Saint Jalmack ship which literally has the same design looking from the back as those ones.
Marines ships don't fit this design. As i said in another thread if Oda wanted to show us that the marines are in Wano they would do that through Drake, not Lucci and the CP0 which also brings the fact...
These are not marine ships, they are ships from the World Government which are two separate entities.
The Marines rightnow are dealing with the Shichibukai, so rather than Oda not paying it looks like you are the one doing it xD
