Remains of Libery Ship.

 The Royal Navy is set to dismantle the masts from a sunken World War II wreck carrying 1,400 tons of unstable explosives, which sank off the coast of Kent in 1944.

The SS Richard Montgomery was a US Liberty Ship, which ran aground in August 1944, and despite frantic attempts to remove its deadly cargo, its hull cracked and sank off Medway in Kent. 

It is now feared that an explosion could cause a 15ft high tsunami tidal wave and cause 'mass damage and loss of life', according to a new report by the Ministry of Defence.
