Photoflash bomb (photoflash bomb, flash bomb) is an aviation bomb that creates a powerful short-term light flash.

The main charge of the FOTAB is made of a powdered aluminum-magnesium alloy called a photo mixture. An ignition-explosive charge (VRZ) consisting of a mixture of an oxidizer and aluminum powder with magnesium is installed along the axis of the aerial bomb. It is activated by a remote fuse. The explosion of which destroys the body of the aerial bomb, the photo mixture is scattered, ignited and burned using air oxygen. FOTAB 100 kg creates a flash with a light intensity of more than 2 billion candles with a duration of about 0.2 seconds.

It is designed to illuminate the terrain during night aerial photography from an airplane from altitudes up to 10,000 m, at flight speeds up to 1000 km / h. Due to the advent of improved night optics, satellite images and stealth aircraft, these bombs are no longer used by the military.
