The US Navy has awarded a $154.1m contract to Northrop Grumman to upgrade Taiwan Air Force (TAF) aircraft, under the Foreign Military Sales Programme.

Under the contract, the company will upgrade six TAF E-2C aircraft from Group II configuration to an advanced version E-2C Hawkeye 2000 (H2K) export configuration.

The E-2C Hawkeye is an airborne surveillance platform which will provide all-weather airborne early warning as well as command and control functions to the navy and marine corps.

The upgraded H2K enhances the E2’s capabilities by installing a Mission Computer Upgrade to improve target detection and tracking, Cooprative Engagement Capability and an advanced Electronic Support Measures system.

The Hawkeye will extend the engagement capability of surface forces and also the lethal range of standard missiles.

Work will be carried out in New York, Florida and various other locations in the US and is expected to be complete by June 2013.

The Navy’s Naval Air Systems Command, Patuxent River, Maryland, has awarded the contract.
