I'm a little late reading this, but DM has the best answer :wink:. Conway's All the World's Fighting Ships 1922-1946 is the most accurate and complete reference that you can get. Jane's reprints are great for looking at, but due to their being "too close" to the time period, they lack in accuracy. Just for fun look in a 1945 Janes regarding the readout on the Yamato and you'll see that they "lost" over 25,000 tons. It's basically the specs on the U.S. Iowa class and an obvious "guess". Even knowing this, I still bought my reprint of the 1945 Janes to see what they sometimes didn't know, but it's still an ok reference. Conway's is very accurate and well researched, and also has quite a few ship's histories included.
