The Nora B-52 is a 155 mm self-propelled howitzer weapon system developed by Military Technical Institute Belgrade for export and domestic use. The first self-propelled Nora B (developed on the basis of Nora C) was designed by MTI in 1984 with a modified 152 mm gun-howitzer M84 NORA mounted on an FAP 8x8 truck bed and was a third generation of artillery weapons.

Later 2000 MTI developed new versions of 4th generation artillery systems with 52 caliber 155 mm gun for fitting on a new system of NORA family with B-52 designation.
B-52 operation depending on version is fully automated, including a 36-round autoloader. It is made in several versions:
- first serial variant, open turret, manual power drive and line of sight.
- differences from K0:semi-open turret, full automatic, independent automatic navigation, automatic fire and control system, smaller crew number.
- semi-open turret, automatic based on K0,K1 designs with S designation for Serbia Army.
- semi-open turret, full automatic export variant.
- K1 with additional armored full automatic with closed turret, new stronger chassis, radar on barrel for measuring projectile trajectory and speed, NBC protected cabin and turret, automated fire-suspension system, smoke grenade launcher, intercom for crew and new software, designated M15 for Serbia.
- MGS-25 Aleksandar
- Newest version planned since 2009 is designated as K2 (25 liter chamber, higher rate of fire, laser guided long range ammunition, smaller crew, new automated functions, smaller weight~25 tonnes, automatic leveling of gun in north direction,new smoke and light grenade) with development started later probably in 2012. As of 2017 at international arms fair Partner 2017 in Belgrade and after a few years of development it was presented newly developed prototype model named "Alexander", It has a new designation now and instead K2 it is called MGS-25 named "Alexander" and comes with 12 rounds ready for fire in a revolver type of automatic loader and has 12 additional ammunition that are stored in a storage box located at back behind the crew cabin and engine-hydraulic compartment. The automatic loading system can reloaded ammunition compartment in a back of a gun. MGS-25 has a rate of fire of 6 rounds per minute and can continue firing operations until all ammunition is used. The Aleksandar has a maximum firing range of 32,5 km with standard ammunition and 56 km with the 155 mm HE ERFB RA/BB (VLAP). It can use all available ammunition on market for 155mm howitzers designed to withstand pressure in a new larger chamber. MGS-25 can be remotely controlled by crew via separate remote control up to 100 meters from vehicle thanks to high level of automation of all functions. As fully autonomous module it can be mounted on different trucks chassis - Kamaz and MAN versions presented until now.
K designation stands for Kamaz chassis, number for orientation of main weapon in relationship to north and letter for level of equipment and/or export designation. It is possible on demand to equip Nora B-52 howitzer with 152 mm gun.
All versions have differences in chassis, armour, turret, loading and support system. All versions with automatic loader features Multiple Rounds Simultaneous Impact capability. Standard equipment includes a computerized fire control system and a land navigation system. Ballistic protection is provided against small arms fire, shell splinters and some mines.
For training and simulation purposes special computer simulator  was developed by Mihajlo Pupin Institute that includes terrain maps of customer country with ability to train up to 3 battery of Nora B-52 or up to division of 18 gun, including crews for artillery designation on targets.
Special truck chassis upgrade as resupply vehicle for ammunition reload was developed and used within battery of Nora B-52 self-propelled howitzer.
Serbia has exported the Nora B-52 artillery battlefield systems (B-52 selected versions of self-propelled howitzer K1, KE, KI), reconnaissance BOV M11, command (BOV M10) and battery fire control and meteorological vehicles, ammunition loading trucks, artillery battlefield software for platoon, battery and division level) to the armed forces of Myanmar, Kenya and Bangladesh. 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. With latest order for Cyprus instead BOV M11 the new BOV M16 Miloš was delivered as artillery reconnaissance and artillery battery command vehicle.
There are various type of ammunition available that includes domestic and foreign 155mm projectiles as it is JBMOU-compatible. Depending on ammo used different maximum ranges and effects on target can be achieved.
