Kuwait is interested in buying a package of military hardware including a Globemaster III aircraft from the United States.
According to a statement from the US Defence Security Cooperation Agency, the Kuwaiti government is keen to buy the equipment in a deal worth $371m.
The Agency said it has notified Congress of the possible foreign military sale to Kuwait for one C-17 Globemaster III aircraft and associated equipment, parts, training and logistical support.
As well as the giant airlifter aircraft, the package would include four Turbofan F117-PW-100 Engines, a missile approach warning system, secure radios, precision navigation equipment and spare and repair parts, the Agency said.
It added that the provision of a second C-17 would provide the Kuwait Air Force with "a more robust regional airlift and long-range strategic airlift capability".
The additional C-17 aircraft will allow the country's air force to better participate in humanitarian support operations, it said.
"Kuwait continues to be a key ally and strong supporter of US foreign policy and national security goals in the Persian Gulf region," the statement said.
"The proposed sale will enhance the United States foreign policy and national security objectives by increasing interoperability among the Kuwait Air Force, the United States Air Force, Gulf Cooperation Council countries, and other coalition forces."
The prime contractor will be The Boeing Company, it added.
