Citadel Defense Company (acquired by BlueHalo)

Citadel Defense Company is a provider of cutting-edge counter-unmanned aerial systems (cUAS) technology. Headquartered in San Diego, California, the company was founded in 2016 by a team of engineers and data scientists. Citadel develops advanced cUAS products that leverage proprietary artificial intelligence (AI) and machine learning (ML) algorithms. These algorithms enable operators to detect drone threats, track their flight paths, and autonomously neutralize the threats.

Citadel's industry-leading cUAS solutions offer a distinct operational advantage, especially when defending against drone swarms and difficult-to-detect threats. The company's AI/ML-powered systems allow operators to identify and terminate enemy unmanned aerial system (UAS) threats with unmatched speed, accuracy, and reliability. In November 2021, Citadel Defense was acquired by BlueHalo, a national security technology provider, to enhance BlueHalo's counter-drone capabilities and deliver unified multi-modal cUAS solutions.

The company was acquired by BlueHalo, a provider of advanced engineering solutions and technology to the national security community, and integrated with the Latter's product portfolio in November 2021.
