The contract deliverables focus on advanced defense systems capable of detecting, tracking, intercepting, and neutralizing threats to the United States homeland, deployed forces, allies, and friends across air, missile, space, cyber, and hybrid threat domains throughout all phases of flight, including ballistic, hypersonic, and cruise missile threats. Work under the contract leverages advanced technologies including artificial intelligence, machine learning, digital engineering, and open systems architectures. As the prime contractor, SSAI is responsible for providing all necessary materials, labor, equipment, and facilities incidental to task order performance, with individual delivery orders to be issued on an as-needed basis across multiple Department of Defense entities under the flexible IDIQ mechanism.
