Press Release

HOUSTON – (Feb. 16, 2021) – KBR (NYSE: KBR) won a $92.6 million contract to perform engineering, integration and sustainment services on counter unmanned air systems (C-UAS) for the Combat Integration & Identification Systems unit within the U.S. Naval Air Warfare Center Aircraft Division (NAWCAD). This cost-plus-fixed-fee, indefinite-delivery/indefinite-quantity (IDIQ) contract is a new opportunity for KBR to help the U.S. military with ground-based air defense.

KBR will provide its expertise to various Navy identification and data link systems, which include the Negation of Improvised Non-State Joint Aerial-Threats (NINJA) system; Counter-Remote Control Model Aircraft Integrated Air Defense Network (CORIAN) system; SkyTracker® UAS detection and tracking suite; Light Marine Air Defense Integrated System (LMADIS); Marine Air Defense Integrated System (MADIS); and ANDURIL artificial intelligence platforms.

The Department of Defense (DoD) uses these C-UAS to strengthen homeland security and address potential threats in the U.S. and abroad. The systems can scan the skies for enemy aircraft and take appropriate action to deny airspace access.

KBR’s specific tasks will include the integration and installation of systems; the characterization of system and sub-system components; development of training curriculum and materials, as well as delivery of formal training programs; supply system management and material control; testing and repair of C-UAS; and laboratory maintenance and quality assurance. The company will perform the five-year contract primarily at Webster Outlying Field in St. Inigoes, Maryland.

KBR’s services supporting NAWCAD will also benefit programs sponsored by the Naval Air Systems Command; Naval Sea Systems Command; Naval Inventory Control Point – Mechanicsburg; U.S. Coast Guard; commercial and Foreign Military Sales customers; and other DoD and government entities.

“Our work through this new win will have wide-reaching impacts within the DoD and international allied community,” said Byron Bright, KBR Government Solutions President. “We are excited to join NAWCAD as it advances C-UAS technology and, ultimately, strengthens national security and protects our armed forces around the globe.”
