Singapore plans to upgrade a fleet of US-made fighter jets with an initial purchase of four more advanced F-35 models to replace F-16s.
The defense minister of the city-state, Ng Eng Hen, told parliament Friday that the price has not been determined.
A request to buy the Lockheed Martin jets would be subject to U.S. congressional approval.
Ng said that the price of the F-35 supersonic plane has been steadily falling and currently ranges from $90 million to $115 million.
Singapore’s military is planning to fully replace its current fleet of F-16 American-made fighter jets within a decade.
