Mighty Ships: SEASON 3: EPISODE 4

USNS Grasp

On a mission to solve a mystery that is more than 230 years old, the USNS Grasp may have just taken on more than she can handle. This rescue and salvage vessel is searching for the USS Bonhomme Richard, a historic US warship that sank in battle in 1779. But the unforgiving waters of the North Sea and failing equipment threaten not only the mission, but also the lives of its divers. Will this Mighty Ship locate the missing wreckage or will brutal weather and failing equipment sink this historic mission?
