U.S. President Barack Obama's administration has offered Saudi Arabia more than $115 billion in weapons, other military equipment and training, the most of any U.S. administration in the 71-year U.S.-Saudi alliance, a report seen by Reuters has found.

The report, authored by William Hartung of the U.S.-based Center for International Policy, said the offers were made in 42 separate deals, and the majority of the equipment has yet to be delivered. Hartung told Reuters the report would be made available publicly on Sept. 8.

The report said U.S. arms offers to Saudi Arabia since Obama took office in January 2009 have included everything from small arms and ammunition to tanks, attack helicopters, air-to-ground missiles, missile defense ships, and warships. Washington also provides maintenance and training to Saudi security forces.
