About Portsmouth

Software Development for Portsmouth's Defence & Space Technology Sector

Portsmouth's economy is shaped by its deep connection to the Royal Navy and a growing technology sector anchored by Airbus Defence & Space and IBM. HMNB Portsmouth is home to the UK's two Queen Elizabeth-class aircraft carriers, sustaining a defence supply chain worth hundreds of millions of pounds annually. Airbus's Broad Oak facility designs and builds satellites for military and commercial customers, making Portsmouth a centre for UK space manufacturing. IBM's Cosham campus and the University of Portsmouth's computing department provide additional technology depth. The city's compact island geography and waterfront lifestyle attract young professionals, and the Lakeside North Harbour business park offers modern office space with easy access to the M27 and M3.
