The sale of six AN/TPQ-53 (V) systems, under the U.S. Foreign Military Sales program, carries a price tag of $179 million.
"This proposed sale will contribute to the foreign policy and national security of the United States by increasing the ability of the Republic of Singapore to contribute to regional security," the U.S. Defense Security Cooperation Agency said in its notification to Congress. "Its contributions to counter-piracy and counter-terrorism efforts continue to stabilize a critical choke point where much of the world's goods and services transit en route to and from the Asia-Pacific region.
"The proposed sale will improve the security of a strategic partner which has been, and continues to be, an important force for political stability and economic progress in the Asia-Pacific region."
In addition to the systems themselves, Singapore is also requesting associated equipment, parts, training and logistical support.
The principal contractor would be Lockheed Martin.
