Big guns of Elizabeth's navy

The Elizabethan era of English history was in many ways a time of transition including in the area of naval warfare. The recent discovery of the wreck of a small fighting ship off Alderney in the Channel Islands offers proof that Elizabeth's navy had "created the first ever set of uniform cannon, capable of firing the same size shot in a deadly barrage."

"There's a very good chance this ship fought against the Armada with its revolutionary guns, but there's no proof that all or even some of the others were armed similarly," says Saul David, historian and presenter of a BBC Timewatch documentary about the guns.
