The FAB-250 bomb is a Soviet-origin 250 kg general-purpose aviation-bomb family covering M46, M54, and low-drag M62 body patterns. The baseline free-fall bomb body is documented separately from the later FAB-250 UMPK fitted glide-bomb configuration.

Designation Notes

FAB-250 is a 250 kg-class family label rather than one fixed bomb body. Open references separate M46, M54, and M62 patterns, so dimensions, fuzing, and explosive weight should be read by model when a source identifies one.

M62 shape

Weaponsystems.net describes the M62 series as a more aerodynamic early-1960s FAB family for higher-speed aircraft carriage.

Explosive weight

The JMU ordnance guide lists about 104 kg net explosive weight for FAB-250 M46 and about 107 kg for FAB-250 M62.

Fitted-kit boundary

The UMPK-equipped configuration is separated because Defence Express describes a FAB-250 free-fall bomb body converted with a glide-and-correction module.

Variants

FAB-250 is a nominal 250 kg-class bomb-family designation. The M46, M54, and M62 suffixes identify related Soviet body patterns with different aerodynamic shapes, fuzing, and explosive-weight details.

WeaponsSystems.net describes the FAB M62 series as a Soviet free-fall bomb family with a common 250 kg version produced by Bazalt, while direct conflict reporting links FAB-250-class bombs to Azerbaijan's converted An-2 aircraft in 2020 and to Russian and Ukrainian strike adaptations in the 2014 Russia-Ukraine War.
