The FAB-50 (fugasnaya aviatsionnaya bomba, фугасная авиационная бомба, ФAБ-50) is a series of unguided general purpose Soviet and Russian aerial bombs created before and during World War II.
The basic FAB-50SV bomb consisted of two sections steel forged into a teardrop shape and welded together.
All were armed by a single fuse (varied depending on type) matched to a propeller screw arming mechanism and were mounted via a single steel strap which made it possible to attach to almost any bomb rack available.
TNT was the most commonly used high explosive charge, but some bombs used Picric acid instead.
[1][2][3][4] On 17 September, 1942 the State Defense Committee issued decree number 2313 SS which stipulated increasing the number of completed FAB-50 bombs to 10,000 in September and 25,000 in October of that same year.
