Anyway, I highly recommend the book.

British subs did get a TDC sometime during the war, certainly by late 1941. Officially it was know as the Torpedo Director or Torpedo Control Calculator, but it was always called the "Fruit Machine" (See
Unbroken by Alistair Mars). The main difference between the "Fruit Machine" and the TDC was that the "Fruit Machine" was not linked to the torpedo and all settings had to be passed by telephone and manually set. Despite this the Royal Navy achieved the highest "hits per torpedo fired" of all Allied Submarine Forces (see
THE UNDERWATER WAR, 1939-45 by Richard Compton-Hall).
