Modern solutions have been applied in developing II generation shells. These include: optimised aero-dynamic shape securing external ballistic characteristics, accuracy and precision at all ranges; appliance of advanced shell body manufacturing technology which provides forming of a great number of fragments, has been applied in production of the shell body; this technology, together with the TNT/RDX explosive charge provides optimum efficiency at target. The new generation shell weight corresponds to the heavy shell weights of the previous generation and importantly increased their range, precision and terminal efficiency.
Masking of friendly troops movement as well as blinding of enemy observers, fire support artillery and anti-tank weapon crews is achieved by use of modern, low-drag and highly efficient white phosphorus - based smoke shells.
With use of illuminating mortar shells, mortars provide night battlefield illumination, as well as blinding of enemy crews and observers.
Antisabotage underwater - operating HE mortar shells, developed in 81/82mm caliber, with special point-detonating, superquick and delay-action fuses significantly expand the tactical use of mortars - providing antisabotage underwater operation through the shock wave action against saboteurs-diving commandoes, clearing of underwater mine fields - with the purpose of initiating a particular type of mine sensor in underwater mine-field through the action of shock-wave, as well as antilanding operation - by fragmentation effect on the water-sea surface or land, with the purposse of annihilating personnel and unarmoured vehicles and equipment. The antisabotage mortar shells characterize fuze delay time from 0.09 to 0.19s, depth of underwater burst from 4 to 10m and shock wave intensity in the water of 16 x1003Pa at the distance of burst site of 20 m and 10x 103Pa at the distance of burst site of 30 m.
The shells are completed with fuzes which are also indigenously produced: point detonation, superquick/delay fuzes, time pyrotechnical fuzes, time electronic digital fuzes with permanent memory and non-contact timing, and proximity, radar-doppler fuzes.
The propellant charge consists of base and increment propellant charges. The base propellant charge is filled with double-base NGB powder (ballistite) fitted into a cardboard bushing. The increment propellant charge is also filled with NGB powder fitted in 6 reinforced celluloid shells resulting in a good distribution of the projectile initial velocities and good range overlapping.
