The U.S. Coast Guard said in a tweet at 11:48 a.m. ET that a remotely operated vehicle discovered a “debris field” in the Titan vessel search area.
“Experts within the unified command are evaluating the information,” the Coast Guard said.
Officials are planning to hold a news briefing at 3 p.m. ET.
If the sub is still intact, oxygen supply on the vessel has run out or has nearly run out.
