The Pentagon's Defense Security Cooperation Agency said the sale consisted of $320 million in spare parts and support for F-16 fighters and Active Electronically Scanned Array Radars and related equipment.
The State Department also approved the potential sale to Taiwan of improved mobile subscriber equipment and support for an estimated $65 million, the Pentagon said. The principal contractor for the $65 million sale is General Dynamics.
Taiwan's defense ministry said it expected the sales to "take effect" within a month and that the equipment will help maintain the F-16 fleet's readiness and "build up a credible defense force".
"Taiwan and the United States will continue to strengthen their security partnership and work together to maintain peace and stability in the Taiwan Strait and the Indo-Pacific region," it said in a statement.
Last month, the United States announced a potential $2 billion arms sale package to Taiwan, including the delivery for the first time to the island of an advanced air defense missile system battle-tested in Ukraine.
