The British military traditionally dominated Gibraltar's economy, with the naval dockyard providing the bulk of economic activity. This, however, has diminished over the last 20 years and is estimated to account for only 7 per cent of the local economy, compared to over 60 per cent in 1984. Today, Gibraltar's economy is dominated by four main sectors: financial services, online gambling, shipping, and tourism, which includes duty-free retail sales to visitors. The territory also has a small manufacturing sector, with one company (Bassadone Automotive Group) supplying ambulances and other project vehicles converted locally from SUV vehicles to the United Nations and other agencies, employing some 320 staff across its range of activities.
