A tandem active agent (2) contains the precursor charge (6) and the main agent (4). In a method of engaging a target (40), a tandem agent (2) is fired towards the target (40) at a specified time (t2) prior to impact with the target (40) whose precursor charge (6) is initiated, whereby a projectile (30) and fragments (20) are sent out as a focused sheaf (18) in each case ahead of the main active agent (2) in the direction of flight (10) towards the target (40), the Sheaf (18) is focused by giving the fragments (20) a radial velocity (VR) of at most one fifth of their axial velocity (VA).

Description

The invention relates to a tandem means of action, e.g. an ammunition, which contains a main means of action, e.g. a main charge, and a precursor charge. The precursor charge or the components formed from it, e.g. a projectile formed from an occupancy or a beam / spike, rushes ahead of the main active agent towards the target when the ammunition is used.

From the EP 3 171 121 A1 it is known to clear a path through explosive reactive armor (ERA) in the event of an attack on an armored vehicle from a short standoff distance. A jet or EFP (explosively formed penetrator) spike from a subsequent warhead follows a precursor jet generated by a transformable warhead that had cleared the ERA in the path of the attacking penetrator.

The object of the present invention is to propose improvements in relation to a precursor charge.

The object is achieved by a precursor charge (hereinafter also referred to as “charge” or “precursor” for short) according to claim 1. Preferred or advantageous embodiments of the invention and other categories of the invention result from the additional claims, the following description and the attached figures.

The precursor charge is intended for use in, i.e. for a tandem active agent. The invention is based on an intended tandem active agent that contains a main active agent. “Intended” means that the precursor charge is system-technically (i.e. in relation to the entire tandem effector including the precursor charge) and/or designed for a specific or a specific type of tandem active agent / main active agent and is set up for use there; e.g. designed for the geometry requirements etc. determined thereby. In other words, a relevant tandem active agent/main active agent is assumed to be known with regard to its geometry/properties etc.

The precursor charge extends along a longitudinal axis. The charge is set up to be attached as intended in the direction of a flight direction of the tandem active means that coincides with the longitudinal axis in front of its main active means. In an intended assembly state or use of the charge in the tandem active means, an entire tandem active means is created in which the charge—seen in the intended direction of flight of the tandem active means—is arranged in front of the main active means. In addition, the charge is attached to the main active means/in the tandem active means, in particular attached to the main active means or a common carrier of the tandem active means.

The precursor charge includes a case and explosives placed within the case. In particular, the shell forms the outer geometric shape of the precursor charge and/or acts as a housing for the other components of the precursor charge.

The precursor charge also contains a projectile device attached to the hull. The projectile means is--in cooperation with the explosive--set up to emit an armor-piercing projectile when the explosive is deployed. This is done in such a way that the projectile is emitted along the longitudinal axis in the intended direction of flight of the main active agent and thus of the precursor charge, and then—after sending out—hurries ahead of the main active agent. "Race ahead" means that it moves at a higher speed than the main means of action and moves away from the main means of action with a differential speed in the direction of flight.

The precursor charge also contains a fragmentation agent. This is also attached to the case. The projectile means is - also in cooperation with the explosive - set up to form and emit a focused fragmentation sheaf when the explosive is converted. The splinter sheaf is a sheaf that is formed from a large number of splinters and can also be referred to as a splinter cloud. The sheaf, like the projectile, also rushes ahead of the main agent after formation and emission in the direction of flight. The focus of the sheaf is achieved as follows: A radial speed of the fragments is at most one fifth of their axial speed ("radial / axial" is related to the longitudinal direction and thus the direction of flight). In particular, the radial speed is at most one tenth, twentieth, fiftieth or hundredth of the axial speed. The velocity distribution is achieved through design measures of the precursor charge, as explained below. In other words, the sheaf forms a splinter cloud that precedes the main agent.

In particular, fragments/explosion elements with different speed characteristics can also occur during the conversion of the explosive, but these do not count as part of the sheaf.

In addition to conventional ferrous and non-ferrous alloys, materials that react reactively when interacting with an effector/defense body sent out by an active protection system of the target and release other forms of energy in addition to kinetic energy, such as heat or pressure, come into consideration as fragmentation material.

The explosive is in particular one with a high detonation speed in order to achieve high projectile/fragment velocities.

The comparatively low axial speed results in a strongly bundled sheaf/cloud of fragments, which essentially moves along the longitudinal axis or direction of flight in front of the main active agent and hardly diverges. In other words, the fragments are focused along the longitudinal axis/direction of flight.

The projectile means is in particular a projectile-forming means, in particular a projectile-forming shaped charge. The differential speeds of projectile and sheaf to the main active means can differ, but in particular are the same - within the framework of the usual tolerances in this regard.

A "precursor" charge results from the fact that both the projectile and fragments "run ahead" of the main agent.

A corresponding armor-piercing projectile can be detonated at a distance of approx. 10-15 m ("stand-off") from a target to be attacked. On the other hand, an active agent that works with a shaped charge spike instead of a projectile, for example, must be ignited at a maximum distance / stand-off of approx. 1m from the target. This alone results in an increased stand-off for the precursor charge proposed here.

The projectile can produce an initial effect, namely penetrating armor, for example pre-/reactive armor of an armored target. The fragments create a further effect, namely the destruction / inactivation / rendering harmless of effectors, which the target opposes / sends towards the approaching tandem agent as an active protective measure. In this respect, the proposed precursor charge has a multi-effect.

The invention therefore assumes in particular that the effectors emitted by the target or its defense system/active protection system for protection against the tandem active means are ballistic defense bodies. According to plan, the effectors are used to ward off incoming weapons/ammunition by triggering them/rendering them harmless by impacting the effector at a safe distance from the target.

According to the invention, there is thus a multi-effect precursor charge with an increased stand-off for overcoming active protection systems. The result is a precursor charge (also "precursor warhead") with an increased stand-off for tandem active systems (tandem active means), which makes it possible to overcome active protection systems of heavily armored targets by destroying approaching effectors of active protection systems with a focused fragmentation sheaf , before they reach the main active agent (main charge) of the tandem warhead (tandem active agent) within effective range. The invention thus allows active protection systems with fired effectors to be overcome.

The invention is based on the idea of creating a technical solution for overcoming active protection systems. The invention is based on the finding that the previous options known from practice include the following: In order to circumvent active protection systems, it is possible to exploit blind spots in the protected area of the systems. It is also possible to increase the approach speed of your own / attacking effectors (active agents) in order to reduce the available reaction time of the active protection system.

The invention is based on the following basic idea: the precursor charge is based on a pre-cursor with an increased standoff due to the projectile, in particular a projectile-forming charge. When converting the explosive in the charge, a cloud of fragments/spray of fragments is released or generated simultaneously with the projectile, in particular from the shell and/or from the artificial fragments integrated for this purpose. The fragments (sheaf / cloud) are generated in vectorial addition with the projectile speed (original speed of the entire tandem active agent) as a strongly focused fragmentation sheaf in the direction of the shot (longitudinal axis / direction of flight). The sheaf, together with the emitted / emerging projectile of the projectile means, rushes ahead of the non-detonated part (main means of action) of the tandem system of action / means. The splinter sheaf acts as a protective shield, which destroys or implements opposing effectors of active protection systems before they can get into critical proximity to the main charge (main agent) of the tandem system. The fragments are - in particular in their spatial distribution and / or mass and / or speed - adapted in such a way that they do not fight the actual hardened / armored target, but can hit and destroy approaching effectors (sent out by the active protection system of the target towards the approaching tandem weapon) with the highest possible probability.

According to the invention, the effect of the precursor charge with an increased stand-off (projectile agent) is expanded to include a splinter effect (splinter agent) which, compared to the natural splinter effect, is specifically adapted in terms of effective range and splinter power so that it can be used to combat effectors from active protection systems. In the overall concept of a tandem active system (tandem active agent) with such a pre-curser (charge), the ability to overcome active protection systems with fired effectors arises.

The invention is particularly suitable for a tandem active agent in the form of a direct fire guided ammunition with a tandem active system consisting of precursor charge/main active agent.

In a preferred embodiment, the splintering means contains a splinter insert which has the shape of a cylinder jacket with respect to the longitudinal axis and/or which is arranged in particular on an inner surface of the casing.

On the one hand, this results in a radial splitter insert. On the other hand, this reinforces in particular the outer shell or shell and forms radially outgoing splinters of a defined mass and geometry. It can be designed as a pre-fragmented body or loose individual fragments. The fragments of the radial fragmentation insert are designed (mass/size) in such a way that they receive a relatively small radial velocity component from the detonation of the explosive and, in vectorial addition with the movement velocity (before the explosive is converted) of the entire tandem active agent, a (after the conversion of the explosive) maintain a strongly forward-directed flight direction (above-mentioned distribution of radial / axial speed of the fragments).

In a preferred embodiment, the splinter means contains a splinter body which has the shape of an annulus running transversely to the longitudinal axis. This results in an axial splinter body. This is located in particular with regard to the longitudinal axis on the front side of the precursor charge, which is intended to point in the direction of flight (seen in the direction of flight "in front") and serves to generate a fragmentation effect directed in the longitudinal axis of the charge / direction of flight. It can be designed as a pre-fragmented body or loose individual fragments. The fragmentation body is designed in particular at the interface to the explosive in such a way that the acceleration during its detonation along the longitudinal axis of the charge does not spread too much (radial velocity of the fragments is much smaller than their axial velocity, e.g. factor 1/100, 1/1000 or even smaller). takes place.

In a preferred embodiment, the projectile means contains a coating forming the projectile in the form of a disk running transversely to the longitudinal axis. The occupancy is in particular a flat / dome-like / conical metal insert that goes off as a coherent projectile when the explosive detonates. The assignment thus forms the projectile for combating the target or its preliminary / reactive armor.

In a preferred variant of this embodiment, the disc is arranged concentrically inside the above-mentioned splinter body in the form of the circular ring. Occupancy (disk) and splinter body (annular ring) thus form a continuous overall disk at the same axial position (longitudinal axis), which in particular closes off the precursor charge at the front, seen in the longitudinal direction or intended flight direction. This creates a particularly favorably packed precursor charge.

In a preferred embodiment, the projectile means and the fragmentation means are matched to one another in such a way that the projectile precedes the sheaf or cloud of fragments or moves with the foremost front in the direction of flight. The projectile is therefore not impeded or disturbed in its flight towards the target by the eventual collision of fragments and effectors of the active protection system of the target, since it has already passed the corresponding collision area at this point in time.

In a preferred embodiment, the precursor charge is round, in particular circular, in particular rotationally symmetrical in cross-section with respect to the longitudinal axis. This applies in particular to their outer contour. This allows a particularly good integration with the main active means or tandem active means, which are also generally designed to be round or circular. In particular, this applies to the circular shape, especially in the form of ammunition / tandem means of action for firing from circular weapon barrels.

The invention is also solved by a tandem action means. This contains the precursor charge according to the invention and the main active agent explained in this context, the precursor charge or the precursor being attached as intended in a direction of flight of the tandem active agent that coincides with the longitudinal axis in front of its main active agent.

The tandem active means and at least some of its possible embodiments and the respective advantages have already been explained in connection with the precursor charge according to the invention.

In a preferred embodiment, a transverse extent transverse to the longitudinal axis, in particular an outer diameter of the precursor charge, corresponds to that, in particular the caliber, of the main active agent, in particular the entire tandem active agent or the corresponding ammunition. This creates a particularly uniform tandem active agent.

In a preferred embodiment, the main agent contains a main charge. As described above, this allows the main charge to bypass the target's active defenses with the help of the fragmentation sheaf; as well as using the projectile on the target's pre-/reactive armor past it.

In a preferred embodiment, the main agent contains a shaped charge. Such is particularly effective against certain heavily armored targets.

In particular, the projectile means contains a comparatively small shaped charge as at least part of the projectile means for forming the projectile; the main means of action is a larger, i.e. comparatively large, shaped charge for actually combating the target. If the active protective measure was repelled by the fragmentation sheaf, and the projectile was able to overcome a preliminary armor of the target, the main means of action can now be used on the unprotected or only protected by its main armor. This can then be overcome by the main means of action, so that the main means of action can act against the target.

The object of the invention is also achieved by a method according to patent claim 12 for combating a target with the aid of a tandem weapon. The method assumes that the tandem agent contains a main agent and a precursor charge. The precursor charge, in turn, contains a projectile agent which, when initiated, emits an armor-piercing projectile. The Precursor Charge also contains a shard agent which, when initiated, emits shards in the form of a focused sheaf. The initiation is in particular the above-mentioned implementation of an explosive in the precursor charge. For the splinters in the sheaf, as explained above, their radial speed is at most one-fifth of their axial speed; a corresponding speed is thus imparted to the splinters in the sheaf.

The precursor charge is in particular the precursor charge according to the invention. Alternatively or additionally, the tandem active agent is in particular the tandem active agent according to the invention.

In the method, the tandem gun is fired toward the target. At a specific point in time, which is before the tandem active agent hits the target, the precursor charge is initiated, in particular the explosives contained therein are detonated. As a result, the projectile from the projectile means and the fragments as the sheaf from the fragmentation means are each sent out ahead of the main active means in the direction of flight towards the target.

The method and at least some of its possible embodiments and the respective advantages have already been explained in connection with the precursor charge according to the invention and the tandem active agent according to the invention.

The point in time is in particular the point at which the tandem active means reaches a specific distance from the target. Such a distance can be detected particularly easily and precisely and is therefore particularly suitable as a triggering criterion for the initiation described above.

In a preferred embodiment, the point in time selected is that at which an active defense system of the target sending out a defense body towards the ammunition detects the ammunition or at least sends out a defense body. The point in time thus corresponds in particular locally to when the tandem active means reaches/passes a detection point of the active defense system. In this way, a particularly effective defense against the effectors sent out by the target is achieved.

In a preferred embodiment, the point in time is chosen such that the sheaf strikes defense bodies at such a distance from the main means of action that is greater than an effective range of the defense bodies. Thus, at the point in time at which the defense body is destroyed by the sheaf, the main agent is outside the effective range of the defense body and cannot be impaired or destroyed by it. The effective range also includes effects that result from the combating / destruction of the defense body by the splinters. In other words, the defense bodies are fought at a safe distance from the main agent. The defense bodies and their behavior when combated by the splinters are assumed to be known.

In a preferred embodiment, the time is chosen as the one at which the tandem active means is between 5 and 25 meters, in particular 10 and 15 meters, in particular 12.5 m in front of the target. Such distances have proven to be particularly advantageous in practice.

The following generally applies to the present invention: details of the design of the precursor charge and/or the main agent or tandem agent depend heavily on the target that is potentially to be attacked or its expected properties. In particular, these are properties of its armor (main / preliminary / reactive armor) and the active protection system. The design mentioned concerns, among other things, the selection of materials, dimensions, geometries of the precursor charge, number, size and nature of fragments, projectile used, explosives, design of the shell, etc. Corresponding values are therefore dependent on the planned use of the charge / the tandem agent and can or must be individually adapted and found, for example, through tests, empirical considerations, estimates, etc. within the framework of customary designs.

The invention is based on the following findings, observations and considerations and also has the following embodiments. The embodiments are sometimes also referred to as “the invention” for the sake of simplicity. The embodiments can also contain parts or combinations of the above-mentioned embodiments or correspond to them and/or optionally also include embodiments that have not been mentioned before.

The present invention can be summarized as follows: The invention includes in particular the expansion of an armor-piercing explosive charge (tandem agent) with increased stand-off (achieved by the projectile-forming charge as a projectile agent) by an additional effect in the form of a directed and focused fragmentation sheaf, which is not the combating the actual armored target, but is designed in terms of fragment density, fragment mass and fragment speed to eliminate effectors of active protection systems fired from the target.

By using such an explosive charge (explosive and fragmentation agent) as a precursor within a tandem agent consisting of a precursor (charge) and a main charge (main agent), the ability is created to overcome reactive armor of the target at the same time as the precursor charge is initiated ( Target projectile), as well as additionally existing active protection systems whose effectors are fired in the direction of the approaching tandem active agent.

The function and effect of the invention can be summarized as follows: If the precursor is initiated at an increased distance from the target, it releases an armor-piercing projectile and a fragmentation sheaf, which precede the part of the tandem active agent that has not yet been initiated. The projectile-forming charge has the task of breaking through existing reactive armor, while the fragmentation sheaf acts as a kind of protective screen for the slower-flying main charge/agent and destroys all effectors that are on the trajectory of the main agent. This ensures that the main weapon can work against an unprotected target's main armor.

Further features, effects and advantages of the invention result from the following description of a preferred exemplary embodiment of the invention and the attached figures. Show, each in a schematic principle sketch:

• 1 a tandem active agent according to the invention,
• 2 the tandem active agent according to the invention when used in a method for combating a target.

1 shows a tandem active agent 2, which contains a main active agent 4, here a main charge indicated only symbolically, and a precursor charge 6 firmly attached to this. Precursor charge 6, main active agent 4 and tandem active agent 2 all have the same longitudinal axis 8 and extend along it. An intended flight direction 10 of the tandem active means 2 coincides with the longitudinal axis 8 and is in 1 indicated by an arrow. Seen in flight direction 10, precursor charge 6 is attached in front of main agent 4. The flight direction 10 is the direction in which the tandem active means 2 flies when it is used or operated as intended.

The charge 6 has a shell 12 which is filled with explosives 14 . The ignition of the explosive 14 is represented symbolically by an arrow 15 . A fragmentation means 16 is attached to the shell 12 . This is set up to form a focused sheaf 18 from a large number of fragments 20 during the conversion of the explosive 14 , which is ahead of the main active agent 4 in the direction of flight 10 . In 1 four such splitters 20 are shown as an example.

The speed V of a respective fragment 20 is made up of two components, namely the axial speed VA lying parallel to the direction of flight 10 and the radial speed VR lying radially. The axial velocity keit VA in turn contains the current basic speed V0 of the tandem active means 2 at the moment of the conversion of the explosive 14 and thus also the precursor charge 6 and the splitter 20 before or during the conversion of the explosive 14 as the first addend Additional axial velocity imparted to fragments 20 by reaction of explosive 14, resulting in axial velocity VA greater than base velocity V0. The radial velocity VR is also imparted to the fragments 20 by the reaction of the explosive 14 . The precursor charge 6 is dimensioned with regard to the explosive power of the explosive 14 in coordination with the materials and the geometry of the fragmentation means 16 and the shell 12, among other things, such that the radial speed VR here is only one twentieth of the axial speed VA. Conditions are in 1 presented qualitatively.

The splitter 16 is made up of two components. On the one hand, it contains a splinter insert 22 . With respect to the longitudinal axis 8 , this has the shape of a cylinder jacket and is arranged on an inner surface 24 of the casing 12 pointing radially inwards. On the other hand, the splinter means 16 contains a splinter body 26 which has the shape of a circular ring 27 and runs concentrically and transversely to the longitudinal axis 8 . The circular ring 27 thus extends in a transverse plane to the longitudinal axis 8.

The precursor charge 6 also contains a projectile means 28. This is also attached to the shell 12. It is also set up to emit an armor-piercing projectile 30 when the explosive 14 is converted, which then—like the fragments 20 in the sheaf 18—precedes the main active agent 4 in the direction of flight 10 . In 1 the projectile 30 is indicated symbolically. The projectile 30 then also has an axial velocity VA, which is composed of the above-mentioned basic velocity V0 of the projectile means 28 as the first summand and an additional velocity imparted by the conversion of the explosive 14 as the second summand. In the present case, both axial velocities VA of fragments 20 and projectile 30 are the same.

In the present case, the projectile means 28 contains a coating 32 that forms the projectile 30 . This is configured here—corresponding to the splinter body 26 —as a disk 33 running transversely to the longitudinal axis 8 . The disc 33 is arranged concentrically within the circular ring 27; Fragmentation body 26 and occupancy 32 are therefore located in the same axial position of the longitudinal axis 8 and together form an uninterrupted end face 34 of the precursor charge 6.

The projectile means 28 is thus arranged/fastened/held on the casing 12 here by means of a part of the splinter means 16, namely the splinter body 26.

The entire precursor charge 6 is round in cross-section relative to the longitudinal axis 8, in this case circular. In the tandem active agent 2, a transverse extent Q transverse to the longitudinal axis 8, here a diameter, of the precursor charge 6 corresponds to that of the main active agent 4.

2 shows - strongly symbolized - the use of the tandem active means 2 1 against a target 40, here a battle tank, which is equipped with both a preliminary armor 42, here a reactive armor, in front of a main armor 43 and with an active protection system not shown in detail. 2 thus shows a combat scenario with tandem agent 2 with precursor charge 6 with increased stand-off (thanks to projectile 30) with an extended spectrum of action (sheaf 18 of fragment 20). Upon detection of the attacking tandem means of action 2, the active protection system of the target 40 emits ballistic defense bodies 44 in the direction of the tandem means of action 2 in order to intercept it. 2 symbolically shows only one of the defense bodies 44.

At a point in time t1, the tandem active means 2 has already been fired or shot down or started towards the target 40 and is in flight towards the target 40 along the direction of flight 10 which coincides with its longitudinal axis 8 . The tandem active means 2 therefore flies in the direction of target 40.

At a later point in time t2, the tandem active means 2 initiates its precursor charge 6 (indicated by an asterisk). In the present case, the initiation takes place by detonating the explosive 14. The fragmentation means 16 for emitting the fragments 20 and the projectile means 28 for forming and emitting the projectile 30 are thus initiated. The point in time t2 is selected by the tandem means of action 2 such that it is the point in time at which the active protection system of the target 40 has detected the tandem means of action 2 and initiates its countermeasure, namely the defense body 44 is sent out to the tandem means of action 2 . At time t2, the tandem active means 2 is at the so-called detection point 48 of the target 40, i.e. at that distance from the target 40 at which the active protection system detects the tandem active means 2 and initiates the countermeasure (emission of the defense bodies 44).

At a later point in time t3, the result of the ignition of the precursor charge 6 can be seen: both the projectile 30 and the sheaf 18 (here indicated by dashed lines) of the fragments 20 (four pieces are represented as representatives) now rush ahead of the main active means 4 in the direction of flight 10 . It can be seen here that the projectile means 28 and fragmentation means 16 are matched to one another in such a way that the projectile 30 does not precede the sheaf 18 but moves with the sheaf 18 at its foremost front 46 as seen in the direction of flight 10 . The defense body 44 is now moving counter to the direction of flight 10 towards the remaining main active means 4 of the tandem active means 2 . The (P-charge) projectile 30 rushes ahead of the main charge 36 (main active means 4) together with a dense (fragment) sheaf 18 and passes the encounter point (intercept point 50) of the active protection system of the target 40. The main charge 36 approaches the encounter point (Intercept point 50). The intercept point 50 is the distance from the target 40 at which the defense body 44 is scheduled to hit the main active agent 4 and intercept/destroy/render it harmless (see point in time t5, below).

At a later point in time t4, however, the leading sheaf 18 of the splinters 20 and the defense body 44 meet. The defense body 44 is destroyed or intercepted by the fragments 20, which in turn is indicated by a star. The projectile 30 has meanwhile passed the intercepting body 44 . The (splinter) sheaf 18 thus reaches the effector (defense body 44) of the active protection system before it reaches the meeting point (interception point 50). The effector (defence body 44) is destroyed by the (splinter) sheaf 18.

This prevents the following situation, which should have occurred at a later point in time t5 as planned, which is why it 2 is only indicated by dashed lines. The purpose of the active protection system of the target 40 would be that the defense body 44 and the main means of action 4 meet at the interception point 50 and the main means of action 4 would be destroyed by the defense body 44; again symbolically indicated by a star. The main active agent 4 could no longer reach the target 40 in this way. In fact, however, the defense body 44 has already been destroyed at the previous point in time t4, and the effects of the destruction—far enough away from the main agent 4—have decayed. The main active agent 4 can continue to fly towards the target 40 unhindered. Thanks to the successful defense of the defense body 44 by the sheaf 18, the main active agent 4 is now actually approaching the target 40.

At a later point in time t6, the projectile 30 arrives at the target 40 and penetrates its preliminary armor 42 and thus prepares a path 52 for the main active agent 4 through the preliminary armor 42 on or along the flight direction 10 .

At a later point in time t7, the main active agent 2 then reaches the target 40 or its main armor 43 on the path 52 through the preliminary armor 42 destroyed or removed there, can overcome this and finally act against the target 40, again indicated by a star.

As a result, the (P-charge) projectile 30 successfully reaches the target 40 at the point in time t6 and can act against the preliminary armor 42 . The target 40 is now unprotected or only protected by its main armor 43 and the main charge 36 can act against the main armor 43 of the target 40 at time t7.

Precursor charge (6) according to one of the preceding claims, characterized in that the projectile means (28) contains a coating (32) forming the projectile (30) in the form of a disc running transversely to the longitudinal axis (8). Precursor charge after (6) claim 3 and 4 , characterized in that the disc (33) is arranged concentrically within the annulus (27). Precursor charge (6) according to one of the preceding claims, characterized in that the projectile means (28) and the fragmentation means (16) are matched to one another in such a way that the projectile (30) precedes the sheaf (18) or follows it in the direction of flight (10) front line (46) moves. Precursor charge (6) according to one of the preceding claims, characterized in that the precursor charge (6) is round in cross-section relative to the longitudinal axis (8). Tandem active means (2) with the precursor charge (6) according to one of the preceding claims and the main active means (4), the precursor charge (6) being attached in front of the main active means (4) as intended. Tandem active means (2) after claim 8 , characterized in that a transverse extent (Q) transverse to the longitudinal axis (8) of the precursor charge (6) corresponds to that of the main active agent (4). Tandem active means (2) according to one of Claims 8 until 9 , characterized in that the main active agent (4) contains a main charge (36). Tandem active agent according to one of Claims 8 until 9 , characterized in that the main charge (36) contains a hollow charge (38). Method for combating a target (40) using a tandem agent (2) that contains a main agent (4) and a precursor charge (6), which in turn contains an armor-piercing projectile (30) that emits a projectile agent (28) and a includes fragmentation means (16) emitting fragmentation (20) in the form of a focused sheaf (18) upon initiation, wherein: - the tandem active agent (2) is fired at the target (40), - the precursor charge (6) is initiated at a specific point in time (t2) before it hits the target (40), whereby the projectile (30) and the fragments (20) as the focused sheaf (18) each fall to the main agent (2 ) are sent out ahead of the target (40) in flight direction (10), - the sheaf (18) being focused by giving the fragments (20) a radial velocity (VR) of at most one fifth of their axial velocity (VA). procedure after claim 12 , characterized in that the point in time selected is that at which an active defense system of the target sending out a defense body towards the ammunition detects the ammunition or at least sends out a defense body. Procedure according to one of Claims 12 until 13 , characterized in that the point in time is selected such that the sheaf hits defense bodies at such a distance from the main means of action, which is greater than an effective range of the defense bodies. Procedure according to one of Claims 12 until 14 , characterized in that the moment in time is chosen as that at which the tandem active means is between 5 and 25 meters in front of the target.
