:I haven't seen Jackson's book, but I'm not inclined to think that it's better than Jentschura, Garzke and Dulin, or Skulski. I always prefer the more specialized books over more general surveys. The Treaty definition of standard doesn't include ammo or most reserve feed water for the boilers so the figures above seem way out of line. Sturton's book, which is also a general survey of battleships, quotes 62,135 standard and 69,990 full load, much more reasonable.
