Archer-type self-propelled gun on a BT tank chassis. Archer is a British Tier V tank destroyer. Equipment for Archer

Archer is a British Tier 5 tank destroyer, added in patch 0.9.5. Another unusual car from a new branch. Distinctive feature- reverse speed, which is almost three times higher than forward speed due to design features

Historical reference

SP 17pdr, Valentine, Mk I, Archer - British anti-tank self-propelled gun from the Second World War, created on the basis of the chassis infantry tank Valentine and equipped with a 17-pounder Ordnance Quick-Firing 17-pounder (76.2 mm) gun.

PT- Self-propelled gun Archer

17 lb. anti-tank gun It was very powerful, as well as very large and heavy, so special equipment would have been needed to move it across the battlefield. In addition, this would make the weapon more effective in defense than in attack.

For these purposes, the chassis of the Valentine tank was chosen - it was ideal for transporting such a bulky weapon. Valentine's corps did not allow the installation of a turret and they decided to install the gun in an armored wheelhouse without a roof. The gun could rotate 11 degrees both left and right. Vertical aiming angles ranged from -7.5 to +15 degrees.

The uniqueness of Archer was that its gun, unlike most other self-propelled guns, was mounted backwards, which gave certain advantages in battle.

The special placement of the gun, combined with a low silhouette, turned the Archer into an excellent ambush tank: the crew could fire a shot and drive to a safe distance.

The first prototype was ready in 1943. It was decided to produce 800 tanks.

Production of Archers began in mid-1943, and the tank was put into operation in October 1944. The Archer was used in combat in Northwestern Europe and Italy. By the end of the war, 655 tanks were produced.

Review

The car was simply created to surprise the enemy. This tank destroyer can be played according to the principle “hard to catch up, easy to escape.” It effectively fires back at the enemy while retreating, and is almost incapable of conducting active offensive operations as part of small groups.

The most effective tactic would be to take a convenient, covert position at the front edge of the offensive and support allied tanks in this direction. Second line tactics will not be as useful, because this vehicle requires significant time and effort to quickly advance and constantly support allied tanks with fire. On the other hand, it is capable of quite effectively holding off advancing enemies thanks to its excellent weapon, one-time damage and high reverse speed.

Advantages

Good stealth
Comfortable weapon
High turning speed
Small scatter from movement within horizontal angles
Wide firing sector
Good review
High armor penetration
Good accuracy
Comfortable gun declination angles

Flaws

To quickly change position you need to turn around
Relatively small ammunition load
Weak armor
Unusual control

Bottom line

The first truly British tank destroyer in the branch, and, undoubtedly, a very interesting and controversial vehicle. On the one hand, low visibility, an excellent weapon, and in almost all respects, on the other hand, poor visibility and a non-standard layout, thanks to which, playing on this machine turns into “one step forward, two steps back”, because in order to drive even just 50 m you have to turn around, and upon arrival at the place you have to turn around again.

In general, the car is quite good, but it depends quite heavily on both the team (zero armor, and the enemy is unlikely to calmly watch your pirouettes, and the car is blind) and on the player’s personal skill (not everyone is good at running backwards to forwards) .

On September 23, a long-awaited event took place in Sweden. The Ministry of Defense Procurement Directorate (Försvarets Materielverk) has accepted the first batch of FH77BW L52 Archer self-propelled howitzers on a wheeled chassis. Four new combat vehicles adopted for service under the name Artillerisystem 08. In about a year, the Swedish military department intends to receive a second batch of self-propelled artillery units consisting of 20 vehicles. In addition, 24 self-propelled guns will be built for Norway in the near future.

The long-awaited delivery of self-propelled guns to the customer turned out to be due to a number of technical problems. In accordance with the first contracts signed during development, Archer self-propelled guns were supposed to join the Swedish armed forces back in 2011. However, during testing of the prototypes, some shortcomings were identified, which took some time to correct. As a result, the first batch, consisting of only four pre-production combat vehicles, was handed over to the customer only in September 2013. In the future, the Swedish army will receive serial equipment.

Separately, it is necessary to note the situation with artillery in the Swedish army, which developed as a result of the failure to deliver the Archer self-propelled guns. Currently, artillery in the Swedish Armed Forces is represented only by the 9th Artillery Regiment, consisting of two divisions. By the end of 2011, due to the exhaustion of their service life, all existing towed 155-mm Bofors FH77B howitzers were written off, which is why the Swedish armed forces were completely deprived of any field artillery. It was initially assumed that the new Archer self-propelled guns would replace towed howitzers, but the problems that accompanied the creation of the self-propelled gun derailed the implementation of these plans, and as a result, the Swedish army did not have any artillery for almost two years.

The preliminary stage of the project took several years. Only in 2003, the Swedish Ministry of Defense signed a contract with Bofors. This document provided for the completion of the project and the subsequent construction of serial self-propelled guns. In 2005, the first prototypes of a promising self-propelled gun were built. Testing of self-propelled guns began after the transformation of the Bofors company into BAE Systems Bofors.

A Volvo A30D with a 6x6 wheel arrangement was chosen as the chassis for the new self-propelled artillery mount. The chassis is equipped with a 340 horsepower diesel engine, which allows the combat vehicle to reach highway speeds of up to 65 km/h. The wheeled chassis is said to be able to move through snow up to one meter deep. If the wheels are damaged, including due to an explosion, the Archer self-propelled gun is capable of continuing to move for some time.

An interesting feature of the Archer self-propelled gun chassis is the architecture used. The A30D has an articulated design that improves maneuverability. At the front of the chassis, above the first axle and up to the articulation unit, is the engine compartment and cockpit. The engine and crew are covered with bulletproof armor corresponding to level 2 of the NATO standard STANAG 4569. The cabin accommodates workplaces for three or four crew members. Depending on the nature of the operation being performed, the crew may have one or two weapons operators. The driver and commander are always present in the crew. On the roof of the cockpit there is space for installing a Protector remote-controlled turret with a machine gun.

All components of the gun are located on the rear module of the articulated chassis. Above the rear axle of the chassis there are mechanisms for lifting and turning the gun turret. The gun is aimed by turning and raising the entire turret. The self-propelled gun mechanisms allow you to aim the gun vertically in the angle range from 0° to +70°. Due to the characteristics of the wheeled chassis, horizontal aiming angles are limited: Archer can fire at targets in the front sector with a width of 150° (75° to the right and left of the axis). To stabilize the vehicle when firing, a double outrigger is used at the rear of the chassis. In the stowed position, the gun module rotates to a neutral position, lowering the howitzer barrel into a special tray covered with covers. The dimensions of the base car required an interesting solution. So, when transferring self-propelled guns to stowed position The gun's recoil devices move the barrel to the rearmost position, which allows it to be placed in the existing tray.

The Archer wheeled self-propelled gun is quite large in size. The maximum length of the combat vehicle exceeds 14 meters, width - 3 meters. Without the use of the Protector turret, the height of the self-propelled gun is 3.3 meters, and after installing this combat module increases by about 60 cm. The combat weight of the Archer self-propelled gun does not exceed 30 tons. The dimensions and weight of the FH77BW L52 self-propelled artillery mount allow it to be transported across railway. In the future, it is planned to use Airbus A400M military transport aircraft for this purpose.

During combat work, the Archer self-propelled gun crew is constantly at their workplaces and does not leave them. All operations are carried out according to commands from control panels. In this regard, all mechanisms of the gun turret operate automatically. The main elements of the turret equipment are the loading mechanisms. According to reports, instead of a single system, the Archer self-propelled gun uses two mechanisms that interact with each other. One of them fires 155mm shells. Mechanized stowage capacity – 21 shells. The second loading system operates with propellant charges supplied in the form of cylindrical blocks with a combustible shell, reminiscent of a charging cap. The Archer self-propelled gun turret stack accommodates 126 blocks with a propellant charge. When using a transport-loading vehicle with a cargo crane, it takes about eight minutes to fully load the ammunition load.

Depending on the task, the crew of the FH77BA L52 Archer self-propelled howitzer can increase or decrease total propellant mixture, changing the number of charges placed in the weapon. At maximum quantity propellant charges, the Archer self-propelled howitzer is capable of sending a projectile to a target at a distance of up to 30 kilometers. The use of active-reactive or guided ammunition increases the firing range to 60 km. The latter is declared for the Excalibur adjustable projectile. The Archer self-propelled gun can fire directly, but in this case the effective firing range does not exceed two kilometers.

The gun's loading mechanisms provide a rate of fire of up to 8-9 rounds per minute. If necessary, the self-propelled gun crew can fire in MRSI mode (the so-called barrage of fire), firing six shots over a short period of time. A salvo of 21 shots (full ammunition) takes no more than three minutes. When developing the Archer self-propelled gun, the need to reduce the time for preparing to fire and leaving a position was taken into account. As a result, the self-propelled gun can carry out some of the preparations for firing while still on the way to the position. Thanks to this, the first shot is fired within 30 seconds after stopping at the desired point on the route. During this time, the outrigger is lowered and the tower is brought into firing position. After completing the fire mission, the crew transfers the combat vehicle to the stowed position and leaves the position. It also takes about 30 seconds to prepare to leave the position.

The FH77BW L52 Archer self-propelled gun is equipped with a modern digital fire control system. Electronic equipment and associated systems allow the crew to carry out all necessary operations without leaving their workplaces. In addition, the automation takes on some of the important actions related to preparation for firing: determining the coordinates of the self-propelled guns, calculating the required pointing angles and firing according to the MRSI algorithm. When using a guided projectile Excalibur or similar, the automation prepares the ammunition for firing.

As already mentioned, the first production Archer self-propelled guns were supposed to be delivered to the troops back in 2011. However, during development, some problems emerged with a number of systems used. It took several years to eliminate the shortcomings, which ultimately led to missed deadlines. Even during testing and development, the first contracts for the supply of serial combat vehicles were signed. In 2008, Sweden ordered eight new self-propelled guns, Norway - one. A few months later, the Scandinavian states decided to jointly finance the project. In accordance with the 2009 contract, BAE Systems Bofors must supply the two countries with 24 self-propelled artillery units.

Negotiations regarding possible export contracts are currently ongoing. The Archer self-propelled gun has attracted the interest of military personnel from Denmark and Canada. These states are negotiating the supply of a certain number of combat vehicles. It is known that Denmark can purchase no more than two dozen self-propelled guns. Until recently, negotiations were ongoing with Croatia. This country was going to buy at least 24 FH77BW L52 self-propelled guns to replace aging Soviet-made equipment. However economic problems did not allow Croatia to purchase Swedish combat vehicles. As a result of lengthy comparisons and negotiations, the Croatian armed forces decided to buy 18 used PzH2000 self-propelled howitzers from Germany. Delivery of the purchased self-propelled guns will begin in 2014.

Combat and operational characteristics make the self-propelled artillery installation FH77BW L52 Archer is a worthy representative of its class military equipment. However, some technical solutions, applied in the project, at one time led to several difficulties. All this could have a negative impact on the reputation of the project. Due to difficulties in developing the Archer self-propelled guns, the Swedish army was left without field artillery for quite a long time, and several months remain before the start of mass deliveries of new self-propelled guns. It should be noted that even before the start of mass production, the Archer self-propelled gun attracted the attention of potential buyers in third countries. It is quite possible that new contracts for the supply of self-propelled guns will be signed in the very near future.

155MM SELF-PROPELLED HOWITZER FH77BW L52 ARCHER (SWEDEN)

155-MM SELF-PROPELLED HOWITZER FH77BW L52 ARCHER (SWEDEN)

08.07.2009
THE CEREMONY FOR ROLLING OUT THE FIRST PROTO MODEL OF THE 155-MM SAU "ARCHER" WAS HELD

Bofors, a division of BAe Systems, held a ceremony to roll out the first prototype of the Archer 155-mm self-propelled artillery mount (SPG), the Swedish Military Purchasing Agency (FMV) reported.

FMV has been searching for a modern self-propelled artillery system to replace the FH-77B towed howitzer since the mid-1990s. During the implementation of the program, several foreign systems were tested, which, based on the evaluation results, were rejected due to high cost or non-compliance with the requirements of the Swedish Armed Forces. As a result, it was decided to independently develop a new 155-mm Archer self-propelled gun on the chassis of the Swedish Volvo A30D all-terrain truck using a modified FH-77B howitzer as an artillery unit.
In November 2008, FMV representatives signed an agreement on the joint development of the 155-mm Archer self-propelled gun with the Organization for logistical support of the Norwegian Armed Forces (FLO). In January 2009, a contract worth $70 million was signed with BAe Systems to complete the development of the Archer self-propelled guns for Swedish and Norwegian aircraft.
The Archer self-propelled gun is a modified FH-77B howitzer mounted on the chassis of a Swedish Volvo A30D off-road truck. The differences between the new 155-mm Archer self-propelled gun and the FH-77B are the barrel length increased by 2 m and the cabin equipped with ballistic protection, as well as the use of the latest technologies for detecting and hitting targets. It is planned that the installation will be able to fire guided high-precision artillery shells with the system satellite guidance"Excalibur". The range of destruction of targets of the Archer self-propelled gun when firing high-precision ammunition should be 50 km, starting speed ammunition - 945 m/s, ammunition - 21 shells. The maximum speed of self-propelled guns on the highway will be 70 km/h, crew - 3-4 people. (commander, driver and 1-2 operators). Deployment time to open fire is 30 seconds. In this case, the crew will control all actions without leaving the cockpit. The cabin protection system against mines and shell fragments will be developed by Akers Coolbrook. The Norwegian Protector combat station will be used as a self-defense system for the self-propelled guns. The self-propelled gun will also be equipped with other reconnaissance, surveillance and target detection systems.
The agreement signed by FMV and FLO contains an option for the supply of 24 Archer self-propelled guns (48 systems in total) to the armed forces of the two countries. The installations intended for delivery to Sweden and Norway will differ from each other.
The demonstrated N1 prototype was manufactured in a configuration intended for delivery to the Swedish Armed Forces. According to the plan, the assembly of the second prototype will be completed in the near future, which will be manufactured in a configuration for the Norwegian Armed Forces.
It is planned that data testing prototypes will be completed in spring 2010. By 2011, the defense departments of Sweden and Norway will decide to begin mass production of the units. Delivery of the Archer self-propelled guns to customers should begin in 2011. Currently, the armed forces of Denmark, Belgium, Malaysia, Qatar and the Czech Republic are also considering the possibility of purchasing new artillery systems.

GUIDED ARTILLERY PROJECTILE "EXCALIBUR" PASSED TESTS

The Excalibur Ib guided artillery projectile (UAS) manufactured by Raytheon has passed field tests. The company's press service reported this.
According to Raytheon, a total of 84 rounds were fired during the test firing. Most of the projectiles had a maximum deviation from the target of 2 m, which is a high figure. During the tests, the positive combat qualities of the ammunition and its compliance with the requirements of the US Department of Defense were also noted.
Shots using UAS were fired from the Swedish self-propelled artillery mount (SAU) Archer and two American howitzers - M109A6 Paladine and LW-155. In 2014, tests of the Excalibur UAS will be carried out, which will show its suitability for mass production.
Based on the firing results, it was found that the projectile exceeded its tactical and technical characteristics (TTX) in a number of indicators. The maximum target engagement range was 50.4 km when fired from the Archer self-propelled gun. When testing the compatibility of the projectile with American artillery systems, a range of 40.54 km was achieved, which also turned out to be greater than the declared characteristics of the ammunition.
The Excalibur-1b version of the UAS is produced by Raytheon and is a further development of the Excalibur-1a-1 and Excalibur-1a-2 ammunition. The caliber of the UAS is 155 m, it is aimed at the target using the GPS satellite navigation system, which ensures high accuracy of destruction.
In addition to the Excalibur-1b version of the UAS, Raytheon is developing an improved navigation system for all projectiles of this class.
Up to now, 640 Excalibur UAS have been fired. The projectile is used for targeted destruction of targets of particular importance. According to recent studies, the use of one Excalibur UAS allows you to save from 10 to 50 conventional shells.

11.12.2013

The Norwegian Ministry of Defense announced the country's government has decided to terminate a joint project with Sweden to develop and purchase the Archer artillery system. According to the representative of the Norwegian Ministry of Defense Birgitte Frisch, the refusal of delivery is due to the delay in the implementation of the project and the self-propelled guns’ non-compliance with a number of new requirements of the Norwegian Armed Forces. Under the terms of the agreement, all 24 self-propelled guns were planned to be delivered by the end of 2013, but as of December 2013, deliveries of self-propelled guns to the Norwegian Armed Forces had not yet begun.
A statement from the Norwegian Ministry of Defense indicated that due to the change in the concept of the Armed Forces, they must be more mobile and act quickly. This implies that Archer self-propelled guns no longer meet the new requirements.
Despite the refusal to purchase self-propelled guns, Norway announced its intention to continue cooperation with Sweden in the field of artillery systems, radar artillery reconnaissance, fire control systems, ammunition, personnel training.
According to B. Frisch, Norway has currently spent 550 million crowns on the Archer self-propelled gun project, including 380 million crowns for development and 170 million crowns for the acquisition of self-propelled guns. In the near future, the parties will hold negotiations to determine further relations. It is possible that penalties will be applied to Norway.

155MM SELF-PROPELLED HOWITZER FH77BW L52 ARCHER

The project to develop a promising self-propelled artillery unit started in 1995. In accordance with the terms of reference, the executing organization had to develop an self-propelled gun armed with a modified FH77B howitzer of 155 mm caliber. The customer demanded to improve the characteristics of the gun by increasing the barrel length. The result of the modernization of the howitzer was the FH77BW modification with a 52-caliber barrel. This is exactly the weapon that was supposed to be used in the new self-propelled gun. In addition, the customer's requirements implied the use of a wheeled chassis.
The preliminary stage of the project took several years. Only in 2003, the Swedish Ministry of Defense signed a contract with Bofors. This document provided for the completion of the project and the subsequent construction of serial self-propelled guns. In 2005, the first prototypes of a promising self-propelled gun were built. Testing of self-propelled guns began after the transformation of the Bofors company into BAE Systems Bofors.
A Volvo A30D with a 6x6 wheel arrangement was chosen as the chassis for the new self-propelled artillery mount. The chassis is equipped with a 340 horsepower diesel engine, which allows the combat vehicle to reach highway speeds of up to 65 km/h. The wheeled chassis is said to be able to move through snow up to one meter deep. If the wheels are damaged, including due to an explosion, the Archer self-propelled gun is capable of continuing to move for some time.
The Archer self-propelled gun is a modified FH-77 B05 52 howitzer mounted on the chassis of an improved Volvo A30D all-terrain truck with a 6x6 wheel arrangement. The differences between the new 155-mm Archer self-propelled gun and the 77B are the barrel length increased by 2 m and an armored cabin that provides protection for a crew of three. The installation will be able to fire 155 mm ammunition various types, incl. controlled high-precision with the Excalibur satellite guidance system. The firing range of the Archer self-propelled gun with conventional ammunition is more than 40 km, with improved ammunition – up to 50 km.

The crew is accommodated in an armored cabin, which is equipped with a system of protection against weapons of mass destruction. Remote control loading, guidance and firing systems are carried out from the cockpit. The cabin can accommodate four people, provides blast protection and is equipped with a number of visibility reduction features. To increase platform stability when shooting, a hydraulic outrigger is lowered at the rear of the vehicle. During the tests, more than 700 rounds of 155 mm active-reactive missiles were already fired cumulative shells HEER long-range projectiles, HE77 shaped charge rounds and TR 54/77 point charge training rounds.

Uniflex 2 modular charges, FH77 B L39 cap charges and Bofor 4-7,8 and 9 charges were used. The maximum firing range depends on the shell-charge combination, but is generally 40 km when firing standard shells and 60 km when firing 155 mm shells XM982 Excalibur. The system contains 40 shells, 20 of which are located in the gun’s automatic magazine. The system uses both cartridge and modular projectiles with automatic ramming. The day-night sight allows direct fire from a distance of 2,000 meters. In addition to standard ammunition, the FH77 BW L52 will be able to fire long-range XM982 Excalibur projectiles, which are currently being produced in limited quantities for the US and Swedish armies.
On September 23, 2013, the Swedish Armed Forces received the first batch of four 155-mm FH-77 BW L52 Archer self-propelled guns (6x6), manufactured by BAe Systems. In the Swedish Armed Forces, a new self-propelled unit will replace the outdated 155-mm towed howitzer FH-77B. The Swedish Ministry of Defense intends to carry out further purchases of the Archer self-propelled guns independently.
The Archer self-propelled guns intended for the Norwegian Armed Forces, as one of the options, can be offered at a reduced cost to the Danish Armed Forces, which are currently holding a tender for the supply of self-propelled artillery systems.

The combat weight of the Archer self-propelled gun does not exceed 30 tons. The dimensions and weight of the FH77BW L52 self-propelled artillery mount allow it to be transported by rail. In the future, it is planned to use Airbus A400M military transport aircraft for this purpose.

Depending on the task at hand, the crew of the FH77BA L52 Archer self-propelled howitzer can increase or decrease the total amount of propellant mixture by changing the number of charges placed in the gun. With the maximum number of propellant charges, the Archer self-propelled howitzer is capable of sending a projectile to a target at a distance of up to 30 kilometers. The use of active-reactive or guided ammunition increases the firing range to 60 km. The latter is declared for the Excalibur adjustable projectile.

Currently, there are the following international criteria for preliminary (that is, applied before the model begins to participate in hostilities) assessment of any type of weapon:

Cost - the cost of the project itself;
Rate of Fire - rate of fire;
Accuracy - shooting accuracy;
Range - firing range;
Intelligence is an indicator of the integration of this type of weapon with modern ones intelligence systems.

Note that the developers do not hide these criteria, and moreover, oddly enough, they do not try to overestimate them, for which there is a clear explanation. In view of the norms of professional and business ethics, the impossibility of confirming the developed system during trial operation of the declared characteristics threatens not only loud scandal, but is fraught with the cessation of the existence of the company itself. It is for these reasons that the indicators of the weapon being developed are not overestimated, but, on the contrary, underestimated.

First of all, you should understand why or why Russia began developing its own artillery system “ new generation" in 2006 year? The thing is that in 2004 and 2005, at IDEX 2004 and IDEX 2005, the Swedish development was shown as promising for adoption into service of a 155-mm self-propelled gun, which was designated FH77BW L52 (Bofors self-propelled howitzer of 1977 with a 52-caliber barrel length), later called Archer (or " Archer"). The development of this self-propelled howitzer began in 1995. At that time, the Russian armed forces had no time to develop their own self-propelled guns.

In 2003, a contract was signed between the Swedish Armed Forces and the Bofors company (now BAE Systems Bofors) for the subsequent development of the self-propelled guns. In 2004, the first two prototypes of the self-propelled guns were shown. Trial military operation of the first two 155-mm Archer self-propelled howitzers began in 2005, and in 2006 the contract was extended for the subsequent development and improvement of the self-propelled gun development program. In September 2008, the Swedish government finally approved the development and purchase of 48 Archer self-propelled artillery systems for its Armed Forces.

At the same time, Sweden was not going to rush into final adoption of this artillery system (since the FH77BW L52 Archer self-propelled gun itself is not just a self-propelled howitzer). In the period from 2007 to 2015 (that is, a full 8 years), experimental military operation of this self-propelled artillery installation continued. And as a result, the first battery of self-propelled guns FH77BW L52 Archer officially began to be listed in the Swedish Armed Forces only on February 1, 2016.

In accordance with the five points of the preliminary assessment, first let's look at what the FH77BW L52 Archer 155 mm self-propelled howitzer project was:

Cost - or the cost of the project itself - from 1995 until it was put into service in 2016 - $450,000,000.
Rate of Fire - rate of fire - 8-9 rounds per minute, in multiple rounds of simultaneous impact (MRSI) mode - 6 rounds.
Accuracy - shooting accuracy - circular probable deviation (CEP) in accordance with NATO requirements - up to 120 meters for unguided projectiles and from 25 to 3 meters for guided projectiles.
Range - firing range - from 30 to 50 kilometers for conventional and active-missile projectiles and up to 60 km when firing a guided projectile M982 Excalibur.
Intelligence - an indicator of the integration of this type of weapon with modern reconnaissance systems - is integrated into a single automated fire control system AFATDS (also known as modern system NATO field artillery data).

By and large, the FH77BW L52 Archer self-propelled gun is not a deep modernization of the FH77 towed gun, but a completely new gun, which is currently the only self-propelled howitzer in the world adopted for service, with a completely uninhabited fighting compartment.

The development of a self-propelled gun, and not a howitzer (this will be proven in this article), 2S35 in Russia began after representatives of the Russian military-industrial complex turned their attention to the promising Archer self-propelled howitzer at IDEX 2004. At the same exhibition Russian representatives We also looked at the Swedish 120-mm AMOS progressive mortar system.

As a result, since 2005, the Russian Federation has launched the creation of its own artillery systems, in accordance with the tradition that existed back in the USSR, to respond by creating a supposed analogue model in response to the emergence of any new type of weapon in NATO.

Now, for the sake of understanding, let’s pause a little and turn our attention to the representative of the customer’s body, which is an artillery officer Russian army. We will make one small comment that will help to clearly characterize his preparation.

At the Artillery Academy (St. Petersburg), from 2000 to the present, the list of training subjects does not include such a discipline as ballistics. Ballistics is present to a limited extent in such a subject as “ Shooting theory and shot control" Thus, Russian officers are the only artillerymen in the world who do not know their main subject. Among other things, this circumstance clearly demonstrates the lack of trained personnel in the existing paradigm of Putin’s state regime.

What does the artillery system and personnel training have to do with it? Let's be clear.

Any interested reader can look at a completely open version of Russian Wikipedia and find in it comparison table tactical and technical characteristics(TTX) of the 2S35 self-propelled gun with foreign analogues. For a better understanding, let's take the combat rate of fire subsection as an example.

The creators of the 2S35 system claim that it has the above figure of 11-16 rounds per minute. Such information could only be written by people who do not understand the essence of ballistics, especially the phenomenon after a shot as barrel swinging. The phenomenon of barrel swinging occurs during a short transition period between the phases of internal and external ballistics, when the projectile leaves the gun barrel.

It is this short period of time, and the associated phenomena during a shot, that intermediate ballistics studies. Such a section of ballistics as “ intermediate ballistics"was not considered in Russia due to the lack of ballistics as a science in general.

It is this section that answers the question about the maximum technically possible limit of the rate of fire of any howitzer or cannon artillery piece with a barrel length exceeding 11 calibers, while maintaining certain standards of accuracy of the shooting itself. This technical limit is 10 rounds per minute. Thus, the next shot occurs after 6 seconds precisely so that the vibrations of the gun barrel associated with the previous shot stop.

In fact, no manufacturer is in a hurry to produce an artillery piece even with 10 rounds per minute. An indicator of 8-9 rounds per minute is quite sufficient figures when firing from a modern artillery gun. Therefore, the emphasis on the high rate of fire of a gun in considering its characteristics today is the first indicator of a lack of personnel and understanding of artillery.

Let's move on to the issue of novelty and modernity of the Russian self-propelled gun using the example of its barrel. Creators self-propelled gun 2S35 states that the barrel of the 2A88 gun is new, without saying anything at all about its creation.

But we can do a little research ourselves. If you compare images of the 2S35 and its barrel with the Soviet 2A36 gun, you will notice striking similarities in detail, namely in the length of the barrel and the type of muzzle brake installed. At the same time, the creators a fundamentally new artillery gun“do not explain at all the moment how suddenly the barrel of a 2A36 cannon, after installing a receiver on it (a device for reducing gas contamination in the fighting compartment), can become a howitzer barrel? How did this become technically possible?

If the barrel was originally created in the USSR as a cannon barrel, then the same barrel cannot be howitzer by default.
Therefore, we can conclude that this is not a 2S35 self-propelled howitzer, but just a modernized analogue of the Soviet 2A36 cannon. To be even more precise - its self-propelled analogue 2S5.

The problems don't end there. The service life (that is, survivability) of the barrel of the Soviet 2A36 gun is no more than 650 shots, after which the barrel must be changed. Otherwise, its ballistic characteristics will not correspond to those described in the shooting tables, even when appropriate corrections are introduced.

Moreover, the Soviet 152-mm 2A36 cannon and its self-propelled analogue 2S5 were not designed at all to fire traditional (HE) shells as the main ones. The main purpose of the 2A36 and 2S5 is to fire a 152-mm 3VB6 nuclear projectile. For firing a nuclear projectile, the ballistic dispersion characteristics that were structurally incorporated during the creation of the weapon are not significantly important, since they are compensated by the power of the nuclear projectile.

Now let's get back to ballistics. The creators of the 2S35 self-propelled gun state, I quote:

«… The 2S35 self-propelled howitzer has a “simultaneous fire attack” function, which allows you to hit a target simultaneously with several projectiles fired from one self-propelled gun and located on different flight trajectories».

Please note that a certain shooting possibility is described without specifying the shell consumption figure.

The firing mode of an artillery gun, which is called MRSI - several projectiles of simultaneous impact, to the firing mode, called " fire raid"has nothing to do with it. I'll explain why.

A fire raid is a Soviet artillery term that fires an artillery piece(s) at a specified number of shells, at multiple sight settings and multiple protractor settings, to hit a specific area. Any target in Soviet artillery was equated to a certain area, and its destruction by fire was appropriate - one of the methods of which was a fire raid.

In turn, the MRSI mode is a mode of shooting at a target, and not at an area, and if the creators declare the possibility of shooting in this mode, then they indicate its rate of fire accordingly.

For example, in a self-propelled Archer howitzers in MRSI mode, the consumption is 6 shells. That is, within one minute the gun is capable of firing 6 shells at different barrel elevation angles, which means on different trajectories.

If the consumption of shells in the supposedly identical Soviet MRSI " fire raid” is not indicated, then what kind of shooting possibility can we talk about?

As soon as the regime of multiple projectiles of simultaneous impact (MRSI) has not been called names in Russia: it has already been called names and “ a barrage of fire", And " pseudo gulp" Now to the existing two, " officially» added a third option ‒ « simultaneous fire attack" We have before us the most obvious indicator of the lack of terminology, which indicates a lack of science. For any science begins with a unified and understandable terminology.

Now I answer the question: why in the Russian artillery (in the existing paradigm) there cannot be an artillery gun with the ability to fire in MRSI mode. In one sentence, the answer will sound like this - in connection with the previous training of personnel and the absence of such a science as ballistics.

The firing mode of an artillery gun called MRSI (multiple rounds of simultaneous impact) describes a subtype of ballistics called Terminal ballistics. This term can be translated into Russian as terminal or final ballistics. Finite ballistics studies the interactions between projectile and target (as in, target). The terminal ballistics phase depends on impact speed, impact angle, projectile type, fuze parameters and target.

In the Soviet Union and early Russia in the 90s of the last century, they studied the ballistics that was inherited since the end of World War II. This ballistics had two subsections: internal and external. Nobody in the artillery of the Russian Federation was going to understand what changes in general ballistics took place during the 90s of the last century (as well as the first 10th of the 21st century). There was no such need at all; ballistics was classified as a not entirely necessary subject, and over time its existence was completely forgotten. But at the same time, those textbooks that have remained since 1979 have retained two main subsections of ballistics.

Meanwhile, at present, general ballistics is divided not into two, but into four sections, and includes, in addition to internal and external, intermediate and the above-mentioned terminal ballistics.

The main difference between Soviet ballistics and that in the West is a different understanding of the final result (expressed in English words end state). Soviet ballistics, as a science, set itself the final result, which was expressed in the creation of an artillery gun with firing range indicators without taking into account any accuracy standards.

In turn, Western ballistics set itself the final result of creating a weapon not only with a certain firing range, but also, and above all, with established understandable and clear standards of accuracy.

This is precisely the main problem, why ballistics is not taught to artillerymen at the Russian Artillery Academy. Why would a field artilleryman need to know how to design an artillery piece? Will he design it? No, only a few will do this, taking into account the interests exclusively of the customer and his representative. Therefore - a paradox - in view of previously accepted Soviet approaches and principles, ballistics is an unnecessary discipline in the training of a Russian artilleryman.

This is what led to the different final results set before one science in different systems. As a result, representatives of the customer (who are artillery officers of the Russian Federation), having no idea about ballistics in general, cannot order for themselves what, in their opinion, is modern. If the bulk of artillerymen do not know about the existence and purpose of artillery gun firing modes in general, then what can these people order and demand for themselves? And why do they need MRSI mode at all if they don’t have the slightest idea about it?

By the way, about the MRSI mode. This method first described as possible when firing from an artillery gun at the beginning of the twentieth century. This regime has been in active use of field artillery since the 40s of the last century. It was used not only in combat, but also to demonstrate the capabilities of field artillery.

With the development and improvement of technologies, primarily digital ones, with the constant integration of the trajectory of an artillery projectile into a 4-dimensional digital model of the firing range, range corrections, direction and time corrections, it has become possible to fire in MRSI mode with a flow rate not in 3, and more than 5 and even (in some variations, such as AMOS) and more than 10 shells.

In addition, due to changes in meteorology, accuracy has increased significantly, and as a result, a real need for combat use has emerged.

What accuracy of Russian artillery can we talk about or talk about if Russian artillery, 72 years after the end of World War II, continues to operate meteorological stations into whose probes hydrogen is pumped? I remind the creators of 2C35 that in the West the transition of meteorological stations to helium, which is safer to use, occurred in 1942, that is, 70 years ago.

To actually find out what multiple round simultaneous impact (MRSI) is, all you have to do is stop a few artillery officers in Russia (as well as from Belarus and Ukraine) and ask them about it. As an answer, you will hear only obscene derivatives, which are the best idea of the understanding of modern artillery science and art by these representatives of their armies.

Let's summarize. In accordance with the five points of the preliminary assessment, let’s look once again at the characteristics of the 155-mm self-propelled howitzer FH77BW L52 Archer, which look especially bright against the background of the characteristics of the 2S35 self-propelled gun:

Cost- cost of the project itself:

‒ Archer - from 1995 until it was put into service in 2016 - $450,000,000;
‒ 2S35 - has not undergone trial military operation since 2006, and the funds spent on development are a state secret.

Rate of Fire- rate of fire:

‒ Archer - 8-9 rounds per minute; in the multiple projectiles simultaneous impact (MRSI) mode - 6 projectiles;
‒ 2S35 - 7-8 rounds per minute; the MRSI firing mode is only stated, without a message or any correlation with the consumption of projectiles.

Accuracy- accuracy:

‒ Archer - circular probable deviation (CEP) in accordance with NATO requirements - up to 120 meters for unguided projectiles and from 25 to 3 meters for guided projectiles;
‒ 2S35 - no norms (as well as standards) for shooting accuracy were presented or formulated at all.

Range- firing range:

‒ Archer - from 30 to 50 kilometers for conventional and active-missile projectiles and up to 60 km when firing a guided projectile M982 Excalibur;
- 2S35 - up to 40 km, in accordance with those active-rocket projectiles that were developed in the USSR for the 2A36 (2S5) gun, no guided projectiles using the “ GLONASS» for 152 mm systems does not currently exist.

Intelligence- indicator of integration of this type of weapon with modern reconnaissance systems:

‒ Archer - integrates into the unified automated fire control system AFATDS (aka the modern NATO field artillery data system);
‒ 2S35 - only planned for integration into some “ Unified management system tactical level " This ESUTZ has been created since 1999, and until now has never been used in combat operations.

As a conclusion.

The 2S35 self-propelled gun is nothing more than a modernization, or it would be more correct to say - a claim to modernize the Soviet 152-mm self-propelled gun 2S5 " Hyacinth C" If the 2S5 did not have a turret, and the gun was mounted openly, copying the American 175-mm M107 field gun, then the 2S35 variant externally has all the attributes inherent in a modern self-propelled artillery gun. And nothing more.

And lastly, a final educational lesson for representatives of the artillery academy from the city of St. Petersburg. Firing range is a decisive advantage in an artillery duel only when two main problems have been previously solved artillery shooting: shooting accuracy and availability modern means intelligence. According to these two indicators - traditionally, soviet artillery and its successor, Russian artillery, never shone.
