Raytheon has completed the upgrade and delivery of the first of six configuration-3 Patriot radar systems for Kuwait under a $148m foreign military sales contract with the US Army Aviation and Missile Command (AMCOM).

Raytheon Integrated Defense Systems (IDS) Integrated Air and Missile Defence vice-president Sanjay Kapoor said the upgrade will enhance the nation’s ability to protect itself against tactical ballistic missile attacks.

Kapoor added that the deal highlighted Kuwait’s efforts to maintain the integrated air and missile defence system’s readiness to counter increasing and emerging regional threats.

The Patriot is a long-range, all-altitude, all-weather defence system designed to provide protection against advanced threats including aircraft, tactical ballistic missiles, cruise missiles and unmanned aerial vehicles (UAVs).

The missile is equipped with a track-via-missile (TVM) guidance system that helps transmit target data via the ground radar to the engagement control station for final course correction calculations.

The target engagement can be carried out in manual, semi-automatic or automatic mode. After launch, the missile is acquired by a trailer-mounted AN/MPQ-53 phased array radar that carries out search, detection and missile-tracking functions.

The Patriot is in service with 12 nations worldwide including the US, Egypt, Germany, Greece, Israel, Japan, Kuwait, the Netherlands and Saudi Arabia.

Work under the contract is being carried out at the IDS facility in Massachusetts, US, and the company did not reveal timelines for completion of the remaining five radar upgrades.

Raytheon IDS is the prime contractor for both domestic and international Patriot air and missile defence systems and the system integrator for Patriot advanced capability-3 missiles.
