Northrop Grumman upgrades Hawk EO/IR sensors
Northrop Grumman has announced the release of the latest upgrade for the Hawk Air Defense System’s electro-optical/infrared (EO/IR) sensors, the Fourth Generation Tracking Adjunct Sensor (4G TAS). The company made the announcement on 25 March.
The 4G TAS detects and tracks low, fast targets both day and night and passes them to the Hawk's fire control radar. The gimbaled, stabilised, high-resolution sensor system provides passive EO/IR searching, tracking, launch and pass-off capability for the Hawk air defence system. It can provide threat assessment and identification beyond visual range, providing real-time situational awareness.
According to the company this is the only approved EO/IR upgrade available to Hawk customers worldwide, and all existing TAS, Improved TAS and Advanced Infrared TAS systems can be upgraded to the 4G TAS configuration.
Upgrades to the baseline configuration include a new 640 x 480 pixel infrared sensor that will more than double the resolution of the current system. The upgrade will also include a new charged-coupled device camera that will increase resolution and enhance operation in low-light environments; as well as including more reliable and sustainable electronics to ensure continued logistics support for the system.
Jim Mocarski, vice president of airborne tactical sensors at Northrop Grumman, said: ‘With the launch of 4G TAS, Northrop Grumman brings powerful and sustainable new capabilities to operators of the Hawk system. We continue to invest in sensors for the Hawk and will support our customers worldwide with these upgrades to help them maintain their national security.’
