Note.—The Japanese fleet has mainly been armed by Armstrong’s Works, but the “Katori” was armed by Vickers', and those ships taken from the Russians during the late war are armed with guns from Krupp or Obuchoff. Guns of all sizes are now, however, being constructed in Japan, so that the country is no longer dependent on foreign factories.
