Yugoimport NORA B-52 155 mm/52-calibre self-propelled gun (Serbia), Self-propelled guns and howitzers (wheeled)

Development
Following extensive trials over several years with a testbed of a 155 mm/45-calibre 8 × 8 Self-Propelled Gun (SPG), Yugoimport then commenced work on a new 155 mm/52-calibre system with the first prototype completed in 2003. This is designated the NORA B-52.The first testbed is designated the self-propelled 155/45 mm NORA B M96 and is fitted with a 155 mm/45-calibre barrel that, firing an Extended-Range Full-Bore Base Bleed (ERFB-BB) projectile M98, enables a maximum range of 39 km to be achieved.Late in 2004 it was disclosed that development of the NORA B-52 155 mm/52-calibre self-propelled gun had been successfully completed and an undisclosed customer had placed the first export order for an undisclosed quantity of systems.While first examples of the NORA B-52 155 mm/52-calibre (8 × 8) self-propelled artillery system were based on a locally developed chassis the first production systems, for an unidentified export customer, were based on a KamAZ 63501 (8 × 8) cross-country chassis.Unconfirmed reports have indicated that the first export customer is Myanmar with first batch of vehicles delivered. In late 2011 it was stated that Bangladesh had placed a contract for a total of 18 NORA B-52 155 mm/52-calibre self-propelled guns and that these would be fitted with a SAGEM Sigma 30 inertial navigation platform system for autonomous navigation and pointing.

Description
The platform used in the original system is based on a locally designed and manufactured FAP 2882 (8 × 8) cross-country chassis with a forward control cab that was originally developed as a cargo truck but was subsequently used for a wide range of other applications. This includes the 262 mm (12-round) LRSV M-87 'Orkan' multiple rocket launcher, which is covered in a separate entry.This 8 × 8 chassis has good cross-country mobility and is fitted with a central tyre-pressure-regulation system that allows the driver to adjust the tyre pressure to suit terrain being crossed. The fully enclosed forward control two-door cab can be tilted forwards to allow access to the power pack for maintenance purposes.Some of the SPG crew are carried in the cab with the remainder being seated in a fully enclosed pod to the immediate rear of the cab. To the rear of this is ammunition stowage that carries 36 155 mm projectiles, combustible charges and fuzes.The 155 mm/45 mm-calibre ordnance is mounted on a turntable at the very rear of the chassis with a shield, and is normally traversed to the front to reduce the overall length of the system for travelling.When deployed in action the weapon is normally fired over the rear arc. The prototype chamber has a capacity of 22.5 litres with the ordnance having 48 grooves and maximum pressure of powder gases being 3,000 bars.To provide a more stable firing platform, four hydraulic stabilisers are lowered to the ground by remote-control, two
