Mast Removal Begins on WWII Wreck SS Richard Montgomery

Resolve Marine, a global marine-solutions provider, has started cutting and lifting the three steel masts from the SS Richard Montgomery, a World II Liberty ship that sank in the Thames Estuary in 1944. The work follows extensive technical assessments and independent expert review, and is being carried out under strict safety and engineering protocols to protect personnel, nearby communities and maritime traffic.

The vessel went down during a storm in August 1944 while carrying Allied munitions destined for Europe. The wreck lies about 80 kilometres (? 50 miles) east of London and remains one of the UK’s most closely monitored shipwreck sites. Approximately 1,400 tons of unexploded munitions are still on board, and the mast tops have long been a visible landmark for local visitors. After a failed salvage attempt that was halted when the wreck cracked, the UK Department for Transport appointed Resolve Marine in April 2026 to undertake the current mast-removal project.
