The extent of Australian taxpayer support for the US defence industry has become clearer from an analysis of major defence procurement data and current defence tendering.

The government has continued to attract criticism for its cuts to major defence procurement spending in the May budget, with former chief of Army Peter Leahy the latest critic to voice concerns. Last month US neoconservative and defence industry lobbyist Richard Armitage criticised the government's funding cuts. In May, the government announced spending cuts of $5.4 billion, with big reductions obtained from delaying or cancelling major procurement processes.
