Indefinite Delivery Contract HQ085926DE035

Systems Engineering Support Co. (Sesco), a San Diego-based minority-owned and veteran-owned small business, was awarded a multiple-award Indefinite Delivery Contract valued at $151 billion by the Missile Defense Agency on December 29, 2025, with an ultimate completion date of December 28, 2035. This contract serves as the primary vehicle for the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program, which procures advanced, multi-domain defense systems capable of detecting, tracking, intercepting, and neutralizing air, missile, space, cyber, and hybrid threats across all phases of flight. The contract encompasses a broad scope including research and development, prototyping, disruptive technologies, systems engineering, weapon design, production, test and evaluation, cybersecurity, and modernization efforts. The award utilizes full and open competition with no set-aside designation, allowing multiple qualified contractors to compete for delivery orders under the indefinite quantity framework. The contract structure supports both classified and unclassified programs across multiple security domains and leverages advanced technologies including artificial intelligence, machine learning, digital engineering, and open systems architectures.

Under this SHIELD IDIQ contract, the prime contractor shall provide all necessary materials, labor, equipment, and facilities required to perform delivery orders issued by the Missile Defense Agency and potentially other Department of Defense entities. Individual task and delivery orders will utilize various contract types and pricing mechanisms across multiple North American Industry Classification System codes, with orders potentially issued at different classification levels requiring appropriate facility clearances. A representative delivery order issued on December 29, 2025, with a firm fixed price structure and place of performance in Huntsville, Alabama, demonstrates the contract's operational initiation. The 10-year period of performance, consisting of a base ordering period and optional ordering periods, positions the SHIELD IDIQ as a comprehensive, long-term contracting vehicle designed to enable rapid issuance of orders supporting the nation's multi-layered homeland defense requirements across all service branches and defense agencies.
