Saudi Arabia's state arms producer signed an agreement Sunday with US contractor Lockheed Martin to form a joint venture, a statement said, as Washington reviews weapons sales to the kingdom.
The deal was announced by Saudi Arabian Military Industries (SAMI), which said it will own 51 percent of the venture, as it seeks to boost the kingdom's military capabilities.
"The joint venture is aimed at developing localization capabilities through the transfer of technology and knowledge and training of Saudi nationals to manufacture products and provide services to the kingdom's armed forces," SAMI said in a statement.
Saudi Arabia has long been a major global arms importer.
But some Western countries now refuse to sell weapons to the kingdom over its role in the conflict in neighboring Yemen, gripped by what the United Nations calls the world's worst humanitarian crisis.
Earlier this month, US President Joe Biden's administration announced it was ending support for Saudi Arabia's offensive operations in Yemen's devastating war.
Biden's administration also said it was reviewing weapons sales to the kingdom.
But Lockheed Martin's vice president Timothy Cahill said Sunday's deal marked a "major milestone" for the US company.
"This agreement is in line with Lockheed Martin's strategy to expand its partnership with the kingdom by providing reliable defense and security solutions," Cahill was quoted as saying in the statement.
In 2017, Saudi Arabia's Public Investment Fund set up SAMI to manufacture arms locally, with the fund expecting it to become one of the world's top defense companies by 2030.
Lockheed Martin is among the contractors involved in a project to install a $15 billion Terminal High Altitude Area Defense (THAAD) missile defense system in Saudi Arabia, which was part of a major arms deal approved by former US president Donald Trump in 2017.
Saudi Arabia seeks to boost its defense capabilities as it confronts missile or drone attacks from Yemen's Iran-backed Huthi rebels since it launched a military intervention against them in 2015.
