T-80 fitted with "Burlak" combat module

Image
Recently new images came to light, of a T-80 equipped with a familiar-looking combat module. Closely resembling the "Burlak" combat module which was previously mounted on a T-72B hull back in the early 2000s.  On the photographs, it can be easily identified that the hull is the same as on the Object 219M "T-80BV-RM" which one of the prototype T-80BV upgrades made by Russia more than 10 years ago.    The design of the turret is very similar to the "Burlak" CM, made back in the early 2000s by Omsk KBTM, now known as Omsktransmash. The turret itself seems to be in a more complete state, with a more refined turret design and finalized components.  It sadly is unknown when this variant was tested and will it ever be accepted into the armoured forces. But the images show that the development of a new combat module has been continued past the "Burlak" and its presence on other vehicles other than the T-72B. 

Сalculation of radiation protection of AFVs

This is a continuation and expansion of the previous article. If you haven't read the previous article which covers Anti-radiation material usage in Armoured Fighting Vehicles, it is recommended to read it first. That article will cover the basics of AFV protection against radiation. While this page will expand upon it with the explanation and theory behind calculating radiation protection of AFVs, and is not required to be read to understand what was mentioned in the previous article.  Сalculation of radiation protection of AFVs. The methods of calculating radiation protection for tanks are based on the principle of superposition with the concept of albedo doses, according to which the dose in the calculated biological hotspot is considered as a set of radiation doses passing through individual structural elements. Increasing the dose in already calculated points inside an object, which results in increased amounts of radiation reflection includes the usage of the albedo coefficie

The latest self-propelled artillery gun (SPG) 2S43 "Malva" will enter the state testing stage next year, 2022. This is reported by RIA Novosti, citing a source in the military-industrial complex. According to the source, in 2021, the prototype of the SPG will pass acceptance tests, during which the compliance of the gun with the requirements of the technical specification will be confirmed. State tests are scheduled for 2022. According to the source:  "As part of the acceptance tests, which will begin in the spring or summer of this year, the "Malva" must shoot a certain number of shells, as well as pass the tests of the chassis on various soils. Factory tests of the SPG were completed at the end of 2020." SPG 2S43 "Malva" is being developed by the Central Research Institute "Burevestnik" within the framework of the ROC "Набросок" - "Sketch". For the first time, the howitzer was presented in 2019 in closed mode, deta

Protection from weapons of mass destruction in AFVs

Anti-radiation material usage in Armoured Fighting Vehicles. The penetrating radiation of a nuclear explosion consists of 2 things, a stream of neutrons and gamma radiation, which both pose danger to vehicle crews. One of the countermeasures against such threats is the usage of steel in armour. That is why streams of neutrons (a portion of which outside of the tank's armour exceeds the level of gamma radiation almost by 2-3 factors) pose the main danger when penetrating the tank's main armour. To prevent high-level doses of neutron radiation, the best solution is to use materials that can be enriched or are rich in hydrogen.  Anti-radiation material in the form of additional shielding can primarily be mounted on the amour itself, which needs to have certain abilities to be used in the long run. The main factors are, being able to withstand high temperatures either from direct fire or combustible liquids and deactivating liquids against materials covered in radiation. Additional

Soviet (Hard-kill) APS development

Image
  The development of an Active Protection System in the Soviet Union dates back to the 2nd half of the 1950s.  The creation of the first operational prototype which included the usage of an active method of protection was started in 1958 within the "Дикобраз" - "Porcupine" APS framework.  The basic principle of operation of this APS consisted of covering the probable direction of attack against ATGM. This was achieved by separating the system into different sectors and each sector was protected by a launcher that fired a counter-projectile at an incoming threat.  The development of the next APS prototype, which showed the fundamental possibility of detecting an incoming chemical projectile and countering it at a distance of 1000-1500 meters relative to the tank equipping such APS, was started in the 1960s. The APS was called "Веер" - "Fan", development was carried out by NIIStali together with NIIETI.  The system was made out of 15-20 protective
