Julia Semantics LLC

Julia Semantics LLC, a small business based in Norfolk, Virginia, has secured two significant multiple-award IDIQs with the Department of Defense — the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program through the Missile Defense Agency and the Seaport Next Generation (Seaport-NXG) vehicle through Naval Sea Systems Command — positioning the vendor as a prime contractor for advanced defense R&D and systems engineering work, with initial task orders valued at $500 each but underlying ceiling values totaling approximately $4 billion.

The vendor operates exclusively as a prime contractor (100% of recent awards) and competes in full-and-open competitions without set-aside reservations on both IDIQs, though it holds SBIR Phase I and Phase II precedent from DARPA as a total small business awardee. Julia Semantics' concrete capability portfolio centers on advanced multi-domain defense system research and development, systems engineering, prototyping, and weapons design for ballistic missile defense and naval operations. Representative work includes a $1.5 million DARPA SBIR Phase II definitive contract awarded July 2022 for research services performed in Norfolk through August 2024, a $225 thousand SBIR Phase I purchase order from DARPA issued July 2021 through May 2022, and minimum-guarantee task orders under both SHIELD and Seaport-NXG that structure future competition for Navy and Missile Defense Agency task orders.

Customer concentration is entirely Department of Defense. Naval Sea Systems Command dominates by potential value — the Seaport-NXG IDIQ carries a $4 billion ceiling — while the Missile Defense Agency and DARPA provide smaller but strategically significant precedent. All six awards in the source sample are prime awards; the vendor has no subcontractor footprint in the disclosed data. Activity is sparse in historical terms — one award per year in 2021 and 2022, then a gap of three years before four awards in 2025 — but the recent cluster reflects momentum into two major vehicle positions. The Seaport-NXG vehicle runs through January 1, 2029, and the SHIELD vehicle extends through December 28, 2035, with both carrying multiple-award competition structures that leave task-order scope and frequency undetermined. Combined dollars obligated to date total $1.7 million against a $4 billion combined potential value, indicating these are newly awarded IDIQs with limited invoiced activity and substantial pipeline runway.
