The U.S. is prepared to sell $1.15 billion of armored vehicles to Saudi Arabia, the Defense Department announced on Tuesday.

Saudi Arabia has asked to buy the M1 Abrams tank, built by General Dynamics, and the Heavy Equipment Recovery Combat Utility Lived Evacuation System, or HERCULES, armored recovery vehicle, built by Bowen McLaughlin York, as well as equipment, training and support. The State Department approved the possible sale and notified Congress on Monday, according to a release from the Defense Security Cooperation Agency.

"This proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security of a strategic regional partner which has been and continues to be a leading contributor of political stability and economic progress in the Middle East," according to the release. "This sale will increase the Royal Saudi Land Force's (RSLF) interoperability with U.S. forces and conveys U.S. commitment to Saudi Arabia's security and armed forces modernization."

Specifically, the Saudis have asked to buy 153 tank structures to convert to 133 Abrams tanks and 20 battle damage replacements. They have also asked for 20 HERCULES structures.
