TheFAB-50 (fugasnaya aviatsionnaya bomba, фугасная авиационная бомба, ФAБ-50) is a series of unguided general purposeSoviet and Russian aerial bombs created before and duringWorld War II. The FAB-50 series was widely used by theVVS during World War II. They consisted of both conventional bombs and modified artillery shells. The earliest models weighed 49.67 kg, but could weigh over 63 kg by 1943, depending on the variant. 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. Fuses used included the AV-1, AV-1d/u, & ADP screw driven fuses.TNT was the most commonly used high explosive charge, but some bombs usedPicric acid instead. At least 25 variations of the FAB-50 were produced.[1][2][3][4] On 17 September, 1942 theState 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.[5]
FAB-50 bombs were used in numerous quantities, and unexploded bombs are still being found inUkraine and Russia.[6][7][8][9][10][11]

|---|---|---|---|---|---|---|
| Designation | Diameter (mm) | Length (mm) | Bomb mass (kg) | Explosive mass (kg) | Notes | |
| FAB-50SV | 240 | 941 | 49.76 | 26.35 | Forged steel body, riveted tail fins. | |
| FAB-50ShG | 240 | 938 | 49.6 | 26.35 | Riveted five-piece steel body. | |
| FAB-50TsK | 219 | 950 | 60 | 25 | Cast steel, tail fins riveted. | |
| FAB-50SL | 219 | 950 | 63-65 | 25 | Cast steel, tail fins riveted. Very similar to the TsK but manufactured at the Rostselmash factory. | |
| FAB-50SCh | 219 | 920 | 65.4 | 24 | Cast steel, tail fins mounted by steel strap. Production started in 1943 as beefed up version of TsK. | |
| FAB-50m9 | 152 | 966 | 42 | 8.8 | 152mm artillery shell modified into a bomb. Production started in 1935/1936. Limited production, primarily used by thePolikarpov Po-2. | |
| FAB-50TR | 105-152 | 920 | 45 | Varied | Captured French, British, German, and Romanian artillery shells modified into bombs. Tail fins clamped on and often created by field units. Bombs of this type were made and used during theSiege of Sevastopol (1941–1942). The Romanian 152mm shells proved popular and stocks were eventually used up during the war. | |
