I ran across this browsing YouTube and thought it may be of some interest. Someone in Japan computer-modeled the operation of one of the Yamato's 18-inch gun turrets and made quite an interesting CGI movie out of it. It steps through the different layers of hardware & infrastructure including train, elevation, the different steps in loading, firing, gas ejection, etc.. The textual overlay is in Japanese & there's music & sound effects but no narration. The movie is unique in that you get multiple different angles to view all of the hardware when it's in operation, unlike a regular training film. It looks somewhat similar to the USN's loading & firing process but naturally with variations.
