In the brand new series of Mega Movers, we follow the relocation of the largest, heaviest and least mobile historic structures imaginable. In this episode, we reveal how ships frequently have to be deployed to move other ships. We observe the crucial planning process, explaining how skilled aquatic Mega Movers have to pay detailed and close attention to size, weight, weather and clearance.

If the world’s largest aircraft carrier - the 1,092 feet USS Ronald Reagan - came under enemy attack and was crippled at sea, there would not be a ship big enough to rescue it and move it back to America for repairs.

It would be the toughest ship transport challenge ever undertaken. In an extraordinary display of muscle-power and engineering, Mega Mover theorists design and build the largest heavy-lift submersible vessel ever constructed. It will be able to lift the ship of the water and haul it halfway across the world.

As war rages in the Middle East, the American Naval fleet is in increasing danger of being destroyed by enemy deep-sea mines. Orders are issued to move a 224-foot long, 1,300-ton minesweeper halfway around the world - quickly. It is a job that can only be done by using an enormous heavy-lift ship to move this mighty war ship.
