Yes, it is a ship type, for conventionally fueled— Bunker Oil fueler, capable of ship to ship refueling under power, at sea.

They guy didn’t deserve murder. And it would have been very appropriate for Sen. Diane Feinstein to have been there- to honor the guy whose office she took advantaged by his murder. She is behind nearly ALL of the Spygate, btw. Especially as regards releasing the classified Senate Intel Committee hearing with her and hitlery’s pal, Glenn Simpson of Fusion GPS. She did that, and then... immediately handed over her seat on the committee to Sen. Warner (the most guilty of SPYGATE in re: Wolf’s leaking of FISA Warrant) in partnership with rino Sen. Burr (R-NC). Two dumber a@@es one could not find for such an important job.
