Engenix, Inc., a women-owned small business headquartered in Huntsville, Alabama, was awarded a multiple-award Indefinite Delivery Contract by the Missile Defense Agency on December 29, 2025, with a ceiling value of $151 billion and a performance period extending through December 28, 2035. The SHIELD (Scalable Homeland Innovative Enterprise Layered Defense) contract is a full and open competition vehicle structured to procure an advanced, multi-domain defense system designed to detect, track, intercept, and neutralize threats to the United States homeland, deployed forces, allies, and friends. The contract encompasses research and development, prototyping, disruptive technologies, systems engineering, weapon design, production, test and evaluation, cybersecurity, and modernization efforts across multiple domains including air, missile, space, cyber, and hybrid threat environments. Work will address threats across all phases of flight from ballistic, hypersonic, and cruise missiles, as well as advanced aerial attacks, utilizing emerging technologies including artificial intelligence, machine learning, digital engineering, and open systems architectures.

The initial delivery order issued to Engenix under the SHIELD contract is valued at five hundred dollars on a firm-fixed-price basis and is titled "SHIELD Initial Order," with performance conducted in Huntsville, Alabama. This nominal initial order represents the baseline task order under the broader multiple-award indefinite delivery vehicle, which is anticipated to issue numerous follow-on delivery and task orders to support the Missile Defense Agency's long-term national defense objectives. The contract was posted as a pre-solicitation notice on May 21, 2025, with a final Request for Proposal released in the fourth quarter of fiscal year 2025, and is structured to support both classified and unclassified programs requiring appropriate facility clearances. No small business set-asides were utilized for this procurement, allowing all qualified contractors to compete for task orders under the flexible contracting mechanism.
