The Biden administration plans to formally ask Congress to approve an estimated $1.1 billion arms sale to Taiwan that includes 60 anti-ship missiles and 100 air-to-air missiles, three sources with direct knowledge of the package told Politico on Monday.

The package, which is still in an early stage, includes 60 AGM-84L Harpoon Block II missiles for $355 million, 100 AIM-9X Block II Sidewinder tactical air-to-air missiles for $85.6 million, and $655.4 million for a surveillance radar contract extension, the people said. The Sidewinder missiles will arm Taipei’s US-made F-16 fighter jets.
