Lockheed Martin has begun early delivery of the first target sight system (TSS) follow-on production units for the US Marine Corps AH-1Z Cobra attack helicopter.

The TSS unit is the multisensor fire control system for the Cobra helicopter to provide pilots with enhanced capabilities to detect, track and engage targets in every climate and location.

The upgraded integrated sensor units feature a laser designator, colour video display and a third-generation, mid-wave, forward-looking infrared sensor with advanced image processing to provide additional targeting capabilities.

Additional targeting capabilities include a new target-sizing function, refined geolocation accuracy and superior weapon alignment.

The follow-on production contract was awarded by the US Naval Surface Warfare Center in June 2010.

Production will take place at the company’s facilities in Florida, US, through to 2018.
