underground inertial facility is maintained and operated by the Penn State Applied Research Lab (ARL). The runway at the base was able to accommodate the C-5 Galaxy military cargo aircraft. Today The former Center is now home to an industrial park, Warminster Community Park, a housing development, the new Bucks County morgue crime lab, Ann's Choice, a senior citizens' housing complex and the IHG hotel "Holiday Inn Express". Stormtracker6, the Doppler weather radar for WPVI is also located there. While once part of the EPA's superfund list, the US Navy has completed all cleanup activities at the former base. In 2014, the Warminster Municipal Authority issued a public notice stating that groundwater contamination has been identified on and in the area for the former NAWC site and shut down two supply wells as result of the contamination until further notice. The water is contaminated with perfluorooctanesulfonic acid. Contamination was detected in other wells but not above the EPA's provisional Health Advisory Level. Human centrifuge Since Johnsville possessed the world's largest human centrifuge, capable of spinning a man to at least 16g, (42g max 19g/s onset) it was used for astronaut training. The centrifuge was later used for flight simulation where it could simulate 6 degrees of freedom with g loading. The F-14 flat spin on takeoff issue was investigated and resolved on the DFS centrifuge. Later endeavors included supine seat experiments, G-Tolerance Improvement Program (GTIP), and F/A-18 simulation. The DFS centrifuge building (formerly building 70) has been refurbished as a museum, office space and a theater.
