NAS Patuxent River Navy Base in Lexington Park, MD Maryland Military Bases


Naval Air Station (NAS) Patuxent River is one of the military bases established under the command of the United States Navy. It is often referred to as NAS Pax River. It is located in the southern part of Maryland, in Saint Mary’s County. The name of the base comes after the nearby river Patuxent River, whose mouth is in the immediate proximity. It is one of the most important bases run by the US Navy due to the Test Pilot School on site. The base also starred in one of Harrison Ford’s movies. “Random Hearts”, which was released in 1999, presented Harrison Ford flying a plane himself, as he is a certified pilot.


The history of NAS Patuxent River begins on the Fool’s Day. It was established on April, 1-st, 1943. Although World War Ii was already at its peak, the base quickly grew to become one of the main players. Prior to the construction, the land belonged to local farmers. The place was not entirely erased. Some of the old homes were actually kept to serve the US Navy necessities. The construction was approved a few weeks after the Pearl Harbor attacks, but was delayed until the summer of 1942. The place helped Saint Mary’s County improve a little and increase its value. Since the transportation was not that advanced in the area, the authorities worked on a few railroads and some new streets. The construction was fast. There were more than 7,000 workers struggling to finish it as soon as possible. It came as a great employer in the area. People from Saint Mary’s County and the nearby counties rushed to get a job at the high paying installation. At the time the construction was over, the new station was referred to as the most significant military base of the US Navy.


The US Marines arrived on site before the base was done. They came in a few months after the construction actually began. They joined for security measures. These days, the security is operated by the MA (Masters at Arms), the Department of Defense, the NCIS (Naval Criminal Investigation Service) and a few contractors. During its first weeks, the base was named Cedar Point, but the authorities were concerned about the potential confusion with a different base from North Carolina, so the name was later changed.


Exactly 33 years after the groundbreaking ceremony, the airfield on site was renamed in the memory of Frederick M. Trapnell, one of the local commanders.



NAS Patuxent River is also popular for the local museum, which presents the living history of the US Navy technology and aviation. Other than that, it is an open book to the local history of the base. The museum doesn’t host just old aircrafts and artifacts, but also documents, photos, testimonials and movies.



There are six major tenant units hosted at NAS Patuxent River. The Air System Command, the Test Pilot School and the Scientific Development Squadron 1 are the most important ones. There are also a few less significant and temporary units deployed there.

NAS Patuxent River




Naval Air Station Patuxent River stretches across approximately 12 miles of shoreline at the mouth of the Patuxent River in St. Mary’s county, overlooking the picturesque Chesapeake Bay, 65 miles southeast of Washington, D.C. and 75 miles south of Baltimore. NAS Patuxent River covers more than 13,800 acres, including the Bloodsworth Island Range and the Webster Field Annex, which is located about 15 miles south of the station. Patuxent River is located outside of Lexington Park in southern Maryland.



Situated on a peninsula between the Patuxent River and the Chesapeake Bay, NAS Patuxent River is located on 6,400 acres (26 km²) of what was once prime farmland, consisting of several large farms, Mattapany, Susquehanna, and Cedar Point, as well as numerous tenant and sharecropper properties and a few clusters of vacation homes. The Cedar Point community included several churches, a post office, and a gas station. Some of the old homes now serve as quarters for Navy personnel stationed there. In 1937, the Navy’s Bureau of Aeronautics sought to consolidate aviation test programs, previously being conducted at several stations, including Dahlgren and Norfolk, Virginia, the Washington Navy Yard, and Naval Air Station Anacostia in Washington, D.C., and the Naval Aircraft Factory in Philadelphia, Pennsylvania. Cedar Point was selected due to its remote location on the coastline, well removed from air traffic congestion, with ample space for weapons testing.



Patuxent River is home to the Naval Air Systems Command and the Naval Air Warfare Center Aircraft Division headquarters. NAVAIR’s Aircraft Division at Patuxent River (including the Webster Field Annex) is the Navy’s full spectrum acquisition, research, development, test, evaluation and engineering and fleet support activity for manned and unmanned aircraft, engines, avionics, aircraft support systems and ship/shore/air operations. With more than 165,000 air operations annually, activities at Patuxent River fly 140 different aircraft over 780 restricted and 5,000 controlled square miles. Capabilities range from concepts analysis and procurement to flight testing and support equipment. NAS Patuxent River is under the command of Naval District Washington (NDW). NDW is one of ten regions reporting to Commander, Navy Installations. Headquartered at the Washington Navy Yard, NDW is the regional provider of common operating support to twenty Navy installations, including Naval Air Station Patuxent River. NDW is also known as the Quarterdeck of the Navy.
