Congressional report shows that arms exports tripled from previous year, with Gulf Arab states the main customers.

US weapons sales more than tripled in 2011, reaching a record high, according to a new congressional report.

The country sold $66bn worth of arms last year, up from $21.4bn in 2010. The previous record had been $31bn in 2009; global arms sales declined slightly after that because of the economic crisis.

America’s largest customer was Saudi Arabia, which purchased more than $33bn worth of weapons from the US, including dozens of F-15 fighter jets, missiles, and other materiel.

The United Arab Emirates and Oman also both spent billions, purchases driven in part by fears over Iran’s regional ambitions. The Obama administration has touted these deals as a major stimulus for the US economy, saying the Saudi arms sales alone would generate some 75,000 new jobs.

The US also arranged several multi-billion dollar deals with Asian nations, including an agreement with China to sell transport planes worth more than $4bn.

All told, the US sold 78 per cent of the world’s arms in 2011. Russia was a distant second, with $4.8bn in arms sales.

The report was prepared by the Congressional Research Service, which conducts studies for US lawmakers.
