Saudi Arabia and the United States signed on Tuesday the largest defense sales agreement in history, worth nearly early $142 billion, as President Donald Trump visited Riyadh.

The agreement will provide Saudi Arabia with state-of-the-art warfighting equipment and services from over a dozen US defense firms, said a White House statement.

The sales that the US intends to complete fall into five broad categories: air force advancement and space capabilities; air and missile defense; maritime and coastal security; border security and land forces modernization; and information and communication systems upgrades.

The package also includes extensive training and support to build the capacity of the Saudi armed forces, including enhancement of Saudi service academies and military medical services, added the statement.

“This deal represents a significant investment in Saudi Arabia’s defense and regional security, built on American systems and training,” it stressed.

“Our defense relationship with the Kingdom of Saudi Arabia is stronger than ever under President Trump’s leadership, and the package signed today, the largest defense cooperation deal in US history, is a clear demonstration of our commitment to strengthening our partnership,” it said.

“The agreement opens the door for expanded US defense industry participation and long-term sustainment partnerships with Saudi entities.”

“The deepening United States-Saudi Arabia partnership reflects a joint vision for long-term prosperity and employment opportunities in both nations,” said the statement.

Trump had arrived in the Kingdom earlier on Tuesday on his first overseas trip since his reelection. He was received by Prince Mohammed bin Salman, Crown Prince and Prime Minister.

The leaders later chaired the Saudi-American summit that reviewed several joint files.

They then signed an economic strategic partnership agreement and oversaw the signing of several agreements between their countries in various fields.
