President Barack Obama’s administration has proposed to sell air-to-surface guided missiles and related gear to equip Indonesia’s growing fleet of U.S.-built F-16 fighter aircraft.

The sale, valued at $25 million, would be the latest U.S. move to boost security ties with friends and allies in a region stirred by China’s growing military clout and territorial assertiveness.

Indonesia has requested 18 AGM-65K2 “Maverick All-Up-Round” missiles, 36 “captive air training missiles” and three maintenance training missiles, plus spares, test equipment and personnel training, the administration told the U.S. Congress in a notice dated Wednesday.

The AGM-65 Maverick, built by Raytheon Co, is designed to attack a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities.

“The Indonesian Air Force needs these missiles to train its F-16 pilots in basic air-to-ground weapons employment,” the Pentagon’s Defense Security Cooperation Agency said in the notice to lawmakers.

The arms sale would contribute to making Indonesia “a more valuable regional partner in an important area of the world,” the security agency added.

Such notices of a proposed sale are required by law and do not mean the sale has been concluded.
