A massive Mexican navy tall ship on a goodwill visit to New York slammed into the Brooklyn Bridge late Saturday, toppling its huge masts into the deck in a horrifying scene that left 19 injured, including four critically, according to fire officials and sources.

The majestic Cuauhtémoc — which has a crew of 277, mostly cadets — apparently lost power as it was sailing out of New York on its way to Iceland and the current carried it into the road deck of the bridge around 8:30 p.m., according to Mayor Eric Adams and footage of the crash.

The collision sheared off the ship’s 147-foot masts. Adams said two sailors were on top of the mast when it hit the bridge, which has a max clearance of 135 feet.
