The twentieth century has seen global conflicts in which command of the oceans would be vital in securing victory. Ground-breaking technological developments would see the aircraft carrier supplant the battleship as the most powerful maritime ship of war and change naval combat forever. But many of these ocean titans were to become victims of the conflict, destroyed by gunfire, torpedoes, and bombs with catastrophic loss of life. Many now lie as wrecks on the ocean floor, whilst the final resting place of others remains unknown.

This engrossing eight-part series tells the stories of these remarkable warships from key conflicts that now litter the seabed. Through never before seen archive, exclusive interviews and insightful analysis we will uncover the secrets behind these amazing ships, explore their power and, through the stories of the people who served aboard, examine the spectacular actions that led to their doom.
