Manufactured in two versions, the first NORA B-52 mounted a modified Russian 152mm (calibre Length 45) D-20 Howitzer main gun on a wheeled 8×8 FAP 2882 truck chassis. The vehicle has a forward cab and compartment for the 5 man crew and behind this is the ammunition storage for 40 rounds. The main gun is mounted on a powered traversable mount with a large gun shield. Some publications state this is in service with the Serbian Army, however it is not listed on their official website.

The vehicle has a modern fire control system and can be fitted with navigation/pointing equipment.

The vehicle uses a KamAZ 63501 8×8 wheeled truck chassis with a crew a cab and behind this is the storage for ammunition. A total of 36 rounds are stored. there are four hydraulic legs on the vehicle used to stabilise the vehicle when firing.
