According to SIPRI, Australia is the fourth largest importer of major weapons in the world. The US supplied 60 per cent of Australia's imports and Spain 29 per cent. All armed services have received new major arms in 2014–18, but mainly aircraft and ships. The F-35 combat aircraft and antisubmarine warfare aircraft from the USA made up 53 per cent of Australian arms imports in 2014–18, while ships from Spain accounted for 29 per cent. Large deliveries for additional aircraft and ships are outstanding.
