German bomb encountered during drainage works near former army base

An unexploded German bomb from World War 2 has been unearthed at a site in Bordon, Hampshire, during drainage works on Hogmoor Road. The discovery was made by contractors working on the SANG (Suitable Alternative Natural Green Space) drainage project. The bomb, believed to be a remnant of wartime bombings, was discovered buried in the ground and posed a significant risk to workers in the area.

Upon the discovery, a 200-meter exclusion zone was immediately established around the site as a precautionary measure. The area was secured while an army explosive ordnance disposal (EOD) team assessed the situation. Due to the complexity and potential danger of the device, the bomb could not be safely defused and was destroyed in a controlled explosion. The team also constructed a “blast igloo” using 300 tonnes of sand to safely contain the explosion.

This incident highlights the ongoing risks posed by unexploded ordnance (UXO) in areas with a history of military activity. Even decades after the end of World War 2, UXOs continue to pose significant threats in both rural and urban environments.

Identifying the UXO at Bordon: the SC50 and other bomb types

From the photograph provided, it appears that the weapon encountered at the Bordon site was an SC50 bomb, a 50kg high-explosive bomb that was commonly used by German forces during WWII. However, it is possible that the device was a 41kg or 34kg incendiary or high-explosive bomb, as these smaller bombs used the same casing size (SC50) as the standard 50kg bomb.

The SC50 bomb was a high-explosive munition designed to cause significant damage upon detonation. It was widely used by the German Luftwaffe and was typically dropped during air raids aimed at military and industrial targets. Incendiary bombs, like the 41kg and 34kg versions, contained thermite or magnesium compounds that created intense fires upon impact.

The discovery of such devices is not uncommon in areas that were heavily targeted during the war. Bordon Camp, a large army base during WWII, was known to be a strategic target for the Luftwaffe. The base would have been easily visible from the air due to its size and strategic importance. Anecdotal evidence suggests that the Luftwaffe raided the base multiple times during the war, and as a result, the area remains at risk of UXO encounters.

The importance of UXO risk management and safety

The discovery of unexploded bombs like this one emphasises the importance of effective UXO risk management, especially in areas with a known history of military activity. Construction projects, drainage works, and land development in these areas require careful planning and risk mitigation strategies to ensure the safety of workers and the public.

UXO risk management involves several key steps, including risk assessments, surveys, and investigations. It is essential to identify areas that may be contaminated with UXO before any construction or excavation work begins. By working with specialists who have the necessary expertise and equipment, the risks posed by UXOs can be mitigated, ensuring that projects proceed without incident.

Stay safe: reporting and dealing with UXO

If you encounter a suspicious object that may be a UXO, it is crucial to treat it with caution. Never attempt to move or tamper with the device. Instead, follow these steps:

• Evacuate the Area: Clear the immediate vicinity to ensure that no one is in danger.
• Establish a Safe Zone: Create a secure perimeter around the suspected UXO.
• Contact Authorities: Notify the local authorities or emergency services, who will contact the appropriate explosive ordnance disposal (EOD) team to handle the situation.
• By following these steps, you can help reduce the risks associated with unexploded ordnance and protect yourself and others from harm.

Why UXO risk mitigation is crucial for your project

As the UK continues to deal with the legacy of World War 2, unexploded ordnance remains a real threat, particularly in areas that were heavily targeted during air raids. Proper UXO risk mitigation is essential for ensuring the safety of workers, the public, and your property. Whether you are involved in construction, excavation, or land development, Brimstone UXO can provide the expertise and services needed to manage and mitigate these risks effectively.
