The PBS science series "NOVA" plans to broadcast a documentary presenting evidence that a torpedo fired from a Japanese midget submarine may have struck the USS Oklahoma during the Dec. 7, 1941, attack on Pearl Harbor.
Parks Stephenson was the lead investigator of an underwater expedition for the series.
Stephenson says there are accounts that indicate one torpedo fired at the USS Arizona was a dud, but he believes another torpedo hit the USS Oklahoma.
He says two submersibles belonging to the Hawaii Undersea Research Laboratory found three sections of the sub over the past few years in an area south of Pearl Harbor.
"Killer Subs in Pearl Harbor" premiers Jan. 5.
