The US Department of State said on Thursday it had approved the potential sale of Lockheed Martin’s F-35 Lightning II fighter jets to Saudi Arabia, as the kingdom is drawn deeper into ‌war in the Middle East.

A sale would mark a significant policy shift from the US, potentially altering the balance ‌of military power in the Middle East and testing Washington’s definition of maintaining its ally Israel’s “qualitative military edge.”

Saudi Arabia made a direct appeal for the jets ​in early 2025 to US President Donald Trump and has long been interested in Lockheed Martin’s fighter.The estimated $24.3 billion sale, which still needs congressional approval, would include 48 of the military aircraft and 49 Pratt & Whitney engines along with communications equipment, spare parts and other support items, the State Department said.

Washington weighs weapons sales to the Middle East in a way that ensures Israel maintains a “qualitative military ‌edge”, effectively guaranteeing that Israel gets more advanced ⁠US weapons than regional Arab states.

The Saudi embassy in Washington welcomed the proposed sale, describing it as a further step in defense cooperation between the two countries.

“The proposed F-35 sale reflects the strength and ⁠enduring nature of the Saudi-U.S. strategic partnership and the continued advancement of our defense cooperation,” the embassy said on X.

The F-35, built with stealth technology that allows it to evade enemy detection, is considered the world’s most advanced fighter jet. Israel has operated the aircraft for ​a decade, ​building multiple squadrons, and remains the only Middle Eastern country to ​possess the system.

Saudi Arabia, the largest customer for US ‌arms, has sought the fighter for years as it looks to modernize its air force and counter regional threats, particularly from Iran. The kingdom’s renewed push for what would constitute two squadrons comes as the Trump administration has signaled openness to deepening defense cooperation with Riyadh. The Saudi Air Force flies a mix of fighter aircraft including Boeing F-15s, European Tornados and Typhoons.

The F-35 issue has also been intertwined with broader diplomatic efforts. The administration of former US President Joe Biden previously explored providing F-35s ‌to Saudi Arabia as part of a comprehensive deal that would have ​included Riyadh normalizing relations with Israel, though those efforts ultimately stalled.

Trump has ​made arms sales to Saudi Arabia a priority since ​returning to office. In 2025, the United States agreed to sell the kingdom an arms package worth ‌nearly $142 billion, which the White House called “the largest ​defense cooperation agreement” Washington has ever ​done.

Congressional scrutiny could pose challenges to any F-35 sale. Lawmakers previously questioned arms deals with Riyadh following the 2018 murder of Saudi journalist Jamal Khashoggi, and some members of Congress remain wary of deepening military cooperation with the kingdom.

Saudi ​Arabia is pursuing ambitious economic and military ‌modernization plans under Crown Prince Mohammed bin Salman’s Vision 2030 agenda. It has sought to diversify its defense ​partnerships while maintaining its decades-long security relationship with Washington.
