A training incident involving two hovercrafts this week off the Jacksonville coast injured 30 sailors and Marines.
The incident, about 100 nautical miles off the coast, involved a collision between two landing craft, air cushions — vehicles used for transporting personnel, weapons and equipment from ships to a beach.
Five of the 30 injured were transported to a hospital in Savannah for further treatment, the U.S. Navy said in a statement Friday. Four have since been released and one remains hospitalized for treatment.
The Navy did not provide a condition update for the hospitalized sailor. The sailors and Marines with minor injuries were treated at sea.
The Navy said both vehicles remained afloat and returned to their ships. An investigation into the collision continues.
Naval Station Mayport said no sailors or resources from Mayport were involved or responded.
The two landing craft, air cushions that were involved were from the USS Wasp and the USS New York. Both ships are based in Norfolk, Virginia.
