Forum:KB:Song of War Larger than normal Hapan Battle Dragon?

In the Hapan Battle Dragon article, the flagship Song of War is described as an "oversized Battle Dragon", with no direct citation given. However, the article for Song of War itself lists it as 500 meters, the same as other Battle Dragons, with no mention of it being larger than others of her kind. The Song of War article is clearly citing the stats of a normal Battle Dragon, but does anyone have any idea where this claim of Song of War being larger comes from? Perhaps mentioned in passing in The Courtship of Princess Leia which was missed in the Song of War article?
