National Security


Arnold & Porter LLP's National Security practice is one of the largest and most experienced in Washington. It is anchored by numerous former senior US government officials who have decades of experience in national security legal positions, including the former General Counsels of the Central Intelligence Agency, Jeffrey Smith; the National Security Agency, Ronald D. Lee; the Army and the Air Force, Charles Blanchard; and the former Legal Adviser to the Department of State and the Legal Adviser to the National Security Council at the White House, John Bellinger.

Our practice also includes former senior national security officials at the Departments of Justice, State, Treasury, and Homeland Security, and the former ranking member of the House Select Committee on Homeland Security, Jim Turner.

Our national security lawyers understand the legal and policy framework in which particular issues arise, and the US government processes in which sensitive national security decisions are made. Our lawyers speak and write regularly about national security matters and maintain close contacts with relevant US government agencies. Many of our lawyers hold security clearances and are able to advise clients on classified matters.

Our clients benefit from a fully integrated practice that works hand-in-hand with colleagues in the related areas of government contracts, intellectual property, corporate and securities, pharmaceuticals and medical devices, information security and privacy, litigation, and criminal investigations. Our comprehensive approach allows us to bring together teams from across our firm to address our clients' most pressing and complex legal needs with insight and creativity.

Our national security team counsels US and international government contractors in structuring and negotiating teaming arrangements, technology transfers, co-production agreements, and equity joint ventures in the US and abroad. Over the past decade, our attorneys have counseled on more than 100 cooperative research and development arrangements—as well as production and marketing deals—in such fields as tactical communications, electronic warfare systems, aircraft production, torpedo manufacture, missile system development and manufacture, alternative energy sources, automotive components and vehicles, tank subassemblies, and computer systems.

In addition to advising government contractors on the full range of US laws and regulations applicable to such transactions (Exon-Florio, the ITAR, EAR, and FOCI rules, etc.), our lawyers also advise and represent international governments regarding purchases made from US defense contractors, including those made with foreign military sales funds. We also have substantial experience in dealing with issues arising under classified or so-called "black" programs.
