The Research Engineering Institute (NIIII) is working on adapting the new Zagon-2 anti-submarine bomb for the Mi-14 helicopter, Sergei Rusakov, general director of the Tekhmash concern, told RIA Novosti.
The Institute has created the Zagon-2 adjustable anti-submarine bomb. It is intended for use from Ka-28 helicopters, but work is currently underway to use these bombs on other types of aircraft. In particular, on the Mi-14,” said Rusakov.
After the release, the 120-kilogram Zagon-2 descends into the sea by parachute. Having reached the surface, the bomb drops its dome, turns on the sonar guidance equipment and rushes towards the submarine. When hitting the submarine's hull, the high-explosive warhead is detonated. The bomb's power is 35 kilograms of TNT.
The one and a half meter ammunition is capable of detecting submarines at a distance of up to 450 meters and hitting them at a depth of up to 600 m. In addition to helicopters, the bomb can be used by Il-38 and Tu-142M anti-submarine aircraft.
Earlier it was reported that the Russian Ministry of Defense is considering the possibility of resuming production of the Mi-14 anti-submarine helicopter, nicknamed the “submarine killer” for its capabilities. The Mi-14 entered service in 1976. The machine was created on the basis of the Mi-8, but after testing and modifications, the result was actually a new amphibious helicopter with more powerful engines and wide combat capabilities.
To ensure buoyancy, the lower part of the fuselage is sealed with inflatable floats on the sides for better stability. The tail rotor was moved to the other side, which increased its efficiency. The Mi-14 is equipped with a 4-post retractable landing gear, a lowered sonar station, a magnetic detector and other special equipment. Torpedoes and bombs can be mounted both in the internal weapons compartment and on an external sling. Total weight combat load is two tons. The arsenal of weapons also included the 8F59 nuclear depth bomb, which was guaranteed to destroy submarines within a kilometer radius.
Since the vehicle’s carrying capacity did not allow it to simultaneously carry means of detecting and destroying enemy submarines, the Mi-14s operated in pairs: one helicopter searched for the submarine, the second attacked it. The vehicle received the nickname “submarine killer” in the late 80s, after it detected and hit a NATO submarine, probably an American one, in Soviet territorial waters. In 1996, under strong pressure from the United States, the Mi-14s were withdrawn from service.
A certain number of vehicles continue to be used by civilian structures and the Ministry of Emergency Situations. The project to resume production of the Mi-14 was presented at the St. Petersburg Naval Show in 2015. It is expected that production of the deeply modernized aircraft will continue at the Kazan Helicopter Plant.
No matter how the United States and its allies try to intimidate Russia with a demonstration of weapons and force, this does not lead to anything significant. For every poison there is an antidote. The Americans are deploying their missiles in Europe, and Russia is deploying similar systems on the western borders of the state.
Americans boast about their creation the latest weapons, which supposedly has no competitors. There is a problem. Our opponents love advertising shows.
However, Russian scientists from the OA Research Institute, in once again, destroyed the hopes of Americans. This time, domestic engineers have developed an adjustable naval aerial bomb, which is designed to destroy submarines enemy at depths of up to 600 meters. This is a significant breakthrough in the field of anti-submarine aircraft weapons. Basically, submarines become inconspicuous when they dive to great depths, where it is very problematic for all available ammunition and search equipment to effectively destroy targets.
To detect a boat hiding in the depths of the sea, aircraft must know in advance the characteristics of the water in the search area, as well as its depth and density. After that, fly for hours over the search site, listening to signals from floating buoys that were placed in advance. Such a search takes a lot of money and a lot of time.
In order to reduce costs and increase the effectiveness of aviation anti-submarine systems, the Zagon-2E anti-submarine adjustable aerial bomb was created. As the creators of the new ammunition say, their creation is capable of detecting and destroying a submarine that is in any underwater position: at periscope depth, and lying on the ground. It is practically impossible to hide from her.
In general, anti-submarine aircraft are considered the most dangerous enemy, against which there are not always ways to defend.
A new development aerial bombs essentially perform the functions of anti-submarine aircraft.
"Zagon-2E" is an adjustable airborne anti-submarine bomb. It is dropped from an airplane or helicopter. When separated from aircraft She does not fly to the water freely, but descends by parachute. During the descent, the incoming air flow acting on the ammunition inflates the floats, which are located on its body.
Error, group does not exist! Check your syntax! (ID: 1)
After splashdown on the water surface, thanks to the floats, the bomb stays on the surface for a certain time. Due to the closure detailed information exact data is unknown.
From the data presented by the engineers, a notable feature of Corral 2 is its noiselessness and ability to remain afloat until it identifies the required target. The search for underwater targets is carried out using an acoustic homing head. The acoustic station penetrates the depths of the sea using the principle of radar. In other words, it emits a signal, and if it finds an underwater object, it is reflected from it and received by the guidance head.
So, being on the surface, “Zagon-2” arranges a kind of ambush on the square. Having received information about the underwater target, the bomb begins to aim at it. Having no engines aircraft the lesions are almost silent. Guidance is carried out under the weight of its own weight at a very high speed, which is 18 m/s. One can imagine what a surprise it would be for the enemy, in the literal sense of the word, for a bomb to fall on his head.
Such properties make a bomb much more dangerous than torpedoes or missiles. The Zagon-2 warhead is a cumulative high-explosive, and in TNT equivalent it is 35 kg. This is enough to destroy a submarine with one bomb. The ammunition has an electromechanical fuse. The shelf life of the device is 10 years.
And if the target could not be detected at the given time, what then? In this case, a self-destruction system is provided.
Accordingly, the question may arise about how protected the bomb body is from penetration. sea water. It is absolutely sealed, since all components of this ammunition are tested in pressure chambers, the pressure in which reaches 400 atmospheres. And each bomb is subjected to this test separately.
The versatility of the ammunition lies in the fact that it can be used both from long-range aircraft anti-submarine aviation– Il-38, Tu-142m, and Ka-27pl helicopters. At the same time, climatic conditions do not matter; Zagon-2 can be used in all places of the World Ocean.

A smart anti-submarine bomb silently makes holes in the hulls of strategic missile carriers
The Research Engineering Institute (part of the Rostec concern), located in Balashikha near Moscow, has begun serial production of the Zagon-2 adjustable anti-submarine aerial bomb. It is a deep modernization of the Zagon-1 bomb, which entered service in 1994.
The Zagon-1 adjustable bomb became a new type of anti-submarine ammunition for its time, having acquired qualitatively different properties. First of all, this relates to secrecy. The bomb uses a gravitational method to approach the target without creating any noise that could be detected by the sonar systems of the attacked boat.
That is, the “Zagon” is devoid of the disadvantage inherent in torpedoes. And at the same time, it has the advantages of a torpedo - it is independently aimed at the target using an acoustic homing head (GOS).
Bombs of this type are equipped with anti-submarine aircraft and helicopters - Il-38, Tu-142ME, Ka-28. When a bomb is lowered by parachute, the float is inflated by the oncoming air flow. On it, the bomb remains on the surface of the sea for some time, up to 4 minutes, after splashdown. In this case, the search mode for the target seeker is activated. It is allowed to use a bomb when the sea state is up to 6 points.
Having found the target, the bomb begins to sink at high speed. Moreover, the dive may not necessarily be vertical.
The increased effectiveness of the new bomb can be seen by comparing tactical and technical characteristics"Zagona-1" and "Zagona-2".
Maximum diving depth, m: 600 - 600
Vertical immersion speed, m/s: 16.2 - 18.0
Maximum immersion angle, degrees: 60 - n/a
Target detection radius, m: 120 - 450
Length, mm: 1300 - 1500
Diameter, mm: 210 - 232
Weight, kg: 94 - 120
Mass of explosive, kg: 19 - 35.
The Zagon-2 bomb is equipped with an electromechanical fuse. The impact on the submarine, which guarantees penetration of the hull, is cumulative.
If an anti-submarine aircraft or a Navy helicopter detects an enemy submarine, a massive bombing attack is carried out. About 6-10 “Penns” are reset. Strictly speaking, they are not completely invisible to the submarine's sonars, since the Zagona seeker carries out active sonar scanning. That is, it works like a radar, emitting acoustic waves and receiving reflected ones. But before the attack, when the exact direction to the target is selected, the scanning is turned off and the bomb begins to dive.
It must also be said that a parachute is used not only to reduce the impact of a bomb equipped with sophisticated electronics on the water. The parachute allows you to reduce the aiming angle, since after its deployment the bomb flies almost vertically. And this leads to an increase in bombing accuracy by high speeds aircraft. As for the word “adjustable,” it has a completely different meaning than the one embedded in the concept of an “adjustable aircraft bomb” (KAB). Correction of the movement of the “Pen” is carried out not in the air, but under water.
Background
Naval aviation appeared before the First World War. But almost until the mid-30s, airplanes, balloons and airships of the Navy and Navy of a number of countries were used exclusively to search for submarines. And they were hit surface ships depth charges, which for quite a long time differed little from ordinary barrels filled with explosives.
However, the first aerial bombs, which appeared shortly before World War II, did not make a big difference in the fight against submarines. In 1940, the Soviet Union adopted the PLAB-100 bomb (anti-submarine bomb) weighing 100 kg with 70 kg of explosive. The bomb was uncorrectable. Having descended by parachute, it immediately began diving and exploded at a given depth. PLAB-100 had low efficiency. In this connection, the pilots preferred to use conventional high-explosive bombs, catching boats that had risen to periscope depth. Before the war, there were 13.5 thousand in warehouses. During the war, only 3.7 thousand were used. Of these, 1.1 thousand were used for other purposes.
Only in the mid-60s did two new anti-submarine bombs appear - PLAB-50 (cluster) and PLAB-250−120 - which became a step forward, although not a very big one. They were equipped with induction fuses, which made the moment of detonation more successful. Moreover, even a sonar fuse was installed. However, these bombs were also uncorrectable, “free-sinking”, everything depended on how close the bomb would fall from the boat.
This, in fact, is all the bomb armament that the naval aviation of the Russian Navy had until 1994, when Zagon-1 was put into service. And when they started talking about anti-submarine bombs seriously.
Until this time, the emphasis was on anti-submarine aircraft torpedoes (PLAT), which began to arrive in naval aviation in 1962. The first such torpedo - AT-1 - turned out to be many times more effective than “free-sinking” bombs. It was capable of hitting boats at depths of up to 200 meters and speeds of up to 25 knots. The weight of the explosive was 70 kilograms. This was quite enough, since the detonation when the induction fuse was triggered occurred at a distance of up to 5 meters from the submarine’s hull. The AT-1's range was 5000 m.
But the main thing is that the AT-1 could independently search for a boat using both active and passive sonars, and, having found it, attack. The search for the target was carried out while the torpedo moved in a spiral with a radius of 60-70 meters. If the torpedo passed the boat further than 6 meters, then the new search for more accurate targeting. After the control time had expired, the “lost” torpedo self-destructed.
In the mid-60s, the AT-2 torpedo appeared. In it, the volume of explosives, as well as the range, have almost doubled. The maximum depth of damage reached 400 meters. The speed when searching for the target was 23 knots, and at the time of the attack - 40 knots. Various modifications of this effective torpedo were produced until the early 80s.
However, in the early 60s, when the military was euphoric from the unlimited possibilities provided by the nuclear chain reaction and uncontrolled thermonuclear fusion, an anti-submarine bomb appeared that did not require precise bombing. First in the USA, since the Americans were the first to create a uranium and then a plutonium bomb. The anti-submarine free-fall ammunition was named Mk.90 Betty.
Serial production of "Betty" began in 1955. Four years later, a plane carrying a bomb crashed into the ocean, and the search for the bomb yielded no results. In 1960, the United States began producing a lightweight bomb, since one “Betty” could destroy not only a pair of Soviet submarines, but also a pair of American ones located at a considerable distance. The new bomb was called "Lulu".
The Soviet Union responded symmetrically in 1963 by establishing production of similar ammunition. The first Soviet nuclear anti-submarine bomb was called 5F48 "Skalp". And soon the 8F59 appeared, the carrier of which was a modified version of the Ka-25 helicopter.
In conclusion, it must be said that aircraft anti-submarine weapons, having gone through a couple of turns of their development, have now to some extent returned to their original point, when there were only “free-sinking” bombs. Not technically, of course, but conceptually. "Zagon-2" is a fairly formidable and effective means of fighting against submarines. And it has a significant superiority compared to aircraft torpedoes. Bombs are much simpler in design, more technologically advanced and much cheaper. After all, in the Soviet Union, money spent on defense was not counted. Now every product, including those of defense importance, has its own price.

Concern "Tekhmash" of the State Corporation Rostec presented at the International Naval Show the anti-submarine adjustable aerial bomb "Zagon-2E", developed on the basis of the Scientific Research Institute (Balashikha). The peculiarity of the bomb is its ability to “hover” above the surface of the water for up to four minutes.
On the first day of the exhibition special attention Participants were attracted by the exhibit “Zagon-2E”. The bomb is designed to destroy submarines (submarines) located in surface, periscope, underwater (up to 600 m) positions, and submarines on the ground in shallow and deep-water areas of the sea. The target detection range is up to 450 m.
The developers managed to increase the effectiveness of the destruction of Zagon-2E by almost three times. At the same time, in comparison with the Zagon-1 aerial bomb, the cost of completing a combat mission has decreased three times.
Today Zagon-2E has no analogues.

PHOTO REPORT: ANTI-SUBARINE ADJUSTABLE AIRCRAFT BOMB “ZAGON-2E” AT IMDS-2017 
During the period June 28 – July 2, 2017, the Research Engineering Institute (JSC NIII) took part in the VIII International Naval Show in St. Petersburg. The exposition of JSC "NIIII" was presented at the collective stand of JSC "NPK "Tekhmash" and the greatest interest of specialists was attracted by the anti-submarine guided bomb (KAB PL) "Zagon-2E".
The aerial bomb was studied with photo and video recording by foreign Navy specialists, arms procurement managers, media representatives from Sweden, Holland, Italy, Belgium, Germany, India, Pakistan, Korea, Egypt, the United Arab Emirates, Argentina, Iran and other countries. Availability professional translator allowed the stand staff to conduct an active dialogue with representatives of the above states, supplementing it with the presentation of a video film about the conditions for using the KAB PL “Zagon-2E”. There is confidence that in the near future JSC Rosoboronexport will begin to receive requests for an aerial bomb developed by the institute.
Two points became an interesting feature during the entire exhibition period. The first is the absence of Chinese representatives among the guests at the stand, while at previous exhibitions specialists from the Middle Kingdom showed great attention to Zagon-2E. And secondly, representatives of Iran came to the stand for 3 days in a row. First, two people, the next day four, and on the 3rd day – 6 people. And every time they asked for a video and promotional materials. Promising interest!
KAB PL "Zagon-2E" is designed to destroy submarines (submarines) located in surface, periscope, underwater (up to 600 m) positions, and submarines on the ground in shallow and deep-water areas of the sea.
The air bomb is unified for use from anti-submarine aircraft (Il-38, Tu-142M) and helicopters (Ka-28) in all areas of the World Ocean.
