Serbian NORA-B52 has been down selected for Test and Evaluation by the US Army for new mounted fully automated Howitzer capability
WASHINGTON — Participants are emerging for the U.S. Army’s mobile 155mm howitzer shoot-off coming up in early 2021 at Yuma Proving Ground, Arizona.
Serbian Yugoimport SDPR announced in December 2020 it had been chosen to bring its NORA-B52 to the evaluation.
And BAE Systems, Nexter and Israeli’s Elbit Systems announced they too had been chosen to bring offerings to the shoot-off.
AM General has also publicly expressed their interest in participating in the shoot-off. Other possible offerings could come from South Korean defense company Hanwha and Japan’s Mitsubishi. Other contenders could be the South African 6×6 Rhino or the Slovakian 8×8 DANA.
The Army is looking for a production-ready system that offers an improvement in range, rate-of-fire and mobility over the artillery systems used within Stryker Brigade Combat Teams now. The service released an announcement in July seeking a more mobile, lethal and survivable replacement for its current towed howitzers and described its plan for a three-month-long shoot-off.
Participants must provide 18 evaluation systems for the event, according to the solicitation. The Army would like the selected company to begin delivering systems in the first quarter of fiscal 2023.
Global Military Products also announced Dec. 17 that the U.S. Army had chosen its Serbian partner Yugoimport’s NORA B-52 155mm wheeled howitzer for the shoot-off as well.
NORA has a fully automatic autoloader and a “move-shoot-move while under armor” capability, according to the statement. NORA has undergone modernization and upgrades over the past several years “that are sure to get the attention of the U.S. Army” the statement adds.
NORA B-52 is a self-propelled gun-howitzer developed to replace older artillery systems in service worldwide. First 12 NORA B-52’s were delivered by Yugoimport SDPR in 2007 and more systems of this type were ordered across Europe, Asia and Africa. This artillery system has been exported to Bangladesh (18), Burma (Myanmar) (30), Cyprus (unspecified number) and Kenya (30). Serbian Military recently declared Full operational capability for NORA B-52.
NORA B-52 is fitted with a 155 mm/L52 gun-howitzer. NORA B-52 fires all standard NATO 155 mm ammunition. It is fitted with an automatic gun loader enabling rate of fire of 6 rounds per minute. Vehicle carries a total of 36 rounds of ammunition. Autoloader holds 12 rounds. Maximum firing range is 20 km with ordinary projectile and 41 km with rocket-assisted projectile.
The First NORA B-52 artillery systems were mounted on the FAP 2832 truck, built under Mercedes-Benz license. However it was soon replaced in production by improved systems. The capability can be mounted on any 8×8 trucks chassis vehicle.
Armoured version of the NORA is also available. It provides protection against small arms fire and artillery shell splinters. Vehicle withstands 6 kg TNT blasts anywhere under the hull. There is also an NBC protection system for the crew. It is claimed that this version is capable of multiple round simultaneous impact firing.
NORA B-52K2 was a significantly improved version. This 155 mm howitzer was fitted with a fully-automatic ammunition loading system. This artillery system was first publicly revealed in 2017. Eventually the NORA B-52K2 has been renamed as the MGS-25 Aleksandar.
One fully equipped battery usually consist of 6-12 self-propelled howitzer, reconnaissance 1-2 BOV M11, three command BOV M10(1 for each platoon and 1 for battery command), 3-6 munition trucks, communication and workshop vehicle, 2-3 general supply vehicles (fuel, food, water etc.) and 1-2 fire direction and gunfire locator vehicle with radar and sound ranging.
NORA-B52 155mm self-propelled gun-howitzer set includes:
- armament subsystems,
- modified off-road vehicle subsystem,
- hydraulic subsystem with belonging back-up subsystems,
- breechblock pneumatic installation subsystem,
- electrical power subsystem,
- weapon fire control system (FCS),
- fire protection subsystem,
- ventilation, air-conditioning and heating subsystem,
- subsystem of communication between crew members,
- stand-by power unit (motor and pump).
NORA-B52 155mm self-propelled gun-howitzer meets the following mobility and passability requirements:
- maximum speed on a level asphalt road is 90 km/h
- maximum speed on a level macadam road is 40 km/h
- maximum off-road speed is 15 km/h
- trench width is 1600mm
- maximum gradient is 50%
- maximum side slope is 20%
- range of movement on a level road (asphalt or good macadam road) to is 500 km
- fording depth is 1.0m
- vertical obstacle height is 0.50m
- minimum turning radius is 16.6m
- flat-tire driving range to is 50 km
NORA-B52 155mm self-propelled gun-howitzer should have the following armament:
- primary armament: 155mm gun with a 52-caliber barrel, installed in a turret (partly armoured) on a modified chassis of an off-road vehicle (12 projectiles and 12 propellant charges in the automatic loader and 24 projectiles and 24 propellant charges in the ammunition containers behind of cabin),
- secondary armament: – 12.7mm machine gun with a cupola,
- smoke pot launchers (two groups with 82mm launchers each, installed in the front part of the vehicle cabin),
- training armament: coupled 20mm M55 gun.
The gun mode of fire:
- fire mode is 12 rounds in 4 minutes.
- barrel ballistic life – 1000 rounds with charge 10 at the table conditions
- with frettage barrel – 1500 rounds with charge 10 at the table conditions
The vehicle ground support system during firing and the mechanisms for movement of the self-propelled 155mm gun-howitzer provide:
- the basic direction of fire – contrary to the direction of driving:
- field of action in elevation from – 5 to +65 with the speed of the barrel movement in elevation of ≥8/seconds,
- total field of action in azimuth of minimum 60 (with approximately equal rotation in both directions from the longitudinal axis of the vehicle) with the speed of the barrel movement in azimuth of ≥ 6/seconds,
- auxiliary direction of fire – in the driving direction:
o field of action in elevation from + 25 to +65,
o total field of action in azimuth of minimum 50 (with approximately equal rotation in both directions from the longitudinal axis of the vehicle).
The combat mass of the NORA-B52 gun-howitzer, with a 0.5 combat set and the crew members, does not exceed 36 tons.
The number of crew members of the NORA-B52 self-propelled gun-howitzer is 5 (commander, gunner, driver and two crew members).
A part of the fire control system is integrated on the NORA-B52 self-propelled weapon, which, together with the fire control system on the levels of the battery and division, enables efficient use of the weapon.
The fire control system on the battery level enables the use of the weapon in several ways, and specifically:
- in the automatic operation mode (automatic line of sight),
- in the semi-automatic operation mode,
- in the classical-manual operation mode.
The weapon part of the fire control system includes:
- a unit for inertial navigation, orientation and laying in the basic direction,
- a unit for determination of the relative location of the weapon,
- communication equipment,
- the unit for communication between the crew members,
- PLC unit,
- indicators of the firing elements and other information with computers (commander’s and gunner’s counters),
- a set of sighting devices for indirect and direct firing with accessories for their lighting,
- a collimator for each weapon for marking the basic direction in the classical –manual operation mode.
