per le versioni precedenti, più piccole) e una lunghezza tra 6,50 e 7,20 metri. La carica esplosiva era di 250-270 chili, attivata da acciarini universali a pendolo, ovvero azionati dall’urto contro il bersaglio.

Waiting from Elanaiba to see if we can actually use the U Class from SH5 without infringing on copyrights.

in the meantime I made doors for that particular boat :

I also removed the scopes and split the back plane from the hull as well as the bowplanes.

This is truly spectacular work guys. Well done! This mod seems to be building momentum daily.

The addition of more British submarine types, and indeed some Italian boats will add immensely to the depth of the Mediterranean campaign.

Don't forget that it wasn't just the U, S & T classes that took part in the war, but also the H, L, O, P, R & V Classes.

:arrgh!:

yeah yeah, but we need 3d models to implement those boats ;)

Hum hold on, let first the british side be ready :DL

Yes of cours an external program one can use by ALT/TABing the game can work, but the thing is we wanted to coax the US TDC into working like the british one did, it is only really a matter of finding a solution of the GA lock, but it eludes us still :hmmm:

modified the loadout picture to look more like the type I U class ;:

I set the caustics off..

still need to move dg and tower, but the rest is ready !
