The Defense Security Cooperation Agency, in a notification this week to Congress, said Thailand is seeking nine missiles, which are used for ship-borne anti-missile and anti-aircraft defense.
"This proposed sale will contribute to the foreign policy and national security of the United States by increasing the ability of Thailand to contribute to regional security and improving interoperability with the U.S. Military in operational and exercise scenarios," the agency said.
"It is consistent with U.S. national interests to assist Thailand in developing and maintaining a strong and ready ship self-defense capability, which will contribute to the military balance in the area."
In addition to the nine missiles, Thailand is seeking three MK25 Quad Pack canisters; four MK783 shipping containers; spare and repair parts; support and test equipment; publications and technical documentation; personnel training and training equipment.
The prime contractors would be Raytheon Missile Systems and BAE Systems.
The value of the package is $18 million.
