So there's a statement in Friedman's Naval Firepower that Italian firecontrol was based on imported Barr & Stroud tables (just like Japanese) and I have recently seen this repeated elsewhere. However, I have also ran across a statement online that it was based on tech imported from Hazemeyer which itself was associated with Siemens, so the Italian FCS was essentially a kind of earlier version of the German one.
There are few incidental features in Littorios that seem to support the latter claim. First of all, the vertical shelf-like firecontrol computer looks absolutely nothing like the British and Japanese FC tables and seems more akin to the German one. Secondly there is a small AC power generating capacity and it's tempting to conjecture this supplied power for the FCS, yet the British model would have only needed DC power.
Anyone know more about this?

Anyone know more about this? I have a book on Google books titled " The Littorio Class, Italy's last and largest Battleships" by Emingo Bagnasco. I will examine it for answers. So, Far, on page 155-157 he discusses 'firing table' , defining them and providing information on their structure as to differences in average elevation and such. There is no reference that their were based on Barr & Stroud. He state that in an early period the Italian optical industry reproduced British and German models but around 1928 they were domestically -designed and built but that is the only reference. |

I have that book myself as physical copy, quite examplary single class work too. Indeed the book is part of the reason I feel the Hazemeyer theory is more likely since the system doesn't feel British influenced at all (compare to Japanese LA systems which are unmistakably "British"). |

Unfortunately these seem to be for earlier variants, but the early '20s variants seem to have been similar to British AFCT. I have seen a pictures and diagrams of Nagatos, supposedly similar, LA table and it looks very little like the Littorio's. |

You might need to find some Italian documentation that could help. I would just go with Friedman. Bye. |

I note that Friedman mentioned in _Naval Firepower_ that Italy gave Germany fire control system information in 1931. So is the influence running both ways?
