FAB-50

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 used Picric acid instead. At least 25 variations of the FAB-50 were produced. 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. FAB-50 bombs were used in numerous quantities, and unexploded bombs are still being found in Ukraine and Russia.

This is only a partial list. • FAB-50 Bombs • 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 the Polikarpov 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 the Siege of Sevastopol (1941–1942). The Romanian 152mm shells proved popular and stocks were eventually used up during the war.
