This is a call-out to the latest SBY 2199 movie (or SBY 2202). There's a number of posters for the 2202 movie that have Yamato in a state of rebuilding (or maybe mid-scrapping) that look like this.
Space Battleship Yamato lacks the Chrysanthemum Seal in the front of her bow - there's just a hole there (like on this image).

From what I understand, the scene associated with this is awesome.
