Quick Summary

Engineers removed the masts from the sunken World War II ship SS Richard Montgomery in the Thames estuary without triggering an explosion. The ship carries approximately 1,400 tonnes of unexploded bombs and has been under constant guard due to safety concerns. Maritime minister Keir Mather announced that removing the masts reduced structural load on the wreck and was completed ahead of schedule at a cost of £9.5 million. The masts are now at the Historic Dockyard Chatham, while monitoring around the ship will continue.

Story summary

Engineers have removed the masts from the SS Richard Montgomery, a World War II cargo ship sunk off Sheerness in 1944 with approximately 1,400 tonnes of unexploded bombs onboard, to reduce the risk of an accidental explosion. The operation was conducted due to fears that deteriorating conditions could cause the masts to collapse into the deadly cargo and trigger a major blast. While some experts predict a potential tsunami, debris up to 3km in the air, and destruction of Sheerness, others are cautious about the exact impact of such an event after over eight decades underwater. The salvaged masts have been moved to Historic Dockyard Chatham for display, acknowledging the ship's historical importance during World War II. Despite this work, the explosives remain in the wreck on the riverbed, continuing to pose a potential risk.

🔮 London’s mayor has called for a cap on the numbers of robotaxis on its streets, with the UK government poised to allow fully driverless vehicles to operate in the capital.
🔮 Work will close London’s Paddington station – affecting intercity trains to the west of England and Wales until January – as well as Birmingham New Street, the UK’s busiest station outside the capital, for five days over the holiday period.
🔮 Under the contracts that replaced the franchising system since the pandemic, train operators’ income comes from fees paid by the DfT instead of depending on fare revenue, with the taxpayer instead taking any profit or loss from ticketing income or refunds. Avanti, which is due to be taken into public ownership next year as part of Great British Railways, paid out more than £50m in 2025-26, and is expected to pay out more than £70m this financial year.
🔮 How could this happen?
🔮 A new railway station will be built in Bradford to “transform how people travel across the north”, the government has announced.
🔮 The work was carried out because of concerns that the masts, which had remained visible above the water near Sheerness, could collapse in on the deadly cargo and blow up the ship.
🔮 Disabled passengers will have better safeguards when flying, the government has pledged, including protection from damaged wheelchairs and support from trained staff.
🔮 The GMB and ADCU unions have both said thousands of drivers jobs will be lost and have called for help for those affected.

🔮 Non-EU citizens, including UK travellers and those from other visa-exempt countries including the US, Australia and Canada, will soon need to pay €20 (£17) for an electronic waiver to enter the Schengen zone under the European travel information and authorisation system (Etias).

Although the risk of an accidental major explosion is now deemed remote, local people have been alarmed by incidents in recent years, including the occasional close proximity of cargo shipping, and a paddleboarder who uploaded pictures to social media of himself leaning on the protruding masts.

that → remove → decades
The work was carried out because of concerns that the masts, which had remained visible above the water near Sheerness, could collapse in on the deadly cargo and blow up the ship. uncertain
