Naval Air Station Patuxent River is a U.S. Navy air station in St. Mary's County supporting research, development, test, and evaluation across the Naval Aviation Enterprise. Its Air Operations Department manages two Navy airfields—the main station and Webster Outlying Field—and handles about 165,000 annual air operations, including flight-test, search-and-rescue, flight-support, airfield-facilities and ground-electronics functions. This is an active military installation with controlled access, not a walk-in aviation attraction: visitors should review current base-access guidance and keep identification ready for gate scanning. The Gate 2 Pass Office at (301) 342-3231 provides visitor vehicle passes on weekdays excluding holidays; the Navy warns that advance arrangements and delays of up to two hours may apply. Public transportation from regional airports is very limited. Visitor address: 22268 Cedar Point Road, Building 409, Patuxent River, Maryland 20670, United States; base operator (301) 342-3000. Confirm access and operating conditions before travel.
