Joining a decommissioned destroyer and a former harbor tug, which already make up an artificial reef off of the coast of Delaware, is a 320-foot-long ferry.

The ferry, the former MV Twin Capes, which is part of the Cape May-Lewes fleet, was submerged 26 miles from the Atlantic coastline. The ferry is the most recent addition to the artificial reef — called the Del-Jersey-Land submerged reef — designed for the purpose of promoting a healthier marine habitat by providing an “enhanced habitat” for fish.

First launched in the 1970s as a passenger ferry and then later as transport for vehicles, the ferry hasn’t been in operation since 2013.

Watch the accompanying video to see officials intentionally sink the ferry.
