Why is the SS Richard Montgomery Still Full of Bombs

The SS Richard Montgomery is a sunken World War Two Liberty ship in the Thames Estuary that still contains roughly 1,400 tonnes of live explosives, and this video explains why the British government has never removed them. The ship grounded on the Sheerness Middle Sandbank during a gale in August 1944 while carrying munitions bound for Cherbourg. Salvage crews removed about half the cargo before the hull cracked and the ship broke in two, forcing them to abandon the operation. Eighty-two years later the wreck still sits in 49 feet of water about a mile and a half off Sheerness, its masts breaking the surface, guarded around the clock inside a 500 metre exclusion zone. This video examines the blast models, the unresolved expert dispute over whether the cargo is inert, the historical precedent that made the government choose inaction, and the delayed mast removal project now scheduled to begin. What's covered in this video: The Richard Montgomery was a standard Liberty ship built in Florida in 1943, welded together cheaply and designed for a service life of just five years. On 20 August 1944 a force eight gale dragged its anchor and grounded the vessel on the Sheerness Middle Sandbank while it carried nearly 7,000 tons of munitions bound for the French port of Cherbourg. Salvage teams successfully unloaded about half the cargo before the weight of the remaining bombs and the shifting sand cracked the welded steel, splitting the ship in two and flooding the holds. Roughly 1,400 tonnes of high explosive ordnance remain trapped inside the forward section today, in 49 feet of water about a mile and a half off Sheerness. Port authorities monitor the site 24 hours a day using radar, cameras and patrols to enforce a 500 metre exclusion zone beside a major shipping lane outside London. Government blast models indicate a mass detonation would shatter every window in Sheerness and generate a wave between four and sixteen feet high, surging toward the Kent and Essex shorelines and up the estuary toward the Thames Barrier. The energy release is frequently compared to the 2020 Beirut port explosion, with the added factor that the wreck sits directly in the approach to one of Britain's busiest shipping channels. Liberal Democrat MP Julian Huppert called a proposed Thames Estuary airport a "bonkers idea" on the grounds that underwater construction work could disturb the unstable hull. The Maritime and Coastguard Agency and successive ministers have maintained the risk of a catastrophic explosion is remote, reasoning that most of the cargo is TNT and that the fuses have degraded after eighty years in saltwater. Annual structural surveys between 2010 and 2019 described the hull as broadly stable and supported the hands-off policy. Professor David Alexander of University College London argues that cutting the masts is a superficial gesture and that the bombs need to be removed before it is too late. A recent sonar survey found the deck plating on the port side near hold three has begun to collapse, with damage that appears fresh. The video traces the government's caution to a 1945 salvage attempt on the SS Empire Heritage off Southampton, during which several hundred tons of ammunition detonated and destroyed the dockyard. Fully clearing the explosives would require evacuating Sheerness and surrounding coastal towns, an order no politician has been willing to authorise. Officials settled on cutting down the three deteriorating masts so they cannot collapse onto the cargo holds and trigger a chain reaction. The mast project was first announced in 2020 with a five million pound budget, then repeatedly delayed and rebudgeted to nine and a half million pounds. After Resolve Marine was appointed to lead the removal, sonar sweeps detected eighteen unidentified metallic objects buried in the mud within fifty metres of the hull. Explosive ordnance disposal experts suggested the objects could be dropped depth charges, lost salvage equipment or loose bombs that slipped from the holds, and the agency chose to leave them in place rather than risk disturbing them.
