Antean Technology LLC, a minority-owned, women-owned small business headquartered in Alexandria, Virginia, has been awarded a multiple-award Indefinite Delivery Indefinite Quantity (IDIQ) contract by the Missile Defense Agency under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program. This indefinite delivery contract, awarded on December 29, 2025, carries a ceiling value of $151 billion with an ultimate completion date of December 28, 2035. The contract represents a full and open competition vehicle with no set-aside restrictions, enabling the Missile Defense Agency and other Department of Defense entities to issue task orders for advanced, multi-domain defense system capabilities. As a multiple-award IDIQ, this vehicle allows the government to competitively award orders among qualifying contractors meeting responsibility and technical acceptability standards with fair and reasonable pricing.

The SHIELD IDIQ contract procures research and development, prototyping, systems engineering, weapon design, production, test and evaluation, cybersecurity, and modernization services supporting a comprehensive, layered defense architecture capable of detecting, tracking, intercepting, and neutralizing air, missile, space, cyber, and hybrid threats across all phases of flight. Work encompasses ballistic missile defense, hypersonic threat countermeasures, cruise missile defense, and advanced aerial attack prevention for homeland defense and force protection. The contract vehicle is structured to support both classified and unclassified programs across multiple security domains, leveraging disruptive technologies including artificial intelligence, machine learning, digital engineering, and open systems architectures. Individual task and delivery orders will utilize various contract types across multiple North American Industry Classification System codes and may require appropriate facility clearances for work performed at different classification levels, positioning the SHIELD IDIQ as a strategic long-term investment in integrated national defense capabilities.
