Can you imagine having found one of the most famous shipwrecks in history and not being able to talk about it? Robert Ballard can. Ballard was the lead oceanographer for a fact-finding, top-secret Navy mission in 1985 and he helped discover the Titanic.

But How Did the Navy Find It? And Why Did it Take so Long for Anyone to Talk About It?

Well, the answer to the second question is simple. No one talked about it because the mission was top-secret. Scant details managed to make their way to the surface in the mid-1990s, but the Navy neither confirmed nor denied them. So there wasn’t anything concrete to go on, and most people chalked up the idea that the Navy discovered the Titanic as a conspiracy theory.

Then James Cameron’s 1997 blockbuster Titanic hit the silver screen, and there was a renewed interest in what kind of role the Navy had played in the shipwreck’s discovery. Despite the renewed interest, the Navy kept a tight lid on any PR about the shipwreck.
