I agree we need the heavier loadouts for the B5N2, and the D3A as well.

Please add them HTC!

Mitsu,

I have searched high and low on the internet to see if there is any explanation on how the torpedo sight was implemented/used.

Do you have any literature or explanation on how that gadget works and would the one represented on the "kate" in AH actually be of some use ?

Thanks and <>

Yes, I was looking for the same thing myself.

 I admit the material on Kate torpedo bombing in the help forums is more a coincidence than an  explanation on how the sight actualy worked. It is admittably a coincidence that the place marked with the number "40" corresponded to actual 45 degrees torpedo run... and ditto with the rest of the numbers.

Kweassa ...

I sense some sarcasim in your post. My inquiry here is not meant to insult you or invalidate your hard work, so please don't take it that way.

If you have valid documentation showing that your proceedure is how the sight is actually used, then please post where you got it. I understood everything that you explained, but there was no mention in your post as to what the significance of the "white bar" was. What is it used for ?

I was asking Mitsu, due to the fact that he seems to have a vast amount of information on any/all Japanese aircraft.

Slap, why would you think so?

 No intent of sarcasm anywhere 100%

 I'm as curious as you are on how the sight really works, and I've been trying to search for whatever pics and information I can find on how it worked. Gee, if I stated the previous post in anyway that sounded like a sarcastic response, I'm sorry m8. No such intent! :)

Didn't think that was your style. :D

So Mitsu ... the ball is in your court now !!!

this site has a nice pic of the type 97 sight:

http://www.sam.hi-ho.ne.jp/ki-44/english/data/sight-en.htm

this show it in a kate:

http://www.wwiitech.net/main/japan/aircraft/b5n/

i could not find any information on its use either, though it appears to be more complex, Kweasa, than your tutorial shows.  

I thought the front bar might contain a mirror, that when dialed to a desired attack bearing, would reflect the pipper at an offset to target the ship. dunno though.

Hi Kweassa,

>Yes, I was looking for the same thing myself.

Here's some (sketchy) information on Western torpedo sights:

From what I've read, the torpedos had a mechanical analog computer that was fed with the target ship's relative course as well as with its speed. Just before release, the pilot (or torpedo aimer) would flip a switch to compensate for the target's manoeuvres (if any), indicating whether it turned at him or away from it (switch centre position was for targets running straight :-)

The computer also required advance setting of the torpedo's speed and (I think) also of the release range.

I'm not sure whether special sights were used for aiming torpedos, but my impression is that the aircraft just flew straight at their targets using their usual reflector sights.

(This information is from memory while I'm trying to recall Dunstan Hadley's "Barracuda Pilot" and a Jet + Prop letter to the editor. The Jet + Prop letter featured a photograph of the command unit of a German torpedo computer that seemed to have all the features Hadley mentioned for the British system, too. The neat thing about the German system was that relative course was set by turning a knob in the shape of a little warship :-) The Luftwaffe must have its share of reverse-course shots during excercises, I bet! :-)

By the way, I believe Hadley also mentioned that they had a converted instrument flight simulator (certainly the "Link Trainer") that served as visual torpedo bombing simulator.

Hi Mitsu,

>6 x 60kg HE bombs (KATE could have up to 7 60kg bombs, but it's little used)
>6 x 30kg HE bombs (up to 7)

Do you have a good source for that load out, or a technical drawing showing how it was carried? Thanks in advance!

Thanks, but the pictures don't load (at least for me). Could there be a problem with the links?

Hi Mitsu,

>Can't you download them?

No, "can't establish connection to server".

Pretty strange as I can see all the other pictures you posted.

Hi Mitsu,

>Changed upload server.

Thanks a lot, I got the pictures now! :-) Great, just what I had been looking for!

>6 x 60kg HE bombs (KATE could have up to 7 60kg bombs, but it's little used)

Do you mean 7 saw little use, or 6 saw little use as well?

Henning (HoHun)
