Korea may receive US support for upgrading its 35 F-16 Block 32 aircrafts, according to the US Defense Security Cooperation Agency.

The support material will enable the country to optimise the capability of the F-16s in both deterrent and coalition roles with United States Forces Korea and the Combined Forces Command.

The $250m upgrade will allow Korea to deploy joint direct attack munitions, advanced medium range air-to-air missiles, improved data modem and secure voice capabilities.

The US Government will also provide test and support equipment, spare and repair parts, personnel training and training equipment, publications, technical data and assistance, and logistics support.

Lockheed Martin is expected to be the primary contractor for the sale.
