AN/PVS-2

The AN/PVS-2, known as the "Starlight Scope," was one of the first widely used night vision devices in the US military, particularly during the Vietnam War. It was a significant advancement because it was a passive night vision device relying on ambient light like moonlight or starlight. This allowed soldiers to see at night without revealing their position to the enemy.

The AN/PVS-2's development began in 1964, with initial models reaching troops in 1967. It became a common sight in Vietnam by 1969, significantly enhancing night operations for US soldiers. Unlike earlier night vision systems, the AN/PVS-2 did not need an infrared illuminator. It amplified existing light, allowing for stealthy observation and engagement. Early models suffered from "blooming," where bright light would temporarily cause the scope to "white out." Later versions addressed this and improved battery life to around 100 hours. Although replaced by more advanced night vision technology, the "Starlight Scope" holds a significant place in the history of night vision, representing a major step forward in making night operations more feasible and effective.
