SDD UK specialises in the production of inert copies of terrorist devices as training aids for accredited security organisations engaged in counter terrorist training and operations. Trading since 1990, in response to customer requests, SDD uses similar techniques when manufacturing the x-ray correct inert devices as terrorists may use in manufacturing lethal versions. To ensure accuracy of the replicas involves significant research and detailed design by the SDD design and development team. The range of products which are sold both within the UK and internationally include suicide IEDs, inert detonators, simulated explosives and a selection of target item training kits. All product order deliveries include an ‘Inert Certificate’.
