This is how Vietnam turned B-41 anti-tank gun into 'cannon cannon'

B-41 anti-tank guns are getting stronger as Vietnam has autonomously built thermo-drugs, opening the door to developing more powerful thermonuclear weapons.

According to the report on "Successful production of thermo-explosive" on VTV2, recently the Institute of Weapons collaborated with the Institute of Drives and Explosives to successfully study thermo-explosive TNNA-7V for thermo-weapons. powerful.

However, according to the report on the thermo-explosive, it is only used by Vietnam to create a new bullet model for the B-41 anti-tank gun , one of the standard infantry weapons of the Vietnam People's Army. .

With the successful fabrication of the thermo-explosive, the young research group of the Institute of Weapons applied this special type of explosive to the project of manufacturing the pressure-sensitive bullet ammunition for the anti-tank gun B-41. design of Russian model TBG-7V.

Experiencing many times of testing, the SEA-7V has been evaluated to meet the technical requirements of the research group.

In terms of operating principle, the SEA-7V thermo-bullet has the same firing principle as the anti-tank or anti-infantry bullets of the B-41 anti-tank gun, so the gun without modification can still shoot Southeast Asia. -7V.

However, the SEA-7V is equipped with a powerful thermo-warhead and the destructive power is many times superior to that of conventional bullets.

According to the specifications of the SEA-7V introduced by the Institute of Weapons, this thermo-bullet model has the size of 105mm warhead; warhead weighs 4.5kg; 996mm wheelbase.

The effective range of SEA-7V is about 120m and the farthest (with viewfinder) is 500m; The warhead is 120m / s. The impact range of an explosion with the SEA-7V heat bullet can be up to more than 40m2

Challenge to manufacture "Made in Vietnam" heat bullet

Compared to previous types of B-41 anti-tank rockets, a thermo-bullet is a new type of bullet that is effective in various types of targets such as destroying bunkers, underground tunnels, buildings or motorized vehicles. with enemy forces

The heat-resistant bullets themselves for B-41 anti-tank guns (or RPG-7) were only manufactured by the Soviet Union in the late 1980s, most notably TBG-7V.

Currently the technology involved in making thermo-bullet or thermo-weapon is still new in our country because it uses thermo-explosive, this is a new type with different operating mechanism than other types. Previous explosive.

This also poses no small challenge to the topic group of the Weapons Institute when it is necessary to create a type of thermo-explosive to fit inside a bullet weighing just over 4kg but still creating the explosion is equivalent to a large cannon shell with 1.5-2 times more explosive power than TNT.

Through many times of research and testing, testing and taking a lot of time and effort for the thermo-explosive manufacturing project of the Institute of Weapons in collaboration with the Institute of Launching and Explosive Medicine, it was successful in determining the single ingredient fabrication of thermo-explosive TNNA-7V in addition to meeting the requirements of stuffing and fitting for SEA-7V thermocouple bullets.

In addition, the team also developed the casting method of TNNA-7V into a vacuum-sealed bullet body, built a test and acceptance method to evaluate the prestige of thermo-explosive and thermocouple warheads suitable for Existing measuring equipment in the country.

In particular, engineers of the Institute of Weapons have successfully researched the fabrication of thermocouple shells with a new body of seamless casing on both ends, which had never been built on the existing technological lines in the country. .

From the Weapons Institute's success in manufacturing thermo-explosive as well as thermo-bullet bullets for anti-tank guns B-41 has opened up new research directions with the relatively advanced world of heating weapons in the world. current paragraph.

It can be seen that mastering technology in designing, repairing production and effectively exploiting new equipment is the direction of effective research of units under the General Department of Defense Industry.

From defense products with high scientific content will be a premise to open up the next research to better meet the tasks of defense production and combat readiness training in the Vietnam People's Army.
