Blanchardstown-headquartered specialist engineering firm Innalabs makes incredibly hi-spec gyroscopes for unmanned aerial vehicles (UAVs) or drones, similar to those used to blast al-Qaeda targets in Afghanistan.
As well as the drones, Innalabs equipment is used for remote-control weapons systems, naval sight and turret stabilisation and other military purposes, according to the company's website.
The Russian-backed firm, which is controlled by a number of Cypriot holding companies, also has a research and development operation in Ireland.
Last week, Innalabs was one of two Irish exhibitors showing their wares at the annual DSEI 2013 Defence expo in London.
The world's leading arms manufacturers and defence contractors congregate every year at the event to display the latest developments in weapons technology and kit. Innalabs did not comment.
Ireland is developing an extremely sophisticated specialist engineering and technology industry, which has attracted overseas defence buyers. BAE spent €220m to buy Norkom Technologies two years ago, with engineering firms Timoney and Enterprise Ireland-backed robotic bomb disposal firm Kentree getting investment from global defence companies.
