No one was hurt Sunday morning when a U.S. Navy guided missile destroyer and a large Japanese-owned merchant vessel collided near the Strait of Hormuz according to a statement released by the U.S. Navy.

The collision between USS Porter (DDG 78) and the Panamanian-flagged bulk oil tanker M/V Otowasan occurred at approximately 1 a.m. local time.

Overall damage to Porter is being evaluated, but the ship is able to operate under its own power.

The U.S. Navy says that the incident is under investigation and the collision was not combat related.

USS Porter is on a scheduled deployment to the U.S. 5th Fleet area of responsibility conducting maritime security operations and theater security cooperation efforts.
