This is a unified planning bomb cassette that is capable of defeating without the aircraft entering the zone of direct action of the enemy’s air defense weapons and delivering highly accurate self-aiming ammunition to the target. The planning bomb cassette PBK-500U SPBE-K is designed for all-weather use at any time of the day.
As an effective ammunition, the PBC-500U SPBE-K can be used against armored vehicles, anti-aircraft missile systems with thermal or radar contrast under the influence of natural and man-made interference.
The ammunition is produced by NPO Basalt. For the first time, the PBC-500U SPBE-K bomb cassette was presented in the city of Zhukovsky during the MAKS-2015 international aerospace show.

Sergey Rusakov quotes RIA News:
We estimate that this type of ammunition can be exported from 2017 onwards.
The cartridge has a modular design and, depending on the purpose, can be equipped with different military elements, including high-explosive fragmentation, concrete-breaking or incendiary. Antitank "filling" is also used. Effectively used by frontline aircraft aviation.
