Our global, cross-disciplinary team advises clients across the defence sector. We support land, maritime, aerospace, space and cyber defence activities.

For decades, Clifford Chance has supported national and multinational defence companies on high-stakes business decisions, regulatory investigations and complex disputes.
Our global team includes people with military backgrounds and deep sector insight. This gives us a clear understanding of the legal, strategic and operational challenges clients face in the defence industry.

Our team offers deep expertise in defence export compliance under key legal frameworks, including the International Traffic in Arms Regulations (ITAR), the Foreign Corrupt Practices Act (FCPA), and the Export Administration Regulations (EAR). We also regularly advise on CFIUS reviews, the Defense Counterintelligence and Security Agency (DCSA) process, Foreign Ownership, Control, or Influence (FOCI) mitigation strategies, and legal considerations surrounding the acquisition of private assets by foreign entities. Our insight and experience are critical to managing regulatory risk while enabling strategic growth.
