Facing an increasingly diverse and complex portfolio of threats from unpredictable, often anonymous enemies, those responsible for defending national security are progressively calling upon the expertise of those from 'crossover' industries. Advances in critical technology from the automotive, IT, communications and medical sectors have become particularly pertinent in recent years, as militaries seek innovative solutions to the latest challenges posed by modern warfare.

Defence & Security Equipment International (DSEI), the world leading exhibition for air, land and sea applications of defence and security products and equipment, will provide an influential forum to examine the pioneering skills and technologies that are currently being developed in other sectors and applied to defence. A biennial event, DSEI takes place at ExCeL London from 10-13 September 2013.

The high-performance electronics and engineering skills demonstrated in motorsport have long been adapted for use on the frontline. From airbags to generators and data systems to unmanned systems propulsion technology, much of what is developed for military purposes today derives from the automotive industry's established expertise.

While maintaining its focus on traditional platforms and equipment, DSEI will also highlight the advanced technological manufacturing base found in other industries -providing a broad range of companies with a valuable platform to present their products to customers not just in the UK but from key markets around the world.

Following a successful introduction at the last event, the Motorsport Pavilion at DSEI 2013 will provide an important focal point of the potentially life-saving technology that this sector offers the defence industry. Drawing on the fast turnaround techniques employed by motor racing teams, for example, can guide the development of high performing equipment for Urgent Operational Requirements. The Pavilion will be held for the second time in partnership with the UK's Motorsport Industry Association (MIA).

With its long history of developing and embedding advanced hard ware and software solutions for the automotive industry and expertise in wireless technology, Elektrobit, also provides vehicle power and data systems to optimise the performance, efficiency and safety of military and special vehicles. Derived from its heritage in motorsport, the company has adapted its traditional technologies to suit international military requirements. The range of solutions includes tactical telephony products such as the EB Tough VoIP Field Phone and the EB Tough VoIP Desktop Phone, and the Tactical Wireless IP Network communication system, recently procured by the Finnish Defence Forces.

Making its debut at DSEI 2013, CTrukhas rapidly established itself as the market leader for the provision of twin-hulled, composite vessels for the offshore wind sector. Currently, it is building a lightweight and fuel-efficient 11m fast-reaction and interceptor catamaran (Twin Hulled Offshore Raider) with enhanced performance for defence/maritime security/coastguard and similar missions. A version of this model is scheduled to feature as part of the popular DSEI Waterborne Demonstration programme, which will prove a key feature at this year's event.
