Unexploded shell unearthed at historic coastal gunnery range

A member of the public recently discovered an old unexploded shell at Wembury Point, Plymouth. Recognising the potential risk, they contacted the authorities, prompting a response from Royal Navy Explosive Ordnance Disposal (EOD) engineers. The team safely removed the projectile and later destroyed it in a controlled explosion.

How was the shell disposed of?

When dealing with unexploded ordnance (UXO), Royal Navy EOD specialists follow strict safety protocols. Wherever possible, they avoid transporting live ordnance, as moving unstable explosives can pose significant risks. Instead, small to medium-sized items like this shell are typically disposed of in a controlled explosion at a safe location nearby. This method ensures minimal risk to both the public and the environment while swiftly neutralising the hazard.

Why was an unexploded shell found here?

Plymouth has a long naval history and is home to HMNB Devonport, the largest naval base in Western Europe. Wembury Point itself was part of the down-range area for the Royal Navy Devonport Gunnery School Range. Given its historical use for artillery training, it is unsurprising that UXO contamination still occurs in the area today.

This particular range was a seaward firing range, meaning live rounds were fired towards the open water. However, the unexploded shell in question does not appear to have reached its intended destination, nor was it thrown during the firing process. It is likely that it was discarded near a former gun battery at some point in the past and subsequently became buried over time.

The ongoing risk of historic UXO

Discoveries like this highlight the ongoing risk posed by unexploded ordnance left behind from military activity. Even decades after their intended use, these items can remain highly dangerous. Corrosion, shifting ground, and environmental factors can make UXO increasingly unstable over time, making professional assessment and disposal essential.

The best way to assess the potential risks of UXO on any site is through a Brimstone Stage 1 Preliminary UXO Risk Assessment. Our expert analysis identifies whether a site is at risk of UXO contamination based on historical records, previous military use, and known UXO finds in the area. This proactive approach ensures safety for both construction projects and the general public.

UXO marine capabilities

Brimstone UXO also specialises in marine UXO risk management. Coastal and offshore environments are particularly susceptible to UXO contamination due to historic naval activities, shipwrecks, and dumped munitions. Our team provides comprehensive marine UXO surveys, risk assessments, and clearance operations, ensuring safe access to seabed areas for marine construction, dredging, and renewable energy projects.
