In a move critics warned could empower the Saudis to manufacture their own high-tech weaponry for use in their assault on Yemen, the Trump administration reportedly wants to allow the American arms giant Raytheon to work with the kingdom to construct bomb and missile parts inside Saudi Arabia.

As The New York Times reported Friday, President Donald Trump’s emergency declaration last month greenlighting billions of dollars in U.S. weapons sales to Saudi Arabia without congressional approval contained a provision that permits Raytheon to “team up with the Saudis to build high-tech bomb parts in Saudi Arabia.”

The provision, according to the Times, immediately “raised concerns that the Saudis could gain access to technology that would let them produce their own versions of American precision-guided bombs—weapons they have used in strikes on civilians since they began fighting a war in Yemen four years ago.”

“The move grants Raytheon and the Saudis sweeping permission to begin assembling the control systems, guidance electronics, and circuit cards that are essential to the company’s Paveway smart bombs,” the Times reported. “The United States has closely guarded such technology for national security reasons.”

In a detailed investigation published last month, In These Times found that the Saudi kingdom has “ordered more than 27,000 missiles worth at least $1.8 billion from Raytheon alone.”

“About $650 million of those Raytheon orders,” In These Times reported, “came after the Saudi war in Yemen began.”

William Hartung, director of the Arms and Security Project at the Center for International Policy, warned that handing the Saudis the capacity to develop high-tech bombs on the level of U.S. weaponry could have disastrous consequences for the people of Yemen, who are already suffering from the world’s worst humanitarian crisis.
