ADS Northern Ireland (NI) is the trade organisation for the aerospace, defence, and security sectors in Northern Ireland. Launched at the Farnborough Airshow in July 2010, the organisation works closely with and is supported by InvestNI to grow and ensure the continued success of these vital industries in Northern Ireland. ADS NI's priorities are to help member companies develop, to increase market share and to raise awareness of NI capability and technology internationally.

ADS NI brings together leaders from the major aerospace, defence, and security companies and the Universities to collectively set the direction for the Industry. The team is led by Ian Watson, Director, ADS NI and Scotland, chaired by David Beatty of Thales UK and managed by Dr Leslie Orr, ADS NI Manager.
