Sampson Air Force Base is a closed United States military facility, last used by the United States Air Force Air Training Command as a Basic Military Training Center. It was closed in 1956 and put into caretaker status. As of at least the 2000s, parts of the facility have been converted to a civil picnic area called Sampson State Park. In addition, the United States Navy operates the Naval Undersea Warfare Center (NUWC) sonar test facility on a part of the facility. However, most of the former base is abandoned.
