The Government of Romania has requested the US to provide upgrades and logistics support for its F-16 fighter aircraft fleet.
Support will be carried out through the US foreign military sale route.
Approved by the US State Department, the sale of the modernisation and logistics support is worth an estimated $175.4m.
The US Defense Security Cooperation Agency (DSCA) has notified Congress about the sale.
Under the deal, Romania has sought avionics, software, communication equipment, navigational aids, and cockpit upgrades of the Mid-Life Update (MLU) Block 15 F-16 aircraft fleet.
Eight LN-260 Global Positioning Systems (GPS) and 19 Multifunctional Information Distribution System Joint Tactical Radio Systems (MIDS JTRS) have also been requested for the aircraft modernisation.
It also includes AN/APX-126 advanced identification friend or foe (IFF), ARC-210 radios, KIV-78 cryptographic appliques, other secure communications, navigation, and encryption devices and joint mission planning system (JMPS) software among others.
The modernisation will help Romania comply with Nato interoperability requirements for encrypted communications systems. It will also enhance its capability to defend against existing and emerging threats.
In a statement, DSCA said: “This proposed sale will support the foreign policy goals and national security of the United States by helping to improve the security of a Nato ally in developing and maintaining a strong and ready self-defence capability.
“This proposed sale will enhance US national security objectives in the region.”
Lockheed Martin Aeronautics Company in Fort Worth, Texas, will serve as the principal contractor of the sale.
Last week, the US State Department approved a possible foreign military sale of Bell 412EPi and 429 Helicopters to the Guyanan Government.
