Office of Law Enofrcement, Federal Air Marshal Service


The mission of the Transportation Security Administration (TSA) Office of Law Enforcement/Federal Air Marshal Service (OLE/FAMS) is to promote public confidence in the security of our Nation's transportation domain.

To achieve this mission, OLE/FAMS deploys Federal Air Marshals on U.S. aircraft world-wide; conducts protection, response, detection, and assessment activities in airports and other transportation systems; maintains TSA's state of preparedness and coordinates incident management; trains and manages all armed pilots; and trains all TSA canine assets.

Federal Air Marshals serve as the primary law enforcement entity within TSA. We deploy on flights around the world and in the United States. While our primary mission of protecting air passengers and crew has not changed much over the years, Federal Air Marshals have an ever expanding role in homeland security and work closely with other law enforcement agencies to accomplish their mission. The men and women who make up the Federal Air Marshal Service are dedicated, well trained law enforcement professionals, each equipped with the knowledge, skills, and abilities necessary to keep our aviation system safe and secure.
