THE FOUR FACES OF NONA: MORTARS WITHOUT EQUAL

Specialists throughout the world appreciate the need to equip high mobility combat units (paratroops, airmobile and naval infantry) with a powerful artillery system that can correspond to ways of their shipment and mobility in terms of their marching and maneuvering characteristics. Such systems had been developed in some

countries, however, a dramatic breakthrough was achieved by Russian designers of the Precision Mechanical Engineering Central Research Institute (TsNIITochMash). Jointly with a number of design bureaus, institutes and plants TsNIITochMash created the Nona-S (2S9) unique, completely armored, breech-loaded artillery system with a filter-ventilated unit.
This artillery system was mounted on the chassis of the BTRD updated airdropped tracked armored personnel carrier. This engineering solution was prompted by the need to drop the artillery system together with the BMD airborne combat vehicles. Primarily, it allowed these artillery systems to be dropped together with BMDs via jet parachute systems, with the crews inside the vehicles. Also, this solution facilitated their joint combat use, owing to the availability of the tracked chassis and armor plating.
TsNII TochMash's designers developed a new design-ballistic concept "cannon - round" which stood out owing to the use of ammunition with ready-made grooves on the driving band of the projectile.Constructionally, the round intended for breech-loaded cannons and mortars consists of an explosive charge in the form of a cartridge arranged on the cannon primer, with the diaphragm in its rear part resting on the tapered part of the barrel before firing. On the front part of the cartridge, the primer has elements of the locking device and the projectile with a fuze. Before firing, an explosive charge and projectile are coupled via the locking device to form a fixed round convenient for loading.
