OVERVIEW: Optical sights for tail guns were widely used from WWII through the early Cold War, enabling manual targeting of enemy aircraft. These devices relied on direct visual tracking with basic mechanical range estimation and crosshair aiming.

GENERAL DESCRIPTION: Tail gun optical sights were manually operated visual targeting devices used by gunners aboard bomber aircraft. Typically composed of a glass optical tube or reflex sight with fixed or adjustable reticles, they allowed the gunner to align and fire weapons at approaching enemy aircraft. While lacking rangefinding or stabilization, these systems were simple, durable, and effective at close to medium range.
