Video of the explosion of Kuzka's mother, the most powerful bomb in history, has been declassified

In 1959, at the exhibition at VDNKh “US Industrial Products,” Secretary General Nikita Khrushchev and then US Vice President (he would become president 10 years later) Richard Nixon argued about the advantages of capitalism and socialism. This debate was called the kitchen debate because the exhibition featured what was then called a “typical American home,” including numerous examples of kitchen appliances.

Politicians argued about many things, but the exhibits themselves spoke of the technical superiority of the Americans. And then Nikita Sergeevich, getting excited, said: “The USSR will soon catch up and surpass the USA in terms of living standards. And he added: “We’ll show you Kuzka’s mother!”

“Kuzka’s mother,” which the USSR would show to the United States, then transformed into a threat.

“They really thought it was a new rocket. Because we were making the so-called “Tsar Bomb” of a thousand megatons, which was supposed to blow up half of the globe. And apparently, this is “Kuzka’s mother” - they decided that this was a new weapon. Therefore, the task was even given: to find out about Kuzka’s mother,” recalls the writer, grandson of the USSR Minister of Trade, who was at this exhibition, Alexander Struyev.

The “Tsar Bomba,” which appeared in the USSR only two years later, was called “Kuzka’s Mother” by the Americans.

The most powerful bomb in the world in the VNIIEF museum

AN602 (aka “Tsar Bomb”) is a thermonuclear aerial bomb developed in the USSR in 1956–1961. a group of nuclear physicists led by Academician of the USSR Academy of Sciences Igor Kurchatov. The Tsar Bomba became the most powerful explosive device manufactured in the history of mankind. The bomb is included in the Guinness Book of Records as the most powerful thermonuclear device tested.

The bomb was tested on October 30, 1961. The Tsar Bomb was dropped from a Tu-95B aircraft at the Sukhoi Nos nuclear test site on the island of Novaya Zemlya. This is exactly what the 40-minute secret film published by Rosatom until August 2022 talks about.

The explosion of the most powerful bomb in history.

The explosion of AN602 showed results that impressed even its developers:

— The radius of the fireball of the explosion was approximately 4.6 kilometers, the “nuclear mushroom” of the explosion rose to a height of 67 kilometers. — Light radiation could cause third-degree burns at a distance of up to 100 kilometers. — The seismic wave resulting from the explosion circled the globe three times. “Witnesses felt the impact and were able to describe the explosion at a distance of a thousand kilometers from its center. “Ionization of the atmosphere caused radio interference even hundreds of kilometers from the test site for about 40 minutes.

Explosion of the Tsar Bomba on Novaya Zemlya.

The film is interesting even simply for its style - Soviet scientific and educational cinema. They don't make things like that now. The film shows all stages of bomb testing - from the assembly shop to detonation. All this with narrated text and inspiring music.

By the time of this writing, the video had collected more than 1.8 million views.

How do rocket launches work?

The 2P24 launcher simultaneously performed several tasks - transported missiles to the combat duty point, guided and launched missiles at detected or tracked targets. It could simultaneously transport 2 missiles absolutely ready to hit targets. During start-up, the crew of the machine is inside the SPU.

The missiles were on a boom equipped with hydraulic cylinders, which are responsible for changing the launch angle. The boom itself was part of a support beam, which was fastened to the installation itself by means of cylindrical hinges. When transporting the missiles, they were reinforced with the help of special supports, which were also located on the boom.

And when they get to the infantry school, they shoot at at least 350m

No, in the “infantry school” they don’t shoot further than 300 meters, this is a fact and there is no need to make up your own inventions here.
Not everyone, but only selected fighters, are trained in shooting at a distance of over 300 m, up to 600 m no more (!), in a special SDM (infantry sniper) course. At the same time, it would never occur to anyone to use a standard infantry rifle with open sights there - they shoot from numerous specially equipped modifications of the M16 (Mk12 SPR, SAM-R, SDM-R) or SVD analogs converted from the decommissioned M14 (M39, DMR) .

Fire training for US Army personnel.

Fire training from an automatic rifle in the US Army is a continuous process, including the following stages: - initial fire training (BRM - Basic Rifle Marksmanship); - advanced fire training (ARM - Advanced Rifle Marsmanship); — familiarization with the skills of firing in combat conditions (CFF - Combat Familiarization Fire);

Military personnel who show the highest results in individual fire training during advanced fire training and training in firing in combat conditions are sent to train in the course “Shooting as part of a training (tactical) unit” (SDM - Squad Designated Marksman's course). Mastering the corresponding program involves firing at targets at a distance of 300-600 m.

Otherwise, why would the M-16 and M-4 have a ring rear sight? And even tuned to as much as 800 meters?

For targeted shooting from an open sight up to a maximum of 400 m, nothing more.
Division "800 m." this is an atavism. Quote, Makc

During an intense battle with frequent changes of location, naturally, it will rarely be possible to aim for a long time

…as the experience of hot spots clearly demonstrates.
American Colonel David Hackworth testifies: “In a sudden collision with the enemy, our soldiers, firing from M-16 rifles, overwhelmingly missed a completely visible and motionless target. Moreover, it did not matter whether the shooting was carried out on the move or from an ambush, the results were almost the same: five misses for six shots. There are hundreds of such cases. The number of misses significantly exceeded the number of hits, despite the fact that the shooting was usually carried out from fifteen meters or less, and in some cases from less than three meters. The shot on the spot became a legend. As for the dependence of the effectiveness of fire on range, in the analysis of six large and approximately 50 small operations there is not a single evidence of when at least one guerrilla or soldier of the armed forces of North Vietnam was killed when firing from M-16 rifles from a distance of more than 60 meters " The Vietnamese experience is fully confirmed by the Afghan one. This is how a GRU special forces officer describes one battle in Afghanistan. On March 16, 1987, a group of nine militants was destroyed. They were fired at, it would seem, in ideal conditions - from top to bottom at an angle of 25-30 degrees from a distance of 50-60 meters. Success factors: moonlit night, the presence of night vision devices and extremely weak enemy opposition due to the surprise of the actions of special forces soldiers. Despite this, each of the scouts spent at least two or three magazines, that is, about nine hundred rounds of ammunition per group, which amounted to a hundred for each “Mujahideen” killed. Characteristically, the battle was not fought by recruits, but by well-trained soldiers; the group included four officers.

I would like to emphasize that both experts spoke about trained fighters.

Specifications

Having analyzed the performance of all vehicles belonging to the complex, we can draw a conclusion regarding the combat effectiveness of the Krug air defense system:

The maximum speed is 50 km.
The range of the complex (without refueling) is 300 km.
Response time is less than one minute.
Deployment of an air defense system takes less than 5 minutes.
The range of destruction of an air target is from 11 to 43 km, at an altitude of 3-23.5 km.
The flight speed of the affected objects is no more than 800 m/s.

But exact data regarding the combat effectiveness of the Krug complex is impossible. The combat use of the equipment has not been declassified to this day. The only thing known is that these air defense systems were used during the Vietnam War and during the improvement of the “Barlev air line” in Egypt.

How to properly put on handcuffs for a 4th grade security guard exam

The person being tested is 1.5 meters opposite the dummy. The rubber stick is suspended on a belt. At the inspector’s command: “Start the exercise!” the person being tested removes the rubber stick from the suspension and strikes the dummy (at least six) in various areas allowed for impact with the rubber stick. After this, the person being tested reports: “I have finished the exercise.”

The employee being inspected is located near the table with protective vests of class 1 and 5. At the command of the supervisor, the inspected employee puts on a protective vest of the specified class and reports: “The protective vest of class 1 (or class 5) is on.” The exercise time is 20 seconds.

Practical part for 4th grade

The employee being inspected is located near the table with protective vests of class 1 and 5. At the command of the manager, “Put on a protective vest of class 1 (or 5),” the inspected employee puts on a protective vest of the specified class and reports: “I have finished the exercise.”

The worker being tested is 1.5 meters opposite the dummy. The handcuffs are on the belt in a case.

At the supervisor’s command “Place handcuffs in front (or behind),” the employee being inspected takes the handcuffs out of the case, approaches the mannequin and puts on handcuffs depending on the task assigned by the supervisor (front or rear). After that he reports: “The handcuffs are on.” Execution time 20 seconds.

4th grade security guard

In addition, exam cards for grade 4 security guards contain questions on current legislation. As part of testing, it is necessary to find out how ready a citizen is to perform the duties of a security guard and apply laws in the course of his activities.

It must be remembered that qualification for category 4 involves the use only of a rubber baton (in extreme cases) or handcuffs, so the questions for the exam by category are similar, but the answers are different. It is necessary to respond due to the given powers to use special means.

Questions of the qualification exam (Practical exercises of the qualification exam) for private security guards of the 4th category

Positive result: Delivering at least six blows with a rubber stick on the dummy, without touching parts that conventionally correspond to areas of the human body that are prohibited from using rubber sticks on them, within the prescribed time.

SAM S-25 Berkut. Range and altitude of damage. Rockets

S-25 "Berkut". In the late 1940s and early 1950s, the Soviet Union began one of the most complex and expensive programs of the early Cold War, second only to its nuclear weapons program. In the face of a threat from the strategic bomber forces of the United States and Great Britain, J.V. Stalin ordered the creation of an air defense missile system controlled by a radar network to repel possible massive air attacks on Moscow. The Moscow system was followed in 1955 by a second program aimed at protecting Leningrad.
