The AN/PVS-5 is a dual-tube night-vision goggle used for aviation and ground support. It uses second-generation image-intensifier tubes. The United States Army still has PVS-5 on supply but are very rarely used. The AN/PVS-5 is based on the SU-50 which was a first-generation night-vision goggle adapted by the United States Air Force in 1971. From 1972 until 1990 the AN/PVS-5 was the mainstay in US Army night vision for aviation. The AN/PVS-5C was not approved for flight because of its high-light cut off feature causing the goggle to shut off in bright light. For ground troops the AN/PVS-5 was the sole night-vision goggle until the adaptation of the improved AN/PVS-7.
By today's standards, the PVS-5 was a safety risk for pilots. Issues such as a limited field of view, poor light amplification, inability to read maps, and its excessive weight made it difficult to fly while operating them. In 1982, tests were being made for a suitable replacement for the AN/PVS-5 specifically for aviation. This led to the adaptation of the AN/AVS-6 ANVIS in 1989. The ANVIS was the first night-vision goggle used by the United States Army specifically designed for aviation.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/PVS-5" designation represents the 5th design of an Army-Navy electronic device for portable visual detection equipment. The JETDS system also now is used to name all Department of Defense electronic systems.
