The government of Singapore has detailed the upgrade of its fleet of F-16 fighters, which first entered service with its military in 1998.

The modernization of Republic of Singapore Air Force FG-16s begins in 2016 and will be conducted in phases over a period of five to six years.

The aircraft are to receive active electronically scanned array radar, extending the F-16's detection range and enabling the fighter to track and engage multiple targets at greater distances. It will also give the F-16 an all-weather, ground-attack capability and the capability to use more capable precision munitions, such as the Laser Joint Direct Attack Munition.

The government said a datalink capability and the use of an advanced helmet-mounted display will allow superior situational awareness.

"The upgrade program enhances the capabilities of the RSAF's fighter fleet and ensures that Singapore's defense and security needs are met," the government said.

Singapore had requested the modernization from the United States, which approved it under the U.S. Foreign Military Sales program.
