Masts removed from bomb-laden WWII ship in Thames in bid to avoid explosion
A dangerous wreck in the estuary
The SS Richard Montgomery sank in 1944 in the Thames estuary, carrying approximately 1,400 tonnes of munitions. Its masts remained visible above the water near Sheerness. The ship’s exact cargo is not known. A defence agency report estimated that its three holds contained almost 300 blockbuster bombs weighing 2,000lb each, as well as more than 2,000 cluster bombs.
Why the masts were removed
Officials were concerned that the masts could fall onto the ship and trigger an explosion. Ministers said removing them has made the wreck slightly safer. Mather said the masts placed significant strain on the structure. He said their removal reduced that risk and helped support the site’s long-term safe management.
Work completed and masts delivered
The work was completed ahead of schedule and below its forecast cost of £9.5m. The masts have been delivered to the Historic Dockyard Chatham maritime museum. The delivery was described as recognition of the SS Richard Montgomery’s historical importance and its role in supporting allied forces during the second world war.
