War at sea is a unique form of warfare requiring new tactics and arsenal. We look at three revolutionary weapons: Greek fire, developed by the Byzantine Empire to fight back Arab ships; the cannon, used by the British Royal Navy to defeat Spain; and the torpedo, which dominated the seas during the World Wars. Join an international team of experts as they reinvent ancient formulas and follow 17th century construction plans to recreate weapons used in past sea battles and put them to the test.
