How does the missing Titan submersible work? Here’s a look inside


The search for a missing Titanic tourist submersible continued Wednesday as experts feared the watercraft may have only a day's supply of oxygen left. 

U.S. and Canadian crews began searching for the vessel Sunday after the 22-foot submersible, Titan, lost contact with a support ship while carrying five people to the wreckage site of the Titanic.

Here’s a closer look at the Titan submersible owned by OceanGate, a Washington-based deep-sea exploration company.

How big is the submersible?

The Titan is about 9 feet high, 8 feet wide, 22 feet long and weighs 25,000 pounds, according to the OceanGate website. The watercraft left from St. John's, Newfoundland, on Friday and lost contact with the ship that was monitoring it about an hour and 45 minutes later. It usually takes two hours to descend to the wreck.

A CBS reporter who rode the Titan submersible last year told USA TODAY that parts of the vessel seemed "less sophisticated.”

"There were parts of it that seemed to me to be less sophisticated than I was guessing. You drive it with a PlayStation video controller ... some of the ballasts are old, rusty construction pipes," CBS correspondent David Pogue told USA TODAY. "There were certain things that looked like cut corners."

The submersible's exterior

The Titan is launched underwater from a platform. Submersibles require a support ship that can launch and recover them, unlike submarines, which are fully autonomous.

Interior of the Titan

The Titan fits five passengers inside the hull, including one pilot and four crewmembers. The hull is made of 5-inch-thick carbon-fiber materials.
