The Pentagon has notified Congress of the sale approved on October 26 on Thursday which will provide Saudi Arabia with 280 air-to-air missiles.
The missiles purchased by Saudi Arabia are capable of flying 20 miles and hitting an aerial target beyond a pilot's visual range.
The package also includes 596 LAU-128 Missile Rail Launchers (MRL) along with containers and support equipment, spare parts.
Other Arab states including Qatar, Kuwait and Jordan have previously bought the missiles.
The US-Saudi arms deal has been announced amid much criticism on Riyadh over its military aggression against Yemen.
