Definitions

  • This invention relates to munitions systems, and methods for use thereof.
  • this invention provides a new bombing system capable of delivering a more accurate and destructive strike to an intended target.
  • Some current defensive war techniques include the use of natural and manmade tunnels and underground compartments to store important equipment and manpower to prevent their location and destruction during air attacks. Most current bombs cannot penetrate such compartments, leading to extended conflicts that may last years and cost millions of lives, either as a result of inaccurate targeting or insufficient explosive power.
  • the lack of ability to do so hitherto is a frustration with defence planners in the western world and has allowed rogue nations and organizations to utilise natural caves or create hardened underground facilities for refuge, storage, nuclear weapons production, ballistic missile production, biological and chemical warfare and experimentation and materials production.
  • the principle behind the invention resides in delivering successive bombs to the same target position to increase the explosive effect at the designated target. This is achieved by connecting the bombs through a tether, preferably a stretchable nylon rope capable of withstanding forces during payload delivery.
  • a system of deployment has also been devised that has the capability of providing severe damage to aboveground and underground facilities through the concentration of "shock” or "pulse” waves that are generated during underground detonation of explosive devices.
  • a munitions system comprising a munitions train having a front and a rear, said munitions train having at least two vehicles tethered one to another by a tether between successive vehicles thereby providing a leading penetrating vehicle at the front to penetrate a target and at least one trailing vehicle to follow said leading penetrating vehicle, said munitions train having a greater drag coefficient toward the rear.
  • successive vehicles are tethered tail to nose.
  • said greater drag coefficient toward the rear is implemented by a deployable mechanism.
  • said greater drag coefficient toward the rear is implemented by a drag device forming the rear of the munitions train, and secured to the tail of the rearward said at least one trailing vehicle.
  • said greater drag coefficient toward the rear is implemented by a drag device forming the rear of the munitions train, and tethered to the tail of the rearward said at least one trailing vehicle.
  • said drag device comprises a parachute device.
  • the parachute device is preferably in the form of a ballute.
  • a ballute is an inflatable device used to increase drag of the vehicle to which it is attached.
  • the ballute combines features from the two devices that give it its name; the two devices being an inflatable balloon and a parachute
  • the drag device is selectively deployable, so that it can be deployed after a predetermined time, at a predetermined height, at a predetermined location, or in an alternative, under remote control.
  • the drag device is also selectively deployable so that it can be undeployed or otherwise rendered less effective or inoperative upon achieving target positioning and correct alignment, in order to increase the velocity of said munitions train for a larger destructive force on impact.
  • Such selective deployment may be achieved by a release mechanism for the parachute device.
  • the release mechanism may be activated remotely, or by on-board device sensors such as an altitude sensor or accelerometer.
  • the tether may include a cord of a length of up to 500 m.
  • said cord has a length of from 50 m up to 500 m. More preferably, the cord has a length of from 100 m up to 500 m.
  • the cord has a length of about 150 m.
  • the cord length may be longer between successive trailing vehicles to allow for increasing impact crater depth as the munitions train impacts the target. This minimises interference of incoming vehicles with the ejecta from preceding explosions.
  • said cord is a stretchable cord for cushioning shock and impulses while being capable of withstanding forces imposed upon it by the bombs, resistance of the air and wind loading.
  • the stretchable cord may comprise a nylon line.
  • said tether includes a dispenser to dispense said cord, said dispenser being mounted on the rear of each said vehicles.
  • the dispenser is adapted for orderly storage of said cord, to allow said cord to be dispensed without becoming tangled.
  • This adaptation may be provided by a cylindrical structure against which the cord is laid.
  • the dispenser includes guide means for guiding the cord as it is dispensed to thereby further obviate the risk of tangling.
  • the dispenser incorporates cord length adjustment means to set the length of the cord to a desired predetermined length.
  • cord length adjustment means to set the length of the cord to a desired predetermined length. This allows the length of the cord to be adjusted before the munitions train is loaded on an aircraft or deployed. This can be useful where different terrain might yield different impact crater depth, allowing the distance between successive vehicles to be adjusted accordingly.
  • leading penetrating vehicle has a lower drag coefficient than the drag coefficient of said at least one trailing vehicle, to present the least wind resistance. This will assist in tension being maintained in the tether.
  • leading penetrating vehicle is a guided bomb.
  • leading penetrating vehicle is an armed guided bomb.
  • the leading penetrating vehicle may be guided in the sense that it is capable of being steered onto a target either through the use of guide vanes or through propulsion means.
  • the leading penetrating vehicle may comprise a self- propelled missile.
  • said at least one trailing vehicle is selected from one or more of a bomb, and a vessel containing a substance or a mixture of substances.
  • the munitions system is in combination with a carrier therefor, the combination being releasable as a unit from an aircraft and the munitions system being subsequently deployable from the carrier.

  • the substance contained in any one vehicle need not be explosive, but may form an explosive when admixed with another substance.
  • this may be embodied in said second munitions train comprising said vehicles alternately containing ammonium nitrate and fuel oil (such as diesel) to create "anfo" in-situ.
  • said second munitions train comprises said vehicles containing TNT.
  • the step of detonating said explosive substance may be carried out with a conventional guided bomb or missile delivered into or onto said subterranean shaft filled with said explosive.
  • the detonation is initiated on top of the explosive, so that the force of the resultant blast is maximised in the ground, rather than dissipated in the air.
  • said method includes a further subsequent step of delivering a heavier than air gaseous fuel into said subterranean shaft (or fractured rock standing in its place), allowing said fuel to settle and seep into air spaces surrounding rock and fracture therein, and detonating said gaseous fuel after a predetermined period of time.
  • a method of destroying an underground structure comprising steps of: locating said underground structure, and generating underground damage in the vicinity of said underground structure according to the above described method.
  • said subterranean shaft is formed and utilised in more than one position around said underground structure to create superposition of pulse waves from explosions to concentrate energy upon the underground structure.
  • Generating underground damage from more than one position around the underground structure would be expected to create a plurality of pulse waves that wiif interact and cause amplification and intensification of the energy upon the underground structure.
  • said subterranean shafts are formed and utilised in three positions surrounding said underground structure.
  • the location of the underground structure can, if necessary, be determined by remote geophysical "mapping" of hidden underground tunnels, caves and rooms prior to bombing.

  • Remote imaging such as satellite imaging, may be used to provide information on target positioning.
  • Calculation on the positioning and number of munitions required for an attack may be determined, so that an efficient and focussed strike can be taken upon the primary target. This can also be carried out by the central computer.
  • the geophysical underground 3-D mapping process may involve: emplacing geophones on the ground dropped from a great height which telemetrically report their exact location and elevation; using conventional bombs as the seismic energy source also reporting their accurate detonation time and exact 3 dimension location back to a satellite (reporting of detonation time and location can either be from the bomb up to the point of detonation, from the delivery means such as the aircraft, or from independent means such as satellite); having geophones report the reflection data telemetrically to satellite and then to data processing centres as is presently done in marine seismic operations; and processing the seismic reflection data to create accurate 3-D underground images.

  • the parachute 115 is deployed, causing the pallet 113 to nose upwardly momentarily and experience the full horizontal air velocity. Within a short period of time thereafter, the pallet 113 resumes a horizontal attitude and is substantially slowed in the horizontal direction.

The motion of the pallet 113 is thus stablised, thereby allowing the sequential deployment of the munitions system 110, in a manner similar to previous embodiments.
  • This arrangement has several advantages, one of which is primarily related to safety. Because the munitions system 110 is not deployed until it has departed the aircraft, there is no possibility of the tether cords in the munitions string fouling and remaining attached to the aircraft. A further advantage is that the vertical drop before the munitions system 110 is deployed is minimal and so there is no significant loss in height. Additionally, the dynamic tensions in the tether cords are reduced, as unfurling of the tether cords occurs at a stage where the horizontal velocity component of the munitions system has reduced significantly.

  • the total unfurled length of a munitions string in the embodiment may be around 3,000 m, based on an average separation of 150 m between 20 munitions. This may be less than the operating ceilings of aircraft that may be used for deploying such a system, typically 11 ,900 m in the case of a B52.
  • the separation between the munitions in the munitions string may be varied along the length of the string according to the depth of underground penetration required and the nature of the material to be removed by the munitions.
  • the underlying principle is to ensure that each munitions enters the crater after the ejected debris from the previous explosion has dissipated sufficiently so as to not to cause deflection of the munitions or premature detonation.
  • the separation of munitions towards the front of the munition string may be smaller than those towards the rear.
  • the separation distances may gradually transition from as little as 50 m for front end munitions up to 150 m for rear end munitions.
  • a leading munition with a special piercing capability to initiate cratering.
  • Such a munition may possess a plasma generating charge that in effect melts the rock on contact.
  • a further modification could be to utilise a powerful aircraft as a "tug" to progressively launch a string of bombs from the ground and tow them to a target site for release at high altitude allowing a longer standoff position.
  • the method of launching would entail the aircraft taking off with a long towline (say 2 km) to the lead bomb.
  • the elasticity of the nylon towline would create a staged momentum transfer to the lead bomb, which after becoming airborne would transfer successively to each bomb as it launched.
  • the towline in this instance would require a high breaking strain (say 5 tonne or higher).
  • the method described herein provides un-survivable underground shock waves both devastating to human life and structures containing cavities alike.
  • an extermination bombing system comprising the following steps: 1. Locate and three-dimensionally map underground caves, tunnels and structures utilizing modified oil exploration techniques operating from military aircraft;
  • Operations 3 through to 6 can be repeated as required to complete extermination.
  • operations 2 through to 6 can be conducted simultaneously at three locations 3km apart each at the corner of a triangle to create a coalescing Shockwave within the contained area.
  • the locations of underground voids caverns, tunnels and structures can be mapped from afar by utilising geophysical underground 3-D mapping technology. This can be achieved by :
  • This process could be repeated after attack to measure the extent of damage.
  • the extermination system has the advantage that it can only be deployed by and defended against by advanced nations, therefore is a natural weapon against terrorism and rogue nations.
  • the method can be simply installed on existing weapons.

Abstract

L'invention concerne un système de munitions et un procédé d'utilisation de ce système consistant à lancer des bombes successives sur une même cible afin d'augmenter l'effet d'explosion sur cette cible. Ce système (10) de munitions comprend une chaîne de projectiles dont une partie au moins sont des bombes. Ces véhicules de projectiles sont attachés les uns aux autres et comprennent un véhicule (11) de tête conçu pour guider la chaîne jusqu'à la position de la cible, ainsi qu'une pluralité de véhicules (21) de projectiles traînés. Les véhicules (21) de projectiles sont attachés les uns aux autres au moyen d'un cordage (13) extensible. Un dispositif ralentisseur tel qu'un ballute (29) est attaché au dernier véhicule (21z) de projectile tracté. La présence de ce dispositif (29) ralentisseur permet d'assurer que les liens entre les véhicules de projectiles successifs restent tendus.
