Oman and Saudi Arabia are purchasing the AIM-120 C7 missiles under the contract, which covers production lot 27, the Defense Department said Friday.
Thirty-six countries have acquired the AIM-120 and the missile has been used during combat in Iraq, Bosnia and Kosovo, according to Raytheon.
Singapore also plans to purchase 100 of the missiles under a separate $210 million foreign military sales agreement announced in April.
Raytheon, ATK (NYSE: ATK), Honeywell (HON) and ITT (NYSE: ITT) are the prime contractors for that sale.
