Description


Introduction

The M84 is a towed howitzer of Yugoslav origin. It was developed in the early 1980's to answer the need for a longer range than provided by the elderly D-20 towed howitzer. The M84 is also known as the NORA-A.

Design

The M84 uses the same two wheel split trail chassis as the D-20 but is fitted with a new 152mm 40-caliber ordnance. The ordnance is much longer than the one used on the D-20 and features a new breech system. A shield gives the crew of 9 some protection from small arms fire over the frontal arc.

Firepower

The M84 fires the same Soviet 152mm shells as the original D-20, but out to a much longer range. Standard 152mm ammunition can be fired out to 17.2 km or a new M84 projectile out to 24.2 km. A burst rate of fire of 8 rpm can be achieved or a sustained fire of 5 rpm.

Mobility

The M84 is normally towed by 6x6 truck. In (former) Yugoslav service the FAP 2026 6x6 truck was used. Emplacement time is 3 to 5 minutes. The weapon is too heavy to be manhandled.

Users

About 100 M84 have been produced and are in service with several former Yugoslav nations. The M84 was never exported.

The M84 comes in three versions that are very similar in performance. The M84 can be easily identified by its D-20 chassis in combination with the much longer 152mm ordnance.
