The contract, designated as Scalable Homeland Innovative Enterprise Layered Defense (SHIELD), represents a comprehensive, multi-domain defense procurement vehicle designed to provide advanced capabilities for detecting, tracking, intercepting, and neutralizing threats to United States homeland, deployed forces, allies, and friends. The scope of work encompasses research and development, prototyping, disruptive technologies, systems engineering, weapon design, production, test and evaluation, cybersecurity modernization, and protection against air, missile, space, cyber, and hybrid threats across all phases of flight from ballistic, hypersonic, and cruise missiles. No set-aside designations were applied to this full and open competition contract, which is structured to award to all qualifying offerors determined to be responsible sources with technically acceptable proposals demonstrating fair and reasonable pricing.

The initial task order issued under the SHIELD IDIQ contract is valued at five hundred dollars with a firm fixed-price pricing structure and a completion date of December 28, 2035. This initial delivery order, awarded simultaneously with the IDV on December 29, 2025, is designated as the SHIELD Initial Order and is performed at the Missile Defense Agency's location in Huntsville, Alabama. The contract vehicle is structured to support both classified and unclassified programs across multiple security domains and leverage advanced technologies including artificial intelligence, machine learning, digital engineering, and open systems architectures. Individual task and delivery orders under the IDIQ will utilize various contract types across multiple North American Industry Classification System codes, with resultant work potentially issued at different classification levels requiring appropriate facility clearances, enabling the Missile Defense Agency and other Department of Defense entities to rapidly issue orders under this flexible contracting mechanism to address evolving homeland defense requirements.
