Utilizing a remote controlled submersible nearly three miles below the surface of the Atlantic Ocean the United States Navy has identified the doomed cargo ship El Faro — according to Navy official Christopher Johnson.

The sub — the CURV 21 — has a video camera and was working in tandem with the USNS Apache. With sonar, search crews thought they found the 790-foot behemoth boat over the weekend, but couldn’t positively identify that it was indeed El Faro.

The CURV 21 is still searching for the ship’s data recorder.

Under “optimal conditions”, its mission is expected to last about two weeks.

More from CNN:

The 40-year-old U.S.-flagged El Faro was headed to Puerto Rico from Jacksonville, Florida, and went missing near the Bahamas on October 1 with 33 people on board.

The owners of El Faro said the captain had a “sound plan” to avoid Hurricane Joaquin, but the ship’s main propulsion failed, stranding the crew in the path of the Category 4 storm.

The ship’s 28 American crew members and five Polish nationals are all presumed dead. One body was found during a Coast Guard search of the sea surface in the days after the ship disappeared.

For nearly a week, helicopters, planes, as well as Coast Guard and private ships scoured the Atlantic Ocean for signs of the ship.
