2013 DSEI: A force to be reckoned with
When the 2013 Defence & Security Equipment International (DSEI) that took place at the Excel exhibition centre in London from 10 to 13 September with claims to bring together the ‘entire’ defence and security, it is hard to argue otherwise. The biennial event attracted 1,500 international , suppliers from more than 50 countries, a larger number of international pavilions, including South Korea, Brazil, India, Australia, UK, USA and six new dedicated seminar theatres offering free educational sessions and showcases. There were specialised air, naval, land, security, medical and unmanned zones, expanded live waterborne and unmanned systems demonstrations and static vehicle displays for the land, air and naval sectors.
From semiconductors and PCBs through to tanks and naval vessels DSEI covered the complete Defence & Security sector and military uniforms mixed with business suits as attendees looked to source the latest equipment and systems, develop international relationships, and generate new business opportunities.
Being so vast and all encompassing there was the danger of needing night sights and a complex surveillance system to identify the products and systems relevant to the RF and microwave sector. However, as the synergies between electronic manufacturing and the defence industry have become increasingly apparent and important, the organizers created a pavilion dedicated to electronic manufacturing companies which are heavily involved with the defence and security industry, along with there being a considerable presence of electronics exhibitors across the show floorThe Association of Old Crows (AOC) Electronic Warfare Pavilion showcased electronic warfare capabilities in a dedicated area, while exhibitors specialising in the communications sector were also well represented.
