Naval Air Station Patuxent River, also known as NAS Pax River, is a United States Naval airfield located in St. Mary's County, Maryland. It is the home of the Naval Air Systems Command (NAVAIR), the Naval Test Pilot School, the Atlantic Test Range, and numerous other military and civilian organizations. NAS Pax River serves as a center for research, development, testing, and evaluation of Naval aviation systems and aircraft.

The history of NAS Pax River dates back to 1942 when the United States Navy acquired land in St. Mary's County for the establishment of a naval air station. Construction began in 1943 and the base was commissioned in 1943 as Naval Air Station Patuxent River. Throughout World War II, NAS Pax River played a critical role in testing and evaluating new aircraft and weapons systems for the Navy.

In the post-war years, NAS Pax River continued to expand and evolve as a center of excellence for naval aviation research and development. The base became known for its testing of cutting-edge aircraft and technology, including the development of the Vought F7U Cutlass, the Grumman A-6 Intruder, and the Sikorsky SH-3 Sea King helicopter.

Today, NAS Pax River is one of the premier naval air stations in the United States, encompassing over 6,400 acres of land and supporting a diverse array of military and civilian operations. The base is home to a wide variety of aircraft, including the F-18 Hornet, the E-2 Hawkeye, and the P-8 Poseidon, as well as a number of unmanned aerial systems.

One of the key functions of NAS Pax River is to serve as the home of the Naval Test Pilot School (NTPS), which provides advanced training to military test pilots and flight test engineers from the United States Navy, Marine Corps, and Air Force, as well as allied foreign nations. The NTPS offers a rigorous curriculum that includes classroom instruction, simulator training, and hands-on flight testing in a variety of aircraft.

In addition to the NTPS, NAS Pax River is also home to the Atlantic Test Range, a vast airspace and sea range used for testing and evaluating aircraft and weapons systems. The range encompasses over 1.2 million square miles of airspace and 17,000 square nautical miles of sea space, providing an ideal environment for conducting a wide range of flight tests and training exercises.

NAS Pax River is also a hub for research and development in naval aviation, with a number of specialized laboratories and facilities dedicated to testing and evaluating new technologies and systems. These include the Aircraft and Propulsion Integration Lab, the Air Combat Environment Test and Evaluation Facility, and the Rotary-Wing Aircraft Test and Evaluation Division.

In conclusion, Naval Air Station Patuxent River is a vital and dynamic military installation that plays a crucial role in advancing the capabilities of the United States Navy and Marine Corps. From its humble beginnings in World War II to its current status as a cutting-edge center for aviation research and development, NAS Pax River has a proud history of excellence and innovation in the field of naval aviation. With its world-class facilities, talented workforce, and strategic location, the base is well-positioned to continue its mission of supporting the fleet and safeguarding the nation's security for years to come.
