In Summer 2005, a mysterious submarine is discovered off the coast of Italy at 120 metres deep. For Lorenzo del Veneziano, an underwater marine archeologist, it is an amazing sight. The submarine is intact! It stands almost vertically at the bottom of the sea, it's hull stuck in the sediment. What is the story of this ship, why is it here? By uncovering the mystery of its origins we will retrace the incredible story of U-455, a German warship that fought every marine battle against the Allies, from the Baltic Sea, to the Atlantic and then finally the Mediterranean where it now rests. An extraordinary underwater adventure and an ambitious historical investigation.
Today's submarines are vast, billion-pound, high-tech monsters with a nuclear payload that can level cities. But the story of Britain's first submarines began over a century ago, with inventors risking life and limb in a range of bizarre contraptions. Sir Tony Robinson joins forces with expert diver and historian Innes McCartney to uncover the experimental origins of Britain's Submarine Service, through a series of wreck dives, underwater blast tests and hands-on demonstrations. At the start of the 20th century, Britain lagged far behind Germany in developing these new weapons, but by 1914 they had caught up, in an underwater arms race that would play a vital role in World War I. Now underwater archaeology in the English Channel is shining new light on this story. This Time Team Special reveals how information revealed by Innes's dives and the team's experiments is helping to map the successes and failures of the submarine pioneers.
Precocious Oliver struggles with being popular in school but when a dark-haired beauty takes interest in him, he's determined to become the best boyfriend in the world. Meanwhile, his parents' already rocky relationship is threatened when his mother's ex-boyfriend moves in next door.

Unlike other theatres of war the world of the submarine infamously nicknamed "the hidden hunter", has long remained shrouded in mystery, its vessels more complicated that a space shuttle, and the water they hide in less explored than space. The covert missions of a submarine are kept top secret and notoriously guarded by the MOD and Royal Navy…
At 171 m long, the USS Pennsylvania is the biggest submarine in the US Navy. It can dive deeper than a thousand feet, sail for 20 years without refueling, and remain submerged for up to 6 months. The vessel carries a crew of 155 men and a deadly nuclear arsenal. This film explores how this submarine was made possible through a series of six historic engineering breakthroughs. The film explores the inner workings of six landmark submarines, including the tiny Turtle and colossal German U-Boats. Each features a major technological innovation that allowed engineers to build bigger and bigger submarines.
