About Citadel Defense
Citadel Defense specializes in developing advanced counter unmanned aircraft systems (CUAS) designed to detect, identify, and neutralize drone threats before they pose a danger. The company's flagship product, Titan CUAS, is widely deployed to safeguard troops, vehicles, and critical infrastructure from drone attacks and swarms. Citadel's technology is particularly valued by the U.S. Navy for its performance, ease of use, and flexibility in various mission scenarios. Operating primarily in the defense and security market, Citadel serves military organizations, government agencies, and operators of high-value assets such as airports, ports, and large venues. The business model revolves around selling and maintaining CUAS technology, leveraging artificial intelligence and machine learning to stay ahead of evolving drone tactics. Revenue is generated through direct sales, service contracts, and ongoing support agreements.
