Parsons Corporation has secured a task order with a ceiling value of $28 million for Battlespace Command and Control Center integration under the Air-Base Air-Defense contract it was awarded in 2021. The task order, which has a base year and two option periods, involves the procurement, integration and testing of a multi-source correlator tracker software system; the provision of training for that system; and the integration of battlespace awareness and air defense capabilities, Parsons said Thursday.
