Remarks: National Museum of the US Air Force. This was the original AC-130 prototype, a side-firing gunship based on the venerable C-130. It was initially equipped with four 20mm and four 7.62mm multi-barrel guns, a searchlight, and target sensors. Later it was used as a test bed for additional armament, sensors and fire control development. The radome underneath the cockpit windows contained a Magnetic Anomaly Detector (MAD) system called the Black Crow (AN/ASD-5).
Remarks: National Museum of the US Air Force. Another unique plane in the museum's R&D Gallery. The Total In-Flight Simulator (TIFS) was used to study how an aircraft would fly before building an expensive prototype. It could be configured with two different noses. The first one was a 2-person cockpit from which onboard computers simulated the handling of various aircraft. The second one could carry a wide array of radars, cameras and other sensors.
