US, Saudi Arabia sign $142 billion defence deal during Trump visit
During President Donald Trump’s visit to Saudi Arabia in May 2025, the United States and Saudi Arabia signed a landmark defence agreement valued at nearly $142 billion. This deal is described by the White House as the largest defence cooperation agreement in US history and forms a key part of a broader $600 billion Saudi investment commitment in the United States.
The $142 billion defence package allows Saudi Arabia to purchase advanced American arms, military systems, and services.
The agreement covers contracts with over a dozen US defence companies, focusing on:
Air and missile defence systems
Air force and space advancements
Maritime and coastal security
Border security and land forces modernization
Information and communication systems upgrades
The package also includes extensive training and support to enhance the capacity of the Saudi armed forces, including improvements to military academies and medical services.
While the White House did not specify all equipment or manufacturers, reports indicate that companies such as Lockheed Martin (expected to supply C-130 transport aircraft, missiles, and radars), RTX Corp, Boeing, and Northrop Grumman are among those involved.
The defence deal is part of a much larger $600 billion Saudi commitment to invest in the US, spanning sectors like energy, technology, infrastructure, and critical minerals.
Additional commercial agreements announced alongside the defence package include:
$14.2 billion in exports of gas turbines and energy solutions from General Electric
$4.8 billion in Boeing 737-8 passenger aircraft sales
Saudi Arabia’s Crown Prince Mohammed bin Salman indicated that total investments could eventually reach $1 trillion.
The agreement signals a deepening of US-Saudi commercial and defence cooperation and underscores continued US support for Saudi Arabia’s military modernization.
President Trump emphasized that the US-Saudi relationship is a “bedrock of security and prosperity,” and the deal marks a new era in bilateral ties.
The deal also aims to boost American industries and create high-quality jobs in the US, aligning with the Trump administration’s focus on attracting foreign investment.
The agreement does not clarify whether Saudi Arabia will be allowed to purchase advanced US fighter jets like the F-35, which the kingdom has shown interest in for several years.
The Biden administration previously attempted, without success, to finalize a similar defence agreement with Saudi Arabia as part of a broader Middle East framework.
