Jack Northrop Field Hawthorne Municipal Airport — Hawthorne, United States

Jack Northrop Field, also known as Hawthorne Municipal Airport and coded HHR, is located in Hawthorne, California, in the greater Los Angeles area, and carries deep aerospace heritage tied to its namesake Jack Northrop, founder of Northrop Corporation. The airport is best known today for hosting SpaceX's headquarters and manufacturing facility adjacent to the runway, making it a notable site in the modern commercial space industry despite functioning primarily as a general aviation field. HHR does not offer scheduled passenger airline service, instead handling private aircraft, corporate flights, and flight training operations. Its location amid dense Los Angeles suburbs makes noise abatement and community relations an ongoing consideration for airport operations.
