Under this contract, Xandar LLC will provide NASIC with support for research, development, and sustainment of new and existing hardware, systems and software capabilities enabling scientific and technical intelligence production for the United States Air Force, the Department of Defense and national level intelligence efforts through 2033.

KBR serves as the mentor in the joint venture, which is designed to enhance the capabilities of protégé firms.

“Xandar’s broad technical capabilities and strong understanding of the customer’s mission make us the right partner to support NASIC in meeting both the known and unforeseen challenges of the future,” said KBR Government Solutions U.S. President Byron Bright. “We bring the highly skilled, analytically agile workforce NASIC needs to achieve its vision for the next decade and to lay the technology foundation necessary to solve global security challenges deep into the 21st century.”

Xandar will provide agile and innovative resource capabilities supporting technical analysis in the intelligence community, turning innovation into intelligence products, and constantly improving productivity in technical analysis product generation.

“Xandar is the natural alignment of NASK and KBR with a demonstrated, seamless ability to work together to advance the NASIC mission. NASIC’s need to counter rapidly evolving threats requires the agility of a small company plus the power and scope of a large company,” said NASK President Peter Zurbach. “Xandar is perfectly constructed to meet NASIC’s requirements moving forward.”

The Xandar team will support NASIC’s mission to discover and characterize air, space, missile, forces and cyber threats to enable full-spectrum, multi-domain operations; drive weapon system acquisition; and inform national defense policy.
