The US is set to sell $100m worth of necessary equipment and services to help Taiwan to maintain and improve its Patriot Air Defense System.

This comes after the US State Department approved the possible foreign military sale (FMS) to the Taipei Economic and Cultural Representative Office (TECRO), in the United States.

The Defense Security Cooperation Agency (DSCA) has delivered the required certification informing US Congress of the possible sale.

The TECRO placed a request to purchase equipment and services to support its participation in the patriot international engineering services program (IESP), and field surveillance program (FSP) for five years, along with the necessary engineering services.

It included missile field surveillance support for legacy guidance enhanced missiles (GEM), and Patriot Advanced Capability-3 (PAC-3) missiles, among other related support.

The prime contractors for the potential sale will be Raytheon Technologies and Lockheed Martin.

According to the DSCA, the procurement will help Taiwan to maintain its missile density and readiness for air operations. It will use the capability to deter regional threats and improve its defences.

“This proposed sale serves US national, economic, and security interests by supporting the recipient’s continuing efforts to modernise its armed forces and to maintain a credible defensive capability.

“The proposed sale will help improve the security of the recipient and assist in maintaining political stability, military balance, and progress in the region,” the DSCA statement added.

In August last year, the US State Department approved a $750m possible foreign military sale (FMS) of 155mm M109A6 Paladin medium self-propelled howitzer (SPH) systems to TECRO.
