While Saudi Arabia is an important partner in the Middle East, U.S. lawmakers have criticized Riyadh for its involvement in the war in Yemen, a conflict considered one of the world’s worst humanitarian disasters. They have refused to approve many military sales for the kingdom without assurances U.S. equipment would not be used to kill civilians.

The Pentagon notified Congress of the sale on Thursday. If approved, the deal would be the first sale to Saudi Arabia since the Biden administration adopted a policy of selling only defensive weapons to the Gulf ally.

The State Department had approved the sale on Oct. 26, a spokesperson said, adding that the air-to-air missile sale comes after “an increase in cross-border attacks against Saudi Arabia over the past year.”

Raytheon Technologies makes the missiles.

The sale “is fully consistent with the administration’s pledge to lead with diplomacy to end the conflict in Yemen,” the State Department spokesperson said in a statement. The air-to-air missiles ensure “Saudi Arabia has the means to defend itself from Iranian-backed Houthi air attacks,” he said.

After the Trump administration’s friendly relationship with Riyadh, the Biden administration recalculated its approach to Saudi Arabia, a country with which it has severe human rights concerns but which is also one of Washington’s closest U.S. allies in countering the threat posed by Iran.

The package would include 280 AIM-120C-7/C-8 Advanced Medium Range Air-to-Air Missiles (AMRAAM), 596 LAU-128 Missile Rail Launchers (MRL) along with containers and support equipment, spare parts, U.S. Government and contractor engineering and technical support.

Despite approval by the State Department, the notification did not indicate that a contract has been signed or that negotiations have concluded. (Reporting by Mike Stone and Patricia Zengerle in Washington; Editing by Rosalba O’Brien and Dan Grebler)
