Brimstone locate 2 British bombs during UXO survey

Brimstone UXO was recently contracted to conduct a non-intrusive magnetometer survey on a site in west Kent. The survey, designed to detect buried ferrous objects, revealed a number of magnetic anomalies consistent with potential unexploded ordnance (UXO).

UXO target investigation and identification

Following the initial survey, Brimstone recommended a Target Investigation to determine the nature of the anomalies. Using precise GPS coordinates, Brimstone’s Explosive Ordnance Disposal (EOD) engineering team excavated the suspicious targets. The result: two 1000lb British bombs buried at depths of 5m and 5.7m.

The bomb casings confirmed that the munitions dated from the first half of the 20th century, raising concerns about a high explosive hazard. However, upon closer examination, Brimstone’s founder, Aaron Florence, identified the bombs as inert, concrete-filled training weapons rather than live explosives.

Preventing delays with expert identification of the British bombs

The ability to swiftly confirm that the bombs were non-hazardous eliminated the need for a Ministry of Defence (MOD) callout, avoiding unnecessary disruption to the project. Had the bombs been live, they would have required a full EOD disposal operation, potentially delaying the site’s progress. This case highlights the importance of expert UXO surveys and investigations in preventing costly delays and ensuring safety on development sites.

Why do inert training bombs end up buried?

During WWII and the early Cold War era, the RAF used concrete-filled training bombs to simulate real ordnance for pilot practice. These bombs matched the weight and aerodynamics of their live counterparts but lacked an explosive charge. Some were used on dedicated bombing ranges, while others may have been lost or abandoned in historically active areas.
