The Missile Defense Agency (MDA) awarded a multiple award Indefinite Delivery/Indefinite Quantity (IDIQ) contract to Sphinx LLC valued at $151 billion with a performance period through December 28, 2035. This contract, known as the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program, was awarded on December 29, 2025, with no set-aside designation, allowing full and open competition among qualified contractors. The contract vehicle is designed to procure an advanced, multi-domain defense system capable of detecting, tracking, intercepting, and neutralizing air, missile, space, cyber, and hybrid threats against the United States homeland, deployed forces, allies, and partners across all phases of flight from ballistic, hypersonic, and cruise missiles. Sphinx LLC, a Fredericksburg, Virginia-based limited liability company with demonstrated experience in technology procurement and facilities support services within the defense sector, will serve as one of multiple awardees under this IDIQ structure.

The contracted scope of work encompasses research and development, prototyping, disruptive technologies, systems engineering, weapon design, production, test and evaluation, cybersecurity modernization, and advanced technology integration including artificial intelligence, machine learning, digital engineering, and open systems architectures. Task orders will be issued across multiple NAICS codes and contract types, with performance occurring at various locations including Huntsville, Alabama, and supporting both classified and unclassified programs across multiple security domains. The initial delivery order issued under this IDIQ on December 29, 2025, valued at $500 (firm fixed price), represents the SHIELD initial order component. This comprehensive contracting vehicle is structured to enable the MDA and other Department of Defense entities to rapidly issue orders supporting the nation's multi-layered defense requirements over the 10-year performance period.
