Lockheed has been awarded a contract modification to the engineering, manufacturing, and development contract for the US Air Force (USAF) space-based infrared system (SBIRS).

The $460.3m contract is to deliver the next block of ground systems capability, block 10, which allows the four different mission areas to be divided to achieve future sustainment efficiencies.

The block 10 system will perform integrated processing of data from the SBIRS ensuring that the data is available to a large community of users for both real time activities as well off-line analysis.

The upgraded ground system will be fielded at one primary and one back-up government facility, and will replace the existing operational ground system, DSP overhead persistent infrared satellites.

The system will provide missile warning and battle space awareness messages to warfighters, and other relevant data to technical intelligence and missile defence users.

Work will be performed at the company’s facility in California, US, with the US Space and Missile Systems Centre, Los Angeles Air Force Base being the contracting activity.
