2B23 - also known as "Nona-M1" - is a Russian drawn mortar . It was developed in the Central Research Institute for Precision Mechanics (АО «ЦНИИТОЧМАШ») in the city of Klimovsk and is produced in the Motovilicha factories in the city of Perm.
history
In 2000, the Headquarters for Missiles and Artillery gave the task of developing a new towed mortar , called the "Nona-M1". The "Central Research Institute for Precision Mechanics" (ЦНИИточмаш) was appointed as the main developer. The ballistic properties of the 2A51 cannon and the mortar of the 2S9 “Nona-S” self-propelled gun were adopted in the mortar construction , which allowed the use of the same projectiles. The carrier plate was developed by the "Central Research Institute (Буревестник)". The first prototypes were produced in the Motowilicha works.
In 2003, the 2B23 mortar went through the acceptance tests, after which some improvements were necessary in the design office. This concerned the construction of the carrier plate and the barrel, which is used in the analog version in the 2S31 self-propelled gun . From May to September 2004, the 2B23 mortar was subjected to preliminary tests on the Rzhevsky artillery field near Saint Petersburg . In 2005, the mortar went through tests under the supervision of the Ministry of Defense, and after critical objections, the construction had to be reworked again. Finally, in 2007, the 2B23 mortar entered the service of the Russian armed forces . Only then was the first series produced.
description
The main use of the 2B23 mortar is in fighting infantry, as well as lightly armored and non-armored vehicles. The mortar batteries of the mechanized infantry battalions as well as the paratroopers' units were to be equipped with it, since the mortar can be dropped from an aircraft using a special drop device.
The 2B23 mortar consists of five main elements:
- Run;
- Frame with lock;
- Carriage on wheels;
- Base plate;
- Target acquisition "МПМ-44М".
The barrel of the 2B23 mortar has a twist with 40 puffs. A cylindrical cartridge chamber is located in the breech unit . A cartridge frame is installed on the charging section of the barrel to connect the barrel to the loading and breech unit . A coupling piece for train with a towing vehicle is attached to the muzzle.
The 2B23 mortar as a whole connects the frame and the locking mechanism. The construction resembles a box in which the barrel was mounted. The box is connected to a pin frame . A locking pin is attached to the frame with a rod. For loading a bullet, the barrel is rotated vertically in the box and installed in the horizontal position. The opening mechanism activates the fire mechanism. The construction of the mount has a suspension with a torsion pendulum and is connected to the frame. The wheel track can be changed by adjusting the axle rod in the horizontal position. The base plate is a modified version of the 2B11 grenade launcher, which is part of the 2S12 Sani system.
For target detection of 2B23-mortar is used the modified version of the visor МПМ-44М that which consists of two visor elements collimator -K-1-visor with Kollimatorskala and the additional laser ЛУЧ-ПМ2М .
The ammunition used includes the following types of Soviet or Russian production,
- Projectiles with a combined warhead with fragmentation and explosive elements such as the so-called "rocket-assisted projectile" 3ВОФ55-1 with a remote detonator and a weight of 19.8 kg reach a range between 0.7 and 12.8 km Devastate free areas of 3600 to 5400 m² and an area with armored technology of 3400 to 5100 m².
- Thermobaric projectiles such as the 3ВОФ119 projectile with a weight of 19.5 kg achieve a range between 0.9 and 8.8 km.
- Precision-guided ammunition such as the "Kitolow" artillery shell with a weight of 25 kg has a range between 9 and 12 km.
- Projectiles with a warhead made of incendiary elements such as the 3ВЗ4 projectile weighing 16.3 kg have a range between 0.45 and 5.7 km.
also all 120 mm projectiles of the 2A51 cannon of the 2S9 self-propelled gun.
