The Nora B-52 is a 155 mm/52-calibre self-propelled howitzer weapon system developed by Vojnotehnički Institut (Military Technical Institute Belgrade, Serbia, then Yugoslavia) for export and domestic use. The first self-propelled Nora B (developed on the basis of Nora C) was designed by MTI in 1984 (at that time no other country except Yugoslavia had that kind of weapon today known with acronym TMG - Truck Mounted Gun) with a modified 152 mm towed gun-howitzer NORA M84 [2] with 45 caliber gun mounted on an FAP 8x8 truck bed and was 3 generation of artillery weapons.

Later after 2000 MTI developed new versions 4 generation artillery systems with 52 caliber 155 mm gun for fitting on a new system of NORA family with B-52 designation.

Variants[edit]

B-52 operation depending on version is fully automated, including a 36-round autoloader. It is made in several versions:

  1. K0 (first serial variant, open turret, manual power drive and light of sight)
  2. K1(S) (differences from K0:semi-open turret, full automatic, independent automatic navigation, automatic fire and control system, smaller crew number)
  3. M03 (semi-open turret, automatic based on K0,K1 designs with S designation for Serbia Army)
  4. KE (semi-open turret, full automatic export variant)
  5. K-I (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 S for Serbia
  6. Newest in development 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).

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 MRSI 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.[3][4][5]
