World of Weapons

War at sea: a new form of warfare with exceptional challenges. In this episode, weapons expert Stephen Bull tests three significant weapons of the sea. The Byzantines guarded the Greek fire as the secret super weapon that kept Constantinople safe for over 800 years. Experts build an original replica for an experiment that will demonstrate the thunderous force of a ship cannon. One of the most devastating missiles ever invented is the torpedo, and a subsonic torpedo might be ruling sea battles in the future.

Attacking the enemy in an ambush is a devastating advantage at war. The Ambush explores weapons that stayed undetected until their very strike revolutionized warfare. The caltrop brought down the cavalry when it made entire battlefields impassible. Being able to load and fire a rifle from a lying position made a huge difference during warfare. The insidious landmine weakens every leftover moral of the enemy's army. What if future soldiers' cover becomes invisibility?

Wars become even bloodier as new technologies keep evolving. An international team of experts tests the deadliest weapons upgrades in the history of warfare. Designed to penetrate solid armor, the Scorpio makes use of the power of torsion. With the long sword, European knights slaughter their opponents on the medieval battlefield and Henry's rifle changed future wars with a revolutionary design: the lever action. Looking forward, a futuristic image of a combat robot army can be the next generation of infantry.

Often times civilians suffer from waging a war - in this episode, experts track down three weapons that were used to recklessly attack civilian populations. With no regard for civilian casualties, the trebuchet hurls heavy stones against solid castle walls. Deploying biological weapons is a chance to conquer a fortress without destroying it. Designed to put an end to World War II, the atomic bomb embodies fear and terror to this day. Now, a cyber war could be most devastating, affecting everyone's reality.
