This ship calls to mind the batwing shuttle flown by Kylo Ren in The Force Awakens, although it has four upright wings instead of two. We don't know where the Imperials are, or what the context may be for this battle, but it looks to be an ambush of some sort. The palm trees and shoreline make it almost seem like the Star Wars version of Pearl Harbor. That would make this the destruction of an important battleship.
