Minor tweaks to the carrier and the battleship sims. Navweaps indicated of the 12cm AA rockets that the "mountings were adapted from the 25 mm AA triple gun mounting" so I simmed additional 25mm mounts to reflect this. I also simmed the rockets by using the torpedo entry and used the number of mounts as planned for the Shinano. While messing around with another design, I thought I should do it this way...
... or maybe it was a bad idea to try it :-) .
Edit: minor correction to the miscellaneous breakdown of the two ships.
